近几年来,根结线虫为害日益加剧,广泛侵害瓜、茄、豆类蔬菜、芹菜和多种十字花科蔬菜。杭州郊区虽已引进米乐尔等高效土壤杀虫剂,但因土壤施药不易均匀,较难取得理想的防治效果。北方菜区使用秸秆酿热,太阳辐射升温,地膜覆盖蓄热三管齐下,利用热力杀线虫,并在酿热物中添加碳酸氢铵肥料,利用氨气熏杀,可助一臂之力,防效高达95%以上;而且也可培肥土质,改良土壤,南方菜区不妨一试。三伏天气,烈日当空,正是利用太阳辐射升温的大好时机。此时,瓜茄果菜
In recent years, root knot nematode damage intensified, a wide range of damage melon, eggplant, beans vegetables, celery and a variety of cruciferous vegetables. Although the suburbs of Hangzhou have been introduced such as Mole and other highly effective soil insecticides, but because of soil application is not easy uniform, more difficult to obtain the desired effect of prevention and treatment. Northern District, the use of straw-stuffed brewing heat, solar radiation warming, three-pronged coverage of plastic film heat, the use of heat to kill nematodes, and in the stuffing of fermented ammonium bicarbonate fertilizer, the use of ammonia fumigation can help one hand, Up to 95% or more; but also soil fertility, soil improvement, the Southern District may wish to try. Three-day weather, hot sun, it is a good time to use solar radiation warming. At this point, melon fruits and vegetables
