摘要:
研究了腐植酸与丙烯酸、丙烯酰胺的接枝共聚物对赤红壤改良的作用.试验结果表明,该类共聚物显著改善了赤红壤的结构性能,大于0.25mm水稳性团粒结构由空白样的26.9%提高到43.7%～67.5%,渗透系数由1.8×10-5cm/s增加到最高的20.7×10-5cm/s,土壤容重由1.36g/cm3降低到1.26～1.02g/cm3.改良后的土壤毛管持水量、含水量明显增加.
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(×10-5 cm/s)was raised from 1.8 to 20.7(Max),the bulk density of the soil was lowered from 1.3 g/cm3 to 1.02 g/cm3(Min).The capillary water and the moisture of amended soil significantly increased.
