生物降解地膜自然降解过程及其对玉米生长发育和产量的影响
Degradation of Biodegradable Mulch Film and Its Effect on Growth and Yield of Maize
摘要
Abstract
Using biodegradable films are an efficient approach to reduce the white pollution by traditional plastic film which could remain in soils for hundred years.The degradation characteristics of biodegradable mulch films and its effect on the growth of maize were analyzed and tested.The results indicated that：（1） The degradation percentage of biodegradable mulch films was 1.26% within 60 days and 1.91% within 100 days respectively,and the remained film degraded greatly afterward.（2） No obvious difference has been detected between biodegradable and the common plastic films in the effect on the increase of the soil temperature.（3） The biodegradable mulch film could increase the leave area evidently,and 10.83%,9.38% and 7.94% increase has been observed above,at and below the corncob respectively,which would improve the growth.（4） The yield with degradable film mulching was about 18.7% higher than that without film mulching,but there are no obvious difference between it and the plastic film.关键词
