不同地膜覆盖对土壤温度、杂草控制和甜玉米生长的影响
Effects of different plastic film mulching on soil temperature,weed control and growth of sweet maize
摘要
Abstract
In order to explore the cultivation effects of plastic film mulching on sweet maize in Pudong of Shanghai,the soil temperature,weeds under film mulching,and maize yield under different mulching were studied using'Shenxuetian 1'as the material.The results showed that compared with no mulching(CK),plastic film mulching significantly increased soil temperature,and increased maize plant height,panicle height,stem diameter,plant dry weight and panicle yield.Among the 3 different film mulching treatments,the black film treatment(T2)had the worst effect on raising soil temperature,but the inhibition effect of weeds was the best,with an average control effect close to 100％,followed by the black and white film treatment(T3),with an average control effect of 45.5％.However the white film treatment(T1)promoted the growth of weeds in the early growth stage of maize,but had a better effect on raising soil temperature,maize plant height,panicle position,dry matter weight,panicle characteristics and yield than other treatments.Among different treatments,the yield of maize panicle was highest in the white film treatment,which increased by 20.6％compared to the control,followed by black and white film treatment and black film treatment,which increased by 11.3％and 6.6％respectively compared to the control.关键词
