Abstract:

The application effect of silicon fertilizer and calcium fertilizer on Korla fragrant pear was studied by field plot experiments. The results showed that compared with the control, five treatments all improved the fruit weight, fruit firmness, Vc content and soluble solids content of the Korla fragrant pear, and the content of titratable acid were all lower than that of control except for spraying calcium fertilizer and silicon fertilizer at the young and expanding stage, but the effect was small. Among the treatments, the effect of spraying calcium fertilizer combined soil application of silicon fertilizer was most remarkable in improving fruit weight, fruit firmness, Vc content and soluble solids content, which increased by 14.51%, 10.97%, 51.61% and 8.05% respectively compared with those of control, and the differences was all significant. Therefore, silicon and calcium fertilizer application has significant effect on both fruit quality and yield of Korla fragrant pear.

Key words: Korla fragrant pear, silicon fertilizer, calcium fertilizer, fruit quality
