不同亚麻品种(系)对土壤重金属镉吸收的比较研究
Comparative Study on the Absorption of Heavy Metal Cadmium in the Soil by Different Flax Varieties
摘要
Abstract
In order to explore the accumulation ability of flax(Linum usitatissimum L.)to heavy metal Cadmium(Cd)and the remediation effect of flax on low Cd-contaminated soil,the flax varieties of Zhongyama No.4,HLJ69,HLJ71 and L09-325 were chosen as test materials in this study.Through field experiments designed by random blocks,the capacity to accumulate Cd from soil of different flax varieties and different parts of flax plants was studied,and the changes of total Cd content in soil before flax plant-ing and after flax harvesting were compared and analyzed.The results showed that flax grew normally in low Cd-contaminated soil,and 4 different flax varieties had different accumulation capacity for Cd.The 4 varieties had significant difference of accumulation ability for Cd in the soil among the different varieties'stems,while no significant difference was observed in other parts,which may be due to the less tested varieties and their similar accumulation abilities for Cd.There are also significant differences in the accu-mulation ability of different parts of the same variety for heavy metal Cd in the soil.The roots have the highest accumulation,while the seeds have the least,which is beneficial to the utilization of seeds.Planting flax has a certain remediation effect on soil with low-excessive Cd.Using these 4 flax varieties in this experiment to remediate the low Cd-contaminated soil will just take about 3 years to reach the soil pollution risk control standards for agricultural soil.关键词
