| 摘 要： | 天然针茅草地是形成我国中温型草原亚带的重要群体。4年定位研究表明，牧草生物产量与降水、气温呈正相关；降水受到欧亚大气环流和西风环流指数的制约。牧草粗蛋白质、粗脂肪、钙、磷含量呈“双峰”型的季节动态，是由于降水影响牧草生长发育节律所致。针茅草地均属NC营养型，适宜发展皮、肉、乳兼用家畜。

| Abstract: | The stipagobica Roshev land is very important part of forming midd-temperate zone in China.After studying in four years ,It shows the biological yield of the grass is direct proportion with precipitation and climate;The precipitation is affected by atomosphetive circulation of Asia-Europe and western wind circulation ,the grass contained crude protein,crude fat,calcium,phosphorus show double peaks seasonal change,which is caused by precipitation.The Stipagobica Roshev is NC nourishment,and suit to livestocks. |
