【摘要】 用张力计法测量了黄白土的持水特性及施用有机物料对其保水和供水性能的影响。结果表明 :(1 )在张力计测定范围内 ,黄白土土壤水吸力与含水量之间表现出显著的线性相关。(2 )施用有机物料 ,可以提高土壤的保水性能。其中施用牛粪的效果要优于麦秸。施用有机物料 ,还可以提高土壤速效水的上限 ,降低速效水的下限 ,提高速效水的含量 ,增强土壤水的有效性

【Abstract】 The main objectives were to study the property of holding water of yellow white soil and the effects of applying organic matter on its holding and supplying water by tensiometer. The results of study demonstrated that:(1) In range of tensiometer measurement, there was a kind of obvious linear relationship between soil water suction and content of the yellow white soil; (2) The organic matter can improve the property of soil holding water, and the effect of cow dung is better than wheat straw. And applying organic manure could also improve the upper limit of soil available water, cut down the lower limit, raise the content of soil available water and strengthen the available property of soil water.
