Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a fish peptide organic aqueous solution fertilizer and a preparation method thereof.
Background
In recent years, liquid fertilizers are attracting more attention, and the liquid fertilizers have the characteristics of low production cost, no dust pollution in the production and transportation processes, convenient application, easy absorption by crops, accurate fertilization, water consumption saving, manpower expenditure reduction, material resource consumption reduction and the like.
Among the essential nutrients for plant growth, the basic element carbon firstly accounts for more than 50%, and secondly, the essential elements are mineral nutrients, such as macroelements and medium-trace elements. Carbon is not only a plant nutrient, but also a carbon framework of plant organic tissues is a combination of mineral nutrients. The relationship between the carbon element and the mineral nutrient element is not similar to the barrel and slat relationship between the large, medium and trace elements, but is a yin-yang relationship with the carbon element as the negative surface and the various mineral nutrient elements as the positive surface. Therefore, the balance of yin and yang relationship of plant growth is large balance and main balance, and the balance of mineral nutrient elements is small balance and secondary balance, if the yin and yang relationship of soil fertility is unbalanced, the balance of mineral nutrient elements can lose meaning. That is, only after the carbon element and the mineral nutrient element in the soil reach a relative balance, the mineral nutrient element can be effectively absorbed and utilized by plants, otherwise, more mineral nutrient elements are ineffective.
The carbon contained in the organic matters of the existing liquid fertilizer is not a true carbon element nutrient, and only small-molecule organic carbon which is soluble in water is the carbon element which can be directly absorbed by plant root systems and soil microorganisms. The water-soluble micromolecular organic carbon has active functional groups such as carboxyl, hydroxyl or amino, and the functional groups have good coordination (complexing) function, and can improve the activity of mineral nutrient elements, so that the effectiveness of absorbing the mineral nutrient elements from soil by plants is improved. In the existing liquid fertilizer, on one hand, the content of water-soluble micromolecular organic carbon is limited, the effective utilization of nutrient elements in the fertilizer cannot be ensured, and on the other hand, the problem of precipitation crystallization and layering flatulence are caused by the instability of the liquid fertilizer.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In a first aspect, the embodiment of the invention discloses a fish peptide organic water solution fertilizer, which comprises the following components in percentage by weight:
macroelement raw materials: 10% -15%;
trace element raw materials: 0.8% -1%;
biochemical fulvic acid: 10% -15%;

Further, the growth of crops requires the absorption of various nutrient elements, which are of equal importance and irreplaceable, in the crop body at different levels. The agricultural sciences community classifies three elements nitrogen, phosphorus and potassium with relatively large demand as macroelements, sulfur, magnesium and calcium as intermediate elements and iron, manganese, molybdenum, copper, boron, zinc and the like as microelements.
The fulvic acid extracted from minerals is called as mineral source fulvic acid, and the biochemical fulvic acid is prepared by treating plant raw materials or fermentation waste liquid by a chemical method. The main components of biochemical fulvic acid are polysaccharides, lignin, proteins and nucleic acids. The biochemical fulvic acid has the following characteristics: the biochemical fulvic acid has small molecular weight and strong permeability, and is easy to be absorbed and utilized by crops; the water solubility is good, the hard water resistance is strong, the flocculation and the precipitation are avoided, and the use is convenient; the active group content is high, the physiological activity is high, and the stress resistance of crops can be improved; the complex and chelating ability to metal ion is strong, the saturation solubility is large, and the complex and chelating ability to metal ion is good in compatibility with trace elements.
The water-soluble small molecular organic carbon liquid is a product which uses plant organic matters as raw materials and adopts a biochemical activation mode to extract nitrogen, phosphorus, potassium and certain trace elements which are required by the growth and development of a large amount of small molecular organic carbon and crops. The water-soluble micromolecular organic carbon liquid contains sugar, alcohol, acid and various functional groups. The water-soluble small-molecule organic carbon liquid is added into the fertilizer to have a synergistic effect on the absorption of nitrogen, phosphorus and potassium, wherein the small-molecule organic carbon contains carboxyl, phenolic carboxyl and other functional groups, has stronger ion exchange capacity and adsorption capacity, and can reduce the loss of ammonium nitrogen; the micromolecular organic carbon can inhibit the fixation of soil to water-soluble phosphorus, slow down the conversion of phosphorus element to invalid state, increase the moving distance of phosphorus element in soil and promote the absorption of phosphorus element by crop root system; the functional groups in the micromolecular organic carbon can absorb and store potassium ions, so that the potassium element can be prevented from flowing away with water in sandy soil and leaching soil, the viscous soil can be prevented from fixing the potassium element, and the absorption of the potassium element by crop root systems is improved. The micromolecular organic carbon and the trace elements can be subjected to complexation reaction to generate a trace element complex which has good solubility and is easy to be absorbed by plants, thereby being beneficial to the absorption of trace elements by the roots of crops. The small molecular organic carbon can also improve the soil structure, prevent soil cracking and soil erosion, regulate the pH value of the soil, and improve and optimize the absorption of nutrition and moisture by crops. Application of small molecule organic carbon promotes crop carbon absorption (CO 2 ) And the photosynthesis of crops is improved.
The fish peptide protein liquid is a high-activity organic matter substance extracted from fish flesh by adopting an enzymolysis technology, contains fish protein, amino acid, humic acid, alginic acid, chitin, polypeptide, polysaccharide and the like, can provide comprehensive and balanced nutrition for crops, and can excite and strengthen the immunity of plants and improve stress resistance. In the embodiment, the fish peptide protein liquid is obtained by adding the fish meat emulsion into protease for enzymolysis, centrifuging and ceramic membrane microfiltration; wherein the crude polypeptide protein content of the fish peptide protein liquid is more than 90%.
The fertilizer synergist comprises active substances aiming at increasing nutrient availability, so that the application amount of the fertilizer can be properly reduced, and the utilization rate of the fertilizer can be improved. In addition, the synergist with functional characteristics is added into the liquid fertilizer, so that the physical property of the liquid fertilizer can be improved through suspension action, and the layered crystallization of the liquid fertilizer is prevented.
In the fish peptide organic water solution fertilizer provided by the embodiment, the water-soluble micromolecular organic carbon can be directly absorbed and utilized by plant root systems and soil microorganisms so as to promote the growth of the plant root systems, improve the soil and enhance the photosynthesis of plants, and the utilization rate of nutrient elements in the liquid fertilizer is improved through the synergistic interaction of the water-soluble micromolecular organic carbon and other components. Meanwhile, the product has high stability, and is not easy to generate flatulence delamination and precipitation crystallization.
Optionally, the components of the fish peptide organic water solution fertilizer also comprise water, and the weight percentage of the water is 33% -51%.
Optionally, the macroelement raw material is high-tower granulation cooling liquid, and the concentration of nitrogen, phosphorus and potassium elements in the high-tower granulation cooling liquid is more than or equal to 100g/L.
And further, the high tower granulation is to heat and melt solid urea or ammonium nitrate to form molten liquid, add corresponding phosphate fertilizer, potash fertilizer, filler and additive into the molten liquid to prepare mixed slurry, send the mixed slurry into a high tower granulator for spray granulation, and obtain the granular fertilizer after sieving and surface treatment of the granular material falling into the tower bottom. In the high tower granulation process, a large amount of fertilizer raw material components (mainly nitrogen, phosphorus and potassium) form tail gas, and the tail gas is discharged into the air, so that environmental pollution and material waste can be caused. The granulating high-tower tail gas washing device can reduce environmental pollution and material waste, and the effective components in the tail gas are recovered through procedures such as a dust remover, spraying and the like, so that the high-tower granulating cooling liquid is obtained. The high tower granulation cooling liquid contains a large amount of nitrogen, phosphorus and potassium element compounds (such as nitrate nitrogen, phosphorus pentoxide and potassium oxide), can be recycled and used as a large amount of element raw materials, reduces the production cost and improves the material utilization rate.
Optionally, the concentration of organic matters in the fish peptide organic water solution fertilizer is more than or equal to 200g/L.

When the specific amount of the water-soluble micromolecular organic carbon liquid and the fish peptide protein liquid are used as raw materials, the content of water-soluble organic matters in the fish peptide organic water solution fertilizer product can be increased, and the soil structure is improved and the growth and development of crops are promoted.
Optionally, the trace element raw materials comprise zinc element raw materials, boron element raw materials and manganese element raw materials.
Further, the zinc element raw material is at least one selected from zinc sulfate, zinc nitrate and disodium zinc ethylenediamine tetraacetate (also called EDTA zinc). The zinc element is an important component of enzymes in crops, participates in synthesis of chlorophyll and auxin, has important influence on photosynthesis function of the crops and growth and development of leaves, stems and roots, and can enhance drought resistance of the crops due to sufficient zinc nutrition. The zinc deficiency of crops can cause short plant head, slow growth and short internode, the veins of the leaves can cause light green and yellow white rust spots, and the root system growth can be influenced. The boron element raw material is at least one of boric acid and borax. The boron element is an important component of ribonucleic acid of crops, is closely related to seedling end and root end development of crops, carbohydrate transportation and transformation, synthesis of sugar substances, pollen formation and pollen tube elongation, and can enhance stress resistance of crops due to sufficient boron nutrition. The boron deficiency of crops can cause the problems of restrained or atrophic top growth points, shorter stem nodes, more lateral buds, withered leaves, flower and bud falling and the like. The manganese element raw material is selected from at least one of manganese sulfate, manganese nitrate and disodium manganese ethylenediamine tetraacetate (also called EDTA manganese). Manganese element participates in the oxygen release process in photosynthesis, is also an important component of indoleacetic acid oxidase prosthetic group, and is an activator of various enzymes in crops. The manganese element plays an important role in promoting seed germination, accelerating nitrogen metabolism, regulating oxidation reaction, promoting photosynthesis and protein synthesis, and the like, and the sufficient manganese nutrition can enhance the disease resistance of crops, accelerate plant growth and maturation and promote the absorption of phosphorus and calcium. The manganese deficiency of crops can cause the phenomena of green and yellow leaf pulp, grey white or brown spots, leaf wrinkling, rolling, withering and the like. Zinc element, boron element and manganese element are added into the fish peptide organic water solution fertilizer to promote plant growth and strengthen photosynthesis.

The aqueous organic liquid fertilizer products of the fish peptides of examples 1, 2 and 3 and comparative examples 1, 2 and 3 were allowed to stand in the same environment for 15 days, and the crystallization delamination conditions of the liquid fertilizer products were observed, and the indexes of the crystallization delamination conditions were classified into "no crystallization delamination", "micro crystallization micro delamination" and "crystallization delamination". The liquid fertilizers of the examples and the comparative examples are respectively sprayed on 6 groups of crop cabbages in the test field, the fish peptide organic aqueous liquid fertilizers of the examples 1, 2 and 3 and the fish peptide organic aqueous liquid fertilizers of the comparative examples 1, 2 and 3 are mixed according to the amount of 1 g/plant, the mixture is diluted by 100 times for spraying, a blank group is arranged for spraying equal amount of clear water, and the performance indexes at the time of harvesting are shown in table 1.
Table 1 fertilizer stand results and crop harvest index for examples and comparative examples
As can be seen from table 1, in the aspect of the standing test, the liquid fertilizer of comparative example 1 showed remarkable crystallization and delamination compared with examples 1, 2, and 3, indicating that the suspending agent effectively improved the stability of the liquid fertilizer; whereas comparative examples 2 and 3 also show minor crystallization and delamination, indicating that there is a synergistic effect of the water-soluble small molecule organic carbon liquid and the suspending agent, the small molecule organic carbon can avoid crystallization and delamination by improving the physical properties (e.g., density) of the liquid fertilizer. In crop trials, the examples and comparative examples showed increased yields compared to the blank, with the examples showing a more pronounced yield-increasing effect. The worst yield increase effect of comparative example 1 compared to examples 1, 2, and 3 indicates that the stability of the liquid fertilizer affects the nutrient absorption of crops. The yield increasing effect of comparative examples 2 and 3 is superior to that of comparative example 1, and still not as good as that of examples 1, 2 and 3. The root and leaf weight gains of examples 1, 2 and 3 are more obvious, which shows that the water-soluble micromolecular organic carbon liquid obviously improves the yield of crops by promoting the growth of root systems of the crops and the photosynthesis of the leaves.
