腐植酸接枝共聚物对赤红壤改良的研究
Study of Amelioration to Lateritic Red Soil
by Copolymer of Humic Acids Grafted Vinyl Monomer
摘要
Abstract
It was studied that graft copolymers of humic acids with acrylic acid and acrylamide affected on amelioration to the lateritic red soil.The results showed that copolymer significantly ameliorated the structure of the lateritic red soil,the production of ＞0.25 mm waterstable aggregates was increased from 26.9% to 67.5%(Max),the permeability coefficient of the soil(×10-5cm/s)was raised from 1.8 to 20.7(Max),the bulk density of the soil was lowered from 1.3g/cm3 to 1.02g/cm3(Min).The capillary water and the moisture of amended soil significantly increased.关键词
