Green manure is an efficient and clean technology for substituting chemical fertilizers in farmland.It is the most effective means to cultivate healthy soil and curb farmland degradation,as well as the best material and technological guarantee for producing healthy agricultural products.In the new era with new requirements,it is necessary to strengthen the development planning of green manure,so as to promote the progress of green manure production and industrialization.By summarizing and refining the long-term work on green manure,large-scale joint research,literature review,the current situation,potential,institutional models,and key tasks of green manure development in China were analyzed.The results were listed as follow.(1)The production technology of green manure had continuously improved and developed.The new mechanism of green manure industrialization("green manure +")had achieved significant achievements.The scale of green manure production had steadily recovered,and the green manure plantation area in China reached 4.12 million hectares in 2022.(2)About 88%of the potential green manure area in our country had not been utilized.The total potential area of green manure in main agricultural regions and economic orchards was approximately 42.27 million hectares,with the potential areas for green manure in agricultural regions and economic orchards being 33.40 million hectares and 8.87 million hectares,respectively.(3)An overview of the green manure utilization technology model applicable in typical regions of agricultural fields,fruit and tea gardens,newly cultivated land,and marginal land in China was provided.(4)The key tasks for the recent development of green manure in China are to improve the level of seed industry guarantee for green manure,strengthen technological innovation and application,expand the path of national strategic services for green manure,promote the construction of green manure industrial paths,and innovate policies that guarantees green manure industry.By 2025,the production technology and application of green manure will be further improved,and the production area of green manure will be steadily increasing.The contribution of green manure to the quality of arable land and regional economy will significantly increase.In the context of the new era,it is necessary to meet the current needs and focus on leaving fertile land for the future.Promoting green manure production and industrialization should be regarded as an important means to comprehensively promote rural revitalization.
