为了探明稻田养鸭对水稻病虫害的控制作用,于2003年4至11月在湖南省桃江县建立稻田养鸭试验示范区.研究结果表明,在中稻田,放鸭区第四代、第五代稻飞虱百蔸虫量较空白区虫量下降70.2%和72.4%;晚稻田养鸭区第四代、第五代稻飞虱虫量较空白区下降56.2%和64.7%,表明稻鸭共栖对稻飞虱起到了稳定、持久的控制作用.放鸭区不需用药防治稻飞虱,经济效益明显.

In order to prove up the controllable effect of feeding ducks in paddy fields on rice diseases and insect pests,the authors established a trial area for feeding ducks in rice paddy from April to November of 2003 in Taojiang County of Hunan province.The results indicate that in semi-late rice paddy, the worms quantity of the forth and fifth generations of the quantity of rice planthoppers every 100 hills is lower by 56.2% and 64.7% respectively than that in blank area. Rice-duck commensalisms have a steedy and long controllable effect on rice planthoppers. It is unnecessa...
