通过近几年棉花地膜覆盖栽培的生产实践,我们发现地膜覆盖后,在播种出苗期间,如遇到温度高、湿度小的天气时,经常发生高温烫苗现象,严重影响苗全苗壮,进而导致减产。为了摸清高温烫苗的规律和预防方法,创造棉花苗期优越的农业气象条件,我们于 Through the practice of cotton mulching cultivation in recent years, we found that during the seedling emergence, when the weather is high and the humidity is low, we find that the phenomenon of high temperature hot seedling often occurs and seriously affect the seedlings’ Lead to cut. In order to find out the rules of high temperature hot seedlings and prevention methods to create superior cotton seedling agro-meteorological conditions, we
