【摘要】 该文介绍了一种在苹果示范园进行树下养鹅的模式,通过研究饲喂鹅的数量与果园草覆盖率的关系,得到最优的养鹅方式。结果表明:养鹅数量为45只/hm~2为最佳,既增加了养鹅收益,又减少了果园割草的支出,收益提高了5265元/hm~2。同时,连续3a树下养鹅后,土壤有机质及养分含量增加,苹果果重、硬度、可溶性固形物含量也有所提高。更多还原

【Abstract】 This paper introduces a model of raising goose under tree in Apple demonstration orchard,and gets the best way of raising goose by studying the relationship between the number of goose feeding and the coverage of orchard grass. The results showed that the optimum number of geese per hectare was 45 geese per hectare,which not only increased the profit of geese,but also reduced the expenditure of mowing grass in orchard,and increased the profit by 5265 yuan per hectare. At the same time,the content of soil organic matter and nutrients increased,and the weight,hardness and soluble solids content of apple fruit also increased after raising goose under tree for 3 years.更多还原
