tailieunhanh - The effect of microorganism fertilizer on the growth and Cu accumulation of lettuce (Lactuca sativa) grown on soil contaminated by Cu

This paper presents the experimental results of the effect of microorganism fertilizer (MF) on growth, yield and accumulation of Cu in lettuce grown on soil contaminated by Cu. The results show that applying MF on soil that has a Cu content of ppm has a positive affect on the height, fresh weight, total chlorophyll content and catalase activity of lettuce grown on that soil. | JOURNAL OF SCIENCE OF HNUE DOI Chemical and Biological Sci. 2015 Vol. 60 No. 9 pp. 104-111 This paper is available online at http THE EFFECT OF MICROORGANISM FERTILIZER ON THE GROWTH AND Cu ACCUMULATION OF LETTUCE Lactuca sativa GROWN ON SOIL CONTAMINATED BY Cu Tran Khanh Van and Pham Thi Hau Faculty of Biology Hanoi National University of Education Abstract. This paper presents the experimental results of the effect of microorganism fertilizer MF on growth yield and accumulation of Cu in lettuce grown on soil contaminated by Cu. The results show that applying MF on soil that has a Cu content of ppm has a positive affect on the height fresh weight total chlorophyll content and catalase activity of lettuce grown on that soil. The amount of Cu found in leaves of lettuce grown on soil treated with MF was significantly less than that of lettuce grown on soil which was not treated with MF. Therefore if lettuce was grown on soil contaminated with Cu the leaves of the lettuce would be safer to eat if that contaminated soil was treated with MF. Keywords copper accumulation lettuce microorganism fertilizer growth 1. Introduction Environmental pollution and especially heavy metal pollution are growing problems. Heavy metals that have polluted agricultural land used to grow vegetables are accumulating in the bodies of livestock and people who consume these vegetables and a variety of health problems have become apparent. Such soil pollution is the result of industrial operations which treat their waste poorly or not at all. Offenders include the mining industry businesses operating in industrial zones and family businesses in craft villages. The environmental pollution near industrial zones and craft villages has been bad and it is getting worse 1 2 . Farmers in these areas have only two choices continue to plant on their polluted soil or abandon their farm and move to an urban area. In their quest to maintain farm .
