Embodiment 1

[0024] Example 1: Selection of aging time

[0025] 1. Preparation of nitrohumic acid compound fertilizer

[0026] (1) Activated brown coal: Put 5 parts of brown coal into the reactor, add 0.001 part of rhamnolipid, and then add 10 parts of dilute nitric acid with a concentration of 15%, turn on the stirring device of the reactor, and rotate at 16000~20000r / min , Control the temperature at 85~90℃, and carry out the oxidation reaction for 2h.

[0027] (2) Aging: After the oxidation reaction is completed, ammonium bicarbonate is added to adjust the pH to 6.5. Divide the activated lignite into 8 groups, and then carry out the aging reaction, aging respectively 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20h (respectively corresponding to groups 1-10), and obtain nitrate Base humic acid in each group.

[0028] (3) Preparation of fermentation filler: Dilute Bacillus amyloliquefaciens with water to an effective bacteria content of 1×10 7 With a cfu / ml bacterial suspension, inoculate 1 part of the bact...

Abstract

The invention belongs to the field of fertilizer, and particularly relates to high-activity nitro humic acid compound fertilizer and a preparation method thereof. The method comprises the preparationsteps that 5 to 7 parts of lignite are put into a reaction kettle; 0.001 part of rhamnolipid is added; then, dilute nitric acid is added for performing oxidizing reaction; then, ammonium bicarbonate is added; the pH is regulated to be 6 to 7; next, aging is performed for 4 to 6h to obtain nitro humic acid; meanwhile, bacillus amyloliquefaciens is diluted by water into a bacterium suspension with the effective bacterium content being 1*10<7>cfu / ml; the bacterium suspension is inoculated to the organic fertilizer; a fermentation filling material is prepared; the nitro humic acid, the fermentation filling material, ammonium nitrate, monoammonium phosphate and potassium sulphate are uniformly mixed, and are put into a pelletizer; steam is introduced, and sulfuric acid and ammonia gas are introduced; pelleting is performed to obtain the nitro humic acid compound fertilizer. The preparation method is simple; the lignite activation degree is high; the prepared compound fertilizer can effectively improve the crop yield; the hardening degree of the soil is effectively improved; the utilization rate of the fertilizer is improved.

Description

Technical field [0001] The invention belongs to the field of fertilizers, and specifically relates to a high-activity nitrohumic acid compound fertilizer and a preparation method thereof. Background technique [0002] In recent years, due to the extensive use of chemical fertilizers, my country's soil has become severely compacted, the ability to retain water and fertilizer has declined, and the growing environment for crops has continued to deteriorate. A large number of chemical fertilizers have doubled the cost of farming per mu, and the utilization rate of fertilizer efficiency has dropped sharply. The lost fertilizer also has a certain impact on the environment. [0003] Nitro humic acid is a kind of humic acid. It contains a certain amount of organic matter and has higher activity than other types of humic acid. It can improve soil physical and chemical properties, improve soil fertility, increase soil water retention capacity, promote crop photosynthesis, and improve Crop q...
