| 摘 要： | 对高山草甸草地施氮５０ｋｇ／ｈｍ＾２和８０ｋｇ／ｈｍ＾２的试验结果：产草量提高１１０．２％和１７２．２７％，粗蛋白质产量提高１２６．３９％和１９６．１０％，但施氮对牧草其它营养成份无明显影响。实施本项技术措施后，能提高高山草甸冬春牧地的载畜量，具有显著的经济效益和生态效益。

| Abstract: | Results from nitrogen treatments in mountain meadow with the scale of 50kg/hm2 and 80 kg/hm2 showed that the herbage yield increased by 110.20%and 172.27%,re-sp. CP yield increased by 126.39%and 196.10%resp.But Nitrogen fertilization did not signifi-cantly affect other nutrients.Application of this skill can bring up to a significant economic and e-cological benefit by increasing the stock ing rate in mountain meadow in winter and spring. |
