摘要
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。
According to the characteristics of high degree of alkalinity and weak soil permeability, the effect of different levels of MM and JD modifier on the different layers＇ permeability of Da＇an soda meadow al- kaline soil was analyzed in the paper. The results showed that the effect of MM modifier was higher than JD modifier and MM modifier had the largest influence on the surface soil （0-20 cm）. The soil permeability coef- ficient had a significant increasing with increasing of modifier input.
