The Effect of Polyacrylate Polymers on the Growth of Native Plant from Mine Soil Contaminated with Heavy Metal and Soil Quality
摘要
Abstract
The effects of 0.4% polyacrylate polymers on native plants from mine and quality of mine soil contaminated with heavy metal were studied by cylinder experiment. The results showed that the growth of four plant species were enhanced in the soil amended with 0.4% polymers and the total biomass of plant was 1.8 and 2.3 times that of control during two cycles. The growth of different plant species was different in the two cycles, Briza maxima{B. maxima) was greater in the spring-summer than autumn-winter, but its smaller biomass was not satisfied to supply sufficient covering on the soil. In spite of died in the spring-summer, Chaetopogon fasciculatus ( C. fasciculatus ) and Spergularia purpurea(S. purpurea) could be used in the remediation of this mine soil because of their great biomass in the autumn-winter. The soil enzymatic activities including dehydrogenase, acid-phosphatase, (3-glucosidase, protease, urease and cellulose were improved in the soil amended with 0.4% polymers, which was 3.4, 2.2~2.5,3.1~2.5,3.6~3.0,14.9~2.7 and 1.8~2.3 times that of control respectively. We also found that there was significant correlation between the growth of different plant species and soil pH and soil enzymatic activities, significant correlations between soil pH, C. fasciculatus ,soil protease and cellulose(r>0.60) and between B. maxima and p-glucosidase(r=0.82).关键词
