摘要
麻类作物是人类种植历史最为悠久的作物种类之一,其种类较多,适应性较广,抗逆性以及重金属吸收能力较强。文章综述了重金属对麻类作物生长的影响,以及麻类作物对重金属的吸收能力、重金属在植株体内的分布、重金属胁迫下植株的生理变化等方面的研究结果,总结了麻类作物在耕地重金属污染修复利用的前景。笔者认为麻类作物是比较理想的重金属污染耕地修复作物。
The bast and leaf fiber crop is one of the oldest crops planted by human beings. They have rich species,wide adaptability,strong resistance to adversity and heavy metal absorption ability. In this paper,it is reviewed the effects of heavy metals on the growth of bast and leaf fiber crops,the absorption ability of heavy metals,the distribution of heavy metals in plants,the physiological changes of plants under heavy metal stress and so on. The prospect of bast and leaf fiber crops in remediation and its utilization of heavy metal pollution in soil is summarized. It is indicated that bast and leaf fiber crops are ideal crops for remediation of heavy metal contaminated farmland.
