蓄水丰产沟一般是在干旱缓坡地上沿等高线筑成有沟的水平耕作带,生土起垄,活土填沟,组成一个“生土垄”和“种植沟”,种植沟内覆膜种植,具有明显的蓄水保墒增温增产的作用。耕作带的规格可因地块田作物设置,种植玉米、马铃薯等稀植作物,一般为:带宽1.2米,生土垄、种植沟各占0.6米,生土垄高约0.3米,种植为内熟土层厚度约0.5米。穴播种植小麦等规格应根据所用地膜宽度而定,为保
Water harvesting ditches are generally horizontal tillage belts built along the contours of droughts on gentle arid slopes to raise soil and raise furrows to form a “raw soil ridge” and “planting ditch” Membrane planting, with obvious water warming effect of increasing yield. The specifications of the cultivation belt may be due to the setting of field crops in the field and the cultivation of rare crops such as corn and potato. Generally, the width of the cultivation is 1.2 meters and the planting ridge is 0.6 meters. The height of the furrow is about 0.3 meters and the planting is within Clad soil thickness of about 0.5 meters. Sowing planted wheat and other specifications should be based on the width of the film used to protect
