The invention discloses a
calcium fertilizer and an application thereof. The
calcium fertilizer contains water-soluble
calcium salt and a
plant-growth regulating agent substance. The
plant-growth regulating agent substance is amine hexanoate or salts thereof. Regional trials show that, when the calcium
fertilizer is sprayed on leaves, the occurrence rate of apple bitter pox
disease can be reduced from 27% to below 7%. Compared with simple
calcium supplementation products, the calcium fertilizer provided by the invention is advantaged in good
calcium supplementation effect and increased yield. The calcium fertilizer provided by the invention assists in promoting
plant absorption and transportation of calcium, such that the calcium fertilizer can effectively solve the physiological calcium deficiency problems of fruit trees and vegetables. The calcium fertilizer can also be used for controlling various physiological diseases caused by calcium deficiency, such as apple bitter pox
disease, pox blotch,
pear blackheart, peach crevice line
softening, dehiscent fruits of orange, litchi, longan, mango, dates, and watermelon fruit, umbilical rots of tomatoes and green peppers, cabbage dry heart, and other plant calcium deficiency diseases. With the calcium fertilizer provided by the invention,
calcium content in fruits can be improved, the yield can be improved, the fruit quality can be improved, and the storage life can be prolonged.
