Description

Electromagnetic fertilizer with micro-magnetic field activation function and preparation method thereof

Technical Field

The application relates to the technical field of fertilizers, in particular to an electromagnetic fertilizer with a micro-magnetic field activation function and a preparation method thereof.

Background

The fertilizer is an agricultural product which can provide one or more nutrient elements necessary for the growth of crops to improve the soil property and the soil fertility, and is one of the material bases of agricultural production.

The existing fertilizer mainly comprises organic fertilizer and inorganic fertilizer. The inorganic fertilizer has fast fertilizer effect and simple components, so that the content of single nutrient is relatively high. However, the inorganic fertilizer does not contain organic matters, and is not beneficial to improving the soil fertility after long-term use; in addition, the inorganic fertilizer has single component and incomplete nutrition, and needs to be matched with a plurality of chemical fertilizers or organic fertilizers. Different from inorganic fertilizers, the organic fertilizer contains a large amount of nutrient components required by plant growth, and has relatively long-lasting nutrient supply to plants; it contains vitamins, black humic acid, yellow humic acid, brown humic acid, low molecular organic acid, butyric acid, etc. which affect the nutrition function of plants, and also has physiological activity and stimulation function, and can enhance the respiration function of plants, promote the growth of plant root systems and improve the soil environment. Therefore, compared with inorganic fertilizers, the organic fertilizer is more widely applied.

However, although the organic fertilizer itself contains many kinds of nutrient components, the absorption of the nutrient components such as nitrogen, phosphorus, potassium by plants is still generally low due to the influence of factors such as air temperature, humidity, air flow and the like of the environment. Therefore, it is a problem to be solved by those skilled in the art how to improve the absorption of plants to the nutrient components such as nitrogen, phosphorus, potassium and the like in the organic fertilizer to promote the growth and development of plants.

Disclosure of Invention

In order to improve the absorption of plants to the nutrient components such as nitrogen, phosphorus, potassium and the like in the organic fertilizer and promote the growth and development of the plants, the application provides an electromagnetic fertilizer with a micro-magnetic field activation function and a preparation method thereof.

In a first aspect, the application provides an electromagnetic fertilizer with a micro-magnetic field activation function, which adopts the following technical scheme: an electromagnetic fertilizer with a micro-magnetic field activation function is prepared from the following components in parts by weight: 10-30 parts of amino acid powder, 10-30 parts of humic acid powder, 10-30 parts of polyglutamic acid powder, 500 parts of molasses liquid, 45-60 parts of vermiculite extracting solution, 400 parts of medical stone extracting solution, 0.1-0.3 part of magnetite powder, 10-20 parts of chitin powder, 80-100 parts of rock phosphate powder, 150 parts of potassium feldspar powder and 750 parts of animal organic fertilizer.

By adopting the technical scheme, the amino acid powder and the humic acid powder can provide various nutrients such as vitamins, amino acids, humic acid and the like required by the growth and development of plants. The polyglutamic acid powder can protect the root and hair while providing nutrients, is an optimal conveying platform for closely contacting nutrients and moisture in soil with the root and hair, and can effectively improve the dissolution, storage, conveying and absorption of the fertilizer. The molasses liquid is prepared by taking molasses as a main raw material, adding fermentation strains into a culture medium consisting of nutrient elements such as molasses, nitrogen, phosphorus, calcium, sodium, trace elements, vitamins and the like, and carrying out closed fermentation under the aseptic condition; it contains vitamins, minerals, mycoprotein, nucleic acid, surfactant, somatomedin, etc.; and the fertilizer has strong chelating capacity on divalent cations and can play a role in fixing other nutrient elements in the fertilizer. The chitin powder provides calcium ions for plants on one hand, and unsaturated cationic groups in the molecular structure of the chitin powder can be partially combined with anionic groups in polyglutamic acid powder on the other hand, so that the chitin powder has the effect of stabilizing nutritional ingredients; and the combined polymer can still play the role of polyglutamic acid powder, so that the absorption of plants to the nutrient components of the fertilizer is ensured. The phosphorus ore powder, the potassium feldspar powder and the animal organic fertilizer mainly provide nutrient components such as phosphorus, potassium, nitrogen and the like for plants. The molasses liquid contains various strains, so that the animal organic fertilizer in the fertilizer can be deeply fermented after the fertilizer is applied, and the fertilizer efficiency is improved.

The influence of environmental factors such as air temperature, humidity, air flow and the like on the growth and development of plants mainly changes the transportation state of plants for absorbing nutrients and assimilates by influencing the strength or direction of electromagnetic field. Magnetic magnetite powder is added into the fertilizer to simulate and form a micro magnetic field, so that the regulation and control of nutrient absorption of plants are realized; the vermiculite extracting solution with cation exchange property and adsorptivity and the medical stone extracting solution with certain biological activity are matched, so that the plant can be activated and stimulated in an environment with certain electromagnetic field intensity, the plant respiration is promoted, and the absorption of various ion nutrients by the plant is promoted.

Preferably, the animal organic fertilizer comprises 400 portions of sheep manure organic fertilizer and 150 portions of chicken manure organic fertilizer.

By adopting the technical scheme, more organic matters and nutrient components such as phosphorus, potassium, nitrogen and the like are provided for plants.

Preferably, the composition also comprises the following components in parts by weight: 20-40 parts of bentonite and 35-60 parts of precipitated white carbon black.

The precipitated white carbon black has large internal and external specific surface area and strong physical adsorption performance, and can be used as a carrier to adsorb nutrients in a fertilizer and play roles in fixing nitrogen, potassium and organic matters. The precipitated silica has a median diameter of about 25 μm, coarse particles and a wide distribution range, which is caused by SiO₂Multiple agglomeration of particles. By matching bentonite and precipitated white carbon black, on one hand, agglomeration of the precipitated white carbon black can be properly weakened, and uniform dispersion of the precipitated white carbon black in a fertilizer matrix is facilitated; on the other hand, three adsorption functions of bentonite can be matched with physical adsorption of precipitated white carbon black, for example, nutrients which cannot be subjected to ion exchange adsorption and chemical adsorption can be immobilized through physical adsorption, and the nitrogen fixation, potassium fixation and organic matter fixation capabilities of the fertilizer are improved.

Preferably, the bentonite is sodium bentonite.

the test method comprises the following steps: adopting a large-area test, dividing into 30 groups, namely 1-30 areas, wherein each area is 1 mu, fertilizing in 2018 in 4 months and 28 days, and sowing in 6 months and 10 days; each seedling zone is 4722, 4701, 4700, 4746, 4751, 4730, 4720, 4730, 4726, 4717, 4721, 4720, 4715, 4722, 4732, 4730, 4722, 4728, 4720, 4718, 4719, 4718, 4721, 4718, and 4721; in examples 1 to 20 and comparative examples 1 to 9, the soil in areas 1 to 29 are fertilized respectively in a fertilizing amount of 40 kg/mu and a urea dressing amount of 30 kg/mu; control group corresponds to zone 30; harvesting at 8 days in 10 months in the same year, selecting 3 representative sampling points in each block, taking 30 samples from each sampling point for measuring yield, and taking the average value of 30 samples from each data.

From the results in table 4, it can be seen that after the electromagnetic fertilizer of the present application is applied to corn crops, the ear length, ear thickness and ear number are reduced compared with the control group, but the thousand grain weight is greatly improved, and the yield per mu can be increased by 42.27kg at most. From the results of comparative examples 1 and 2, it is clear that the absence of both chitin powder and polyglutamic acid powder affects the thousand grain weight and the yield per mu is greatly reduced. From the results of comparative example 3, it is known that the non-fermentation of molasses has an adverse effect on the fertilizer efficiency of the fertilizer, probably because the species and the amount of living bacteria in the non-fermented molasses are small, and the synergistic effect on the release of nutrient components such as animal organic fertilizer in the fertilizer is small. The results of the comparative example 4, the comparative example 5 and the comparative example 6 show that the medical stone extracting solution, the vermiculite extracting solution and the magnetite powder have great influence on the exertion of the fertilizer efficiency and the influence effect of the magnetite powder is great; the magnetite powder can generate a micro magnetic field, so that the earth magnetic field can be simulated, and the absorption and transportation of the crops to the nutrient components such as nitrogen, potassium, phosphorus, organic matters and the like can be regulated and controlled, so that the growth and development of the crops are promoted. From the results of comparative example 7, it is understood that if the particle diameters of the chitin powder, the phosphate rock powder, and the potassium feldspar powder are small, the specific gravity of the fertilizer as a whole is relatively decreased, and after application, the fertilizer may be partially agglomerated or stacked in the soil, which is disadvantageous to uniform distribution of the fertilizer in the soil, and the fertilizer efficiency may be relatively decreased.

The results of examples 6-9 are detailed in Table 5 below.

Example 9	16.4	4.7	653.2	340.5	948.24

From the results of examples 6 to 9 in table 5, it can be seen that the amount of the other components in the electromagnetic fertilizer of the present application except for the vermiculite extracting solution, the medical stone extracting solution and the magnetite powder also has an influence on the fertilizer efficiency, and the fertilizer efficiency is better by adopting the mixture ratio of example 7 and example 8.

The results of examples 10-15 are detailed in Table 6 below.

As can be seen from the results of examples 10 to 15 in Table 6, after the precipitated silica and the bentonite are added to the electromagnetic fertilizer, the fertilizer efficiency is greatly improved, and after the electromagnetic fertilizer is used for corn crops, the yield of the corn crops can be increased by at least 43.19 kg/mu, and the highest yield can be increased by 44.59 kg/mu. As can be seen from examples 10 to 12, in the present application, if the precipitated silica and bentonite are mixed with other components at one time, or the mixture A is prepared by stirring at a low speed, or the mixture A is added at one time, the fertilizer effect is adversely affected. From the results of examples 13 to 15, it is understood that the precipitated silica can exert a positive effect on the fertilizer efficiency of the fertilizer by mixing the precipitated silica with bentonite at an ultra high speed. The results of comparative examples 8-9 show that bentonite and precipitated silica in the application have a mutual coordination effect, and if any one of the bentonite and the precipitated silica is removed, the fertilizer efficiency of the electromagnetic fertilizer is reduced.

The results of examples 16-20 are detailed in Table 7 below.
