摘　　要：在贵州省黔东南州山区开展“稻鱼鸭”生态种养研究示范,实现稻田每667 m2总产值达到6047.9元,比水稻单种增加4237元,经济效益显著。“稻鱼鸭”生态种养模式可提高土壤的肥力,土样检测结果显示,与试验前对比,有机质含量增加2.3~3.5 g/kg,土壤全氮含量百分比增幅0.032%~0.052%,有效磷含量增加2.2~4.3 mg/kg,速效钾含量增加2.0~16.0mg/kg,还能有效控制病虫草的危害,减少农药、化肥的施用,减轻稻田环境污染,提高农产品品质。该模式具有较高的经济效益、生态效益和社会效益。The ecological cultivation model of“rice-fish-duck”was carried out in the mountainous area of Qiandongnan Prefecture,Guizhou province.The total output value of rice paddy per 667 m2 reached 6047.9 yuan,an increase of 4237 yuan compared with that of rice monoculture,and the economic benefits were significant.The ecological cultivation model of“ricefish-duck”can improve soil fertility.The results of soil samples showed that compared with before the test,the content of organic matter increased by 2.3~3.5 g/kg,the percentage of total nitrogen increased by 0.032%~0.052%,the content of available phosphorus increased by 2.2~4.3 mg/kg,and the content of available potassium increased by 2.0~16.0 mg/kg.It can also effectively control the harm of diseases pests and weeds,reduce the application of pesticides and fertilizers,reduce the environmental pollution of rice fields,and improve the quality of agricultural products.It has high economic,ecological and social benefits.
