| Research Progress on Effects of Heavy Metal on Vegetable Production and Measures for Releasing Heavy Metal Stress |
| Heavy metals can affect vegetable growth and development，lead to decline of vegetable yield and quality，and finally，affect human health．This paper analyzed the effects of heavy metal on vegetable growth， physiological and biochemical activities from the respects of water metabolism，photosynthesis，respiration，anti-oxidase activity，ascorbic acid，glutathione，phytochelatins and other mineral elements absorption．The
paper also expounded the accumulation mechanism of heavy metals in different vegetable crops，varieties and vegetable organs，and summarized effective measures to alleviate soil heavy metal pollution．Besides，the paper suggested to carry out the following studies on： heavy metal accumulation differences in different vegetable varieties and species，screen and selection of vegetable species and varieties with low level heavy metal accumulation，
development of effective measures to relieve soil heavy metal pollution，so as to ensure safe vegetable production. |
