不同配置锦鸡儿防风固沙林土壤物理性质研究

Soil Physical Properties of Wind Protection and Sand Fixation Forest of Caragana sinica with Different Arrangements

采用环刀法和烘干法对科尔沁沙地不同配置模式锦鸡儿防风固沙林土壤物理性质进行了研究。结果表明：各配置模式容重均小于对照地,〉5-20cm尤为明显;不同配置模式土壤饱和持水量比对照地有较大提高;不同配置模式孔隙度均比对照地有较大改善,毛管孔隙度尤为明显。

Soil physical properties of Caragana sinica with different arrangements in Horqin Sandyland by using round knife method and oven drying method.Result shows that the soil bulk density of different modes of arrangements are less than that of contrast land,especially the soil bulk density abvoe 5-20 cm soil layer.Different distribution modes saturated soil water holding capacity has been greatly improved compared to the that of contrast land.Different modes of arrangements porosity have been greatly improved than that of contrast land,especially capillary porosity.
