| 摘 要： | 以大田玉米地的土壤水分入渗跟踪试验为依据，分析讨论了土壤水分入渗的年变化特性，结果表明，给定土壤质地，土壤结构由疏松变密实，土壤水分入渗能力逐渐减小，土壤含水率的变化引起土壤水分入渗能力上下变幅。研究结论对于节水灌溉的灌水技术参数的确定和灌水效果的研究具有理论意义，对灌溉的用水管理具有实际意义。

| Abstract: | Based on soil water infiltration experiments in corn field, this paper analysed and discussed yearly change characteristics of soil water infiltration .The experimental results indicated that soil water infiltration features diminished increasingly in soil grade ,and had amplitude of variation in soil moisture with given soil texture. These results have theoretical value for ascertain of irrigation technique parameters and the study of irrigation effects and have practical value for water management with irrigation . |

| Keywords: | soil water infiltration soil grade soil moisture accumulation infiltration amount |
