甘肃省中东部旱作农业区处在黄土高原丘陵沟壑区,降水量极度匮乏,由于传统精耕细作等原因,导致水土流失严重,耕地边沿地带土壤沙化面积不断扩大,严重影响了农业的可持续发展。针对这种情况,农技推广人员结合近年来在本省大面积推广的玉米全膜双垄沟播技术,提出了全膜双垄沟播玉米后茬免耕栽培技术。该技术是在前茬全膜双 The dry farming areas in the central and eastern Gansu Province are in the hilly and gully regions of the Loess Plateau, where the precipitation is extremely scarce. Due to the traditional intensive cultivation and other causes, soil erosion is serious, and the area of ​​sandy desertification on the edge of cultivated land continues to expand, seriously affecting the sustainable development of agriculture. In response to this situation, agricultural extension workers combined with the large-area popularization of maize in recent years, the whole film double ridge furrow sowing technology, put forward the film double-ridge furrow sowing maize after crop cultivation techniques. The technology is double the whole film in the previous crop
