Grape science supplements calcium to improve fruit quality

Calcium deficiency in grapes causes the leaves to curl in the opposite direction, the new leaves are dark green, the grape cracking rate is seriously increased, the physiological diseases such as grape shrinkage disease are aggravated, the fruit hardness is decreased, and the storability is poor. Therefore, calcium should be added in time during the growth of the grapes. Prime. The peak of calcium absorption in grapes is 1-3 weeks. In addition, the recent rainy and illuminating weather in Chongqing area should be carried out by the combination of spraying and soil application.

Spraying calcium fertilizer should be carried out during the expansion period of young fruit, that is, 1 week after the flowering to the hard core stage, continuous use 2-3 times, interval 7-10 days, calcium fertilizer requires water solubility, high concentration, easy to absorb such as chelated calcium Class, when spraying, choose no wind or less wind, spray on the back of the blade, focus on the young parts of the inflorescence and the ear. In order to increase the hardness and the marketability of the fruits, grapes are to be 10-15 days before spraying calcium fertilizers 1 times.

The soil lime can be sterilized not only by calcium supplementation, but also when it is cleared in the winter, and can be applied once again after the grape flower. Spread the lime cover between the rows of grapes, then plow it, using 50 kg.
