| 摘 要： | 对我国东北农牧交错带内小尾寒羊集群放牧生态系统中5、7、9月钙、磷元素的营养状况进行了分析。结果表明:牧地土壤中钙、磷元素的总平均含量分别为1.46%、178.88μg/g;小尾寒羊2种主食牧草中钙、磷元素的总平均含量分别为0.39%、256.26μg/g;小尾寒羊羊毛中钙元素的总平均含量为2111.45μg/g;小尾寒羊羊血中钙、磷元素的总平均含量分别为69.65μg/g、10.21μg/g;小尾寒羊羊骨中钙、磷元素的总平均含量分别为4.44%、2.45%。据此认为,在该交错带集群放牧的小尾寒羊不会发生钙缺乏症或中毒病,但可能发生磷缺乏症。

| Abstract: | Nutrient situation of calcium and phosphorus of grazed codetta in crowd grazing system of Chinese northeast farming-Grazing enter-locking district were analyzed in May,July and September.The results showed that,the total average content of calcium and phosphorus in soil for grazing is 1.46% and 178.88 μg/g respectively;the total average content of calcium and phosphorus in two kinds of mainly grazed herbage is 0.39% and 256.26 μg/g respectively;the total average content of calcium in wool of grazed codettas is 2 111.45 μg/g;the total average content of calcium and phosphorus in blood of grazed codettas is 69.65 μg/g and 10.21 μg/g respectively;the total average content of calcium and phosphorus in bone of grazed codettas is 4.44% and 2.45%.According to above results,the crowd grazed codetta in this enter-locking district cannot suffer from the disease of calcium deficiency or calcium poisoning,but can suffer from the disease of phosphorus deficiency. |
