研究了在稻田放养不同密度的3种蛙类（青蛙、牛蛙和泽蛙）对早稻、晚稻主要性状和主要害虫发生的影响。结果表明：放养蛙类对水稻农艺性状及有效穗数、千粒重无显著的影响，但对每穗粒数、结实率和稻谷产量有显著的影响；与空白对照相比，放养较高密度的青蛙或牛蛙可以显著提高水稻的每穗粒数、结实率和稻谷产量；放养3种蛙类对稻飞虱和稻纵卷叶螟均有一定的防治效果，以放养青蛙或牛蛙的防效较好，且放养密度越高防效越好，但均不及施用普通药剂的防效。

The effects of three various batrachia ( Rana nigromaculata, Rana catesbeiana and Rana limnocharis) and their den-sities on the main traits of early rice and late rice as well as the occurrence of main insect pests in paddy were studied .The results showed that rearing batrachia in paddy had no significant effects on the agronomic traits , number of effective spikes per unit area , and 1000-grain weight of rice , but had significant influences on the number of grains per spike , seed setting rate , and grain yield;in comparison with the blank control , rearing higher density of frog or bullfrog could significantly enhance the number of grains per spike , seed setting rate , and grain yield of rice;the three batrachia all had a certain control effect on rice planthopper and rice leaf roller, but frog and bullfrog had better control effect , and the higher their density was , the better their control effect was , but the control effect of batrachia was lower than that of applying common insecticides .
