How to calculate the synthesis operator is the key problem of controlled illumination prestack depth migration. In this paper the inverse time focusing operator is synthesized based on the traveltime calculation method of finite difference approach, and with this synthesis operator the authors calculate the focusing point controlled illumination prestack depth migration using Fourier finite difference.

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。
