摘　　要：为探明稻田养鸭对水稻纹枯病的防控效果,进行了稻鸭共作对水稻纹枯病的影响试验。结果显示,在稻鸭复合生态系统中,水稻纹枯病平均病蔸率为22.22%、平均病株率为8.06%、病情指数为17.95,与常规用药处理区相比,病蔸率下降6.34%、病株率下降6.12%、病情指数下降0.89。表明稻田养鸭可以基本控制纹枯病的危害,适宜大面积推广应用。In order to study the effects of raising duck in rice field on controlling rice sheath blight, the rice-duck integrated farming was experimented. The results showed that the average rate of diseased hills, diseased plants and the disease index of rice sheath blight was 22.22%, 8.06%, and 17.95, respectively. As compared to treatments applying pesticides, the diseased hill rate, diseased plant rate, and disease index was decreased by 6.34%, 6.12% and 0.89, respectively. It is indicated that duck-raising in rice field could control rice sheath blight and could be extended in larger scale.
