Method of making calcium fertilizer and effervescent tablet

Abstract

A method for making calcium fertilizer and an effervescent tablet is characterized in that: a calcium fertilizer base material is formed by calcium nitrate, gamma-polyglutamic acid raw powder and alpha-pimacol raw powder which are mixed according to a proportion of 300:3:1; according to weight percent, 30 to 80 percent of calcium fertilizer base material, 15 to 40 percent of potassium bicarbonate or potassium carbonate, 15 to 40 percent of citric acid and 1 to 3 percent of sodium dodecylsulphonate are respectively dried and mixed, and then are moistened by a small amount of anhydrous alcohol so as to be pressed into a fertilizer tablet. When alpha-pimacol and gamma-polyglutamic acid are added in, the calcium fertilizer is propitious to promote calcium absorption, and gamma-polyglutamic acid is also propitious to ensure that calcium ionic complex can be adhered to the surfaces of leaves and fruits; therefore, the calcium fertilizer is propitious to absorption and has quick returns, thereby increasing the content of calcium in fruits and vegetables and preventing diseases caused by calcium deficiency. The effervescent tablet made by the calcium fertilizer is easy to carry out dosing and has convenient transportation and use.

Description

A kind of calcium fertilizer and its effervescent tablet preparation method (1) Technical field The invention relates to a calcium fertilizer and a method for preparing an effervescent tablet thereof, belonging to the field of fertilizers and fertilizer processing. (2) Background technology Calcium is closely related to the normal metabolism of horticultural crops such as fruit trees and vegetables. So far, at least 40 kinds of physiological diseases have been known in fruit trees and vegetables, such as apple bitter bean disease, water core disease, cork spot disease, stalk rot of tomato and sweet pepper, cabbage Dry heartburn, sweet potato bud rot, etc., are all caused by calcium deficiency, which seriously affects the quality and yield of horticultural crops. However, in most cases, the soil is not deficient in calcium, and the lack of calcium in the fruit does not mean that the soil is deficient in calcium. The main reason is that the availability of calcium is low, an...
