Embodiment 1

[0020] A composition of water-soluble calcium multi-element fertilizer, comprising: 25 parts of urea, 16 parts of potassium dihydrogen phosphate, 20 parts of potassium nitrate, 10 parts of calcium nitrate, 22 parts of ammonium sulfate, 2 parts of sodium gluconate and 5 parts of phosphoric acid. The pH of the reaction system of the composition is 3. This formulation produces a water-soluble fertilizer containing 2.5% water-soluble calcium.

Embodiment 2

[0022] A composition of water-soluble calcium multi-element fertilizer, comprising: 40 parts of urea, 40.9 parts of potassium nitrate, 10 parts of calcium nitrate, 0.1 part of diacetamide tetraacetate and 10 parts of phosphoric acid. The pH value of the reaction system of the composition is 3.5. This formulation produces a water-soluble fertilizer containing 2.5% water-soluble calcium.

Embodiment 3

[0024] A composition of water-soluble calcium multi-element fertilizer, comprising: 35 parts of urea, 30 parts of potassium sulfate, 10 parts of calcium sulfate, 20 parts of ammonium sulfate, 1 part of polyaspartate and 4 parts of sulfuric acid. The pH of the reaction system of the composition is 3.7. This formulation produces a 2.3% fertilizer with water soluble calcium.

Abstract

The invention discloses a water soluble calcium multi-element fertilizer composition. The water soluble calcium multi-element fertilizer composition is prepared from a calcium source with the solubility of 0.2% or above, mixed fertilizer and additives, the addition amount of the additives accounts for 0.1-5% of the total mass of the raw materials for producing the water soluble calcium multi-element fertilizer, the additives comprise a chelating agent and acid by the weight ratio of (0.1-1):(0.1-1), and the pH value of the composition reaction system is smaller than four. According to the water soluble calcium multi-element fertilizer composition, the fertilizer is prepared through the formula, effectiveness of calcium is improved, the production cost of adding water soluble calcium is reduced, and utilization of the chelating agent is reduced.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a composition of water-soluble calcium multi-element fertilizer. Background technique [0002] Calcium is an essential nutrient for plants. Calcium is beneficial to the growth of roots, the operation of metabolism and assimilation products in the body, and can enhance the stability of cell membranes. Calcium imbalance can lead to physiological disease. Calcium deficiency will cause meristems such as terminal buds, lateral buds, and root tips to rot, young leaves will be curled and deformed, and fruits will be stunted. Calcium nutrient is generally absorbed by the root system. After going up the plant body, it is no longer easy to move, especially it will not move backwards and down the root, and cannot be stored, accumulated and redistributed. Therefore, the continuous growth process of plants is also the process of continuous calcium supplementation. Only water-soluble calcium can...
