摘要： 试验结果表明：钾肥施用量对葡萄产量影响比较大，而且二者之间具有良好的数学模型：y=1887.4+97.6K-3.98K2；在本试验条件下，葡萄施肥以氮钾配比16:12比较适宜。在田间施肥时，氮钾的合理配比依据不同的葡萄品种和土壤肥力进行适当调整。

Abstract: On the basis of the results from the field experiments we came to reach the conclusion that potash had very significant effect on the yield of grape, moreover there was the well-simulated mathematical model between them：y=1887.4+97.6K-3.98K2; the preferable ratio of N to K2O was 16 to 12. The rational fertilizers combination should be appropriately adjusted according to the different grape varieties and soil fertility conditions when applying fertilizers.
