摘要
基于大田土壤水分入渗试验,分析了相同土壤质地(壤土)条件下,有机质含量对大田土壤水分入渗能力的影响;研究了在土壤有机质含量水平相近条件下,土壤水分入渗能力对土壤结构、土壤质地的反应。研究表明:土壤有机质对大田土壤入渗能力的影响十分明显;土壤累积入渗量随着土壤有机质含量的增加而增加;在土壤有机质含量水平相近条件下,土壤入渗能力随土壤密实程度的增大而减小,土壤质地由重到轻,土壤入渗能力增加。研究结果对于指导大田地面灌溉具有重要意义。
Based on the water infiltration experiments into soils in field, the influences of organic matter content on cumulative infiltration, and the change of infiltration capacity with soil structure, soil texture under the same organic matter content were analyzed and discussed. The results indicated that infiltration capacity of field soils increased while the organic matter in soils increased; under same organic matter content, infiltration capacity of soils decreased while the density of soil increased and increased with soil texture changing from weighty to light. The result is of practical meaning in guiding the field irrigation.
