The lack of calcium in the peel of the grape fruit can cause the pulp to rot, brown, peel off the fruit and other undesirable phenomena. Therefore, spraying calcium on grapes before harvesting can increase the calcium content of grapes, increase the quality and yield of grapes, and increase economic efficiency.

According to the author's test, calcium spray can be applied to the grapes from 1 month to 10 days before harvest, and calcium nitrate should be suitable for spraying.
