Abstract
The application relates to a water-soluble fertilizer and a preparation method thereof, wherein the water-soluble fertilizer comprises one or more of major elements, medium elements and trace elements, and further comprises saccharifying enzyme and cellulase, and is characterized by further comprising bovine serum albumin, the water-soluble fertilizer water-insoluble matters are not more than 0.5%, and G4 crucible filtration is adopted for detecting the water-insoluble matters. The application can effectively solve the problem of pipeline blockage caused by using water-soluble fertilizer.
Description
Technical Field
The application relates to a water-soluble fertilizer and a preparation method thereof.
Background
Drip irrigation has the advantages of saving water, fertilizer and labor, so that the drip irrigation is widely applied, however, new problems are caused when the drip irrigation is adopted, and although the water-soluble fertilizer has related standards, the water-soluble fertilizer produced according to the standards cannot completely solve the problem of pipeline blockage after a period of use, and the service life of the pipeline is directly influenced.
Another reason for the blockage of the drip irrigation pipeline is that the fertilizer pool contains nutrients, so that green algae are easy to generate when sunlight is sufficient in summer, and green algae are generated in the pipeline under the irradiation of sunlight due to uncleanness, so that the pipeline can be blocked when the drip irrigation pipeline is applied to drip irrigation, and the service life of the pipeline is influenced.
The method for killing the green algae is generally to kill the green algae by adopting quicklime and an oxidant, however, calcium hydroxide finally produced by the quicklime is a slightly soluble substance, so that the pipe can be blocked by the calcium hydroxide in the pipe, and alkali has a corrosion effect on the pipe, so that the service life of the pipe is influenced; when the oxidizing agent is used for killing green algae, the oxidizing property of the oxidizing agent has a corrosion effect on the pipeline, and the service life of the pipeline is also influenced.
The prior art CN108546197A biofertilizer and the preparation method thereof, although 0.1-0.5% of enzyme is added, and the enzyme is cellulase or/and saccharifying enzyme, specifically, corn straw is firstly cut into segments, then is mixed with rice husk and saw dust, crushed, is placed under the conditions of 130-150 ℃ and 130-150kPa for sterilization for 2-5 minutes, the mixture is obtained after the enzyme is added, water with the mass of 0.5-1.5 times of that of the mixture is added, and the mixture is subjected to enzymatic hydrolysis for 1-5 days at 38-45 ℃ after uniform mixing, so that the enzymatic effect of the enzymatic mixture is enzymatic, and the technical teaching that the combination of the cellulase and saccharifying enzyme can solve the problem of pipeline blockage caused by drip irrigation of water-soluble fertilizer is not provided.
The improved formulation of the prior art CN 1163442C fertilizer additive concentrate gives a technical suggestion for the addition of nonionic surfactants, but it gives a final finding that the addition of specific nonionic surfactants selected from alkylaryl polyether alcohols to the formulation can give the formulation the desired properties such as increased stability. These solutions can be stored for extended periods of time and conveniently used as carriers for impregnating N-alkyl thiophosphoric triamides on ureido solids using a wide variety of conventionally available fertilizer mixers for fertilizer processors and dispensers. Any suitable or conventional apparatus may be used to apply the formulation to the solid fertiliser. Preferably, the formulation is fully saturated with solid fertilizer. The fact that the above formulations are generally miscible with typical urea-containing liquid fertilisers also makes these formulations extremely useful in use. Any suitable or conventional equipment may be used to incorporate the formulation into the liquid fertilizer. The nonionic surfactant is seen to increase stability, solve the problem of long-term storage of the solution, and to be conveniently used as a carrier for impregnating N-alkyl thiophosphoric triamide on ureido solids using a wide variety of conventionally available fertilizer mixers and dispersers for fertilizer processors and dispersers. It can be seen that the problem that the drip irrigation pipeline service life is influenced by the pipeline blockage caused by drip irrigation with the water-soluble fertilizer is not solved.
The patent number CN 108249991A is a preparation method of water-soluble fertilizer, and provides technical teaching for adding nonionic surfactant, but the surfactant is nonionic surfactant. Fatty acid as the main constituent of the stratum corneum of the leaf surface
Polymeric compounds such as compounds and pectins can generate a certain amount of negative charges, so that a low-to-high charge gradient is formed from the outer surface to the cell wall, and ionic surfactants can cause damage to the leaves. It can be seen that the problem that the drip irrigation pipeline service life is influenced by the pipeline blockage caused by drip irrigation with the water-soluble fertilizer is not solved.
CN 107721654A discloses a biological humic acid-containing water-soluble fertilizer and a preparation method thereof, which discloses a technical suggestion of adding a separation sub-surfactant, the hexadecyl polyglucoside and chitosan quaternary ammonium salt are compounded to achieve a good antibacterial effect, and can form a stable macromolecular physical combination structure with a stabilizer and an organosilicon emulsion, the stabilizer adopts a laurinol polyoxyethylene ether type gemini surfactant, has stronger stability and the capability of forming a macromolecular coating structure, forms a stable oil-in-water structure, prevents precipitation of substances, and the stable macromolecular physical combination structure formed after the compounding effectively reduces the surface tension of the product, so that the fertilizer can be fully spread to play a role, and therefore, the utilization rate of the water-soluble fertilizer is improved.

As can be seen from the data in Table 1, CK was filtered using a G1 crucible, and although the content of water insoluble matter was measured as in the case of the G4 crucible, it had a problem of clogging the pipe, which affected the service life of the pipe.
As can be seen from the comparison of the data of the comparative examples 1, 2 and 1 and the data of the comparative examples 5, 6 and 3, the combination of the saccharifying enzyme, the cellulase and the bovine serum albumin in the embodiment 1 can better solve the problem of blocking the drip irrigation pipeline, and any condition of any change of the saccharifying enzyme, the cellulase and the bovine serum albumin can influence the use effect of the water-soluble fertilizer.
As can be seen from the data of examples 1, 3, 4 and 2 and the comparison of examples 7, 8, 3 and 4, the combination of saccharifying enzyme, cellulase, bovine serum albumin and nonionic surfactant can better solve the problem of drip irrigation pipeline blockage, and any condition of any change of saccharifying enzyme, cellulase combination, bovine serum albumin and nonionic surfactant can influence the use effect of the water-soluble fertilizer.
From comparison of the data of comparative examples 9, 10, 11 and 4, it can be seen that the selection of the surfactant (anionic, nonionic and cationic) directly affects the use effect of the water-soluble fertilizer, wherein example 4 using the nonionic surfactant can better solve the problem of pipe blockage.
This may be that the nonionic surfactant is able to promote enzyme activity compared to the anionic surfactant to better address the problem of pipe blockage, or that bovine serum albumin is bound to the anions in the anionic surfactant and the cations in the cationic surfactant; thus, the problems of pipeline blockage can not be well solved by the comparison 9, the comparison 10 and the comparison 11. The mechanism of which needs to be further studied.
