近年来,我县大面积推广“两段育秧”(温室内无土育秧,三叶期出室,寄栽于秧田,培育壮秧后待插),因其秧龄长,秧苗旺,二化螟卵块密度大,是一代二化螟主要虫源田。秧苗栽插早,提前封行,又是水稻纹枯病的重发田。北方水稻夏插季节,劳力紧张,与水稻病虫草防治矛盾突出。我县稻田草为害严重,为此,采用底施农药的方法,将稻田耕翻灌水,粗耙后,用25％杀虫双水剂,25％杀虫脒水剂、50％杀扑隆可湿性粉剂、50％多菌灵可湿性粉剂、兑细潮土30—40斤,均匀撒施,再细耙整平,隔日栽 In recent years, a large area of ​​our county to promote “two sections of seedlings” (greenhouse soilless seedlings, three-leaf stage out of room, planted in the seedling field, strong seedlings to be inserted later), because of its long seedling, Egg mass density, the main generation of striped stem borer field. Seedlings planted early, ahead of the closure line, but also the second crop of rice sheath blight. Northern rice summer plug season, labor-intensive, prominent contradiction with the prevention and control of rice diseases and insect pests. For this purpose, the method of applying pesticides at the bottom of paddy field was used to pollute paddy fields and rough rake. After 25% pesticide dianhydride and 25% Wettable powder, 50% carbendazim wettable powder, against the fine soil 30-40 pounds, spread evenly, then fine rake leveling, planted every other day
