Embodiment 1

[0016] Urea-formaldehyde humic acid organic fertilizer production process of the present invention, its steps are as follows:

[0017] A) Activation and fermentation treatment of organic raw materials; weathered coal and farmyard manure are mixed according to the weight and number ratio of 1-1.5:1-2 to obtain organic raw materials; the farmyard manure is cattle and sheep manure or cattle and sheep manure and plant straw particles mixture. Then add 0.1-0.2 parts by weight of ammonium bicarbonate and 0.03-0.05 parts by weight of monoammonium phosphate, after mixing evenly, pile up the fermentation tank for fermentation for one week; then turn the pile and spray mass ratio of 3-10% sodium hydroxide solution, hydrogen The amount of sodium oxide solution is 0.4-1.0% of the weight of the weathered coal, and it is evenly mixed and stacked for a week; then turn the pile and add the bacterial agent, and the amount of the bacterial agent is 0.05-0.3% of the weight of the organic raw mat...

Embodiment 2

[0023] After mixing 600kg of weathered coal and 800-1200kg of straw-containing cattle and sheep manure, add 80-120 kg of ammonium bicarbonate and 60-100 kg of monoammonium phosphate, pile it up at room temperature for a week, turn the pile and spray 18-24kg of mass The NaOH solution with a ratio of 10% is mixed evenly and stacked for a week; then turned over and added with 0.08-1.5kg of fermentation bacteria HM bacteria, stacked for 5-7 days; then at a temperature of 50-60°C, ventilated and fermented for 7 days, and obtained Maturing organic raw materials.

[0024] Take 1000 kg of mature organic raw materials and add 100 kg of inorganic raw materials containing nitrogen, phosphorus and potassium, wherein the inorganic raw materials include 40 kg of urea, 20 kg of potassium sulfate, and 20 kg of monoammonium phosphate. After the above materials are stirred and mixed evenly, they are crushed to 80 mesh. And sent to the granulation process and urea formaldehyde humic acid activat...

Abstract

The invention belongs to the technical field of production of compound fertilizers, relating to a production process of ureaformaldehyde humic acid organic fertilizer. The production process comprises the steps of activating and fermenting organic raw materials, preparing granulating base stock, granulating, processing granules, coating and the like, wherein humic acid and dung of cows and sheep containing straws are fermented together; the disadvantage that moisture in dung is high is solved; the balling rate is high since activated humic acid is used for granulating; the water content is low; coal consumption is low when the ureaformaldehyde humic acid organic fertilizer is dried; the temperature is low; beneficial microbial strains in the organic raw material are effectively preserved; the ureaformaldehyde humic acid organic fertilizer has ureaformaldehyde humic acid film-forming property and slow-release property; the ureaformaldehyde humic acid organic fertilizer produced by using the process disclosed by the invention has slow-release property and high hardness which is averagely 5-7N higher than that of the ordinary humic acid organic fertilizer, is hardly pulverized, and is low in production cost and strong in production continuity and operability.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production and relates to a production process of urea-formaldehyde humic acid organic fertilizer. Background technique [0002] Soil fertilizers are two basic elements of agricultural production. Since the 1980s, a large amount of chemical fertilizers have been applied to arable land in my country, resulting in land degradation, soil compaction, decline in soil fertility, reduction of organic matter and beneficial microorganisms, ecological imbalance of farmland, decline in product quality, and pollution of water resources and the environment to varying degrees. , making human health a potential threat. Researching and developing new, pollution-free organic fertilizers is an important topic for agricultural scientists. Biochemical organic fertilizer has become an important organic fertilizer. Humic acid has the characteristics of activating soil, promoting soil aggregates, increasin...
