今年在农业生产大跃进的形势下,我省治虫工作也有了很大跃进,各地普遍开展了群众性的防治运动,为农业增产提供了保证,并且还出现了31个无螟害县,4个无稻苞虫害县;但是害虫对农业生产的威胁尚未解除,特别是我省自1956年普遍采用混栽、密植和增肥的农业技术后,病虫繁殖蔓延更为厉害,如1958年稻苞虫、稻飞(凡虫虫)、浮尘子,稻瘟病,从卷叶虫和水稻螟虫等普遍发生,即是一例;因此对于防治害虫的工作,不仅不应放松,而且还必须加强。目前正是水稻害虫和病菌潜伏越冬的时候,由于去冬今春气候特别温暖,今年将更有利于它们安全越冬,成活率高而死亡率低,这样必将导
This year, with the great leap forward in agricultural production, the work of pest control in our province has also made great leaps. Mass-oriented prevention and control campaigns have been widely carried out throughout the country, providing a guarantee for increasing agricultural output. In addition, 31 non-stemming counties, 4 However, the threat of pests to agricultural production has not yet been lifted, especially since the agricultural technology of mixed planting, close planting and fertilization is widely used in our province since 1956, the spread of pests and diseases is even more serious. For example, in 1958, Insects, rice fly (all kinds of insects), floating dust, rice blast, from leaf roller and rice stem borers and other common occurrence, that is an example; so for pest control work, not only should not relax, but also must be strengthened. At present, when rice pests and pathogens lurk overwintering, due to the particularly warm climate during the winter and spring, this year will be more conducive to their safe winterization, high survival rate and low mortality rate, so will guide
