冬小麦膜侧沟播是一项新的抗旱、增产栽培技术,1998年已在我县示范推广1.2万hm2,平均产量3150kg/hm2,比常规露地种植增产21%,具有十分显著的经济效益。为了进一步提高冬小麦膜侧沟播栽培技术的土地利用率和经济效益,我县进行了冬小麦膜侧沟播膜面套种蚕豆试验、示范,平均产冬小 Film-side sowing of winter wheat is a new drought-resistant and yield-increasing cultivation technique. In 1998, 12,000 hm2 was popularized in our county with an average output of 3150kg / hm2, an increase of 21% over that of conventional open-field cultivation, with significant economic benefits. In order to further improve the land utilization and economic efficiency of winter wheat film mulching cultivation techniques, my county conducted a film mulching on the membrane surface of winter wheat film broad bean test, demonstration, the average winter
