稻鸭共栖试验研究

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。

Experiment on Rice-Duck Intergrowth

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 m2,more than 556 yuan/667 m2 in conventional model.
