中文摘要：

采用苹果专用控释肥,设计不同试验处理,研究控释肥对果园土壤微生物,有机质,pH值和N、P、K、Ca、Mg、Cu、Fe、Zn、Mn等矿质元素含量的影响。结果表明,与普通复合肥相比,控释肥提高了果园土壤微生物量氮、微生物量碳和pH值,对有机质含量影响差异不明显;增加了土壤碱解氮、Fe和Zn含量,降低了土壤速效磷、交换性Ca、交换性Mg和Mn的含量,不同试验点速效钾和Cu的含量结果不一致;不同控释肥处理间大部分指标差异不明显。

英文摘要：

The effects of controlled release fertilizer on apple orchard was studied including soil microbes,organic matter,pH value,mineral elements contents such as N,P,K,Ca,Mg,Cu,Fe,Zn,Mn by the applying apple special controlled release fertilizer with different experiment＇s treatment.Results showed that,compared with treatments common compound fertilizer applied,application of controlled release fertilizer increased contents of soil microbial biomass nitrogen,soil microbial biomass carbon,pH value,soil available N,Fe and Zn,and decreased the contents of soil available P,soil exchangeable Ca,Mg and Mn,but there was no significant difference with content of organic matter.Contents of available potassium in different experimental sites were different,and most of the indicators of different treatments CRFs applied were not significant difference.
