水土保持耕作措施是指在坡耕地上采取的等高耕作,垄沟种植,如山地水平沟,套犁沟播、垅作区田、倒壕换垅、平播起垅、丰产沟等办法。它可改变小地形,增加地面糙率,使之拦蓄雨水,加强土壤水分入渗,减少水土流失。从而达到保持水土,增产粮食的目的。延安地区水保所从1980年开始,在延安市枣园公社上砭沟大队,结合流域治理,进行了水土保持耕作法的试验、示范,并进行了推广。试验和生产实践证明,水土保持耕作法具有蓄水、
Soil and water conservation tillage measures refer to contour tillage and furrow planting adopted on sloping farmland, such as horizontal furrows in mountainous areas, sowing furrows for broadcasting, planting fields and fields, changing trenches and changing troughs, spreading sowing and harvesting ditches. It can change the small terrain, increase the roughness of the ground, make it intercept rainwater, strengthen soil water infiltration and reduce soil erosion. So as to achieve the purpose of maintaining soil and water and increasing grain output.
