Problems solved by technology

However, most of these imported fertilizers have the following problems: one is high cost and high price, which is difficult to be accepted by customers who produce low-priced agricultural products; the other is that the concentration of nutrients is low, relatively speaking, it increases packaging and transportation cost

Embodiment 1

[0031] The manufacture of humic acid multi-nutrient element liquid fertilizer with Huolinhe weathered coal is carried out according to the following procedures;

[0032] (1) Manufacture humic acid serum

[0033] Take Huolinhe weathered coal (humic acid content > 50%), grind the particle size above 60 mesh, weigh 10Kg; KOH 1.2Kg, urea 30Kg, potassium sulfite 0.4Kg, water 100Kg into the stirring tank, the temperature is controlled at 100± 5°C, react for 3 hours. Then through centrifugation or natural precipitation for 20 hours, the supernatant was transferred to the reactor.

[0034] (2) Manufacture of soluble chitin

[0035] Put 1000 grams of chitin white translucent powder into 20Kg of 40wt% NaOH solution, stir and keep warm at 60°C for 24 hours, the solution is slightly yellow, then add 2wt% CH 3 COOH is made into soluble chitin (ie chitin) solution.

[0036] (3) Manufacture humic acid multi-nutrient liquid fertilizer

[0037] According to the following ratio (weight rat...

Embodiment 2

[0047] Implement the present invention as raw material with lignite, and its technology is as follows:

[0048] (1) Manufacture humic acid serum

[0049] The lignite with humic acid content of about 40% is crushed to more than 100 mesh, weighing 15Kg; NaOH (or Na 2 CO 3 ) 1.0Kg, 45Kg of urea, 0.2Kg of sodium sulfite, and 180Kg of water were put into a stirred tank at 80°C, and reacted for 5 hours. After precipitation, centrifuge to remove solid impurities or insoluble matter, and transfer the clear liquid into the reaction kettle.

[0050] (2) Manufacture of soluble chitin

[0051] Put 500 grams of chitin powder into 20Kg of 40wt% NaOH solution, react at a temperature of 140°C for 1 hour to obtain a yellow-brown liquid and then put it into 2wt% CH 3 COOH solution for later use.

[0052] (3) Manufacture humic acid multi-nutrient liquid fertilizer

[0053] Based on the humic acid clear liquid as 100Kg, add the following raw materials:

[0054] Ammonium hydrogen phosphate ...

Embodiment 3

[0062] The peat containing 30wt% humic acid is used as the raw material. Because the peat has many impurities, it must be crushed and removed before it can be used.

[0063] (1) Manufacture humic acid serum

[0064] After removing impurities, the peat containing about 30% humic acid is crushed to 120 mesh, weighing 25Kg; Na 2 CO 3 2Kg, (NH4 ) SO 3 Add 3Kg of urea and 75Kg of urea into 300Kg of water and put them into the stirring tank together, react at a temperature of 90°C for 4 hours, and after 24 hours of precipitation, the part of the clear liquid is drawn out and transferred into the reactor.

[0065] (2) Manufacture of soluble chitin

[0066] Put 500 grams of chitin powder into 8Kg of 40wt% NaOH solution, react at 100°C for 3 hours to obtain light yellow liquid, then add 22Kg of 2wt% acetic acid solution to it for later use.

[0067] (3) Manufacture humic acid multi-nutrient liquid fertilizer

[0068] Based on the humic acid clear liquid as 100Kg, add the follow...

Abstract

A multi-nutrient liquid fertilizer with high and durably fertility is proportionally prepared from ammonium humate, potassium humate, phosphorus humate, N-P-K humate, trace elements, sulfite as activator (or alkali or alkali-metal carbonate) and chitin solution. Its preparing process is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a humic acid multi-nutrient liquid fertilizer and a manufacturing method thereof. Background technique [0002] Chemical fertilizers (chemical fertilizers for short) can be divided into two types: inorganic fertilizers and organic fertilizers in terms of composition; solid fertilizers and liquid fertilizers in terms of form. Fertilizer plays a significant role in increasing crop yield and is an indispensable production factor in modern agriculture. The negative effect of long-term use of inorganic chemical fertilizers is that the soil fertility is seriously reduced, and even the acid-base balance of the soil is destroyed, causing problems such as soil compaction and salinization; and the nitrate content in agricultural products exceeds the standard , the quality deteriorates. In this case, people try to replace inorganic fertilizers with organic fertiliz...
