稻鸭共栖试验研究

Experiment on Rice-Duck Intergrowth

通过稻鸭共栖种养结合模式和常规种稻对比试验研究,结果表明:稻鸭共栖中鸭子除了对矮慈姑和稻稗的防效很差外,对其他几种杂草的防效均和化学防治区相近;鸭子在田间活动能显著降低害虫基数并减轻危害程度;稻鸭共栖处理的水稻稻米品质好而且稻田鸭瘦肉率高,价格偏高。稻鸭共作可获得净利1 106元/667 m2,比常规稻作550元/667 m2高556元/667 m2。

The experiment was carried out to compare rice-duck intergrowth model with conventional rice planting model. The results showed that the control effect of weeds, except Sagittaria pygmaea and barnyard grass, in former model was comparable to chemical control; the activity of ducks could decrease pest insect size and alleviate the damage; the rice quality was good and lean meat rate of duck was high in rice-duck intergrowth model, in which the net benefit could reach 1 106 yuan/667 m^2, more than 556 yuan/667 m^2 in conventional model.
