寒地半干旱地区覆膜玉米降解地膜筛选试验
Screening of Degradable Mulching Film on Maize in Cold Region and Semi Arid Area
摘要
Abstract
For the selection of suitable degradable film applied to corn production in semiarid area and to reduce the environment pollution, the effects of different degradable mulch films with degradation time on the yield of maize were studied .The results showed that the film covering for 50~70d began to appear degradable, would not reduce maize yield and could be achieve the same soil warming effect with conventional film. And the degra-dation did not influence the moisture of maize root direct supply, but promoted the corn yield ,reduced the resid-ual film on farmland environmental pollution .So degradable mulching film cultivation in cold semiaridarea had fast degradation speed, No. 2 and No. 5 which began to appear cracks in induction period after filming for 50~70d were suitable .关键词
