我省冬春两季,雨雪稀少干旱风大,寒流频繁降温剧烈,因此冬小麦在冬春两季生育期间经常处于旱冻交加的严酷生态条件之中。这是造成我省冬小麦产量低而不稳的主要原因之一。为了探索冬小麦低产变高产,高产更高产,解决冬小麦的防寒抗冻和促使三类麦苗升级赶队,我们应用地膜覆盖栽培技术,改善农田小气候,促进冬小麦早熟、高产并做到一膜两用,提高其经济效益。试验从1981年至1984年,并与省农牧厅农业局协作布点示范79.85亩,推广面积为二千余
Winter and spring in our province two seasons, rain and snow is scarce Arid wind, cold frequent severe cooling, so winter wheat growing season is often in the harsh ecological conditions of frozen intercourse. This is one of the main reasons for the low and unstable winter wheat production in our province. In order to explore the low yield and high yield of winter wheat, high yield and high yield, to solve the winter cold and frost resistance and promote the three types of wheat seedlings escalating the queue, we apply mulching cultivation techniques to improve the farmland microclimate and promote winter wheat, Improve their economic efficiency. The experiment from 1981 to 1984, and the provincial Department of Agriculture and Animal Husbandry Bureau of Agriculture distributed demonstration demonstration 79.85 acres, to promote an area of more than 2000
