Embodiment 1

[0023] A humic acid organic fertilizer containing multiple active groups is prepared from 10kg of straw, 25kg of waste fungal buds, 10kg of chicken manure, 15kg of pig manure, 30kg of cow manure and 5kg of active humic acid. Its preparation method is:

[0024] (1) Extracting active humic acid: the young lignite with 10% by weight of free humic acid is crushed through a 100 mesh sieve, mixed with water at a weight ratio of 1:10; continuously fed into the air, under the conditions of 240 ° C and normal pressure Stir and react at 2000rpm for 6 hours; then react for 15 hours at a temperature of 70°C and a pressure of 5 atmospheres; filter out the precipitate with a 60-mesh filter, and the obtained clear liquid is active humic acid.

[0025](2) Weigh 10kg of straw, 25kg of waste fungus buds, 10kg of chicken manure, 15kg of pig manure, and 30kg of cow manure according to the weight ratio, mix and stir evenly, ferment at room temperature for 25 days, and use walking turning over ever...

Embodiment 2

[0028] A humic acid organic fertilizer containing multiple active groups is prepared from 15kg of straw, 20kg of waste fungus buds, 15kg of chicken manure, 10kg of pig manure, 40kg of cow dung and 10kg of active humic acid. Its preparation method is:

[0029] (1) Extracting active humic acid: the young lignite with 10% free humic acid by weight is crushed through a 200-mesh sieve, mixed with water at a weight ratio of 1:10; continuous air is introduced, under the condition of 240°C and normal pressure Stir and react at 3000rpm for 6 hours; then react for 19 hours at a temperature of 175°C and a pressure of 6 atmospheres; filter the precipitate with a 100-mesh filter, and the obtained clear liquid is active humic acid.

[0030] (2) Weigh 15kg of straw, 20kg of waste fungus buds, 15kg of chicken manure, 10kg of pig manure, and 40kg of cow manure according to the weight ratio, mix and stir evenly, ferment at room temperature for 30 days, and use walking turning over every 2 days ...

Embodiment 3

[0033] A humic acid organic fertilizer containing a variety of active groups is prepared from 12kg of straw, 23kg of spent fungus buds, 15kg of chicken manure, 15kg of pig manure, 35kg of cow manure and 8kg of active humic acid. Its preparation method is:

[0034] (1) extracting active humic acid: the young lignite with 10% free humic acid by weight is pulverized through a 150 mesh sieve, mixed with water at a weight ratio of 1:10; continuously fed with air, under the conditions of 220°C and normal pressure Stir and react at 1500rpm for 6 hours; then react for 18 hours at a temperature of 120°C and a pressure of 6 atmospheres; filter the precipitate with an 80-mesh filter, and the obtained clear liquid is active humic acid.

[0035] (2) Weigh 12kg of straw, 23kg of waste fungus buds, 15kg of chicken manure, 15kg of pig manure, and 35kg of cow manure according to the weight ratio, mix and stir evenly, ferment at room temperature for 28 days, and turn over every 2 days by walkin...

Abstract

The invention provides a humic acid organic fertilizer containing various active groups which is characterized in that the humic acid organic fertilizer is prepared from the following materials in parts by weight: 10-15 parts of straw, 20-25 parts of waste fungus bracts, 10-15 parts of chicken manure, 10-15 parts of pig manure, 30-40 parts of cow dung and 5-10 parts of active humic acid. The humic acid organic containing various active groups enables soil environment not to degenerate, enables soil to maintain persistent productivity, can recover the microorganism activity of soil, accelerates the mineralization and conversion of soil nutrients, is harmless, nontoxic and has no residue, and has no toxic and side effects on soil, plants and a human body.

Description

technical field [0001] The invention relates to a humic acid organic fertilizer containing multiple active groups and a preparation method thereof. Background technique [0002] The accumulation of livestock and poultry manure organic fertilizers has been using the traditional method. In the process of processing livestock and poultry manure, there are still shortcomings such as dirty, smelly, large consumption, and inconvenient transportation, which largely restricts the production of livestock and poultry manure organic fertilizers. use. In the past ten years, it has been an effective way to process livestock and poultry manure to produce commercial organic fertilizers in a factory manner. The promotion and application of commercial organic fertilizers can not only solve the problem of livestock and poultry manure pollution, but also effectively reduce the amount of chemical fertilizers used and improve the soil quality of cultivated land, which is of great significance t...
