摘要
【目的】为进一步探索免耕稻田养鸭技术,提高免耕稻田养鸭效益,为大面积推广应用提供科学理论依据。【结果】养鸭区总产值37982元/hm^2,比对照区22071元/hm^2增15911元,增长72.1%;养鸭区纯收入为17052.5元/hm^2,比对照区7756.5元/hm^2,增9296元/hm^2,增长140.5%。同时还能达到生态、环保的目的。【结论】免耕稻田养鸭不但减少稻田的田间杂草,减少水稻病虫害的发生,特别是减少稻飞虱、纹枯病的为害,而且还可以减少水稻无效分蘖,提高成穗率,提高水稻产量,增加经济效益。
[ rice- duck Objective farming ] It aims to increase by further exploring the benefit of using no-tillage paddy field to conduct integrated its technology, and provide scientific ＆ theoretical basis for widespread application. [ Result ] The total output value of the duck-breeding area is ￥ 37,982/hm2, which increases by ￥ 15,911 more than the contrast area of ￥ 22,071/hm2, with a growth rate of 72. 1%; the net income of the duck-breeding area is ￥17,052. 5/hm2 ,which increases by ￥9,296/hm2 more than the contrast area of ￥7,756. 5/hm2 ,with a growth rate of 140. 5%. Meanwhile,it can help to achieve the goal of ecological and environmental protection. [ Conclusion ] Duck raising in no- tillage paddy field benefits：lessening weeds in paddy fields;inhibiting growth of rice diseases and insect pests, especially rice planthopper ＆ banded sclerotial blight ; reducing ineffective tillers of rice ; improving ear-bearing tiller rate ; increasing rice yield and economic efficiency.
