本文主要论述了免耕播种机械化技术的经济、社会、生态效益,该项技术的实施,可提高土壤含水率6%～9%,减少农田风蚀和扬沙50%～80%,提高土壤有机质含量0.04%～0.08%,减少坡地水蚀60%～80%,提高作物产量2%～10%,节约作业成本150元/hm2～375元/hm2,对防治风沙暴、改善农牧业生态环境、实现农牧业可持续发展有着重要的作用。 This paper mainly discusses the economic, social and ecological benefits of no-tillage sowing mechanization technology. The implementation of this technology can increase soil water content by 6% ~ 9%, reduce wind erosion and 50% ~ 80% 0.04% ~ 0.08%, reduce water erosion in sloping fields by 60% ~ 80%, increase crop yield by 2% ~ 10%, and save operating cost by 150 yuan / hm2 ~ 375 yuan / hm2, to prevent and control wind storms and improve the ecological environment of agriculture and animal husbandry Sustainable development of agriculture and animal husbandry has an important role.
