摘 要:为了防治白菜根蛆等地下害虫和菜青虫等食叶害虫,间接防治软腐病和病毒病等病害所造成的损失,采用40%辛硫磷EC 1 000倍液灌根,以及用40%辛硫磷EC 800倍液喷雾,从而达到防治病虫和增产的目的。根据2008年吉林市白菜平均价格计算出经济效益,单纯灌根与喷雾分别获得2 900.0元/hm2和1 200.0元/hm2的经济效益,同时进行可获取4 820.0元/hm2的经济效益。In order to prevent and control the loss which the cabbage root maggot soil insect and vegetable worm plant diseases and so on and so on food leaf harmful insects, indirect prevention soft rot and viral disease create, Dilutes 1 000 time of fluid solutions with 40% phoxim EC to fill the root, as well as 40% phoxim EC 800 time of fluid atomization, thus serves the production increase purpose. The Jilin cabbage average price calculates the economic efficiency according to 2008, Fills the root with to atomize purely each hectare to obtain 2 900.0 Yuan and 1 200.0 Yuan economic efficiencies separately, simultaneously carries on may gain 4 820.0 Yuan economic efficiencies.
