一、最大吸湿水最大吸湿水又称最大吸湿量或吸湿系数,它是风干土从近饱和水汽的空气中(相对湿度98％),吸收汽态水的最大量。土壤质地、腐殖质含量、土壤胶体种类对最大吸湿水的数值都有影响。最大吸湿水的数值可以估计凋萎湿度(凋萎湿度约等于最大吸湿水的1.4倍)。轻壤质黄土的最大吸湿水为4％,重壤质垆土则为7％左右。
First, the maximum moisture absorption Maximum moisture absorption, also known as maximum moisture absorption or moisture absorption coefficient, it is dry soil from the nearly saturated water vapor air (relative humidity 98%), the maximum absorption of water vapor. Soil texture, humus content, and soil colloid types all have effects on the maximum moisture content. The maximum hygroscopic water value can be estimated wilting humidity (wilting humidity is about equal to 1.4 times the maximum hygroscopic water). Light loess loess maximum moisture absorption of 4%, heavy loamy soil is about 7%.
