摘要
本文根据田间波涌灌溉的试验研究，论述了在间歇灌水条件下，土壤表面致密层的形成过程及发展规律，在此基础上，进一步讨论了致密层在改变土壤入渗特性，以及朝着有利于节水、提高灌水质量等方面的发展上所起的作用．
Based on the field experiments for surge flow irrigation,the law of the emergence and development of surface soil seal are discussed in this paper.The effect of soil sealing on soil infiltration characteristics,water saving and improvement of irrigation efficiency are further studied.
