Detailed Description

The embodiments of the present invention will be described below with reference to specific examples.

A carbon-based full-nutrient liquid water-soluble fertilizer for fertigation comprises 25% of water-soluble biomass, 3% of nitrogen element, 15% of phosphorus pentoxide, 0.05% of potassium oxide and trace elements in mass ratio in the carbon-based full-nutrient liquid water-soluble fertilizer, wherein the trace elements comprise iron, manganese, copper, zinc and boron.

A preparation method of a carbon-based full-nutrient liquid water-soluble fertilizer comprises the following steps:

s001, crushing the organic material, wherein the diameter of the crushed organic material is less than 2 cm;

step S002, putting the crushed organic materials into a reaction kettle, adding potassium hydroxide for alkaline hydrolysis, and adjusting the pH of the mixed solution after alkaline hydrolysis to 6.5-7.5 to obtain alkaline hydrolysis solution;

step S003, adding alpha amylase, cellulase and papain into the alkaline hydrolysis solution for enzymolysis to obtain an enzymolysis solution;

step S004, adding the enzymolysis liquid into bacillus amyloliquefaciens and bacillus subtilis for bacterial hydrolysis, and adjusting the pH of the mixed liquid after bacterial hydrolysis to 6.5-7.5 to obtain the enzymolysis liquid;

step S005, adding ammonium polyphosphate, urea phosphate, potassium pyrophosphate, sugar alcohol chelated calcium, magnesium nitrate hexahydrate, chelated mixed trace elements, compound sodium nitrophenolate, potassium indolebutyrate and nano organic selenium into the bacteria hydrolysis solution for compounding, adding a stabilizer, filtering residues, and retaining clear liquid;

and step S006, carrying out centrifugal filtration on the clear liquid to obtain the carbon-based full-nutrient liquid water-soluble fertilizer.

In a preferred embodiment, the organic material can be herb residue, straw, dry branches and fallen leaves, greening pruning branches, livestock and poultry manure and the like. After a series of alkaline hydrolysis, enzymolysis and bacterial hydrolysis, the long carbon chain of the biomass is broken into a short carbon chain which is easily absorbed and decomposed by plants and microorganisms to form an organic carbon base; then the organic carbon base and the nutrient elements needed by the growth of the plants are proportioned to form the carbon base full nutrient liquid water-soluble fertilizer. In the alkaline hydrolysis process, a potassium hydroxide solution is used, wherein a potassium element can be used as a potassium fertilizer, so that sodium ion salt damage caused by using sodium hydroxide is avoided.

The speed of the organic matter enzymolysis is greater than the speed of the bacterial decomposition, so that the production efficiency is improved, and the bacterial decomposition time can be reduced.

Further, step S002 is specifically to crush the organic material, put the crushed organic material into an alkaline hydrolysis reaction kettle, seal the alkaline hydrolysis reaction kettle, and inject a 48% potassium hydroxide solution into the alkaline hydrolysis reaction kettle, wherein the mass ratio of the organic material to the potassium hydroxide solution is 1: repeatedly stirring organic materials in an alkaline hydrolysis reaction kettle, supplementing sterilized air every 6 hours, controlling the temperature in the alkaline hydrolysis reaction kettle to be 80-85 ℃, controlling the alkaline hydrolysis time to be 48-60 hours until more than 85% of the organic materials in the alkaline hydrolysis reaction kettle are subjected to alkaline hydrolysis, changing the color of liquid in the alkaline hydrolysis reaction kettle into dark brown, injecting phosphoric acid into the alkaline hydrolysis reaction kettle after the alkaline hydrolysis is finished to perform acid-base neutralization, repeatedly stirring, adjusting the pH value of a mixed solution to be 6.5-7.5 by using phosphoric acid or a potassium hydroxide solution, and cooling the mixed solution to normal temperature to obtain an alkaline hydrolysis solution.

The alkaline hydrolysis can break the long carbon chains of lignin and cellulose in the organic material into short carbon chains which are easily absorbed by plants. The used neutralized phosphoric acid can be taken as a phosphate fertilizer to be absorbed by plants.

Further, step S003 specifically is to pump the alkaline hydrolysis solution into a sealed enzymolysis reaction kettle, add alpha amylase, cellulase and papain into the enzymolysis reaction kettle, repeatedly stir in the enzymolysis reaction kettle, control the enzymolysis temperature within the range of 29-31 ℃, the enzymolysis duration is more than 24 hours, until the solid residue rate of the mixed solution is less than 5%, the mixed solution becomes odorless brown liquid, in this process, open the exhaust valve of the enzymolysis reaction kettle every 6 hours, discharge the waste gas into the alkaline hydrolysis reaction kettle, after the exhaust is finished, supplement the air after the sterilization treatment into the enzymolysis reaction kettle, and obtain the enzymatic hydrolysis solution after cooling to normal temperature.

Further, the total mass of the added alpha amylase, the cellulase and the papain accounts for 1-2% of the total mass of the alkaline hydrolysis solution, and the mass ratio of the added alpha amylase, the cellulase and the papain is 4:4: 2.

The alpha amylase, the cellulase and the papain can further break carbon-carbon bonds in lignin molecules remaining in the mixed solution into phenoxy residues, so that the re-polymerization of the degraded short-chain organic products is avoided.

The waste gas has higher temperature, does not need air filtration, and can achieve the effect of energy conservation. Meanwhile, the waste gas after reaction contains volatile nitrogen, and the loss of nutrients can be reduced by recycling. And the waste gas utilization can also solve the environmental protection problem caused by the emission.

Further, step S004 is specifically to pump the enzymatic hydrolysate into a bacteria hydrolysis reaction kettle, add bacillus amyloliquefaciens and bacillus subtilis into the bacteria hydrolysis reaction kettle, wherein the number ratio of the bacillus amyloliquefaciens to the bacillus subtilis is 6:4, the bacteria hydrolysis temperature is controlled within the range of 29-31 ℃, the bacteria hydrolysis time is 48-60 hours, until the solid residue rate of the mixed solution is lower than 1%, the mixed solution becomes odorless light brown liquid, in the process, an exhaust valve of the bacteria hydrolysis reaction kettle is opened every 6 hours, exhaust gas is discharged into the alkali hydrolysis reaction kettle, air subjected to sterilization treatment is supplemented into the bacteria hydrolysis reaction kettle after the exhaust is finished, after the bacteria hydrolysis is finished, the pH of the mixed solution is adjusted to 6.5-7.5 by using phosphoric acid or potassium hydroxide solution, and the mixed solution is cooled to normal temperature to obtain the bacteria hydrolysate.

By adding the bacillus amyloliquefaciens and the bacillus subtilis, insoluble or slightly soluble organic matters can be degraded into soluble organic matters with higher solubility as far as possible. Meanwhile, the fertilizer can provide beneficial microbial bacteria for water-soluble fertilizers, and is beneficial to soil activation and plant growth.

Further, step S005 is specifically to sequentially add ammonium polyphosphate, urea phosphate, potassium pyrophosphate, sugar alcohol chelated calcium, magnesium nitrate hexahydrate, chelated mixed trace elements, compound sodium nitrophenolate, potassium indolebutyrate and nano organic selenium into the bacteria hydrolysis reaction kettle for compounding, wherein the compounding temperature is controlled within a range of 44-46 ℃, after the compounding is completed, a stabilizer is added, the residue is filtered, and the clear liquid is retained.

Before compounding, each gram of the bacteria decomposing liquid contains 50 hundred million beneficial bacteria, and after compounding, the bacteria decomposing liquid is influenced by chemical fertilizers and contains 2000 ten thousand beneficial bacteria. However, the remaining beneficial bacteria have a certain tolerance to chemical fertilizers. After application to the soil, the soil after application of the fertilizer is more adaptable than the microorganisms in the soil, and thus has more advantages in competition. Thus, after the water-soluble fertilizer is applied, the number of harmful bacteria in soil is reduced, and the probability of plant infection with bacteria is reduced.

Further, the mass percentages of the added ammonium polyphosphate, urea phosphate, potassium pyrophosphate, sugar alcohol chelated calcium, magnesium nitrate hexahydrate, chelated mixed trace elements, sodium nitrophenolate, potassium indolebutyrate, nano organic selenium and the stabilizer in the bacteria hydrolysate are respectively 7%, 5%, 1%, 0.8%, 0.1%, 0.05% and 0.05%.

Furthermore, the trace elements in the chelated mixed trace elements are iron, manganese, copper, zinc and boron, and the mass ratio of the trace elements in the bacteria decomposing liquid is 0.2%, 0.1%, 0.05%, 0.15% and 0.3%, respectively.

Furthermore, the carbon-based full-nutrient liquid water-soluble fertilizer comprises 25% of organic matters, 3% of nitrogen elements, 2% of phosphorus pentoxide, 15% of potassium oxide and 0.05% of trace elements by mass, wherein the trace elements comprise iron, manganese, copper, zinc and boron.

The following are the implementation effects of the carbon-based total nutrient liquid water-soluble fertilizer of the invention.
