Dietary polyphenols are widely found in fruits, tea, and other foods, and have various active functions such as antioxidant and anti-inflammatory.In this paper, the research progress of the interaction between dietary polyphenols and intestinal microbiota was analyzed from 3 aspects: the effect of dietary polyphenols on the host, the relationship between intestinal microbiota and host health, and the interaction mechanism between dietary polyphenols and intestinal microbiota. In terms of host effects, dietary polyphenols have positive effects on host cardiovascular diseases due to their antibacterial and anti-inflammatory properties. Intestinal microbiota regulate immunity and other functions by producing metabolites such as propionic acid and aromatic amino acids, thereby enhancing the immune function of the host. In terms of the interaction between the two, the intake of dietary polyphenols can affect the types and quantities of intestinal microorganisms, regulate the balance of microbial communities, increase the proportion of probiotics, and reduce the number of harmful bacteria. The gut microbiota modifies the intake of dietary polyphenols, regulates their metabolism and absorption, and thus plays a role in the host. This study provides a reference for further exploring the role of dietary polyphenols in preventing and improving intestinal health.

Wheat basal rot is a disease that has occurred in wheat fields in recent years, particularly in corn-wheat continuous cropping fields, where it has shown a trend of increasing severity, causing a reduction in this plant yield and quality to some extent. To understand the occurrence characteristics of this disease and effectively control its spread and minimize damage, based on the wheat production practice in Lingbi County, Anhui Province, the occurrence, damage symptoms, disease characteristics, and influencing factors of this disease rot were analyzed through years of field investigations and a review of relevant literature. On this basis, the health cultivation as the basis were proposed, including the selection of resistant varieties, crop rotation, appropriate deep plowing, removal of straw from the field, precision seeding, and balanced fertilization. Additionally, seed treatment with chemicals during the wheat sowing period, the use of highly effective and low-toxicity pesticides for green control during the regreening stage, and an integrated control technology combining “one spray for three preventions” during the heading stage to manage wheat basal rot were recommended.

The species, distribution and geographical flora of the Geometrinae in Shandong Province were analyzed by means of literature statistics, and the morphological characteristics of each species were described. The results showed that, there were 12 genera and 13 species of Geometridae insects in the area. 13 species had a wide geographical distribution, the most widely distributed of which were Geometra and Comibaena insects. The fauna analysis showed that the distribution of 13 species in Central China (13 species), North China (12 species) and Southwest China (11 species) were greater, and the number of species in Central China was the highest, while the number of species in Mengxin area (5 species) and Qinghai-Tibet area (3 species) were relatively small. The results provide references for the prevention and control of these insects, maintaining the health of agriculture and forestry, and protecting the species diversity of the Geometrinae.
