Problems solved by technology

[0003] Existing calcium fertilizers mainly contain the following types: one, natural calcium supplements, including eggshells, quicklime, potassium-calcium fertilizer (obtained by mixing sintering and crushing of potassium ore powder and limestone powder in proportion), silicon-calcium fertilizer, etc. This kind of fertilizer has poor water solubility, and is generally applied to the soil, and is gradually decomposed and absorbed by the soil; second, calcium nitrate, calcium sulfate, calcium chloride, calcium dihydrogen phosphate and other synthetic inorganic salt calcium fertilizers, such calcium element plants The absorption is slow, and a large amount is wasted in the soil; third, organic calcium, which is composed of amino acids, citric acid, calcium lignosulfonate, etc., and inorganic calcium salts to obtain calcium fertilizer containing organic matter, which is mainly liquid and has good water solubility. It has the characteristics of high absorption and utilization rate, but the content of nutrient element calcium in this product is low, generally around 50-100g / L, and its main function is to supplement calcium element, its function is single, and the application amount of calcium fertilizer is high
At present, some hydrogel calcium fertilizer products imported from abroad contain a large number of crystalline particles, which is not conducive to the absorption of calcium by plants.

preparation example Construction

[0034] A method for preparing a functional high-calcium plant nutrient solution. The ingredients include molasses liquid, polypeptide, magnesium oxide and calcium salt. Using in-situ thickening effect, the macromolecular chain containing hydroxyl and carboxyl groups in the molasses liquid and the polypeptide molecule Molecular chains containing amino groups and carboxyl groups are combined with magnesium ions to form a complex centered on magnesium ions, and then a hydrogel solution with high viscosity is obtained through the hydrogen bond between the macromolecular complex and water. The process of magnesium oxide, molasses liquid and polypeptide reacting with magnesium oxide through the carboxyl group to form a complex is as follows, wherein the complex includes three structures:

[0036] Magnesium oxide, molasses liquid, and polypeptide are combined with magnesium ions through carboxyl groups to obtain a macromolecular hydrogel with a cross-linked structure, ther...

Embodiment 1

[0046] Mix and dissolve 0.5% magnesium oxide, 15% molasses and 3% polypeptide to obtain a hydrogel, then mix 60% calcium nitrate salt, 5% magnesium chloride and 3% magnesium nitrate salt, 1% glycine, 4% urea, 5% potassium nitrate and 2% potassium chloride salt, 1.5% trace elements, 0.1% plant regulator brassinolide, 0.9% Tween-80, etc. were added in sequence, stirred and dissolved to obtain dark brown viscous Thick liquid, that is, functional high calcium plant nutrient solution HCa-1.

Embodiment 2

[0048] 0.5% magnesium oxide, 16% molasses liquid and 4% polypeptide were mixed and dissolved to obtain a hydrogel, and then 58% calcium nitrate salt, 3% magnesium chloride salt and 5% magnesium nitrate salt, 2% glycine, 4% % urea, 5% potassium nitrate, 1.4% trace elements, 0.2% plant regulator brassinolide, 0.9% Tween-80, etc. were added in sequence, stirred and dissolved to obtain a dark brown viscous liquid, that is, functional High Calcium Plant Nutrient Solution HCa-2.

Abstract

A functional high-calcium plant nutrient solution, the ingredients include molasses liquid, polypeptide, magnesium oxide and calcium salt; the nutrient solution is a hydrogel solution containing cross-linked macromolecules, and there is no crystal precipitation; the calcium in the nutrient solution The content is above 190g / L. At the same time, the invention also provides a preparation method of the functional high-calcium plant nutrient solution. The invention utilizes the in-situ thickening effect to greatly increase the solubility of the solution to calcium ions, thereby obtaining a plant nutrient solution with high calcium content, supplementing the calcium element required by plants, promoting the absorption of calcium element by plants, and improving plant resistance. Cold, waterlogging, drought resistance, and promote crop growth. The indicator of the nutrient element calcium in the nutrient solution of the present invention can reach or even exceed the technical indicators of imported products, and the usage of the nutrient solution is low, the frequency of use is low, and it can increase the production of plants at the same time. The high-calcium plant nutrient solution has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of new materials for modern agriculture, in particular to a functional high-calcium plant nutrient solution and a preparation method thereof. Background technique [0002] With the rapid development of modern agriculture in our country, according to the needs of plant nutrients, the nutrients required for different stages of plant growth are developed in a targeted manner to achieve nutritional control of crops, fine fertilization, and reduce the use of agricultural fertilizers and pesticides. dependency. Calcium is the main component of plant cells, lack of calcium can easily cause plant physiological diseases, such as dry rot of cabbage and cabbage, navel rot of pepper and tomato, black heart of celery, etc. [0003] Existing calcium fertilizers mainly contain the following types: one, natural calcium supplements, including eggshells, quicklime, potassium-calcium fertilizer (obtained by mixing sintering a...
