Problems solved by technology

As a result of this decline, the application of chemical fertilizers must gradually increase each year to maintain high yields
This has led to increased costs and hastened the overall decline of the soil. In recent years, most of the organic fertilizer production in some places has been designed to deal with urban waste.
The organic fertilizer produced by this method contains a lot of garbage, especially some indigestible chemicals, which seriously damages the ecosystem of the farmland, which is not good for the soil and the growth of crops. In Asia, the traditional method of composting is to use straw , fallen leaves, vegetable leaves, sawdust and manure are piled up and placed for a certain period of time to ferment them into fertilizers suitable for application in farmland
This compost is very good for the humus in the fields, but in order to produce this compost, the materials have to be piled up for a long time, and the materials have to be stirred constantly, and even then, the materials cannot all be fermented evenly , but part of it is fully fermented and the other part is not fully fermented, and a large amount of harmful gas will be produced during the composting fermentation process, causing pollution to the environment
At the same time, after the fertilizer produced by composting is fertilized, especially on land with serious nitrogen pollution, its promotion effect on plant growth is low, and it cannot achieve the same effect as chemical fertilizers, and it will also cause further nitrogen pollution to the land.

Embodiment 1

[0042] Take 17-24 parts by mass of livestock and poultry manure, 30-39 parts of straw, 36-43 parts of edible fungus residue, 3-8 parts of potassium humate and 1-3 parts of organic material decomposing agent as materials for fermentation. Slowly dry the edible fungus residue in an oven at 38°C until the water content is ≤27%, then stop drying; the dried edible fungus residue is placed under vacuum conditions, and nitrogen is introduced until the air pressure is 1.4~1.7MPa. Under the conditions, the current is 0.10A, and the current density is 1.8mA / cm 2 , electrostatically treated for 8~10s; air was introduced to normal pressure, and the temperature was raised to 35°C for 17~24h. Organic material decomposing agent Mix the organic material decomposing agent and soil evenly according to the mass ratio of 1:1, adjust the water content to 37-42%, adjust the pH of the system to 7.3-7.8, and place it in a ventilated place at room temperature for 10-25 minutes; put the soil mixture in...

Embodiment 2

[0047] Add measured polyacrylamide into a three-neck flask with stirring, thermometer and vacuum device, stir and heat, vacuum degree 0.098MPa, dehydration at 110°C for 2h, cool down to about 40°C, add toluene diisocyanate, in (80± 2) After heating and reacting at a temperature of ℃ for 2~3h, vacuum degassing and cooling down to room temperature to obtain a coating; take an appropriate amount of organic compound fertilizer, and spray the coating at a spraying speed of 0.4~0.6kg / h through an independent spray system Spray the compound and diethyltoluenediamine components on the surface of the boiling fertilizer particles respectively, so that the two components react on the surface of the fertilizer particles and solidify to form a film; when spraying, the atomization pressure of the nozzle is 0.7~1.2MPa, and the The wind temperature is 20~40℃, and the fertilizer temperature is 30~35℃.

Embodiment 3

[0049] Potassium humate is prepared by the following steps: Dissolve humic acid powder in an appropriate amount of deionized water and heat to 60°C, add 0.1mol / mL sodium hydroxide solution dropwise to pH 9~9.8, according to humic acid Add potassium nitrate and tetrabutyl titanate to the solution at a molar ratio of 1:1.2:0.3, keep a constant temperature of 60°C, and irradiate the reaction system with a UV lamp with a power of 15W as the light source. After reacting for 4 to 5 hours, cool naturally Afterwards, it was aged at room temperature, and after the solvent was evaporated to dryness by a rotary evaporator, the product was dried in an oven at 96° C. and ground to powder.

Abstract

The invention discloses organic compound fertilizer and belongs to the field of fertilizer. The organic compound fertilizer comprises, by mass, 17-24 parts of livestock and poultry feces, 30-39 parts of straw, 36-43 parts of edible fungus residues, 3-8 parts of potassium humate and 1-3 parts of an organic material decomposition agent, the raw materials are subjected to composting fermentation, and a product obtained after composting fermentation is evenly mixed with 0.1-0.7 part of a urease inhibitor and 13.7-18.9 parts of a nitrification inhibitor to form the organic compound fertilizer. Compared with traditional composting, the organic compound fertilizer has the advantages of being shorter in production time, still capable of adapting to application in farmland through fermentation, meanwhile, reducing harmful gas generated by fermentation in the composting process and avoiding pollution to environment in the composting process; meanwhile, planting and producing waste is fully utilized to form a good ecosphere, a good application effect is achieved, and the organic compound fertilizer, like chemical fertilizer, reduces nitrogen pollution of soil when used for solving the problem of nitrogen pollution to the soil.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic compound fertilizer. Background technique [0002] Due to the direct action and obvious effect of chemical fertilizers, the current practice of modern agricultural production around the world still relies heavily on chemical fertilizers. After three to five years of intensive use of chemical substances, the natural fertility of the soil increases with the continuous application of chemical substances every year. Decreased significantly. As a result of this decline, the application of chemical fertilizers must gradually increase each year to maintain high yields. This has led to increased costs and hastened the overall decline of the soil. In recent years, most of the organic fertilizer production in some places has been designed to deal with municipal waste. The organic fertilizer produced by this method contains a lot of garbage, especially some indigestible chemicals, which seriousl...
