稻鸭共作鸭放养密度及经济效益研究

Economic benefit of appropriate duck stocking density in rice-duck co-farming

通过高邮鸭和绍兴鸭的稻田放养试验,获得不同品种在稻鸭共作模式中适宜的放养密度,以及常规稻作、稻鸭共作的经济效益分析。结果表明:放养密度越小,收捕时鸭平均体重越大。放养密度越大,收捕时每公顷产鸭总重越大。稻鸭共作的经济效益比常规稻作的经济效益要多4～5倍。高邮鸭50 m^2/只的稻鸭共作的经济效益比40 m^2/只、60 m^2/只稻鸭共作经济效益好。绍兴鸭40 m^2/只的稻鸭共作的经济效益比50 m^2/只,60 m^2/只经济效益好。高邮鸭稻鸭共作的经济效益比绍兴鸭稻鸭共作的经济效益略高。

Through experiments on the stocking of Gaoyou duck and Shaoxing duck in the rice field,we obtained the appropriate stocking density of the different ducks in the rice-duck co-farming and analyzed the economic benefits of conventional rice farming and rice-duck co-farming.The results showed that the lower stocking density led to the greater average bodyweight of the duck when they grew up,and the greater stocking density resulted in the higher total weight of all the ducks.The economic benefit of rice-duck co-farming was 4-5 times that of conventional rice farming.The economic benefit of the 50 square meters per duck stocking density was higher than that of the 40 square meters per duck and the 60 square meter per duck densities in the rice in co-farming with Gaoyou ducks.The economic benefit of the 40 square meters per duck stocking density was higher than that of the 50 square meters per duck and the 60 square meters per duck densities in the rice in co-farming with Shaoxing ducks.The economic benefit of raising Gaoyou duck was slightly higher than that of raising Shaoxing duck in rice-duck co-farming.
