绿肥油菜在中国农业生产中的应用研究进展OA

Green manure rape(Brassica napus L.)serves as a clean organic fertilizer source.It plays a vital role in improving soil fer-tility,ameliorating soil structure and optimizing soil biological properties,and can strongly support the endogenous promotion of soil health and the implementation of the strategy of green agricultural development.The decomposition characteristics and nutrient release patterns of returned green manure rape straw were systematically analyzed,and the regulatory effects of key factors including returning methods,soil environment,nitrogen fertilizer application and decomposer inoculants on its decomposition rate and dynamic nutrient release were clarified.The application modes and ecological effects of green manure rape in five typical agricultural scenarios in Chi-na,namely paddy fields,dry farmlands,orchards and tea gardens,saline-alkali lands,and heavy metal contaminated farmlands,were comprehensively summarized.Meanwhile,the prospects for the research and application of green manure rape were proposed from three aspects:the analysis of microbial driving mechanisms,multi-objective collaborative scenario application,and the construc-tion of popularization and service systems,aiming to provide theoretical support and technical reference for the high-quality and green development of agriculture in China.
