chinois. 通过叶面喷施、土施、土施结合叶面喷施等补钙措施,研究不同补钙方法及钙含量对葡萄果实养分和黑痘病抗性的效应。结果表明,各补钙处理都不同程度地提高了葡萄果实的钙含量,其中单项叶面补钙措施以1.00%（W/V）Ca（NO3）2处理为好,叶面复合补钙以1.25%（W/V）Ca（NO3）2加1.00%（W/V）CaCl2处理为好。相关性分析表明,葡萄果实中的钙含量与葡萄发病率、病情指数呈负相关,氮钙比与葡萄的发病率和病情指数呈正相关,即葡萄果实中钙含量的增加,能有效地增强对葡萄黑痘病的抗性。[著者文摘]

The method of application of Ca included leaves spraying, soil-fertilizing, and the colligation of leaf-spraying and soil-fertilizing. The results showed all the treatments increased more or less the content of Ca in the fruits. Of all the treatments,the spraying of 1.00% （W/V）Ca（ NO3 ）2 and 1.25% （W/V） Ca（NO3） 2 combined with 1.00% （W/V）CaCl2, could increase the content of Ca significantly. The content of Ca was negative correlation with the incidence of disease and the disease index in grape fruit. The N/Ca was positive correlation with the incidence of disease and the disease index in grape fruit. Ca could promote the grape fruit＇s resistance to S. ampulinum.
