贵州省冬油菜在播种后,不少地方的幼苗成片死亡,给油菜生产造成极大损失。除与雨水、低温和病害等相关外,油菜跳甲危害嫩苗生长点,行毁灭性的致命打击,是一个很重要的原因。因此,我们就油菜跳甲发生为害等情况作了初步的探讨,为防治油菜跳甲,促进油菜生产,获得高产丰收提供依据。 Guizhou rapeseed after planting, many places of seedlings died, causing great losses to the production of rapeseed. In addition to the rain, low temperature and disease, etc., rape beetle harm the tender growth point, the devastating fatal blow is a very important reason. Therefore, we conducted a preliminary study on the occurrence of rape beetle damage and other conditions for the prevention and control of rape beetle to promote rapeseed production and provide a basis for high yield harvest.
