| 摘 要： | 本文根据调查结果认为，由于水稻抛秧栽培避 过或缩短早、晚稻秧田遇 第一、三代三化 螟卵的机会，致使第一、三代三化螟种群数量下降，从而降低第二、四代三化螟的发生量和为害程度。抛秧地区秧田和本田三化螟的药剂防治次数可以减少。

| Abstract: | Because using throwing seedling technique can stagger or the chance of early and late rice seedling beds infected by the first and third generation yellow rice borers' ova, the population of the first and third generation yellow rice borers can go down. The occurring and damage of the second and forth generation yellow rice borers also can go down. The number of chemical control to yellow rice borer can be reduced in seedling beds and fields of throwing seedling area. |
