怎样防治土壤里的害虫

Miss Chen

土壤里的害虫又称地下害虫,种类很多,其中对花卉危害性较大的有蝼蛄、蛴螬、地老虎、金针虫等,这几种地下害虫除蝼蛄以幼虫和成虫同时危害外,地老虎、金针虫等都以幼虫危害。

土壤里害虫的特点是长期潜伏在土中,食性很杂,危害时期多集中在春、秋两季。北京地区主要在4~5月间活动猖獗。防治土中害虫应采取农业措施和药剂防治相结合的方法如下:
①苗畦要适当深耕细作,消除杂草,以利花卉生长发育,增强抗虫害能力;另一方面适当深耕,使土中害虫的生活条件恶化,从而抑制害虫的发育和繁殖;



②施用有机肥料必须充分腐熟,木腐熟的有机肥料,如饼肥或粪肥,能诱使多种害虫发生;

③用农药敌百虫粉剂处理土壤。用l份敌百虫粉与细土50份拌匀,直接撒布苗畦,然后翻入土中或开条沟撒人;也可以将敌百虫粉与肥料混合,作基肥或追肥施人土中,对蝼蛄、蛴螬、金针虫等均有良好的防治效果;

④人工捕捉幼虫或成虫。清晨在断苗的周围或见残留的被害茎叶的洞口,将土扒开,可找到黑褐色肉虫,即为金龟子幼虫。还可利用金龟子的假死性于黄昏敲震花卉枝条捕杀;

⑤盆养花卉可在培养土中掺敌百虫粉剂防治土中害虫,宜在使用前1周均匀掺入。平时盆土中发现蛴螬、蚯蚓等害虫,也可用敌百虫稀薄溶液点浇除治。
