摘　　要：就稻田养雌鸭(180只/hm2)不施农药、稻田养雄鸭(180只/hm2)不施农药、稻田施农药不养鸭、稻田不养鸭不施农药4个处理的生态经济效益进行了比较试验。结果表明:各处理粮食产量依次为6201.0kg/hm26、153.0kg/hm2、5995.5kg/hm24、518.0kg/hm2,分别比稻田不养鸭不施农药的增产27.14%、26.57%、24.64%。其中稻田养雌鸭不施农药处理比稻田施农药不养鸭模式增产水稻3.4%,增收成鸭324kg/hm2;养鸭不施农药的水稻病虫草害的综合防治效果为76.5%,其中防病效果为91%,防虫效果达74.5%,杂草控制系数为0.64。可见稻田养鸭不施农药是一种良性循环高效生态农业模式。Four patterns of raising trigamous duck without applying pesticide in paddy fields, raising grand duck without applying pesticide in paddy fields, applying pesticide with raising duck in paddy fields and neither applying pesticide nor raising duck in paddy fields were compared. The results showed： rice yield was 6 201.0 kg/hm^2 ,6 153.0 kg/hm^2 ,5 995.5 kg/hm^2 ,4518.0 kg/hm^2 respectively, 27.14% ,26.57% ,24.64% more copmared with neither applying pesticide nor raising duck in paddy fields respeetively. Compared with the patter of applying pesticide without raising duck in rice fields, the pattern of raising trigamous duck in paddy fields increased 3.4% in rice yield, gained 324 kg/hm^2 in duck flesh and produced 76.5% in disease- insect- weed prevention and control（91% in disease resistance, 74.5% in insect prevention, 0.64 in weed controlling ability）, Raising duck without applying pesticide in paddy fields was a type of high efficient eeo- agriculture pattern with beneficial circle.
