不同铁肥对缺铁桃树土壤酶活性与细菌群落结构的影响
Effects of different ferric fertilizers on soil enzymatic activities and bacterial community structure of chlorotic peach trees
摘要
Abstract
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 ,ac-tivities of soil invertase ,urease and protease ,structures of soil bacterial communities in which the inde-xes 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-signifi-cant negative correlation between the content of leaves' active iron and the soil bacterial evenness .关键词
