摘要

研究了以腐植酸共聚物作为土壤结构改良剂改良赤红壤后对该土壤化学性能的影响。实验结果表明

改良后的土壤比表面积、电荷量、阳离子交换量随共聚物在土壤中施入量的增加而增大

土壤的酸性减弱

pH提高。共聚体系中丙烯酸组分投料比的增加对土壤比表面积的影响不同于对电荷量及阳离子交换量的影响。

Abstract

The effects of humic acid copolymers on chemical properties of the soil are studied.The experimental results showed that specific surface area

the charge amount and the cation exchange capacity of the soil increased with dose of the copolymers in the soil.The effect of acrylic acid amount of the copolymers on specific area was different from that on the charge amount and the cation exchange capacity of the soil.The pH of the soil amended was raised.
