地膜棉田温湿效应与应用

The Temperature and Humidity Effects of The Film Mulch Cotton Field and Their Application

通过对有膜棉田和无膜棉田的温度、湿度的对比试验分析,结果表明,棉田盖膜在前期有增温保湿作用,并且使棉株生理活动加强,物理过程减弱,有利于棉花干物质的积累,使棉花产量和品质都有所提高。

According to the comparative experiment and analysis of the soil temperature and soil humidity between the film mulch cotton field and no film mulch cotton field,the results indicate that the cotton field covered with film mulch can raise the soil temperature and humidity at the youthful cotton period,can reinforce the cotton′s physiololgical activity and can reduce the cotton′s physical process.It is favourable for the cumulation of the dry-substance.It improve the production and the quality of the cotton.
