| 摘 要： | 采用半野外试验研究了聚丙烯酸盐对自然条件下矿区重金属污染土壤性质和矿区本地植株生长的影响.研究表明,0.4％的聚丙烯酸盐明显促进了4种污染矿区本地植物的生长,总生物量在两轮生长中分别是对照处理的1.8倍和2.3倍.不同植株对不同生长季节反映不同,其中Briza maxima(B.maxima)在春夏季节生长好于秋冬季节,但生物量不高,无法提供大面积覆盖.而Chaetopogon fasciculatus(C.fasciculatus)和Spergularia purpurea(S.purpurea)因其在秋冬季节生长明显好于春夏季节,尽管在春夏季节由于干旱而大量死亡,仍然可以大面积覆盖土壤,所以可尝试用于矿区土壤的植被固定.聚丙烯酸盐的应用显著改善了土壤脱氢酶、磷酸酶、蔗糖苷酶、蛋白酶、脲酶以及纤维素酶的活性.研究同时发现,不同种类植株的生长与土壤pH及土壤酶活性存在显著的相关关系,其中,土壤pH和C.fasciculatus的生长与土壤中蛋白酶和纤维素酶的活性正相关(r＞0.60),而Briza maxima的生长与蔗糖酶的活性正相关(r=0.82).

| 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,β-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 β-glucosidase(r=0.82). |
