两年来,我省花生地膜覆盖栽培取得了较好经济效果.为了进一步扩大地膜覆盖面积,下面谈谈有关栽培技术的几个问题.一、塑料薄膜的选择覆盖花生的地膜,需有利于花生果针的穿透,使之入土结果.但目前有些塑料工厂生产的地膜太厚,花生果针很难穿透,形成大量无效果针.据大连市农科所用大连产的不同厚度薄膜试验,厚0.01毫米膜,果针穿透率为43.3%,单株结果数为18.1个;厚0.02毫米膜,果针穿透率为25.5%,单株结果数为13.6个.
In the past two years, peanut mulching has achieved good economic results in our province .In order to further expand the mulching area, the following talk about several issues related to cultivation techniques.First, the choice of plastic film covering peanut mulch, peanut should be conducive to the fruit Needle penetration, so that the results into the soil.But some plastics factory production of plastic film is too thick, peanut fruit needle is difficult to penetrate, forming a large number of ineffective needle.According to Dalian Agricultural Science and Technology used in the production of different thickness of the film test, thick 0.01mm film, needle penetration rate of 43.3%, the number of single plant results was 18.1; 0.02 mm thick membrane, needle penetration rate of 25.5%, the number of single plant results of 13.6.
