摘要
以小白菜为试材,研究叶面喷施不同质量浓度的FeSO4 溶液对小白菜生长及吸Cd 量的影响。结果表明,低质量浓度的Fe(100～500 m g/L)可促进小白菜干物质的积累,Fe 的质量浓度达2 000 m g/L时则抑制其生长,Fe可减少小白菜对重金属Cd 的积累,提高小白菜品质。
ln order to study the effects of Fe on absorption of Cd and growth of vegetables,the leaves of pakchoi was sprayed with FeSO 4 solution in different concentrations.The results indicated that the lower concentration of Fe(100 to 500 mg/L)could promote the accumulation of dry matter in pakchoi.The growth of pakchoi was inhibited when the concentration of Fe was up to 2000 mg/L.The Fe could decrease the accumulation of Cd in pakchoi and improve its quality.
