据调查,各种害虫从早稻田转移到晚稻田,以秧田为重要桥梁的主要有螟虫,稻纵卷叶螟、稻飞虱、稻蓟马等.种类甚多,数量亦大,并且由于发生期不一,各种害虫的虫态又极复杂,同时也有各种不同虫态的害虫天敌.因此改进用药技术是一项很重要的技术环节,本试验示范目的是要做到集中消灭、严防扩散,又能保护害虫天敌,以及节省用药,省工省本收到了事半功倍的效果.

According to the survey, all kinds of pests are transferred from the early rice fields to the late rice fields, and the main bridges that use the seedling as the main bridge are the stem borers, the rice leafrollers, the rice planthoppers, the rice thrips, etc. There are many types and quantities, and as the occurrence period Different insect states are extremely complex and also have various insect pest natural enemies. Therefore, improving drug use technology is a very important technical link. The purpose of this experiment is to eliminate it centrally and prevent it from spreading , But also to protect the natural enemies of pests, as well as save medication, the provincial labor province received a multiplier effect.
