Rice Variety ‘Jindao 12’: High-efficiency Cultivation Integration Technique
为了实现山西水稻生产中高产、优质、高效、生态、安全的目标,推动山西水稻产业的发展,该研究以‘晋稻12号’为试验材料,采用随机区组设计方法,比较分析了不同的施肥方案与水分管理方式对其农艺性状的影响。结果表明:不同栽插密度与追肥比例处理对水稻生育进程均影响不大,但对其产量性状有一定的影响,其中,追肥比例为A2时,其增产效果最佳;此外,追肥比例为A2,栽插密度与施肥量分别为D1、N3时,其增产效果最优;在栽插密度D1,施肥比例A2,施肥量N3的配比处理下,进一步优化了灌溉方式,集成的新模式与原栽培方式相比,其增产率可达17.9 %。综合以上试验结果,本研究总结提出了一套‘晋稻12’的高产高效栽培技术,其兼具节水、提质、增抗等优点,为深入开展水稻栽培技术方面的研究奠定了良好的基础。
To realize the target of high yield, fine quality, high efficiency, eco-friendly and safe rice production in Shanxi, and promote the development of rice industry, the authors selected ‘Jindao 12’ as the test material, analyzed the effects of different fertilization schemes and water management on its agronomic characters with the randomized blocks design. The results showed that different transplanting densities and ratios of topdressing had no significant effect on the growth process of rice, while they had certain effect on the yield trait. When the ratio of topdressing was A2, the yield increasing benefit was the best. In addition, the yield increasing effect was also the best when the ratio of topdressing, transplanting density, fertilization was A2, D1, N3, respectively. Under the treatment of transplanting density D1, ratio of topdressing A2 and fertilization N3, the irrigation method was further optimized and the new integrated mode could increase the yield by 17.9%. Based on the above experimental results, the study proposed a new cultivation mode of high-yield and high-efficiency for ‘Jindao 12’, which had the advantages of water saving, quality improving and resistance enhancing. This study could provide a foundation for further research on rice cultivation technique.

【目的】分析全球水稻生产现状及其制约水稻生产的主要因子,探讨提高水稻产量的主要途径。【方法】采用全球水稻生产资料定量分析水稻面积和单产变化及其对总产贡献,及制约水稻生产的主要因素。【结果】全球水稻生产自1961年至2006年,由于复种指数提高,面积增长32%,年均增长0.61%。单产提高1.21倍,年均增长1.82%,单产提高主要依靠矮杆品种和杂交稻及其配套栽培技术的推广,灌溉设施改善和化肥施用。总产增长1.92倍,年均增长2.46%。水稻总产增长中,由面积增长贡献27%,由单产提高贡献73%。20世纪60年代以来全球水稻面积年增长率呈现逐年下降趋势。近年来水稻单产的增长率逐年变小,20世纪80、90年代和2000年以来分别为2.58%、0.98%和1.16%。面积下降和单产增长率变小导致总产增长率下降,20世纪80、90年代和2000年以来总产年均增产率分别为2.73%、1.48%和0.88%。制约水稻生产的主要因子是,水稻生产技术对单产提高的贡献率下降,病虫草危害及自然灾害频繁,多熟制生产系统水稻单产下降,水稻生产效益低。【结论】提高水稻产量的主要技术对策是改良水稻品种和扩大杂交稻应用,在非洲推进非洲新水稻应用,推广水稻集成栽培技术弥合水稻产量差异,发展水稻机械化生产技术及政府加大对水稻生产的政策支持。 {{custom_citation.content}}

Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept. The occurrence of interference rests on the lack of which-way information and on the absence of decoherence mechanisms, which could scramble the wave fronts. Here, we report on the observation of two-center interference in the molecular-frame photoelectron momentum distribution upon ionization of the neon dimer by a strong laser field. Postselection of ions, which are measured in coincidence with electrons, allows choosing the symmetry of the residual ion, leading to observation of both, gerade and ungerade, types of interference.

BACKGROUND: The growth of halal food consumption worldwide has resulted in an increase in the request for halal authentication. DNA-based detection using powerful real-time polymerase chain reaction (PCR) technique has been shown to be highly specific and sensitive authentication tool. The efficient DNA extraction method in terms of quality and quantity is a backbone step to obtain successful real-time PCR assays. In this study, different DNA extraction methods using three lysis buffers were evaluated and developed to recommend a much more efficient method as well as achieve a successful detection using real-time PCR. RESULTS: The lysis buffer 2 (LB2) has been shown to be the best lysis buffer for DNA extraction from both raw and processed meat samples comparing to other lysis buffers tested. Hence, the LB2 has been found to be ideal to detect meat and porcine DNAs by real-time PCR using pairs of porcine specific primers and universal primers which amplified at 119 bp fragment and 93 bp fragment, respectively. This assay allows detection as low as 0.0001 ng of DNA. Higher efficiency and sensitivity of real-time PCR via a simplified DNA extraction method using LB2 have been observed, as well as a reproducible and high correlation coefficient (R(2) = 0.9979) based on the regression analysis of the standard curve have been obtained. CONCLUSION: This study has established a fast, simple, inexpensive and efficient DNA extraction method that is feasible for raw and processed meat products. This extraction technique allows an accurate DNA detection by real-time PCR and can also be implemented to assist the halal authentication of various meat-based products available in the market.
