生物降解膜在玉米上的应用效果研究

Effect of the Biodegradable Film on Maize

为探索玉米绿色生产模式,采用随机区组设计田间试验,对覆盖生物降解地膜、普通PE地膜、不覆盖地膜处理的玉米出苗率、生育期、生长性状、产量、杂草生长情况进行分析。结果表明:覆膜能缩短玉米生育期,覆盖生物降解地膜、普通PE膜分别比不覆盖地膜提前5d、9d,生长势较强,抑制了杂草的生长。覆盖生物降解地膜单产最高,达786.17kg/667m2,分别比普通PE膜与不覆盖地膜高4.3%、27.6%。建议生产上推广应用生物降解地膜。

To explore maize green production, biodegradable film, PE film and no film covering was applied on maize field test by ran- dom block disign, and compared the seeding rates, growth periods, growth characters, yield and weed growth among different treat- ments, the results showed that film covering can reduce the growth zperiods of maize, under treatment of biodegradable film, PE film covering can reduce 5days, 9days, respectively, which also can inhabit the growth of weeds. The yield of biodegradable film is the greatest, it＇ s 786.17kg/667m2 ,4.3% , 27.6% greater than PE film covering and no covering. So it＇ s able to apply biodegradable film on maize production.
