重金属污染是一个世界范围内的严重问题,对生态环境和人类健康都有重大威胁。植物修复是一种新兴的去除土壤重金属污染的方式,如何提高植物在重金属污染土地上的生长状态是这一领域的研究热点。研究发现一些植物外生菌根真菌能非特异性地提高宿主对一些重金属的抗性,应用这一新技术有可能使一些有实际价值的植物在重金属污染土地上种植成为可能。本文综述这一领域最新的研究进展。
Heavy metal pollution is a serious problem in the world and poses a great threat to the ecological environment and human health. Phytoremediation is a new way to remove soil heavy metal pollution. How to improve the growth status of plants on the soil contaminated by heavy metals is a hot topic in this field. The study found that some plant ectomycorrhizal fungi can non-specifically increase host resistance to some heavy metals. The application of this new technology may make it possible for some plants of practical value to grow on areas contaminated by heavy metals. This article reviews the latest research advances in this area.
