摘要： 为了解矮化苹果营养状况及合理施肥，对盛果期矮化金红(GM256中间砧)不同施肥量、不同树势叶片及土壤的矿质营养状况进行了分析。结果表明：不同树势和不同施肥处理的叶片均表现为氮适量，磷严重不足，钾缺乏，营养失调；叶片中钙、镁、铁、锌、铜、硼适量或富足，钼严重不足。综合土壤和叶片的营养状况，建议生产中氮、磷、钾三要素施肥比例以2∶1.5∶1.5～2为宜。

Abstract: The nutrition of leaves and soils with different fertilizer norm and different tree vigour in full fruit period of Jinhong apple(GM256intermediate stock)were studied in order to realize nutrition condition and fertilizing.Results showed:the nutrition of leaves with different fert ilizer norm and different tree vigour were both N content moderate,P and K content insufficient,N,P,K content nutritional disorder;Ca,Mg,Fe,Zn,Cu,B content moderate or enough,Mo content insufficient.The results suggested that the fertilizer ratio of N,P,K content was 2 1.5 1.5-2.
