绿肥对主作物农艺性状、病虫草害及土壤的影响

Research progress on the effects of green manure on the growth,disease,pests,weeds,and soil of main crops

绿肥在用地养地、保障粮食安全和改善生态环境等方面具有重要的作用。为了探究绿肥对主作物系统的影响,本文查阅了2015年以来主作物耦合绿肥的相关文献,归纳了绿肥对主作物农艺性状、病虫草害的防控以及对土壤理化性质等的影响。总体上,绿肥可有效改善土壤理化性质,促进养分转化,提高主作物对养分、水分的利用效率;影响主作物生理生化,促进主作物生长,提高主作物产量和品质,有效降低主作物病虫害的发生和危害,是实现绿色循环农业的重要途径。本文根据研究现状,对未来的研究方向进行了展望,提出加强对绿肥种植经济效益的评估和绿肥-主作物一体化病虫害防控方面的研究,进一步强化绿肥产品的推出与销售。

Green manure plays an important role in cultivating land,ensuring food security,and improving ecological environments.To explore the influence of green manure on main crop systems,this paper reviewed the relevant literature concerning the coupling of green manure with main crops since 2015 and summarized the influence of green manure on the agronomic traits of these main crops.In general,green manure can effectively improve soil physical and chemical properties,promote nutrient transformation,and improve the nutrient and water use efficiency of main crops.Using green manure important way to realize green circular agriculture by affecting the physiology and biochemistry,promoting the growth,improving the yield and quality,and effectively reducing the occurrence and harm of diseases and pests on main crops.Furthermore,according to the current research situation,we provided future research directions,evaluated the economic benefits of green manure cultivation,proposed research for the integrated prevention and control of green manure and main crops,and strengthened the case for introducing and selling green manure products.
