辽中地区稻鸭共作模式效益分析

Benefit Analysis of Rice-duck Intergrowth Model in Liaozhong Area

为探讨稻鸭共作模式在辽中地区的应用效果及效益,采用对比试验的方法,研究稻鸭共作模式对水稻穗部性状及产量、稻鸭体重的影响。试验结果表明:与对照区相比,稻鸭共作区的千粒质量高1.59 g,稻穗实粒数多49.5粒,有效穗数多18穗,产量也相对提高62 kg/667 m2;稻鸭在3周龄体重增加明显,超过理论值的最高值,且7周龄和9周龄的体重均在理论值的上限水平。

In order to explore the effect and benefit of rice duck farming model in Liaozhong area, the comparison method was adopted to study the effect of the rice duck farming mode on panicle characters yield of rice, and rice duck weight. The test results show that com-pared with the control area, thousand grain weight in rice duck farming area is 1.59 g higher, the rice panicle has 49.5 grains added, with 18 more productive ears, yield is 62 kg/667 m2 higher; rice duck weight increased significantly at 3 weeks of age, more than the maximum theoretical value, and weight are at the 7 weeks of age and 9 weeks of age are both at the upper limit of the theoretical value.
