可降解地膜对土壤、温度水分及玉米生长发育的影响
Effects of degradable film on soil temperature, moisture and growth of maize
摘要
Abstract
Aiming at reducing agricultural pollution caused by plastic film, effect of degradable film on soil temperature, soil moisture, maize growth and development, maize yield and relevant characteristics were studied through comparing with the plastic film and open field. The results indicated that soil temperature at surface and 10 cm depth in two months after sowing, soil moisture in 0-20 and >20-40 cm profile from sowing to big trumpet stage, were all higher for degradable film covering than open field. Growth progress, seedling rate, root number during shooting stage, plant height, leaf area and dry weight of maize in different stages were all higher for degradable film covering. Kernel number, thousand-grain weight, and yield of maize under degradable film covering were increased by 9.6%, 20.9%, 35.1% respectively. Degradable film did not show significant difference with plastic film, and it could be applied to agriculture instead of plastic film.关键词
