中文摘要：

为了探讨氮肥不同施肥深度和距干距离对葡萄叶柄硝态氮含量及果实品质的影响，以嫁接在不同砧木1103P和S04上的桑娇维赛（VitisviniferaCV．Sangiovese）为试材，进行了试验。结果表明：叶柄硝态氮含量均以在砧木根主体分布区施肥含量的较高；1103P根系分布深而窄，叶柄硝态氮含量较高的施肥组合为深20～30cm，距干40～60cm；S04根系分布浅而广，叶柄硝态氮含量较高的施肥组合为深10～20cm，距干40～80cm。表面撒施肥料损失大，肥效期短；行中间开沟施肥的效果最差。尿素适当深施可以提高果粒重和可溶性固形物含量，S／1103P在深20～30cm，距干40～60cm组合处，与叶柄硝态氮高峰相吻合；而S／S04在深20cm，距干60cm处果粒重和可溶性固形物含量较高，与叶柄硝态氮高峰相此施肥深度增加。

英文摘要：

In order to discuss the effect of fertilization depth and the distance to trunk on the nitrate-N accumulation in vine petiole and fruit quality, Sangiovese grafted on 1103P and SO4 were used as materials, The results showed that nitrate-N accumulation in vine petiole was high when fertilizing in the root concentrated zone. The root distribution of 1103P was deep and narrow, and the optimal fertilization pattern was 20~30cm fertilization depth and 40-60cm distance to trunk; the root system distribution of SO4 was shallow and wide, and the optimal pattern was 10~20cm depth and 40~80cm distance to trunk. Fertilizing on the surface had a short fertilizer efficiency period and the worst fertilization pattern was fertilizing in the middle of rows. Fertilizing depth properly could improve fruit weight and soluble solid contents. The optimal combination of S/1103P was 20~30cm depth and 40-60cm distance to trunk, corresponding to the peak of petiole nitrate-N, while the optimal combination of S/SO4 was 20cm depth and 60cm distance to trunk, deeper than the peak.
