利用地膜,冬季盖小麦,早春起膜再盖棉花或其它作物,称“一膜两用”。经三年试验示范证明,不仅小麦高产稳产,而且双季增产;同时提高了地膜利用率,降低了盖膜成本,增加了经济效益。一、增产效果和经济效益(一)地膜覆盖小麦,能大幅度增产据我县三年10块地138.3亩覆盖麦田产量统计,覆盖的较对照(不盖)亩增产200—300斤,增产幅度20—40%。如县农技中心,两年覆盖试验亩产都过千斤,最高达1,100斤。1983年小麦生长发育后期遇到灾害天气,影
Use of plastic film, cover wheat in winter, early spring and then covered with cotton or other crops, known as “a dual-use film.” After three years of demonstration experiments, not only the high and stable yield of wheat, but also increased production in double seasons; at the same time improve the utilization of the film, reducing the cost of the cover film, increased economic benefits. First, the stimulation effect and economic benefits (A) covering wheat, plastic mulching can significantly increase According to the county three years 10 138.3 acres of land covering wheat yield statistics, covering more than the control (not cover) mu 200-300 pounds increase in yield 20-40%. If the county agricultural technology center, covering two acres of test yield over a thousand pounds, up to 1,100 pounds. 1983 wheat growth and development late encountered disaster weather, shadow
