Effects of Different Types of Film Mulching on the Growth of Forage Maize and Soil Hydrothermal Status in Dry Farming Areas
摘要
Abstract
In order to identify suitable types of mulching film for maize production in dry farming areas,the effects of fully biodegradable film,water-permeable fully biodegradable film,and conventional PE film on forage maize growth,yield,soil hydrothermal condition,and film residue were investigated.The results showed that,compared with conventional PE film,the fully biodegradable and water-permeable biodegradable films entered the induction phase(crack<1 cm)at 25 and 35 days after mulching,respectively,the rupture phase(crack>3 cm)at 78 and 82 days,and the disintegration phase(crack>5 cm)at 148 and 156 days.Compared with PE film,maize emergence and jointing stages were delayed under biodegradable films,while the trumpet stage,tasseling stage,and early dough stage occurred earlier.Soil moisture in the tillage layer decreased by 11.66%and 5.61%at the trumpet stage,and by 19.52%and 7.14%at the milking stage,respectively.Soil temperature declined slightly during the early growth stage(seedling to jointing),but declined more noticeably during the later stage(from trumpet onward).The yield of fresh maize stalk decreased significantly by 12.39%and 13.34%(P<0.05),while mulch film input cost increased by 100%and 125%,and gross profit decreased by 10.60%and 12.51%,respectively.Meanwhile,film residue was reduced by 58.33%and 33.33%.Overall,although the use of biodegradable films led to a certain reduction in biomass yield and profit due to higher costs,the significantly lower film residue compared to PE film is conducive to the sustainable and high-quality development of the forage maize industry in arid rainfed agricultural regions.关键词
