针对高标准农田建设宜机化地块整理整治后的土壤培肥熟化问题,及近年来因过度施用化肥而导致的土壤酸化、板结等问题,重庆市通过绿肥种植试验示范,结合土壤环境保护和机械化生产技术,创新探索出了绿肥机械化轻简生产技术。其主要体现为2次机械化作业(抛撒和深松整地)完成传统生产方式中的6个作业环节(灭茬、旋耕、开沟、播种、施肥和盖种)。绿肥机械化轻简生产可减少化肥施用量,节约生产成本,保持和提高耕地质量,保护和改善生态环境,保证和提高农产品的产量及品质,促进农业的可持续发展。
In view of the problem of soil fertilization and ripening after the reorganization of high-standard farmland, and the acidification and compaction of soil caused by over-fertilization in recent years, Chongqing Municipality, through demonstration of green manure cultivation, combined with the protection of soil environment and Mechanization of production technology, innovation to explore the mechanized green light fertilizer production technology. Its main manifestation is that two mechanized operations (throwing and subsoiling) complete six operations (stubble removal, rotary tillage, ditching, seeding, fertilizing and capping) in the traditional mode of production. Green manure mechanization Simple production can reduce the application of chemical fertilizers, save production costs, maintain and improve the quality of arable land, protect and improve the ecological environment, ensure and improve the output and quality of agricultural products, and promote the sustainable development of agriculture.
