针对苏打碱土碱性强、渗透性弱的特点,本文研究了不同用量MM改良剂和JD改良剂对大安市不同土层苏打草甸碱土渗透性的影响。结果表明,MM改良剂效果高于JD改良剂;MM改良剂对表层土(0~20 cm)的影响最大。土壤渗透系数随着改良剂施入量增加有明显增加。
In view of the strong alkaline and weak permeability of soda ash, this paper studied the effects of different amount of MM improver and JD improver on the permeability of alkaline earth in sodic meadow in Daan city. The results showed that the effect of MM modifier was better than that of JD modifier. The effect of MM modifier on surface soil (0 ~ 20 cm) was greatest. Soil permeability coefficient increased significantly with the increasing amount of modifier.
