为了研究不同厚度地膜对玉米生产的影响及废旧地膜100%回收用时量和一次性揭膜残留量,筛选出适合甘肃省会宁县适用的新型地膜,提高废旧农膜回收利用率,以期为全县农膜的合理使用提供技术依据。试验结果表明:地膜厚度在一定程度上影响了土壤的温湿度,较厚地膜相对于较薄地膜来说,提高了作物的出苗率,对作物的生物学性状也有一定的改善,产量也有所提高。同时,从地膜回收再利用角度来看,地膜越厚,越有利于回收。
In order to study the impact of different thickness of plastic film on corn production and waste film 100% recovery time and the amount of disposable film uncovering, suitable for Gansu Province applicable screening of new type of plastic film to improve the recycling rate of waste plastic sheeting, with a view to all county farmers Membrane reasonable use to provide technical basis. The results showed that the film thickness affected the soil temperature and humidity to some extent. Compared with the thinner film, the thicker film increased the germination rate of the crop and also improved the biological characters of the crop, and the yield was also increased . At the same time, from the film recycling point of view, the thicker the film, the more conducive to recovery.
