'Our results demonstrate that the order of peach trees nutrient requirement is Mn, Fe, K, Ca, B, P, N, Mg, Zn and Cu, whereas the main lack of elements are Mn, Fe, K and Ca. On the basis of the results, a foliage fertilizer formula was posed for other peach orchards application in Beijing.%以大久保桃树为研究对象,采用叶片分析法对其进行营养综合诊断,分析树体营养亏缺情况.结果表明试验桃园桃树需肥顺序为Mn,Fe,K,Ca,B,P,N,Mg,Zn,Cu,主要缺乏元素为Mn,Fe,K,Ca.据此提出叶面肥配方,以供北京地区桃园参考施用.
