天山、阿尔泰山不同草地类型草群养分评价

Tianshan Mountains,Altai Different Types of Grass Lawn Nutrient Evaluation Group

根据天山北坡和阿尔泰山南坡主要草地类型的分布特点,选择不同类型草地的典型分布区域布设监测样地,不同区域、不同类型草地草群营养成分分析结果显示:天山北坡山地草原类草地草群的粗蛋白含量最高,达到15.54%;亚高山类天然打草场次之,达14.26%;阿尔泰山山地草甸类草地草群的粗蛋白含量最高,达到14.62%;山地草甸草原类和高寒草甸类次之,分别为13.53%和13.14%;不同区域夏季放牧草场草群的粗蛋白含量一般都高于其他季节草场;天山北坡与阿尔泰山相同类型草地草群的养分含量具有一定差异;不同放牧利用制度对草场植被养分含量有所影响。

According to the Tianshan Mountains and the distribution of Altai southern slope major grassland types, select Typical regional distribution of different types of grass laid monitoring plots, different areas of different types of nutrients meadow grass group analysis showed： northern slope of Tianshan Mountain steppe meadow grass group crude protein content of the highest, reaching 15.54%;subalpine meadows natural fight followed, up 14.26 percent; highest crude protein content of Altai mountain meadow, grass group reached14.62%; mountain meadow steppe and alpine meadow category, followed respectively 13.53% and 13.14%; different regions of summer grazing pasture grass populations crude protein content is generally higher than in other seasons pasture; nutrient content of the Tianshan Mountains and the Altai same type of turf grass group has some differences; different grazing systems have an impact on the nutrient content of grassland vegetation.
