土壤改良剂对酸性土壤改良的影响

S156; 通过对土壤物理性质、生化性质和玉米产量的测定,探讨了土壤改良剂不同施用量对酸性土壤改良效果.结果表明:施用改良剂后,各处理土壤容重下降幅度在5.34％～27.48％之间,pH提升幅度为7.2％～22.7％,有效改善了土壤物理性质;施用改良剂能促进土壤细菌、放线菌的繁殖,增强土壤纤维素酶、脲酶、过氧化氢酶和中性磷酸酶活性.施用改良剂200 g·m-2能有效改良土壤,显著促进玉米生长和增加玉米产量....

Bibliography:The effects of soil arneliomtor different application rote on acid soil physical properties, bio-chernical properties and maize yields were studied. The results showed that soil ameliorator decreased soil bulk density from 5.34 % to 27.48 %, increased soil pH from 7.2 % to 22.7 %, and improved soil physical properties. The quantifies of soil bacteria and acfinobacteria in ameliorator treatments were higher than those in control, and the activities of soil cellulose, urease, peroxidaze and neutral phoephataze presented the same trend. The results indica- ted that applying ameliorator 200 g · m-2 could effectively improve soil, significantly improve maize growth and increase maize yields.
