摘  要：
通过比较分析深松与压实及对照处理棕壤农田土壤的硬度剖面分布和水分入渗曲线变化,研究不同耕作措施对土壤机械物理性质和通透性能的影响。结果表明:(1)深松和压实处理后,0~25 cm土层硬度大小顺序为压实>对照>深松,25~40 cm土层的硬度为深松>压实>对照;而这一处理效果随处理后时间的延长而逐渐减弱,但90天后0~25 cm土层处理间差异依然存在,而25~40 cm土层这一差异不明显;(2)菲利浦公式能较好地表达压实、深松和对照处理土壤水分入渗速率随时间的变化过程,且不同处理及各处理重复间的土壤入渗曲线变异性较大;(3)对各处理土壤入渗菲利浦公式做标定处理求得的代表性入渗曲线,其初始入渗速率大小顺序为深松>对照>压实,而稳定入渗速率则为对照>压实>深松处理;说明深松和压实对土壤入渗能力影响明显不同,深松不仅能提高前期土壤水入渗能力、还能抑制入渗后期的深层渗漏。

摘  要：
In order to investigate the influence of soil tillage management on soil mechanical physical characteristics and soil permeability, we studied soil strength profile and soil water infiltration curves in deep ripping, compaction and control treatment, respectively. The results showed that: 1) The values of soil strength decreased in the sequence of compaction > control > deep ripping at the depth of 0- 25 cm and deep ripping > compaction > control at the depth of 25- 40 cm. However, the influence of all treatments on soil strength weakened with time. 2) Although Philip equation fitted the infiltration curves well, the infiltration curves of the different treatment had large variation. 3)Philip's infiltration equations of three treatments were calibrated by using the calibration theory. The representative curves showed that deep ripping had the greatest initial infiltration rate, whilst control treatment had the intermediate one, and compaction had the lowest. The stable infiltration rate was in the order of control > compaction > deep ripping. The results implied that the influence of deep ripping and compaction on soil water infiltration was significantly different. Deep ripping not only improved the infiltration capacity, but also restrained the deep percolation.
