摘　　要：在稻田中,放养鸭子的密度为10,20和30只/667m2。根据试验田的面积,将110只巢湖麻鸭随机分为4组,经58d的稻鸭共生试验表明,稻鸭共生技术具有良好的稻田除虫、除草和防水稻病害效果。在稻田中放养鸭子20只/667m2时,具有良好的鸭只生长情况和最高的水稻产量,为最佳放养密度。To investigate the effects of rice-duck integrated farming,a total of 110 Chaohu spot ducks were randomly assigned into four groups and stocked at four densities,0,10,20 and 30 ducks/667m^2,respectively.After a 58 d rice-duck integrated farming,good effects of this technology on deinsectization,weed eradication and disease control of paddy field were observed.Good duck growth and the highest rice yield were achieved when the stocking density was 20 ducks/667m^2.
