郑州市郊齐礼阎大队是一个以蔬菜生产为主的大队。每年蔬菜种植面积一千六百亩左右,产鲜菜约一千万斤。然而由于虫害问题,每年用于化学农药的经费近一万元,不仅成本较高,而且有残余毒害,直接影响人民的身体健康。再者,由于害虫不断产生抗药性,每年施药量不断增大。因此,选用效果好、成本低、能土法上马,自已生产,无残毒的生物农药便成为目前生产上的迫切任务。 Qi Li Yan suburb of Zhengzhou is a vegetable production-based brigade. Every year about 1,600 acres of vegetable cultivation area, yield about 10 million pounds of fresh vegetables. However, due to pest problems, the annual funding for chemical pesticides is nearly 10,000 yuan, which not only causes high costs but also has residual poisonings and directly affects people’s health. Furthermore, as pests continue to develop resistance, the amount of pesticide applied annually increases. Therefore, the selection of effective, low cost, can be launched by native soil, their own production, non-residue biological pesticide has become an urgent task of production.
