摘要
在冷凉山区生态环境中，油菜是油料作物的传统作物，但由于越冬死苗问题，致使油菜生产长时期地效益不大。为此，我们对冷凉生态区油菜覆盖间作制进行了试验、观察和调查。目前由于一些地区采用了这一栽培措施，已取得了一定经济效益，值得同类地区推广试用。
Cole wore is one traditional oil group in cool ecological region of mountain area. In order to solve the problem of seeding death through the winter, which causing long termed low benefits of cole wore production, we investigated and tested the method of intercropping of covered cole wore. In recent, after this method was spread with the obvious economic benefits. it is desirable to further spread it in similar regions.
