塑料薄膜地面覆盖栽培,是近年来新兴的农业技术之一,已在许多作物上应用。为了探索冬、春小麦实行薄膜地面覆盖栽培的效果,1980～1981年进行了小麦薄膜地面覆盖栽培的试验研究。一、试验情况薄膜为沈阳市红旗塑料厂生产的,宽1.2米,厚0.015毫米;小麦为当地推广的东方红三号和辽春八号;试验地为沙质壤土,肥力中等;采用床播栽培;于播种同时一次施足化肥。1.冬小麦地膜覆盖分三期播种(9月26日、10月3日、10月10日),以第一期不盖膜为对照。顺序排列,重复四次。小区面积8.8
Plastic film ground cover cultivation, one of the emerging agricultural technologies in recent years, has been applied to many crops. In order to explore the winter and spring wheat film mulching cultivation effect, from 1980 to 1981 the wheat film ground cover cultivation experiments. First, the test conditions The film is Shenyang Hongqi Plastic Factory production, 1.2 meters wide and 0.015 millimeters thick; wheat is the local promotion of Dongfanghong III and Liaochun 8; test for sandy loam, medium fertility; bed broadcast Cultivation; at the same time sowing sufficient fertilizer. 1. Winter wheat mulching covers in three stages (Sept. 26, Oct. 3, Oct. 10), with the first phase of non-membrane as control. Order, repeat four times. Cell size 8.8
