中文摘要
    通过分析施用四种铁肥的缺铁桃树土壤有效铁、土壤酶活性、细菌群落结构及叶片活性铁差异,结果表明不同铁肥对石灰性土壤中缺铁黄化桃树的矫正效果依次表现为EDDHA·Fe>Nutriagent>FeSO4>FeCl3>CK,且导致土壤有效铁、叶片活性铁、土壤转化酶、脲酶和蛋白酶活性及细菌群落结构发生较大变化;EDDHA·Fe、Nutriagent和FeSO4明显提高土壤中细菌的多样性和丰度,而叶片活性铁含量与土壤有效铁、转化酶、脲酶和蛋白酶活性有极显著相关性,但与细菌群落均匀度呈不显著的负相关。
英文摘要
    This paper reported the differences of the soil enzymatic activities, available iron contents, bacterial community structures and leaves’ active iron contents among the chlorotic peach trees applied with four ferric fertilizers. Results indicated that four ferric fertilizers showed a tendency as EDDHA·Fe>Nutriagent>FeSO4>FeCl3>CK in the corrective effects on iron chlorosis of peach trees grown on calcareous soil and can differently changed the contents of soil available iron and leaves’ active iron, activities of soil invertase, urease and protease, structures of soil bacterial communities in which the indexes of soil bacterial diversity and abundance were obviously promoted by EDDHA·Fe, Nutriagent and FeSO4. However, the contents of leaves’ active iron were most significantly correlated with the contents of soil available iron and activities of soil invertase, urease and protease while it was shown a non-significant negative correlation between the content of leaves’ active iron and the soil bacterial evenness.
