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

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.
