不同生产方式下肉鹅养殖场地的贡献及生产效果

为明确不同生产方式下肉鹅养殖场地空间转移动态和养殖效果,以及养殖场地对内鹅养殖的贡献,对传统草地养鹅和“农牧一体化”农田养殖方式进行对比研究.结果表明:肉鹅养殖场地存在明显的空间转移现象,不同处理下农田和草地对内鹅养殖的贡献率分别为74.49％和98.7％,农田在内鹅养殖中的贡献率虽然低于草地,但仍在肉鹅养殖中占据主要地位；农田养鹅处理的肉鹅出栏体重比草地养鹅处理的减少0.21 kg,与草地养鹅处理差异不显著(n=3,P＞0.05),而且达到了商品销售的体重要求；不同方式下的肉鹅养殖均取得较好的经济效益,但草地养鹅每只肉鹅的净收入高于农田养鹅收入14元.“农牧一体化”生产方式下的农田养鹅模式,能够完成肉鹅的整个商品化养殖过程并取得良好经济效果.

Contribution of goose feeding space and production effects on the different production modes

Dynamics of transference of feeding spaces,feeding effects and the contribution ratio of different feeding spaces for goose were compared to the research between different feeding modes.The results showed that the dynamics of transference of feeding spaces changed significantly,and the contribution ratio of cropland and grassland for goose was 74.49% and 98.71% respectively in different treatments.Cropland accounted for the main part in goose breeding though the contribution ratio of cropland was lower than that of grassland.Compared with the treatment of feeding on grassland,the goose weight for sale in the treatment of feeding on cropland decreased by 0.21 kg,which met the market requirement,and the differences about body weight of goose between the two treatments were not significant (n=3,P >0.05).Good economic benefits were achieved through the goose breeding under different production modes,and the net income of per goose in the treatment of feeding on grassland increased 14 yuan than that in the treatment of feeding on farmland.Therefore the feeding on farmland under the production mode of agro-pastoral integration could finish the whole commercialized course of goose feeding and get good economic effects.
