“雨养农业”是在在水资源日益紧缺、土壤肥力下降的情况下提出来的。它是“节水型农业”的重要战略措施之一,是实现丰收的重要内容。所谓“雨养农业”,即在雨季把麦秸、麦糠直接还田,均匀地铺在大秋作物的行间(厚5—10厘米),这样能把天然降雨贮在土壤中,并把麦秸逐步变成有机肥料,使其不断供应作物生长发育的需要。1986年 “Raining agriculture” was put forward under the condition of increasingly scarce water resources and declining soil fertility. It is one of the important strategic measures for “water-saving agriculture” and an important part of achieving harvest. The so-called “rain-fed agriculture”, that is, in the rainy season wheat straw, wheat bran directly back to the field, evenly spread between rows of large autumn crops (5-10 cm thick), so that the natural rainfall stored in the soil, and wheat straw step by step Into organic fertilizer, making it the continuous supply of crop growth and development needs. 1986
