随着耕作制度的改革,复种指数的提高,晚播小麦的面积逐渐扩大,而小麦地膜覆盖是解决晚播小麦冬前积温不足的突破性栽培技术措施。为了提高晚播小麦地膜覆盖的增产效果和探讨提高经济效益的方法,我们于1984年10月布置了小麦地膜覆盖不同揭膜期试验。一、试验方法试验设置在三门峡市会兴乡山前村,试验田土质为壤土,肥力中等,无水浇条件,前茬绿豆与夏谷间作,绿豆亩产七十五公斤,谷子亩产一百五十公斤。前茬作
With the reform of tillage system and the improvement of multiple cropping index, the area of late sowing wheat gradually expanded, while the wheat mulching was a breakthrough cultivation technical measure to solve the problem of late accumulated sowing temperature of late sowing wheat. In order to improve the yield-increasing effect of late-sowing wheat film mulching and to explore ways to improve economic efficiency, we arranged the different mulching test of wheat mulching in October 1984. First, the test method Set in Sanmingxia Sanxing Xiaoshan village, the experimental soil is loam soil, medium fertility, no water conditions, the former crop mung beans and summer valley intercropping mung bean mu 75 kilograms, millet mu produce 100 Fifty kilos. Former crop
