少耕、免耕具有较高的经济效益;是减轻风蚀、水蚀危害的有效措施,储水保墒效果显著,并能促进土壤有机质的积累.根据少耕、免耕在生产上存在的问题,今后应开展防除杂草和地下害虫的研究,同时研究适应少耕、免耕制的栽培技术、施肥技术及少耕、免耕与地面覆盖相结合的效果等等. Less tillage and no tillage have higher economic benefits; it is an effective measure to reduce the risk of wind erosion and water erosion, and the effect of storing water and soil moisture is remarkable and can promote the accumulation of soil organic matter. According to the problems of less tillage and no tillage in production, Research should be carried out to control weeds and underground pests, and to study the effects of tillage and no-tillage cultivation techniques, fertilization techniques and the combination of no-tillage and ground cover.
