通过田间调查和室内接虫试验,证实排水晒田的治蝗效果和增产作用比较显著:排水晒田的枯心率,平均3.16—3.50％;经常深灌的枯心率,平均7.18—8.02％。排水晒田的稻株比经常深灌的稻株,平均增产27.0％。木文从诱集成虫产卵、对幼虫的抗性和对蝗虫为害后的补偿作用等进行分析和讨论。 Through the field investigation and laboratory tests, it was found that the effect of controlling locusts and increasing the yield of drainage sunshade was significant: the dry heart rate of drainage sunshade averaged 3.16-3.50%; the dry heart rate of frequent deep irrigation was 7.18-8.02% on average. Drainage drying rice than regular deep-irrigation rice, an average increase of 27.0%. Muwen from the trap of adult eggs, the resistance of larvae and the compensation for the role of locusts after the analysis and discussion.
