新疆是我国最大的干旱区,在一定意义上说,没有灌溉就没有农业.五十年代,新疆种麦主要是采用平播小畦灌;六十年代,新疆推广了农六师天山九场和头屯河农场等单位创造的小麦顺地势开尖底沟沟植沟灌法;七十年代,由于开尖底沟播种不适于机械追肥,平播又取代了沟播.但是,生产实践证明,小麦沟植沟灌利于积雪,越冬保苗好,灌水劳动强度小,灌水质量好,省水增产,所以不应被弃掉,关键在于解决好沟播机具问题.为此,我们于1980年秋,改装播 Xinjiang is China’s largest arid zone, and in a certain sense, there is no agriculture without irrigation. In the 1950s, Xinjiang’s wheat growing mainly consisted of sowing the sowing crops. In the 1960s, Xinjiang promoted the sixth division of the Tianshan Mountains In the 1970s, seeding was not suitable for mechanical top dressing due to open-bottom ditch, and flat-screen replaces ditching, but production practices have proved that wheat ditches The key point is to solve the problem of channeling and sowing machines. Therefore, in the autumn of 1980, we modified and sowed the sowing materials
