摘要
研究了下蜀黄土母质发育的４种粘盘黄褐土６个土壤的水分特性，结果表明，死黄土、马肝土持水量最高，其次为黄白土，白土持水量最低，土壤的持水量与其粘粒关系密切。马肝土、黄白土的土壤水分有效性较高，供水性能较好，抗旱性能较强；死黄土、白土的土壤水分有效性较低，供水性能较差，抗旱性能较弱。土壤的有效水含量及供水性能与土壤有机质、结构状况关系密切。
The water characteristics of six clay pan
yellowcinnamon soils in Hefei area was studied.The results showed that:in waterholding
capacity, hard yellow soil and magan soil was the highest,yellowwhite soil the second,and
white soil the lowest.Waterholding capacity of soil had a close relationship with their clay
content.The high available water capacity in magan soil and yellowwhite soil gave them a good
antidrought capacity,while the low available water capacity in hard yellow soil and white soil
resulted in a bad antidrought capacity.The available watercapacity was mainly determined by
content of soil organic matter and soil structure.
