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。

The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.
结果表明,长安南部黄土塬随着层位的降低,pH值有逐渐增大趋势,电导率和HCO(上标–下标 3)含量有逐渐减少的趋势;黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异,这与其理深、地层性质、溶滤与蒸发作用不同有关;长安南部少陵源黄土地下水元素含量较高,比呈酸性、元素含量低的翠华山泉水更适于饮用。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
