摘要: 以3年生夏黑葡萄为试材, 分别喷施3种不同钙肥以探明钙处理对夏黑葡萄果实品质及贮藏性的影响。结果表明, 喷施钙肥能显著提高夏黑葡萄果实中可溶性固形物、总糖及维生素C含量;降低果实酸度;延长采后贮藏时间。各处理中以喷施流体钙效果最佳, 至试验结束日 (8月13日) , 流体钙处理较对照果肉硬度、可溶性固形物、总糖及VC含量分别提高9.25%、19.14%、20.70%和16.49 mg· (hmL) -1, 酸度较对照减少20.99%, 固酸比值提高12.02%, 表明该处理对提高果实品质作用明显。Abstract: Three-year-old Xiahei were used in studying for the effects of three different calcium fertilizers on the quality and storage property of the grapes.The results showed that applying calcium fertilizers increased the content of soluble solids, total sugar and vitamin C in the fruits significantly while decreased the fruit acidity;the duration of the fruit storage was prolonged.Comparing three fertilizers, spraying fluid fertilizer showed the best effects.By the end of the experiment date (August 13th) , the texture of fruit in hardness, the content of soluble solids, total sugar and vitamin C of the fruits from liquid calcium treatment were increased comparatively to those in the contrast for 9.25%, 19.14%, 20.70%and 16.49, respectively, with 20.99%reduction in acidity and 12.02%increase in solid acid ratio of treated fruits.The results showed that the treatment improved the fruit quality obviously.
