摘　　要： 营养型土壤改良剂施入3种不同理化性状和不同肥力水平的酸性土壤进行恒温培养,20和40d后,测定土壤的pH值以及交换性酸总量、H+、K+、Na+含量.试验结果表明,营养型土壤改良剂提高了土壤的pH值,降低了土壤中交换性H+和Al3+含量.说明营养型土壤改良剂对酸性土壤具有明显的改良作用. Nutritive soil modifier was applied to three kinds of acid soil which are different in character and fertility. An indoor soil incubation experiment was conducted and soil pH, exchangeable H+, Al3+ were analysized after 20 days and 40 days respectivly. The result indicated that pH was increased and exchangeable H+, Al3+ were decreased in soil. In conclusion, nutritive soil modifier can meliorate acid soil.
