摘要
为筛选出适合巩留县玉米田的降解地膜类型,使用6种全生物可降解地膜和1种常规PE膜,在大田里进行试验,研究降解地膜对土壤温度及作物产量的影响。结果表明:5号地膜和6号地膜在玉米产量方面与普通PE膜无差异,其它降解地膜显著减产;大田土壤温度与玉米产量呈正相关关系。
In order to select out type of degradable mulching film suitable for maize fields of Gongliu county,taking six kinds of biodegradable plastic film and a conventional PE film had,the effect on soil temperature and maize yield was studied.The results showed that the treatment 5and 6no difference in maize yield with the ordinary PE film,other degradable mulch film had significantly reduction;soil temperature and yield of maize were positively correlaed.
