Embodiment 1

[0021] Embodiment 1, prepare humic acid biological compound fertilizer as follows:

[0022] (1) Dilute 14 parts of nitric acid with water at a ratio of 1:200;

[0023] (2) drop into 5 parts of former powder of humic acid, add 16 parts of ammoniacal liquor after high-speed dispersion is uniform and cool;

[0024] (3) Nitrohumic acid after the treatment is uniformly mixed with 580 parts of urea and 25 parts of potassium dihydrogen phosphate;

[0025] (4) Stir at a constant temperature of 110 degrees Celsius for 45 minutes, cool, dry, pulverize and add 1 part of coagulant, and make 2-3 mm particles, the moisture content in the particles is 4%.

[0026] The temperature in the whole production process of the above steps (1) to (4) is controlled below 150 degrees Celsius to avoid biuret.

Embodiment 2

[0027] Embodiment 2, prepare humic acid biological compound fertilizer as follows:

[0028] (1) Dilute 25 parts of nitric acid with water at a ratio of 1:200;

[0029] (2) drop into 20 parts of former powder of humic acid, add 25 parts of ammoniacal liquor after high-speed dispersion is uniform and cool;

[0030] (3) Nitrohumic acid after the treatment is mixed with 620 parts of urea, 35 parts of potassium dihydrogen phosphate;

[0031] (4) Stir at a constant temperature of 110 degrees Celsius for 45 minutes, cool, dry, pulverize, add 5 parts of coagulant, and make 2-3mm granules with a moisture content of 6%.

[0032] The temperature in the whole production process of the above steps (1) to (4) is controlled below 150 degrees Celsius to avoid biuret.

Embodiment 3

[0033] Embodiment 3, prepare humic acid biological compound fertilizer as follows:

[0034] (1) Dilute 19 parts of nitric acid with water at a ratio of 1:200;

[0035] (2) drop into 10 parts of former powder of humic acid, add 20 parts of ammoniacal liquor after high-speed dispersion is uniform and cool;

[0036] (3) Evenly mix the treated nitrohumic acid with 600 parts of urea and 30 parts of potassium dihydrogen phosphate;

[0037] (4) Stir at a constant temperature of 110 degrees Celsius for 45 minutes, cool, dry, pulverize and add 1 part of coagulant, and make 2-3mm granules with a moisture content of 5%.

[0038] The temperature in the whole production process of the above steps (1) to (4) is controlled below 150 degrees Celsius to avoid biuret.

Abstract

The invention discloses a humic acid bio-compound fertilizer. The humic acid bio-compound fertilizer is prepared from the following raw materials in parts by weight: 14-25 parts of nitric acid, 16-25 parts of ammonia water, 25-35 parts of monopotassium phosphate, 580-620 parts of urea, 1-5 parts of a coagulating agent, and 5-20 parts of humic acid. According to the humic acid bio-compound fertilizer disclosed by the invention, urea reacts with humic acid under a certain condition to form a reasonable quantity of stable free radicals, and the activity of an enzyme in a plant body can be improved, so that the utilization rates of fertilizers such as a nitrogen fertilizer are increased, available nutrients in soil can be refined, absorption and utilization for all large and medium trace elements can be promoted, the damages of the fertilizers to soil can be reduced, and the hardening of the soil can be effectively prevented.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a humic acid biological compound fertilizer and a preparation method thereof. Background technique [0002] With the improvement of agricultural production conditions, the popularization and application of agricultural technology, and the implementation of policies to benefit farmers, farmers' planting awareness has been greatly improved. Agriculture in the 21st century, food safety is getting more and more attention from the government and the people, and the most important thing to pay attention to when advocating green and pollution-free products should be green planting. With the rapid development of China's chemical industry, the production and application of chemical fertilizers continue to increase. The increase in chemical fertilizers has undoubtedly played an important role in the development of agricultural production. problems such as environmental pollution are becoming ...
