| 摘 要： | 为了减轻农田白色污染,加快可降解地膜的应用,采用模拟实验,比较了新开发的3种淀粉基可降解地膜对土壤温度和水分保持的效应及其对玉米成苗的影响。结果表明,覆膜处理的土壤5 cm温度明显高于无覆膜对照,土壤10 cm处温度无明显差异,降解膜B的保温性能与普通膜D相当;各覆膜处理的保水性能均高于无覆膜对照,出苗前和幼苗后期各覆膜处理差异不明显,幼苗中期,降解膜B的保水效果明显优于降解膜A、C;3种降解膜和普通地膜对玉米株高和叶面积的影响显著,而对干鲜重的影响差别不大。可降解地膜B可作为普通膜的替代产品投入应用。

| Abstract: | In order to enhance to reduce white pollution and speed up the application of biodegradable mulch films.A study was conducted to compare effects on temperature and moisture of soil and maize seeding to three kinds of starch-based degradable films with a pot experiment,using ordinary plastic film D and no mulching treatment CK as the controls.The results showed that soil temperature in 5 cm soil depth of mulching treatments were higher than that of no mulching treatment,but there were no obvious differences ... |
