Feeding chickens under the forest is an economic innovation farming model under forest, which has good economic benefits and broad development prospects. In this paper, the effects of feeding chicken under the forest on forest and grass, soil physicochemical properties, soil microbial diversity, and insect population were summarized,and the corresponding development measures were put forward based on practical production. In the modes of feeding chickens under the forest, chicken manure, as a green organic fertilizer, can effectively increase economic income. However, this model also has some disadvantages, such as damaging plant growth and reducing plant diversity. When the density of chickens under the forest is controlled reasonably, it is beneficial to maintain good soil ventilation and water permeability. However, the high-density and long-term activities of chickens may lead to the changes of soil physical and chemical properties, and the growth of trees is hindered by poor soil quality. In the process of production, the modes of feeding chicken under the forest is beneficial to increase the variety and quantity of soil microorganisms, promote the decomposition of soil organic matter and the transformation of nutrients, and thus improve soil fertility. At the same time, it can reduce the occurrence of pests, promote the healthy growth of plants, save feed, and reduce the cost of disease and pest control. The development of feeding chicken under the forest should be based on local conditions, scientific site selection and layout, targeted improvement of the vegetation in the breeding area, reasonable determination of breeding density, time and scale, implementation of regional rotational grazing system, and strengthening disease prevention and control. This paper provides references for promoting the high-quality development of the feeding chicken under the forest.

As an abiotic stress factor, UV-B radiation significantly impacts plant morphological development, physiological and biochemical processes, and molecular mechanisms. This paper reviewed the regulatory effects of UV-B radiation on plant morphology (e.g., inhibition of stem elongation, reduction in leaf area, and alteration of root-to-shoot ratio), as well as its direct or indirect damage to cell membrane stability, osmotic regulation substances (e.g., soluble sugars, proline), antioxidant defense systems (enzyme activities such as SOD, CAT, APX, and non-enzymatic antioxidants), and photosynthetic systems. Plants enhance their adaptability to UV-B stress through molecular mechanisms such as synthesizing secondary metabolites like flavonoids and anthocyanins, activating the UVR8-mediated signaling pathway, and activating hormone regulation and secondary metabolic genes. Furthermore, combined stress from UV-B and other environmental factors (e.g., temperature, drought, heavy metals) often exhibits synergistic or antagonistic effects, with complex mechanisms varying across species. Current research primarily focuses on crops and herbaceous plants under controlled experimental conditions. Future studies should integrate multi-omics technologies and long-term field observations to deeply unravel the molecular networks and ecological adaptability of plants in response to UV-B radiation, providing insights for stress-resistant breeding and ecological restoration.

The effects of deep fertilization on soil nutrients, plant nutrient uptake, plant growth and development, crop yield and quality were reviewed. Proper deep application of nitrogen fertilizer, phosphorus fertilizer, compound fertilizer, and organic fertilizer can all increase soil nutrient content. For example, deep application of nitrogen fertilizer (10-25 cm) can reduce nitrogen leaching and volatilization losses in soil; as the depth of compound fertilizer application increases, the ability of nitrate nitrogen in the soil to move downward increases. Proper deep fertilization enhanced nutrient absorption efficiency in crops. Fertilization in appropriate soil layers can promote the growth and development of crops, increases chlorophyll content in leaves, improves photosynthetic characteristics. Appropriate deep fertilization aligns the active root zones with nutrient supply areas, and improves fertilizer utilization efficiency. The impact of deep fertilization on yield and quality varies among crops, but proper deep fertilization generally enhances both. This study provides a reference for determining optimal deep fertilizations for different crops and exploring the benefits of yield increase with reduced fertilizer input.

Low temperature is one of the major environmental stress factors affecting plants, exerting significant influence on photosynthetic capacity and thereby hindering plant growth and development. The impact of low temperature stress on the photosynthetic mechanisms in plant leaves was summarized, focusing on changes in cellular anatomical structure, cell membrane permeability, osmoregulatory substances, and photosynthetic carbon assimilation. In terms of cellular anatomical structure, low temperature stress may disrupt the palisade/spongy tissue ratio in mesophyll cells and damage chloroplast ultrastructure. Regarding cell membrane permeability, low temperature stress induces electrolyte leakage, along with the accumulation of malondialdehyde and reactive oxygen species, leading to membrane lipid peroxidation. Plants counteract this by enhancing the activity of antioxidant enzymes such as superoxide dismutase (SOD) to maintain ROS homeostasis. Concerning osmoregulatory substances, low temperature stress triggers the dynamic accumulation of proline, soluble sugars, and proteins to sustain photosynthetic performance. In photosynthetic carbon assimilation, low temperature stress reduces chlorophyll content and the activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), altering key photosynthetic parameters such as net photosynthetic rate (Pn) and intercellular CO₂ concentration (Ci). Phosphoenolpyruvate carboxylase (PEPC) compensates for the decline in Rubisco activity by fixing low-concentration CO₂, thereby mitigating photosynthetic losses. In conclusion, this article provides a reference for analyzing the mechanism of plants’ response to low temperatures and improving the photosynthetic performance of plant leaves under low temperature stress conditions.

The practice demonstrates that combining animation IP with local characteristic industries not only drives youthful brand dissemination but also establishes a “cultural empowerment + industrial revitalization” dual-driven model, offering a replicable example for the sustainable development of rural specialty industries.

To evaluate the nutritional value of distillers dried grains with solubles (DDGS) derived from various raw materials, 30 DDGS samples were classified into 5 groups based on their raw material sources and crude protein content: rice DDGS, corn DDGS (Ⅰ), corn DDGS (Ⅱ), low-proportion cassava DDGS (CP > 18%), and high-proportion cassava DDGS (CP < 18%). The nutritional composition and predicted energy values were compared among these groups. Additionally, 5 representative DDGS samples were selected for further analysis of their gross energy, enzyme hydrolysate gross energy (EHGE), and digestibility determined by simulated digestion method.The results demonstrated that as the cassava substitution ratio increased, the crude protein and crude fat content of cassava DDGS gradually decreased, while crude fiber and crude ash content increased. Furthermore, model-predicted energy analysis revealed a significant decline in energy value with higher cassava substitution ratios, indicating poorer quality. Simulated digestion experiments confirmed that the energy value and digestibility of cassava DDGS decreased as the cassava substitution ratio rose.In conclusion, low-proportion cassava DDGS, with its high crude protein content and superior digestibility, is suitable as a quality protein source. Conversely, high-proportion cassava DDGS, characterized by elevated crude fiber and crude ash content, is less suitable for monogastric animals due to reduced nutrient utilization but can serve as a cost-effective roughage for ruminants.

Gray mold is a common disease in strawberry production, which can reduce the yield and quality of strawberry and cause certain economic losses. The pathogen and symptoms of strawberry gray mold, the infection cycle of the disease, the main factors influencing its occurrence, and comprehensive control measures were elaborated. There are many types of pathogens causing strawberry gray mold, mainly including Botrytis cinerea, B. caroliniana, and B. sinoviticola, etc. The main damage is to the fruit, initially showing water-soaked spots, and later expanding into gray-brown soft rot spots covered with mold; infected flower organs, leaves, and petioles show browning, rotting, and mold. The pathogen mainly overwinters in the form of conidia, mycelium, or sclerotia in diseased residues and soil, and spreads through air currents, water vapor, or agricultural operations, infecting plants through wounds or natural openings, and repeatedly reinfecting in a humid environment. The main factors influencing the occurrence of this disease include variety resistance, fruit maturity and whether it is damaged, the amount of bacteria carried by various plant organs, environmental conditions (temperature, humidity, the amount of spores in the air), and cultivation and management measures (close planting, poor ventilation, excessive nitrogen fertilizer application, and continuous cropping). In production, it is recommended to adopt comprehensive control measures including agricultural control measures such as selecting disease-resistant varieties and high ridge mulching cultivation, ecological control measures such as high-temperature fumigation, biological control measures such as applying antagonistic bacteria (such as Bacillus subtilis and Fusarium lateritium Pa2) and plant-derived agents (eugenol, carvacrol), and chemical control measures such as alternating use of low-toxic and highly effective fungicides such as procymidone and boscalid to effectively control the occurrence of strawberry gray mold. In the future, systematic research needs to be conducted in areas such as resistance monitoring systems, development of environmentally friendly fungicides, and disease monitoring and early warning systems to provide references for the control and in-depth study of this disease.

Based on a literature review, this paper synthesizes the mechanisms underlying the detachment of the mattic epipedon during the degradation of alpine meadows on the Qinghai-Tibet Plateau, discusses its ecological functions, and highlights that restoring the mattic epipedon is crucial for rehabilitating degraded grasslands. The mattic epipedon in alpine meadows of the Qinghai-Tibet Plateau is a unique surface soil layer composed of living/dead roots and humus, playing essential ecological roles in water conservation, carbon sequestration, nutrient cycling, and maintaining ecosystem stability. The detachment of the mattic epipedon is driven by multiple factors, including climate warming and drying, freeze-thaw cycles, grazing pressure, rodent disturbances, and human activities, manifesting as a degradation sequence from normal development, thickening, collapse, to complete detachment. The rupture of the mattic epipedon leads to deterioration of soil physicochemical properties, reduced microbial activity, and vegetation retrogressive succession, exacerbating the formation of “black soil patches”. Future research should focus on the response of the mattic epipedon to climate change, its role in carbon and nitrogen cycling, and restoration techniques to provide a scientific basis for the ecological rehabilitation of alpine grasslands.

Abiotic stresses such as light, drought, heavy metals and salinity are important environmental factors affecting the growth and development of plants. As a natural herbaceous plant, the growth and development of Mentha canadensis can also be affected by abiotic stresses. The effects of abiotic stresses such as light, drought and heavy metals on the germination of Mentha canadensis seeds and the growth of seedlings were reviewed. Blue light significantly promotes the growth of mint stems, while red and blue light can promote the growth of its roots. In a weakened environment, the root system grows slowly, the photosynthetic rate decreases, and the accumulation of organic matter reduces. Under drought stress, the photosynthesis of Mentha canadensis is inhibited, and the integrity of its biofilm structure is affected, which is not conducive to the improvement of its yield and quality. Heavy metals chromium (Cr), lead (Pb), and cadmium (Cd) all show the characteristics of promoting the growth of Mentha canadensis at low concentrations and inhibiting it at high concentrations. Moreover, with the increase of the treatment concentration, their physiological activities are affected to varying degrees. Salt and alkali can affect the seed germination of this plant and the growth of the embryo shoot and embryo root. Other factors such as CO₂ concentration, moisture content and ambient temperature can all have an impact on the growth of Mentha canadensis. This article provides references for exploring the mechanism of Mentha canadensis’s response to abiotic stress.

Native chicken is loved by consumers because of its fresh meat and rich nutritional value. The breeding technology of native chicken in Huangshan of Anhui Province from the aspects of chicken farm construction, variety selection, brooding and breeding management were introduced, and the breeding benefits in actual production were analyzed, and the corresponding measures were proposed. In the process of chicken breeding, the chicken farm should choose a higher terrain, ensure convenient transportation, stay away from residential areas, and ensure sufficient water, etc., it is appropriate to choose an adult weight of about 2 kg and a long tibial variety. In brooding stage, brooding rooms should be prepared in advance, and related facilities should be configured according to the number of brooding and breeding scale. In the process of brooding, the temperature and light should be controlled, the food and drink should be started timely, and the work of environmental management, feed transition and immunization should be done well. In terms of breeding management, when the body weight of chicks grows to about 0.5 kg, they are transferred to the adult chicken house for stocking. After the transfer, the activity of chickens and egg production rate are increased by adding perches and building egg boxes in the chicken house. In practice, through the above technical measures, the economic benefits are higher; however, in actual production, it is necessary to further strengthen management from the aspects of epidemic prevention and disinfection, market conditions, emergency skills, etc., to improve its economic benefits. This paper provides references for native chicken breeding in relevant areas.

Based on the occurrence and damage of the main rice diseases and insect pests, the comprehensive control technologies, including agricultural, biological, physical and chemical prevention and control were discussed. The primary diseases included rice blast (which infected leaves, nodes, and panicles), sheath blight (which infected basal leaf sheaths), and false smut (a panicle disease). The major pests included rice planthopper (which sucked sap), the rice leaf roller (which damaged leaves by rolling), and rice stem borers (which bored into stems). The integrated control was centered on the ecosystem and combined agricultural, biological, physical, and chemical technologies. Agricultural control involved selecting resistant varieties and implementing scientific field management; biological control generally utilized natural enemies and integrated crop-aquaculture systems; physical control often employed measures such as trapping and barrier methods; chemical control was focused on reducing application quantities and increasing efficiency by selecting low-toxicity agents. By comprehensively applying these control technologies, precise prediction and green management were achieved, which protected rice yield and quality and promoted sustainable agricultural development.

based on the climatic conditions of Zhou Rui Town, Dabu County, Meizhou City, Guangdong Province, high yield cultivation and postharvest preservation techniques for loquats were analyzed. The study area features a mild four-season climate with concurrent rainfall and heat, long summers, and short winters, making it highly suitable for cultivation. The high yield cultivation involves selecting deep, loose, well-drained soil for planting, with optimal timing in February (before spring bud emergence), early summer, or autumn. Key practices include pit expansion and soil improvement for young trees, balanced application of compound and organic fertilizers, controlled irrigation, timely fertilization to promote growth, and winter-spring pruning and fruit thinning for mature trees. During flowering and fruiting stages, measures such as flower stimulation, thinning, and fruit bagging are implemented. Major diseases and pests including leaf spot, anthracnose, loquat psyllid, and oriental fruit moth， are managed through preventive, integrated green control strategies. Postharvest protocols emphasize harvesting during dew-free mornings, evenings, or cloudy days, followed by rigorous sorting to remove damaged or diseased fruit before grading, packaging, and cold-chain transport. Preservation employs low-temperature storage, 1-methylcyclopropene treatment, and controlled atmosphere storage to extend shelf life. The research and development of deep-processed loquat products should be further expanded to increase their added value. This article provides a reference for the high yield cultivation and storage of loquat in the relevant areas.

The termite species infestation in water conservancy projects and their harmfulness were analyzed, the causes of termite infestation in water conservancy projects were explored, and the prevention and control strategies were proposed. In water conservancy projects, termite species are mainly distributed in Odontotermers and Macrotermers. The main species are Odontotermes formosanus, Macrotermes barneyi and Odontotermers hainanensis. Damage by termites may lead to leakage, piping and other dangerous situations, affecting the normal operation of facilities. The main reasons for termite infestation in water conservancy projects include suitable environmental conditions, construction-related residual issues, migration of adjacent termite source areas and inadequate daily management. Based on this, termite control strategies for water conservancy projects were proposed, including strengthen the maintenance of the surrounding environment, reduce the waterlogging area, trim and clear weeds on the embankment to destroy the living environment of termites, and plant termite-repellent plants. Enhance the engineering design and construction standards, and carry out comprehensive inspection and control of termites in the surrounding areas during the early stages of construction; in the process of dam filling, ensure that the compaction level of soil reaches the standard, reduce the porosity and weak parts; set up physical or chemical barriers during construction to prevent termite invasion.

To investigate the effects of the plant growth regulator Iron Chlorine e6 on rice growth, an experiment was conducted using the rice variety Ningxiangjing 9. The following treatments were applied: seed dressing with 0.02% Iron Chlorine e6 (A1, 22.5 g/hm²; A2, 45.0 g/hm²; A3, 67.5 g/hm²; A4, 90.0 g/hm²; CK, clear water control); foliar spraying at the jointing stage (B1, 22.5 g/hm²; B2, 45.0 g/hm²; B3, 67.5 g/hm²; B4, 90.0 g/hm²; CK, clear water control); foliar spraying at the booting stage (C1, 22.5 g/hm²; C2, 45.0 g/hm²; C3, 67.5 g/hm²; C4, 90.0 g/hm²; CK, clear water control). The traits, yield, and safety of rice plants under different treatments were determined. The results showed that foliar spraying of 0.02% Iron Chlorine e6 soluble powder increased panicle length and plant height, while seed dressing effectively thickened the basal internodes and enhanced lodging resistance. Both methods, at application rates of 45.0-90.0 g/hm², prevented lodging. Both seed dressing and foliar spraying of Iron Chlorine e6 increased the hundred-grain weight, seed setting rate, and yield of rice, with yield increases ranging from 2.14% to 11.95%. The C4 treatment achieved the highest yield (11 303.55 kg/hm²). All treatments were safe for rice growth. Considering economic benefits, it is recommended to apply 0.02% Iron Chlorine e6 at 67.5 g/hm² during the booting stage to improve rice yield.

To compare the historical evolution, medicinal effects and chemical components of jujube and Ziziphi Spinosae Semen, the authentic evolution, efficacy verification and active components of two medicinal materials were analyzed. The key components in the pulp and seeds of the two were identified by thin-layer chromatography (TLC), and the contents of saponin B and spinosin in Ziziphi Spinosae Semen were determined by high performance liquid chromatography (HPLC). Herbal research showed that jujube was mainly produced in Shandong and Shanxi provinces, while Ziziphi Spinosae Semen was mainly produced in the North China Plain and other northern regions. Both contain active components such as flavonoids and triterpenoids, but the content of hypnotic components (such as spinosin and saponin B) in Ziziphi Spinosae Semen was higher after stir-frying. TLC and HPLC showed that both the pulp of jujube and Ziziphi Spinosae Semen contained oleanolic acid and betulinic acid, while the seed of Ziziphi Spinosae Semen only contained betulinic acid, and neither of the two was detected in the seed of jujube. The content of saponin B in Ziziphi Spinosae Semen was determined by HPLC to be 0.021 7 mg/g, and that of spinosin was 0.072 6 mg/g, which might be related to the variety or harvest period. The above results indicated that the flesh components of jujube and Ziziphi Spinosae Semen were similar, but the kernels were significantly different. The medicinal parts of the two cannot be replaced. Ziziphi Spinosae Semen need to be stir-fried to increase efficiency, and their pulp can be developed into food (such as vinegar, pastries) to improve utilization.
