Abstract

The invention discloses an organic calcium magnesium fertilizer and a preparation method thereof. The organic calcium magnesium fertilizer comprises the following components in parts by weight: 100 parts of chicken manure, 50-70 parts of 40% acrylamide water solution, 1.5-2.5 parts of sodium carbonate, 1.5-2.5 parts of sodium hydroxide, 15-25 parts of potassium chloride, 15-25 parts of magnesium sulfate, 25-35 parts of calcium sulfate, 7-15 parts of ammonium bicarbonate, 0.12-0.15 part of N, N-methylene diacrylamide, 0.15-0.22 part of complex cross-linking agent, and 0.05-0.15 part of initiator, wherein the concentration of the 40% acrylamide water solution is percentage concentration by weight. The organic calcium magnesium fertilizer is wide in property and use and is capable of repeatedly absorbing water and swelling in the soil and forcefully relieving the soil hardening; when the organic calcium magnesium fertilizer absorbs water to swell, the soil is loosen to ventilate, and the fertilizer is released while the water is also slowly released; when the fertilizer absorbs water again, the nutrient solution in the soil is absorbed and stored to relieve the loss of top dressing. Because the water and the fertilizer are repeatedly absorbed and slowly released, the utilization of the fertilizer by the crops is greatly increased and the yield is improved.

Description

[technical field] [0001] The invention relates to the field of fertilizers, in particular to an organic calcium-magnesium fertilizer and a preparation method thereof. [Background technique] [0002] Calcium is an indispensable nutrient element for the normal growth and development of crops. Rational use of calcium fertilizer, especially in the critical period of calcium-loving crops such as apples, tomatoes, and Chinese cabbage, can effectively prevent and treat crops caused by calcium deficiency. Physiological diseases lay the foundation for high yield and high quality. Calcium can be used as a bridge between the phosphate radical of phospholipid and the carboxyl group of protein in the biological membrane, thus maintaining the stability of the membrane structure. Calcium is an element that forms the cell wall, and the intercellular layer of the cell wall is composed of calcium pectate. When calcium is deficient, the formation of cell walls is hindered, which affects cell...
