根据我所“六五”期间取得的研究结果对当地秧田以二化螟为主,本田稻飞虱和稻纵卷叶螟(或稻瘟病)同步发生这一实际情况,采用不同方法,不同农药配方进行万亩以上的示范,结果表明;大粒法对二化螟防效达85.5～90.3％吹雾法和弥雾法的农药用量比常用量减少35％左右,对稻飞虱、稻纵卷叶螟及穗稻瘟的防效仍达94％以上。示范区每亩比群众自防区多收干谷31.1公斤,未施药和仅防治一次的比示范区减产47.3～83.7％。农药在糙米中的残留量比常规法减少52.4～54.3％。示范区吹雾、弥雾每亩药费比常规喷雾减少1.84元,比农户减少3.9元。同时避免人畜中毒和减轻对环境的污染。
According to the research results obtained during the period of “the 6th Five-Year Plan” in our country, the occurrence of the rice stem borers in the local seedling fields is the main fact. The Honda rice planthoppers and the rice leaf roller (or rice blast) simultaneously occur under the same conditions. Different pesticides The results showed that the effect of big grain method on the stem borer was 85.5-90.3%, the amount of pesticide used in the method of blowing fog and misting was reduced by 35% Borer and spike blast control effect still reached 94%. Demonstration area per mu than the masses more self-defense area overwhelmed 31.1 kilograms of dry valley, no pesticide application and control only once the demonstration area cut 47.3 ~ 83.7%. Pesticide residue in brown rice than the conventional method to reduce 52.4 ~ 54.3%. Demonstration area blowing fog, Mie Wu per mu than conventional spray to reduce 1.84 yuan, 3.9 yuan less than farmers. At the same time to avoid human and animal poisoning and reduce environmental pollution.
