中文摘要：

以1a生＂嘎啦＂苹果为试材,研究了控释肥对幼果期果园土壤有机质、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：施肥处理降低了果园土壤的pH值和有机质含量,施用控释肥果园的pH值要高于普通复合肥;施用控释肥增加了土壤碱解氮含量,降低了速效磷的含量,速效钾变化不明显;施用控释肥提高了果园土壤中Fe、Cu和Zn的含量。

英文摘要：

Taking 1-year-old ＇Gala＇ apple as material, the effect of controlled release fertilizer on young orchard soil were investigated,including soil organic matter, pH value and the content of mineral elements such as N,P, K, Ca, Mg, Cu, Fe, Zn,Mn. The results showed that pH value and the content of organic matter reduced,and the pH value of the Orchard applying controlled-release fertilizer was higher than that applying common compound fertilizer. The soil nitrogen content increased,otherwise available phosphorus contents reduced followed with application of controlled release fertilizer,but the content of potassium didn＇t change significantly. Meanwhile,the content of Fe, Cu and Zn increased followed with the application.
