Embodiment 1

[0028] The medium element water-soluble fertilizer of the present embodiment is made by the following steps:

[0029] 1) Weigh 85 parts of calcium ammonium nitrate, 4 parts of magnesium nitrate, 3 parts of boric acid, 7 parts of potassium fulvic acid, and 30 parts of water, mix and stir to form a uniform mixed solution;

[0030] 2) The mixed solution obtained in step 1) is evaporated and concentrated at a temperature of 70°C until a mother solution with a solid-to-liquid ratio of 1.15 is formed;

[0031] 3) The mother liquor obtained in step 2) is atomized at a temperature of 140° C. and sent to a spray granulator for granulation and drying;

[0032] 4) The granules obtained in step 3) are cooled to 20-35° C. by a cooler, the round granules are pulverized by a pulverizer, and the powder is sent to a tablet press to be compressed into a required shape, and then packaged to obtain a finished product.

Embodiment 2

[0034] The medium element water-soluble fertilizer of the present embodiment is made by the following steps:

[0035] 1) Weigh 87 parts of superphosphate, 2 parts of magnesium nitrate, 1.5 parts of magnesium chloride, 2.8 parts of boric acid, 5.2 parts of sodium humate, and 25 parts of water, mix and stir to form a uniform mixture;

[0036] 2) The mixed solution obtained in step 1) is evaporated and concentrated at a temperature of 80°C until a mother solution with a solid-to-liquid ratio of 1.1-1.2 is formed;

[0037] 3) The mother liquor obtained in step 2) is atomized at a temperature of 145° C. and sent to a spray granulator for granulation and drying;

[0038] 4) The granules obtained in step 3) are cooled to 30-35° C. by a cooler, the round granules are pulverized by a pulverizer, and the powder is sent to a tablet press to be compressed into a required shape, and then packaged to obtain a finished product.

Embodiment 3

[0040] The medium element water-soluble fertilizer of the present embodiment is made by the following steps:

[0041] 1) Weigh calcium ammonium nitrate, 80 parts of calcium nitrate, 4.2 parts of magnesium phosphate, 1.2 parts of borax, 8.5 parts of ammonium nitrohumate, and 35 parts of water, mix and stir to form a uniform mixed solution;

[0042] 2) The mixed solution obtained in step 1) is evaporated and concentrated at a temperature of 80°C until a mother solution with a solid-to-liquid ratio of 1.1-1.2 is formed;

[0043] 3) The mother liquor obtained in step 2) is atomized at a temperature of 140° C. and sent to a spray granulator for granulation and drying;

[0044] 4) The granules obtained in step 3) are cooled to 30-35° C. by a cooler, the round granules are pulverized by a pulverizer, and the powder is sent to a tablet press to be compressed into a required shape, and then packaged to obtain a finished product.

Abstract

Embodiments of the invention disclose a medium-element water-soluble fertilizer and a manufacturing method thereof, and relates to the technical field of fertilizers. The medium-element water-solublefertilizer is prepared from the following raw materials by weight: 80 to 90 parts of a water-soluble calcium fertilizer, 3 to 5 parts of a water-soluble magnesium fertilizer, 1 to 5 parts of a water-soluble boron fertilizer, 5 to 10 parts of a water-soluble humic acid fertilizer and 20 to 50 parts of water. The medium-element water-soluble fertilizer provided by the invention has the following advantages: the water-soluble calcium fertilizer, the water-soluble magnesium fertilizer, the water-soluble boron fertilizer and the water-soluble humic acid fertilizer are adopted as raw materials, andcomponents are reasonable in combination and have synergistic effect; the water-soluble humic acid fertilizer has the performances of resisting diseases, improving soil, reinforcing crop stress resistance, improving fertilizer efficiency, stimulating crop growth, etc., and can improve the absorption rate of elements like medium-element calcium and magnesium by combined application with the solublecalcium, magnesium and boron fertilizers, so well-developed root system and strong straw of a crop are realized, and lodging resistance and disease resistance of the crop can be significantly improved; thus, the purposes of yield increase and quality improvement are finally achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of fertilizers, and in particular to a medium element water-soluble fertilizer and a production method thereof. Background technique [0002] The middle element refers to the nutrient elements necessary for plant growth and development, which require moderate amounts, such as calcium, magnesium and other elements, which generally account for 0.2-1.0% of the dry weight. Calcium can improve the stability of plant cell membrane structure, and can also neutralize the acid produced in the process of plant metabolism, thereby eliminating the toxic effect of excessive organic acids on plant cells; magnesium is an important component of chlorophyll, and is also a variety of An important activator of enzymes. In addition, magnesium can also promote various metabolic activities in plants. [0003] In recent years, in order to pursue crop yields, people have used chemical fertilizers in large...
