Experimental results show that a soil substrate containing waste crumb rubber with a small grain diameter has the best average waterretainingcapacity and stronger waterretainingcapacity.
实验结果表明含废胶粒径小的土壤基质的平均保水力最好，具有较强的水分维持能力。

Though the wilting coefficient of soil tend to increase as waterretaining agents increased, the amplitude was low, so the soil available watercapacity augmented obviously.
土壤凋萎系数虽有增大趋势，但增幅很小，土壤有效水容量明显增大。

The effects of forest fires on soil separate coefficients, porosity, saturated water-retainingcapacity, available Mg, fine root significantly varied between the fire intensity.
