钙处理对黄花梨主要贮藏品质指标的影响

以黄花梨为试材,通过采前叶面喷施高活性钙镁肥、有机螯合钙以及叶面喷施结合根际灌施高活性钙镁肥、有机螯合钙等措施,探讨钙处理对黄花梨贮藏效果的影响.结果表明,黄花梨在16℃贮藏条件下,与对照相比,各施钙处理均极显著降低果实失水率、腐烂率,极显著增加果实硬度、总糖、总酸及可溶性固形物含量；除叶施高活性钙镁肥处理外,各施钙处理的Vc含量均显著高于对照.综合比较各钙处理的施用效果,采前叶施高活性钙镁肥处理的果实失水率及果实硬度极显著优于其他处理；叶施结合根施有机螯合钙处理的果实腐烂率极显著低于其他处理.

Effects of Calcium on Main Storage Quality Indices of Pyrus Pyrifolia var.Huanghua

Huanghua pear was used as materials to study the effects of calcium on its storage quality.The treatments were consisted of high active Ca and Mg、organic chelating calcium spraying as foliage fertilizer or with combination of foliage fertilizer and rhizosphere fertilizer before harvest.The results showed that,comparing to the contrast,all calcium treatments significantly reduced the water loss rate and rot rate,and significantly increased the fruit firmness and contents of total sugar,total acid and soluble solids of Huanghua pear when stored at 16℃.The Vc contents were significantly higher than the contrast except the treatment with high active Ca and Mg as foliage fertilizer.With comprehensive comparisons among all treatments,the treatment with high active Ca and Mg as foliage fertilizer pre-harvest had significantly better water loss rate and fruit firmness,and the treatment with organic chelating calcium as both foliage and rhizosphere fertilizer had significantly lower fruit rot rate than other treatments.
