Abstract
A pot experiment was adopted in greenhouse to study the influence intercropping wheat on Cd uptake of two cultivars of peanut under varied iron nutrition.The results showed that iron nutritional status had little influence on dry weight of two varieties peanuts.The highest level of available Cd content of rhizosphere soil in Baisha 1016and Huayu 20was found in intercropping system in iron-rich soil,and the content reached 0.27,0.31 mg/kg respectively.In monoculture system,difference in Cd content of two varieties peanuts shoot and root was not significant,but the content was higher than that in intercropping system.In intercropping system,comparing with iron-rich condition,Cd content in two varieties peanuts root under Fe deficiency condition decreased by 39.0% and 34.3%respectively.Iron nutritional status had little influence on Cd mobility in monoculture peanut.The migration rate of Cd in Baisha 1016and Huayu 20 significantly increased when intercropping wheat under Fe deficiency condition,and they increased 1.1times and 0.6times respectively.Wheat rhizosphere Cd content in intercropping system was less than that in monoculture system,the lowest Cd content in wheat roots was 7.92mg/kg under the condition of intercropping Huayu 20in Fe deficiency soil.In monoculture system,Cd accumulation in peanuts was less than the accumulation in wheat.The sequence of the ability of uptake Cd was Baisha 1016wheatHuayu 20.In intercropping and iron deficiency system,crops accumulated the least amount of Cd.The experimental results showed that the system of intercropping wheat and peanut could reduce the accumulation of Cd in the two crops,and reduce the risk of human intake of Cd.
