近年来,我省不少农户应用地膜覆盖栽培大豆,获得了较好的经济效益。但也有部分农户因技术掌握不好,出现早出苗受晚霜危害,高温烫芽、烫苗和生育期过长秋霜前不能正常成熟,造成减产的现象。为此,我们经过调查研究提出寒地大豆地膜覆盖栽培要点。
In recent years, many farmers in our province use plastic film mulching cultivation of soybean, get better economic benefits. However, some peasants may not be able to properly mature due to poor technical mastery, early emergence of late frost damage due to late frost, high temperature hot buds, hot seedlings and long frosty autumn frost, resulting in a decrease in production. To this end, we put forward the investigation of cold winter soybean film mulching points.
