通过在扦插速生杨育苗地行间散播白菜籽来对杨树林地中的黑绒金龟子进行驱避试验,结果表明：速生杨扦插育苗地撒播37.5 kg·hm-2的白菜籽就能驱避住黑绒金龟子的危害,不但有效地防治了黑绒金龟子危害,而且克服了大量喷洒农药对土壤的污染。撒籽量在37.5~45 kg·hm-2,防治黑绒金龟啃食幼芽或幼叶的效果可达100%。
通過在扢插速生楊育苗地行間散播白菜籽來對楊樹林地中的黑絨金龜子進行驅避試驗,結果錶明：速生楊扢插育苗地撒播37.5 kg·hm-2的白菜籽就能驅避住黑絨金龜子的危害,不但有效地防治瞭黑絨金龜子危害,而且剋服瞭大量噴灑農藥對土壤的汙染。撒籽量在37.5~45 kg·hm-2,防治黑絨金龜啃食幼芽或幼葉的效果可達100%。

Experiments of dispersing Serica orientalis in poplar forestland were conducted by scattering cabbage seeds.Result shows that scattering 37.5 kg hm-2 cabbage seeds can disperse Sericaorientalis.Not only control ef-fectively the damage of Sericaorientalis,but also overcome the difficulties of polluting the soil by spraying pesti-cides.Seed-scattered amount of cabbage seeds are 37.5-45 kg·hm-2 ,effect for controlling Sericaorientalis which chewed buds or leaves will reach 100%.
