摘要: 绿肥植物体营养成分高,翻压绿肥作物有利于改善土壤质量,培育优良耕作的土壤,改善农作物品质,并对改良土壤理化性质、提高肥料利用率及促进作物生长有一定的协同作用。绿肥是用新鲜的绿色植物本体作为肥料基础,直接或间接地将植物体鲜样翻压到土壤中,待其腐朽分解后释放养分到土壤中代替肥料供主作物生长,或是通过绿肥作物与主作物的间套轮作,为主作物提供养分,起到促进主作物生长发育,改善土壤理化性状等作用,它是一种天然绿色无污染肥料。本文分析了绿肥作物的特性,探讨了绿肥还田对土壤理化性质和肥料利用率的影响,并展望了今后绿肥的应用前景,旨在为绿肥更好地应用于作物生产提供参考。

Abstract: Green manure plants have high nutrient content. Overturning green manure crops is conducive to improving soil quality, cultivating good farming soil, and improving crop quality. It also has certain synergistic effects on improving soil physical and chemical properties, improving fertilizer utilization, and promoting crop growth. With the fresh green plant body as a fertilizer base, green manure is a natural green pollution-free fertilizer formed by directly or indirectly compressing fresh samples of the plant body into the soil to release nutrients into the soil after its decay and decomposition instead of fertilizer for the growth of the main crop, or by intercropping the green fertilizer crop with the main crop, to provide nutrients for the main crops, promote the growth and development of the main crops, and and improve the physical and chemical properties of the soil. In this paper, the characteristics of green manure crops were analyzed, and the effects of green manure crops on soil physical and chemical properties and fertilizer utilization rate were discussed. The future research directions and prospects of green manure were expected, indicating that green manure has great potential in agricultural development. The development potential is to provide reference for the research on the effects of green manure on crop production.

Key words: green manure, overturned field, fertilizer utilization, soil properties
