soil dispersion

Detergency: The process by which soil is dispersion.

清净: 土壤是散布的过程.

The results indicate that the inial soil water content and the manner of water supply affect the dispersion coefficient deeply, but the manner of fertilizer supply does not affect it.

研究结果表明：土壤初始含水量、灌水方式对非饱和土壤水动力弥散系数影响大，而加肥方式对土壤水动力弥散系数影响小。
