稻鸭共作模式有机肥组合施用效果研究

Study on Effects of Combined Organic Fertilizer Application in Rice-duck Integrated Farming Model

目的:探索稻鸭共作模式下有机肥组合施用效果,解决有机肥合理搭配和施用量问题。方法:采用随机区组设计,对不同有机肥组合施用效果进行抽样检测。结果:供试田块每667m2施用水稻秸秆堆肥1 000kg+菜籽饼50kg+鸡粪50kg或水稻秸秆堆肥1 200kg+鸡粪200kg,可获得有机稻380kg以上的产量。结论:稻鸭共作模式下,施用合理组配的有机肥不仅能够平衡土壤养分供应,维持地力,而且能够优化水稻经济性状,提高水稻产量,但对有机稻米品质的提高没有明显作用。

Objective to explore the effects of combined organic fertilizer application in Rice-Duck Integrated Farming System （RDIFS）,in order to solve the problems of reasonable combination and application rate of organic fertilizers. Methods adopt a randomized block design and test the effects of different organic fertiliz-er combination samples. Results By using 1000kg rice straw compost plus 50kg rapeseed cake plus 50kg chicken manure or 1200kg rice straw compost plus 200kg chicken manure in every 667m2 test plot,the or-ganic rice production can reach 380kg.Conclusion RDIFS,the application of organic fertilizer with reason-able combination ratio can reach ance the soil nutrient supply and maintain the soil fertility,but also im-prove the rice yield and optimize the rice economy. However,it has no significant effect on organic rice quality improvement.
