一项使我国小麦亩产增幅超过30％的重大科技成果“小麦全生育期地膜覆盖穴播栽培技术”，目前受到我国农业专家的高度评价，被称之为“农业技术革命”。为寻找提高小麦亩产的突破性技术，我国各地农业科技工作者进行了多年的试验研究，终于在90年代由甘肃省农科院粮作所研究出? A major scientific and technological achievement that has increased the output of wheat in our country by more than 30% per mu is “the mulching cultivation by plastic film mulching during the whole growing period of wheat”, which is highly praised by Chinese agricultural experts and is called “the agricultural technological revolution.” In search of a breakthrough technology to improve the yield of wheat, agricultural scientists from all over China have conducted many years of experimental research and finally developed it by the Gansu Academy of Agricultural Sciences in the 1990s.
