摘要:: 在渭北旱源的3个红富士果园，进行N、P、K化肥试验，结果表明：随N肥用量增加。新生枝长度、叶厚、叶重、茎粗和叶片含N量不断提高。K肥对增加茎粗，P肥对提高叶片含P量有显着作用。在供试条件下，N肥的效应函数是：y=5.6+40.5N-22.0N²，最佳施氮量为0.89kg/株。平均每kgK₂O增产苹果4.2kg，K₂O的较适宜施用量是0.4kg/株。每株施用0.9kgP₂O或0.45kgP₂O₅和0.52kgK₂O配合施用，比单施0.45kgP₂O₅有显着的增产效果；P、K肥再加倍施用测减产。

Abstract:: Experiments of N, P and K fertilizers were laid out in 3 Fuji apple orchards in Weibei rainfed highland.Results how that with the increase in N application, there are continuing increases in the lengty of newly-grow branches, leaf thickness, leaf weight, stem diameter as well as N content in leaves.There are significant positive effects of K fertilizers on stem diameter and of P ferilizers on P content on leaves.In experimental condition the function of N fertilizer effect is y=5.6+4.0N-22.0N² and the optimum N application is 0,89kg/tree.1 kg K₂O brings an average increase of 4.2kg apples and the more optimum K₂O application is 0.4kg/tree.1 kg K₂O brings an average obvious when 0.9kg P₂O₅ or 0.45kg P₂O₅ and 0.52kg K₂O are given to each tree each tree than only 0.45 kg P₂O₅.However, yield decreases if P, K fertilizers double.
