The contents of N, P, K in leaves were examined by regular leaf analysis. The results showed that the N content was higher in leaf blade than in leafstalk. N content in leaf was gradually reduced along with the vine growth. N, F, K fertilized at 20 to 40 cm soil layers significantly increased N content in leaf. But N content in leafstalk was less affected by N fertilization depth and growing season. P content was higher in leafstalk than in leaf blade. Less change of P content was noticed in leaf along with vine growth. However, N, P, K fertilized at 40 to 60 cm soil layers significantly promoted P in both leaf blade and leafstalk. K content in leafstalk was much higher than in leaf Wade. No obvious influence was noticed by fertilizing depth. But K content in leafstalk was significantly increased due to applied K fertilizer in late growing season.

结果表明，酿酒葡萄叶片中氮含量远高于叶柄，叶片中氮素含量随着生育期的延长逐渐降低，而叶柄中氮含量随施肥深度增加和生育期延长而产生的变化很小，40cm的施肥深度能显著增加叶片中氮素含量；叶柄磷素平均含量高于叶片，全生育期叶片磷含量变化很小，而施肥60cm深度显著促进了叶片和叶柄中磷含量的提高；叶柄中钾含量远高于叶片，施肥深度对叶柄和叶片中钾含量未产生明显影响，但生育后期追施钾肥显著提高叶片钾含量；施肥深度达到40cm时酿酒葡萄的产量最高，而60cm的施肥深度产量显著下降。
