不同类型地膜在花生种植中的效应分析

摘要

本试验以含 mLLDPE 地膜及生物可降解两类地膜为试材,研究了不同类型地膜覆盖种植花生产生的效应及花生生育期后地膜的回收效率和降解率。结果表明,0.006mm 厚含30%mLLDPE的地膜覆盖种植能显著提高花生产量,且易于回收。而生物可降解地膜均具有良好的降解性,能避免地膜回收的繁重工作,但在提高花生产量方面存在不足。%Field experiment was conducted with two types of mulch films, mLLDPE and biode-gradable film, to examine their different effects on peanut cultivation and the recovery efficiency and degradation rate of the films after a period of peanut growth.The results showed that, mulching cultiva-tion with the 0.006mm film containing 30% mLLDPE can significantly improve the yield, and it was easy to recycle.The biodegradable plastic film has good biodegradability and its application can prevent people from the hard recycling work.But further study are required on its unperfect effect of peanut yields improvement.
