And the pollution caused by human activities to the soil needs urgent treatment. Nickel is an essential trace element in human beings, but excessive amounts of nickel are toxic. At present, the pollution of nickel in soil is very serious in our country. The soil pollution prevention action plan should be responded to as soon as possible to improve nickel contamination in soil. This paper summarized the basic principle of the microbe-assisted phytoremediation, and the effects of adding microorganisms in nickel contaminated soil on plant growth conditions, available Ni content and plants on the absorption of nickel. It was of great significance to find suitable plants and microorganisms for remediation of nickel contaminated soil. And it was expected that the effect of organic acids on plant-microbe combined repair. And establishing the PGPB Library and looking for our hyper accumulator are also the focus of research. 查看全文  查看/发表评论  下载PDF阅读器
