稻鸭共生与牧草轮作生态农业模式的效果研究

Effects of Rice-Duck Integrated Farming and Pasture Rotation Ecological System

为解决大面积稻鸭共生地区养鸭所带来的恶臭和水系污染问题,并探讨稻鸭共生和紫云英轮作对周围环境和水稻生长等的影响,试验设四个处理组,分别为:稻鸭共生组(T1)、稻鸭共生+紫云英轮作组(T2)、稻田种紫云英不养鸭组(T3)、稻田不养鸭不种紫云英的传统种稻对照组(CK)。结果表明:稻鸭共生和紫云英轮作能使水稻生长更良好,得到更高的水稻产量;稻鸭共生和紫云英轮作对稻鸭农业的农业用水水质污染改善有效果;稻鸭共生和紫云英轮作能改善土壤的理化性状,相比对照组提高土壤有机质含量达0.54 g/kg,并能提高土壤中速效养份的含量;稻鸭共生和紫云英轮作,能较好地起到杂草和虫害防治效果。

In order to reduce a bad smell and the pollution of water happening in a large scale Rice-Duck Integrated Farming,this research was planed,it was also conducted out to investigate whether the combination method of Rice-Duck Integrated Farming and Astragalus sinicus Rotation have influence on environmental problems and growth and yields of rice,ect.The test was designed four groups： Rice-Duck Integrated Farming region（T1）、Rice-Duck Integrated Farming and Astragalus sinicus Rotation region（T2）、Only plant Astragalus sinicus region（T3）、 Traditional rice-growing region（Not Rice-duck farming and not planting Astragalus sinicus in rice fields,CK）.Results were shown that Rice-Duck Integrated Farming and Astragalus sinicus Rotation can promotion rice growth better and get a higher rice yields,and improve agricultural water quality.It was also improve physical and chemical properties of soil by increasing organic matter 0.54g/kg and available nutrient,over CK.Besides,it can effectively controll weeds and pest.
