Abstract

The present invention discloses one kind of calcium fertilizer and its application. The calcium fertilizer contains water soluble calcium salt and plant growth promoting matter alpha-naphthylacetic acid or water soluble sodium alpha-naphthylacetate as well as stretching agent. The calcium fertilizer has excellent calcium replenishing effect and low cost. It is applied to fruit trees and vegetable to prevent and control plant diseases caused by calcium deficiency, raise yield, improve quality of product.

Description

technical field [0001] The invention relates to a plant fertilizer and its application, in particular to a calcium fertilizer and its application. Background technique [0002] Calcium deficiency in crops generally occurs in our country. Calcium is transported in plants with transpiration flow. The transpiration intensity of fruits and the competition for calcium are much smaller than that of leaves, resulting in calcium deficiency in fruits (bagged fruits exacerbate calcium deficiency), thus Cause calcium deficiency physiological diseases such as apple bitter pit disease, water core disease, peach fruit suture softening, pear black heart disease, kiwi fruit early ripening and easy softness, orange, litchi, longan, mango fruit cracking, tomato navel rot, sweet pepper tip rot, Cucumber bending and Chinese cabbage dry heartburn (caused by the low transpiration intensity of Chinese cabbage heart leaves and weak competition for calcium), etc., seriously affect the yield, quality...
