Problems solved by technology

For a long time, the technical problem that liquid fertilizers have been unable to solve is that the active ingredients of nitrogen, phosphorus, and potassium in organic liquid fertilizers are all lower than 20%, and the inorganic liquid fertilizers containing more than 30% of active ingredients are easy to mix with phosphorus elements due to the addition of trace elements. The reaction produces precipitation, and expensive metal chelating agents need to be added to increase the cost

Embodiment 1

[0029] Take 500Kg of fresh chicken manure, 400Kg of straw powder, 200Kg of pepper seed meal, 1Kg of EM stock solution, add 10Kg of water, mix evenly with a mixer, seal it in a fermenter, and anaerobically ferment at 65-68°C for 7-10 days. When the temperature reaches above 75°C, turn the pile or ventilate and cool down, and the measured pH value reaches below 5 to end the fermentation, and the fermented product is set aside.

[0030] Mix 3Kg each of citric acid, acetic acid and propionic acid with 18Kg ammonium bicarbonate, add 2000Kg water to prepare a 0.6% organic acid ammonium salt aqueous solution for later use.

[0031] Take 800Kg of the above fermented product and put it into a leaching tank, add 2400Kg of an aqueous solution of organic acid ammonium salt, and use a homogeneous pump to circulate and extract for 50-60 minutes at room temperature, and use a filter press to filter out the filtrate. After the pH of the sodium silicate aqueous solution is adjusted to neutral,...

Embodiment 2

[0034] Take 500Kg of fresh chicken manure, 300Kg of straw powder, 300Kg of pepper seed meal, 1Kg of EM stock solution, add 10Kg of water, mix evenly with a mixer, seal it in a cement pool, and anaerobically ferment at 65-68°C for 7-10 days. When the temperature reaches above 75°C, turn over or ventilate to cool down, and the measured pH value reaches below 5 to end the fermentation, and the fermented product is set aside.

[0035] Mix 4Kg each of citric acid, acetic acid and propionic acid with 24Kg ammonium bicarbonate, add 2000Kg water to prepare a 0.8% organic acid ammonium salt aqueous solution for later use.

[0036] Take 800Kg of the above fermented product and put it into the leaching tank, add 1600Kg of an aqueous solution of organic acid ammonium salt, use a homogeneous pump to circulate and extract for 50 to 60 minutes at room temperature, and use a filter press to filter out the filtrate. After the pH of the sodium silicate aqueous solution is adjusted to neutral, a...

Abstract

The invention relates to organic-inorganic liquid composite fertilizer. The invention is characterized in that fresh chicken dropping, stalk powder and prickly ash seed bran are used as raw materials; EM primary liquid is used as preparatory culture; organic fertilizer leaching liquid is leached through water solution of organic acid ammonium salt at normal temperature after anaerobic fermentation; and urea, ammonium nitrate, monopotassium phosphate, lemery, potassium nitrate and fulvic acid are added into for dissolving so as to obtain the product after being emulsified through a quality even pump. The organic-inorganic liquid composite fertilizer provided by the invention is a black brown sauce-flavor oil type product, with total nitrogen, phosphor and kalium nutrition of more than 36 percent, and with a plurality of medium and mini elements and biological inactive ingredients. The invention is suitable to a plurality of fertilization modes such as agricultural leaf spraying drop filling, root filling and water washing.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizers, and in particular relates to an organic-inorganic liquid compound fertilizer and a production method thereof. Background technique [0002] Since ancient times, organic fertilizer has been the basic fertilizer for agricultural and forestry production in my country. However, with the rapid development of the planting industry, inorganic fertilizers have gradually become people's first choice due to their simple and quick application and the ability to rapidly increase production. While the extensive use of chemical fertilizers has brought huge benefits to agriculture, it has also caused a series of negative effects, such as soil compaction and barrenness due to the reduction of soil organic matter, which will lead to excessive consumption of a large amount of non-renewable energy and land decline. etc. In order to cope with this situation, people have to gradually increase the amount ...
