湖北省普遍推广666泼浇或撒毒土防治螟虫。这两种方法防治枯心苗效果都很好。特别是撒毒土工作方便,工效高。但是,撒毒土很难将白穗率压低到1%以下。 1964年我省黄冈专区治螟示范样板,在防治早稻白穗时,总结了浠水县群众提小桶下田泼浇治螟的方法后,进行了示范推广。比过去大桶泼浇方便多了,但是操作时打湿衣裤,损伤禾苗,工效不高。在第三代治螟时,罗田县群众便提出先分廂再提小桶下田泼浇的办法,在第四代二季晚稻防白穗时,黄冈县全面推广了这个方法,效果很好,白穗率都压低在1%以下,颇受群众欢迎。 根据各地经验总结,分廂小桶泼浇防白穗,有
Hubei Province to promote the general pour 666 sprinkle or sprinkle soil control stem borers. These two methods to control the effects of dry seedlings are good. In particular, the work of spreading poisonous soil is easy and effective. However, sprinkling toxic soil is difficult to lower the white spike rate below 1%. 1964 Huanggang area in our province governance borer demonstration model, in the prevention and treatment of early rice Baisui, summed up the masses in Xishui County to mention the method of Shimoda pouring governance borer, the demonstration promotion. Pouring than the past lot easier pouring, but when operating wet underwear, injury seedlings, ergonomics is not high. In the third generation of control borer, Luotian County, the masses put forward the first sub-box and then mention the method of Shimoda Shimoda pouring, in the fourth generation of the second season of late rice anti-white spike, Huanggang County comprehensive promotion of this method, the effect is good, white spike Rates are down below 1%, popular among the masses. According to the experience of all over, sub-compartment keg sprinkle sprinkle anti-white spike, there
