摘要
为了筛选出适合尉犁县棉田的降解地膜类型,使用9种全生物可降解地膜和1种常规PE膜,在大田里进行试验,来研究降解地膜对棉花产量的影响。结果表明：处理2和处理3在棉花产量方面与普通PE膜无差异,其它降解地膜显著减产,减产幅度为1.38%~3.39%。各处理间产量的差异主要是受收获株数的影响。
In order to select out the type of degradable mulching film suitable for Yuli county cotton production,taking 9 kinds of biodegradable plastic film and a conventional PE film,experiment was conducted in the field,the effect of degradation film on cotton yield was studied.The results showed that treatment 2 and 3 in the cotton yield and ordinary PE film had no difference and other degradable mulch film reduced significantly,the production rate was 1.38%-3.39%.The difference of yield among treatments was mainly affected by the number of harvest.
