Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of preparation method of tea tree vernalization special fertilizer.
Background technique
In recent decades, China's tea yield and quality increase substantially, and wherein play can not for the update of fertilizer practice
The effect of substitution.Tea tree is perennial crop, machine matter contained in the yield and quality of tealeaves and the soil of plantation tea tree, complete
Nitrogen, available N, P, K etc. are closely related.Organic fertilizer is the full price fertilizer with various nutrient elements, and tea place application of organic fertilizers can
Soil physico-chemical property is improved, balanced soil nutrient improves utilization rate of fertilizer, promotes growth of tea plant, to improve the yield of tealeaves
And quality.In addition to base manure, tea tree generally also needs the first time topdressing before top dressing, especially spring tea exploitation, and tea tree passes through a winter
" rest and reorganization ", in spring in next year, temperature, rainwater condition maturity, bud-leaf falls over each other to sprout, there is an urgent need to nutrition, top dressing have promotes tea
Bud-leaf early hair, the effect that multiple, hair is neat, hair is strong are set, so, also it is called " vernalization fertilizer ".
It was found that the absorbability of tea tree nutrient is 3 times stronger than Wintering Period when spring tea sprouts, to nitrogen utilization efficiency also compared with
It is high.High-quality, high yield tea place picking intensity is big, requires leaf quality high, has the characteristics that early adopt, tender adopt, adopt in batches, tea tree more
Nutrient consumption is also larger, so the effect of vernalization fertilizer is extremely important to the economic benefit in tea place.In the prior art, tea tree is dedicated urges
The ingredient of bud fertilizer is often more complex, such as Chinese patent CN106167439A provides the top dressing liquid of tea picking phase a kind of, should
Fertilizer composition includes 30~40 parts of tea tree fertilizer special for organic, 5~15 parts of vegetables, 5~10 parts of oil meal, 3~7 parts of potassium dihydrogen phosphate, carbon
3~6 parts of sour hydrogen ammonium.Not only ingredient is more complex for the top dressing liquid that the technology provides, and preparation is time-consuming also longer, needs first that tea tree is dedicated
Organic fertilizer, which is put into the water of 3~5 times of weight, to be impregnated 5~10 days, organic fertilizer filtrate is obtained by filtration, then vegetables are broken into vegetable juice,
Mixing is placed on 20~25 DEG C of 4~10h of processing, oil meal, potassium dihydrogen phosphate and ammonium hydrogen carbonate is then sequentially added, then at 20~25
DEG C environment in handle 2~4 days.
So the preparation method for how obtaining a kind of dedicated vernalization fertilizer of the efficient tea tree suitable for production is still this field
Technical staff's yet unresolved issue.
Summary of the invention
It is an object of the invention to solve the dedicated vernalization fertilizer complicated component of tea tree in the prior art, the cumbersome time-consuming of preparation process
Long defect, and then a kind of preparation method of dedicated vernalization fertilizer of the efficient tea tree suitable for production is provided.
Above-mentioned purpose of the invention is achieved through the following technical solutions:
A kind of preparation method of tea tree vernalization special fertilizer, including,
The mixed serum for preparing biomass carbon, ammonium hydroxide and humic acid, is passed through CO2Or contain CO2Gas；
Collect obtained solid and drying.
It further include being passed through the CO2Or contain CO2Gas when the mixed serum is stirred.
It further include often being passed through the CO2Or contain CO20.5~3min of gas after, rotten plant is added into the mixed serum
Acid.
Often it is passed through the CO2Or contain CO20.5~1min of gas after, add humic acid into the mixed serum.
The biomass carbon is that biomass is carbonized to obtain at 450~530 DEG C.
Biomass is carbonized at 450~530 DEG C, obtains pyrolysis gas and biomass carbon；
Pyrolysis gas is burnt, burning gained flue gas is collected；
The biomass carbon is crushed, is made into mixed serum with ammonium hydroxide and humic acid, the flue gas is passed through and is reacted；
Collect obtained solid and drying.
Pyrolysis gas is condensed or sprayed, biogas is obtained, is burnt, burning gained flue gas is collected.
The condensate liquid of the pyrolysis gas or spray liquid are subjected to water-oil separating, gained water phase is sprayed to the biomass carbon
On, the preparation of mixed serum is then carried out again.
Liquid is used as Recycling Mother Solution after the collection solid.
Technical solution of the present invention has the advantages that
1. the preparation method of fertilizer special for tea trees provided by the invention, preparation biomass carbon, ammonium hydroxide and humic acid is mixed first
Slurries are closed, then are passed through CO2Or contain CO2Gas, then separation product obtains tea tree vernalization special fertilizer after dry.By using height
Aromatization, porous solid matter biomass carbon are spent as the nuclei of crystallization/carrier, so that the CO being passed through2It reacts with ammonia water, generates carbon
Sour hydrogen ammonium.Ammonium hydrogen carbonate property is unstable, volatile, plant recovery of nutrient is low be easy to cause waste, and the application is different from biology
Matter charcoal is mixed with the direct of ammonium hydrogen carbonate, be using the biomass carbon of surface acidic functionality rich in as the nuclei of crystallization/carrier,
Biomass carbon based compound fertilizer is prepared with physical and chemical adsorption-chemical reaction method, that is, utilizes NH3+CO2+H2O is in charcoal matrix
Hole surfaces externally and internally is reacted and is obtained, and after the combination with biomass carbon and humic acid, the comprehensive benefit of nitrogen has been effectively ensured
With rate, there is remarkable result on to tea tree spring vernalization；And stability is high, achievees the effect that sustained release, overcomes traditional ammonium bicarbonate
Fertilizer easily decomposes the shortcomings that volatilization, effectively improves the utilization rate of fertilizer.
2. the preparation method of fertilizer special for tea trees provided by the invention, the operation by adding humic acid can obtain effect more
Excellent tea tree vernalization special fertilizer.The present invention is also by using the combustion product gases of pyrolysis gas produced by charing biomass carbon as dedicated
Fertile raw materials for production turn waste into wealth the carbon dioxide sequestration in combustion product gases, reduce greenhouse gas emission；Meanwhile pyrolysis gas fires
Burn the SO in flue gas2、NOxIt can be also converted into ammonium nitrate and ammonium sulfate, be adsorbed on biomass carbon, collaboration improves fertilizer efficiency.
3. the preparation method of fertilizer special for tea trees provided by the invention still further preferably passes through pyrolysis gas condensate liquid or spray
The biomass carbon of the sprinkling of water phase obtained by liquid water-oil separating, so that biomass carbon contains multiple nutritional components.In addition, biomass carbon is also
It is good soil conditioner, nutrient can also be provided while capable of improving soil texture for crop, while it is useless to realize agricultural
The comprehensive utilization of gurry, biomass carbon and fertilizer are complex as soil-fertilizer-environment and propose comprehensive solution.
