| 摘 要： | 对红壤地区玄武岩母质发育的红粘泥、第四纪古红土发育的黄筋泥以及与黄筋泥交叉分布的红砂土等 3种土壤在不同利用条件下的持水、供水特征进行研究 ,结果表明 ,土壤持水和供水的总体特征主要受土壤母质的控制 ;3种土壤对植物的最大有效水分含量差异明显 ,并且土壤种类之间的差异大于同一土壤不同利用方式下的差异 ;土壤利用方式的不同则使低吸力段水分状况存在明显差异 ,从而改变其旱作土壤的通气状况

Differences of Soil Water Characteristics in Three Soils Developed from Different Parent Materials in Red Soil Region |
| |
| Abstract: | Studies on soil water holding capacity and soil water supplying capacity of three soils originated from different parent materials, which are called Hongnianni ,Huangjinni,and hongshatu in Chinese, under different utilization styles showed that the general characters of soil water holding and soil water supplying are mainly governed by soil parent material. There are obviously differences of the plant effective soil water content among three soils, and the differences among soils were much more than that among utilization styles. The differences of soil utilization styles change the soil water characters in the low suction stage, and then improved the soil air conditions. |
