渗水降解地膜在大豆田间应用效果的综合分析
Comprehensive Analysis of Application Effect of Water Seepage Degradable Mulching Film in Soybean Field
摘要
Abstract
In order to clarify the effects of water seepage degradable mulching film on water retention and warming of soil plough layer and its effects on the growth and yield of soybean,a field experiment was conducted on the outskirts of Changchun,Jilin province,with annual rainfall of 582 mm and climatic conditions of spring drought.This paper presented two models of ordinary plastic and no cover film treatment.The single factor randomized block design was used to measure the water content and temperature of each layer,agronomic characters,mechanical indexes of water seepage degradable mulching film and ordinary plastic at emergence stage,seedling stage,flowering stage and podding stage respectively,the economic charactern were measured after harvest.The results showed that the water seepage degradable mulching film effectively received rainwater while maintaining the soil moisture,the soil moisture content was significantly higher than that of ordinary plastic.The temperature of soil plough layer increased under both water seepage degradable mulching film and ordinary plastic condition.In the early stage of development with lower temperature,the effect of water seepage degradable mulching film was better than that of ordinary plastic.And when the temperature turned higher,water seepage degradable mulching film to adjust the inside temperature though the film holes,then making the temperature was lower,so as to protect the soybean roots.Compared with ordinary plastic,water seepage degradable mulching film had less effect on the tensile strength and elongation at break,and with the passage of time,the decline was even greater.Water seepage degradable mulching film gradually degraded in the soil.Water seepage degradable mulching film and ordinary plastic effected on promoting the growth and yield of soybean.And the soybean covered with water seepage degradable mulching film grew better.Compared with no cover film treatment,there were obvious increases in yield,with the ranges of 21.56％ and 10.98％ per plant in yield.关键词
