为了探明稻田养鸭对水稻纹枯病的发生、发展的影响,为稻-鸭复合系统中水稻纹枯病的防治提供依据,笔者在中稻、晚稻田进行了稻田养鸭试验.试验结果表明,在中稻田每666.7m2放养体重150 g左右鸭子15～20只,能使纹枯病病蔸率减少56.0%,病株率减少57.74%,同时比用井岗霉素防治的小区病蔸率下降9.0%,病株率下降15.25%,病情指数比空白对照下降26.46,比施用井岗霉素的施药区减少0.95;防治效果显著,基本可控制纹枯病的危害.

To study and document the occurrences and developmental influence of feeding ducks in rice paddies on rice sheath blight, and to provide the basis of rice sheath blight prevention and treatment in a rice-duck compounded system. Through the accounts and trials of feeding ducks in middle rice and late rice fields by the author, the results indicated that: in every 666.7m~2 middle rice paddy fields, 15～20 ducks weighing about 150 g each were fed, duck usage reduced the ratio by 56.0% in diseased hills of rice sheath blight. The ratio of diseased ...
