Description

Technical Field

[0001] The invention relates to the technical field of formula fertilizers, and more particularly to a rainwater erosion-resistant fish protein foliar fertilizer and a preparation method and application thereof. Background Art

[0002] Fish protein fertilizer is a natural functional fertilizer that can be used as base fertilizer, topdressing, root irrigation, drip irrigation, flushing, and foliar spray. Its main function is to increase the content of soil organic matter, promote the reproduction of soil microorganisms, activate soil nutrients, improve soil fertilizer and water retention capacity, and increase soil fertility. Fish protein fertilizer can promote the development of the root system, promote plant growth, improve photosynthesis, facilitate flower bud differentiation, early maturity, and improve quality. Spraying fish protein fertilizer on fruit trees will reduce diseases, the leaves will be green and shiny, the number of fallen flowers and fruits will be reduced, the yield will be high, the taste will be good, the color will be bright, the fruit shape will be good, the quality of melons and vegetables will be good, and the color will be bright. It is a pollution-free, environmentally friendly green nutrient fertilizer.

[0003] Fish protein foliar fertilizer is a fertilizer designed to be applied directly to plant leaves. It is rich in nutrients such as amino acids, proteins, trace elements, etc., which can promote plant growth, increase yield and improve quality. It is common for crops to receive foliar fertilizers regularly, such as to promote their growth or correct nutrient deficiencies. Foliar spraying is the spraying of fine water droplets through small nozzles. Usually, fertilizers for foliar spraying are easily soluble in water or have good dispersion to prevent nozzle clogging. In addition, the concentration of foliar fertilizers is determined according to the crop, spraying conditions and fertilizer type.

[0004] However, since rainfall can reduce the efficacy of fish protein foliar fertilizer on target plants and may cause harmful environmental impacts, it is necessary to improve the rain-resistant property of fish protein foliar fertilizer.

[0005] Therefore, how to develop a fish protein foliar fertilizer that resists rain erosion is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0006] In view of this, the object of the present invention is to provide a fish protein foliar fertilizer resistant to rain erosion and a preparation method and application thereof, so as to solve the deficiencies in the prior art.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A rain erosion resistant fish protein foliar fertilizer comprises the following raw materials in parts by weight: 70-320 parts of nutrients and 2.1-9.6 parts of rain erosion resistant agents; wherein the nutrients comprise fish protein, macronutrients, micronutrients and metal chelates; and the rain erosion resistant agent is a sulfonated polymer.

[0009] Furthermore, the above-mentioned macronutrients are at least one of nitrogen, phosphorus, potassium, sulfur, calcium and magnesium; the micronutrients are at least one of iron, boron, copper and zinc; the metal chelate is at least one of EDTA iron and EDTA calcium; and the sulfonated polymer is at least one of sulfopolyester, 5-sodium sulfoisophthalic acid (5-SSIPA) and sulfonated polyaryletherketone.

[0010] It should be noted that sulfur can be selected from sulfur oxides or potassium sulfate. If calcium salt is used, sulfate should not be included in the remaining part, because this will lead to precipitation of calcium sulfate salt. Micronutrients usually exist in the form of salts and are easily soluble in water. Among them, boron can only exist in the form of boric acid. The anti-rainwater scour agent selected by the present invention is water-soluble, can be well dissolved in water, and can be evenly sprayed on the leaves.

[0011] Furthermore, the above-mentioned rainwater erosion-resistant fish protein foliar fertilizer also includes at least one of a plant growth regulator and a bioactive substance.

[0012] Furthermore, the plant growth regulator is brassinolide; the biologically active substance is at least one of seaweed extract, fermented fish protein from marine fish, nucleic acid nutrients, enzymes and production-increasing amines.

[0013] Furthermore, the above-mentioned rainwater erosion-resistant fish protein foliar fertilizer also includes at least one of an emulsifier and a dispersant.

[0014] Furthermore, the emulsifier is at least one of polyoxyethylene, polyvinyl alcohol and benzylphenol polyoxyethylene ether formaldehyde condensate; and the dispersant is at least one of polyvinyl alcohol and polyacrylamide.

[0015] A further beneficial effect of the above is that the emulsifier and dispersant selected in the present invention have film-forming properties on the leaf surface, so as to improve the solubility, adhesion to the leaves, penetration into the leaves and (or) stability of the water phase of the fish protein foliar fertilizer, thereby enabling the anti-rainwater scour agent (sulfonated polymer) to stay on the leaf surface for a longer time.

[0016] A method for preparing a rainwater-resistant fish protein foliar fertilizer comprises the following steps:

[0017] (1) Weighing the raw materials according to the weight proportions of the above-mentioned anti-rainwater erosion fish protein foliar fertilizer;

[0018] (2) Liquid filling is adopted. First, the nutrients are added and stirred thoroughly. Then, the rain-resistant agent is added and stirred thoroughly. Thus, the rain-resistant fish protein foliar fertilizer is obtained.

[0019] The present invention also claims to protect the use of the above-mentioned rain-erosion-resistant fish protein foliar fertilizer or the rain-erosion-resistant fish protein foliar fertilizer prepared by the above-mentioned preparation method in planting crops, trees or flowers.

[0020] Furthermore, the above-mentioned rain-resistant fish protein foliar fertilizer is sprayed on the leaves by drones, manual labor or sprayers; among them, the spraying amount of drones is 1-3L / mu, and the spraying amount of manual labor or sprayers is 6-8L / mu.

[0021] Furthermore, the above-mentioned crops are root crops, cereal crops or oil crops; root crops are potatoes, sweet potatoes, radishes or beets; cereal crops are corn, rice, wheat, barley or rye; oil crops are soybeans, sunflowers, rapeseed or peanuts; trees are stone fruit trees (nectarines, cherries, plums, etc.), apples, pears, grapes or citrus; flowers and plants are roses and other non-gymnosperm ornamental plants.

[0022] It should be noted that the rain-resistant fish protein foliar fertilizer of the present invention can be compounded with bactericides, disinfectants, pesticides, plant growth regulators, biostimulants or other active compounds (such as bactericidal activity, fungicidal activity, herbicidal activity, insecticidal activity, larvicidal activity, nematicidal activity, snail-killing activity, fish-killing activity, rodenticide activity, slime-killing activity, or fertilizer hormones and / or other growth regulators) when used, and will not have a significant impact on these active compounds.

[0023] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The present invention applies the anti-rainwater scouring agent (sulfonated polymer) in the form of spray, which has excellent rainwater scouring resistance and will not fall off from the leaf surface, so that the fish protein foliar fertilizer can be administered all day and the efficacy can be guaranteed.

[0025] The final product of the rainwater erosion resistant fish protein foliar fertilizer of the present invention has a fluid liquid appearance as the foliar fertilizer, and has the liquid stability of ordinary foliar fertilizers, and will not produce precipitation and other unstable stability of the foliar fertilizer when applied in liquid form.

[0051] Comparative Example

[0052] The fish protein foliar fertilizer is different from Example 1 only in that it does not contain an anti-rainwater erosion agent.

[0053] Performance Testing

[0054] In order to make the test data more comparable and to intuitively reflect the application effect of fish protein foliar fertilizer, the relevant test samples were mainly tested on plants (wheat, corn, peanuts, cucumbers and cabbage) or plant branches (trees) in the early and middle growth stages (including branches), and no comparative tests were conducted on plants or plants in the late growth stage.

[0055] Using weather and rainfall as a necessary condition for the test, data was collected 48 hours after raindrops fell on the ground and finally rained and reached the precipitation conditions of light rain, moderate rain and heavy rain for small plants. The test group used the anti-rainwater scouring fish protein foliar fertilizer prepared in Example 1, and applied it 10-30 minutes before rain in light rain weather; the control group applied it at the same time and was divided into two groups of controls. The control group A used the fish protein foliar fertilizer prepared in the comparative example, and applied it 10-30 minutes before rain in light rain weather; the control group B used the anti-rainwater scouring fish protein foliar fertilizer prepared in Example 1, and adopted the physical shielding method. Small plants applied lantern-shaped rainwater to collect rainwater and finally reached the roots of the plants. Large plants used test branches to cover with polyethylene film alone, and applied it 10-30 minutes before rain in light rain weather.

[0056] Image pro-plus was used to compare the chromaticity and brightness data using Fourier transformation, and the growth rate and index were compared using area calculation. The results are shown in Table 1-3.

[0057] Table 1 Statistical results of light rain test data

[0058]

[0059] As shown in Table 1, in the comparison analysis of the mean values ​​of leaf area growth and leaf chromaticity, there are extremely significant differences in leaf chromaticity and leaf area growth between the experimental group and the control group A, but there is no significant difference with the control group B. Therefore, we can determine that applying the anti-rainwater scouring fish protein foliar fertilizer 10-30 minutes before the rain in light rain weather can achieve extremely significant results. Whether comparing from the leaf chromaticity ratio or the leaf area growth index, except for corn, the light rain resistance to rainwater scouring has reached a retention rate of more than 80%, compared with a retention rate of less than 50% without addition.

[0060] Table 2 Statistical results of moderate rain test data

[0061]

[0062] As shown in Table 2, in the comparison analysis of the mean values ​​of leaf area growth and leaf chromaticity, there are extremely significant differences in leaf chromaticity and leaf area growth between the experimental group and the control group A, but there is no significant difference with the control group B. Therefore, we can determine that applying the anti-rainwater erosion fish protein foliar fertilizer 10-30 minutes before the rain in light rain weather can achieve extremely significant results. Whether comparing from the leaf chromaticity ratio or the leaf area growth index, except for corn, the light rain resistance to rainwater erosion has reached a retention rate of more than 78.2%, compared with a retention rate of 18.9% without addition (this part of the fertilizer effect may also come from the addition of lightning nitrogen).

[0063] Table 3 Statistical results of heavy rain test data

[0064]

[0065] As shown in Table 3, due to the climate and plant growth environment, only corn and peanuts were grown for heavy rain crops, but the results were not significantly different. There was no significant difference in the mean analysis. The specific reason may be that heavy rain is often related to lightning activities, which increase the amount of nitrogen synthesis in rainwater, affecting the difference in the fertilizer effect of fish protein, which is mainly amino acid and peptide nitrogen fertilizer.
