摘要
在内蒙古锡林郭勒盟南部太仆寺旗研究不同放牧率对草地土壤物理化学性质的影响,研究结果表明:随着放牧率的增加,土壤0～10cm含水量减少,容重增加;土壤有机质、全磷和速效磷含量减少,全氮、碱解氮和速效钾含量增加。
The effects of different grazing intensity on soil physical and chemical properties were researched in Taipusi county of Inner Mongolia. The results showed that with the grazing intensity increased, the soil moisture content of O-lOcm was decreased, and the soil bulk was increased. Organic matter, total phosphorus and available phosphorus were also decreased, the total nitrogen, available nitrogen and available potassium were increased.
