It can be carried out from 1 month to 10 days before harvesting, and it is advisable to spray calcium nitrate. Calcium is sprayed during the berry phase and is more easily absorbed. The spray concentration is preferably 1%. Spraying 10 days before harvesting, the concentration should be 1.5%. Spraying calcium fertilizer on grape leaves should be carried out before 10 o'clock in the morning and in the evening. On sunny days with high temperature and dryness, the spraying concentration should be smaller. If it rains within 8 hours after spraying, it should be sprayed again after the rain. .

Foliar application of calcium nitrate grape quality can be improved
It is currently in the grape harvest season, and the farmers are busy in the present year. Relevant experts said that proper application of calcium nitrate before grape harvesting can significantly improve the quality of the grapes. Anyone who has had planting experience knows that the lack of calcium in the fruit of the grape will cause the fruit to rot, brown, and the fruit to break away from the ear. Therefore, spraying calcium fertilizer on the grapes before harvesting can increase the calcium content of the grapes, improve the quality and yield of the grapes, and increase economic benefits.
