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...
