重金属污染对枸杞生长及品质影响的研究进展

Research Progress on the Effects of Heavy Metal Pollution on the Growth and Quality of Lycium barbarum

近年来随着工业快速发展,工业废弃物排放、污水灌溉等由此引起的土壤重金属污染,使作物的生长发育及品质受到影响已成为农业清洁化生产的瓶颈。枸杞因可以增强人体免疫力、抗衰老等功效是一种药食同源的营养保健品和中药材,其质量和安全问题备受人们的关注。国内研究多集中于枸杞重金属元素来源分析、测定和污染现状调查等方面,关于重金属污染对枸杞的影响研究不多。土壤中的重金属会通过根系的吸收作用转移到枸杞体内,并通过影响枸杞的生理机能改变枸杞的生长发育和品质。但目前研究对重金属影响枸杞生长发育的机制缺乏系统性研究。该研究在查阅国内外相关文献的基础上,系统总结重金属对枸杞生长过程中的生理生化影响规律,明确重金属对枸杞生长发育及品质影响的生理机制,以期为枸杞清洁化栽培提供参考依据。

In recent years with the rapid development of industry,industrial waste discharge,sewage irrigation and other resulting heavy metal pollution of the soil,so that the growth and development of crops and the quality of the impact has become a bottleneck in the cleaner production of agriculture.Lycium barbarum because it can enhance human immunity,anti-aging and other effects is a kind of medicine and food nutritional health care products and Chinese herbal medicine,its quality and safety issues doubly people′s attention.Domestic research is mostly focused on wolfberry yield and quality cultivation and regulation,about heavy metal pollution on wolfberry impact research is not much.Heavy metals in the soil will be transferred to Lycium barbarum through the absorption of the root system and change the growth,development and quality of Lycium barbarum by affecting the physiological function of Lycium barbarum.However,current research lacks systematic study on the mechanism of heavy metals affecting the growth and development of Lycium barbarum.In this study,on the basis of reviewing relevant literature at home and abroad,we systematically summarized the physiological and biochemical effects of heavy metals on the growth process of Lycium barbarum,and made clear the physiological mechanism of the effects of heavy metals on the growth and development of Lycium barbarum and its quality,in order to provide reference for the cultivation of Lycium barbarum in a clean way.
