摘要
本文以土壤水吸力测定仪为主要手段,对冀东几种土壤低吸力段不同吸力值与含水量的对应值进行了测定,得到了土壤容重、总孔度、毛管孔度、非毛管孔度、各级当量孔度和三相比等物理参数,从而看出它们对土壤肥力的影响。
By using soil moisture suction determining meter, the various suction values and coresponding values of water content in low suction range of several soils were determined. The physical parameters of soil bulk density, total porosity, capillary porosity, non-capillary porosity, various equivalent porosities and three phases ratio were obtained, from which the effects of them on soil fertility could be found.
