摘要
本文对国内外18种光解膜进行小区试验、筛选,以及试验筛选适合农艺要求的新疆5#膜进行大面积生产示范。结果表明:光解膜能降解为碎片;具有与普通膜相同的保温及增产效果,诱导期60天左右,较适合我省的气候特点。
In this paper, 18 kinds of photo-degradable films from home and abroad weretested and selected in field plots and conducted productive demonstration to Xinjang film NO.5 which is suitable to agronomic demand. The experiment results showed that photo degradable films can degrade into pieces. They had the same effect of heat-preservaton andyield increase compared to general vinylon film. Through the experiment we think that thefissure-induced period around 60 days is suitable to climatic features of Heilongjiangprovince.
