Abstract: 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.
