摘要
以<0.01mm粘粒含量、毛管孔度、总孔隙度和有机质含量作为影响田间持水量的主要因子进行通径分析.结果表明,对田间持水量的直接影响以<0.01mm粘粒含量为最大,总孔隙度和有机质含量的共同作用对田间持水量的间接影响最为显著.
Taking clay particle (d < 0. 01 mm) , capillary porosity, total porosity, and the amount oforganic matter as main factors affecting field moisture capacity, we analysed them in terms ofpath analysis. The results showed: clay particle (d< 0. 01mm) had the greatest direct effect onfield moisture capacity; total porosity and the amount of organic matter had the most remarkleindirect effect on field moisture capacity.
