Description

Technical Field

[0001] The invention relates to the technical field of formula fertilizers, and more particularly to an inorganic anti-ultraviolet 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] In photosynthesis, plant leaves absorb sunlight, causing water and carbon dioxide to form sugar and oxygen. Oxygen is provided to the outer culture medium, and the formed sugars provide a source of nutrition for the plant, promoting the development and growth of the plant. Although sunlight is indispensable for plants, high temperatures and sunburn can accelerate plant photosynthesis, chlorophyll and protein synthesis, nutrient assimilation, and the transportation of nutrients such as calcium, thereby hindering plant development. In addition, ultraviolet (UV) and infrared (IR) sunlight can have harmful effects on plants, such as deterioration of cell walls and structures, and produce biological and biochemical changes. Therefore, fish protein foliar fertilizers should be used before 10 noon or after 16:00 in the afternoon during intensive agricultural use, otherwise ultraviolet rays will destroy the active ingredients and easily cause phytotoxicity.

[0005] Therefore, how to develop a fish protein foliar fertilizer that enhances resistance to ultraviolet rays is a problem that those skilled in the art are eager to solve. Summary of the invention

[0006] In view of this, the object of the present invention is to provide an inorganic anti-ultraviolet fish protein foliar fertilizer 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] An inorganic anti-ultraviolet fish protein foliar fertilizer comprises the following raw materials in parts by weight: 70-320 parts of nutrients and 7-22.4 parts of inorganic ultraviolet absorbers; wherein the nutrients comprise fish protein, macronutrients and micronutrients; and the inorganic ultraviolet absorbers comprise ultrafine bentonite, calcium powder and mineral humic acid.

[0009] Furthermore, the above-mentioned macronutrient is at least one of nitrogen, phosphorus and potassium; the micronutrient is at least one of iron, manganese, calcium and boron.

[0010] Furthermore, the inorganic anti-ultraviolet fish protein foliar fertilizer also includes at least one of a plant growth regulator and a bioactive substance.

[0011] Furthermore, the plant growth regulator is brassinolide; and the biologically active substance is seaweed extract.

[0012] Furthermore, the inorganic anti-ultraviolet fish protein foliar fertilizer also includes at least one of an emulsifier and a dispersant.

[0013] Furthermore, the emulsifier is at least one of calcium dodecylbenzene sulfonate (pesticide emulsifier No. 500 or emulsifier ABSCA), tristyrylphenol polyoxyethylene ether, alkylphenol formaldehyde resin polyoxyethylene ether (pesticide emulsifier No. 700) and phenylethylphenol formaldehyde resin polyoxyethylene ether (Ningru No. 700); the dispersant is at least one of rosin grafted polymer carboxylate (GY-JZS-B), modified lignin sulfonate dispersant (DC01) and polycarboxylate polymer dispersant (DC04).

[0014] A further beneficial effect of the above is that the emulsifier and dispersant selected in the present invention also 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 inorganic ultraviolet absorber (ultrafine bentonite, calcium powder and mineral humic acid) to stay on the leaf surface for a longer time.

[0015] A method for preparing an inorganic anti-ultraviolet fish protein foliar fertilizer specifically comprises the following steps:

[0016] (1) Weighing each raw material according to the weight proportion of the inorganic anti-ultraviolet fish protein foliar fertilizer;

[0017] (2) Liquid filling is adopted. First, the nutrients are added and stirred thoroughly. Then, the inorganic ultraviolet absorber is added and stirred thoroughly. Thus, the inorganic anti-ultraviolet fish protein foliar fertilizer is obtained.

[0018] The present invention also seeks to protect the use of the inorganic anti-ultraviolet fish protein foliar fertilizer or the inorganic anti-ultraviolet fish protein foliar fertilizer prepared by the preparation method in planting crops.

[0019] Furthermore, the inorganic anti-UV fish protein foliar fertilizer is sprayed on the leaves by drones, manual labor or sprayers; the spraying amount of drones is 1-3L / mu, and the spraying amount of manual labor or sprayers is 6-8L / mu.

[0020] 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 nectarines, cherries, plums, apples, pears, grapes or citrus; flowers and plants are roses and other non-gymnosperm ornamental plants.

[0021] It should be noted that the inorganic anti-ultraviolet 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.

[0022] 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:

[0023] The present invention applies inorganic ultraviolet absorbers (ultrafine bentonite, calcium powder and mineral humic acid) in the form of spray, which can form a barrier film on plant leaves or plant fruits (fruits), prevent sunburn without reducing photosynthesis by absorbing or reflecting ultraviolet radiation, and enable fish protein foliar fertilizer to be administered all day and ensure efficacy.

[0024] The final product of the inorganic anti-ultraviolet fish protein foliar fertilizer of the present invention has a fluid liquid appearance and has the liquid stability of ordinary foliar fertilizers, and does not produce precipitation and other unstable stability of the foliar fertilizer when applied in liquid form.

[0052] Performance Testing

[0053] 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, pears 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.

[0054] The test was conducted on a sunny day in natural weather, and data was collected after the small plants had been sunny for 48 hours. The test group used the inorganic anti-ultraviolet fish protein foliar fertilizer prepared in Example 1, which was applied at noon on a sunny day; the control group applied both, and was divided into two control groups, the control group A used the fish protein foliar fertilizer prepared in the comparative example, which was applied at noon on a sunny day; the control group B used the fish protein foliar fertilizer prepared in the comparative example, which was applied in the morning and evening on a sunny day.

[0055] Image pro-plus including Fourier transform was used to calculate the utilization area and compare the growth rate and index. The results are shown in Table 1.

[0056] Table 1 Statistical results of UV resistance test data

[0057]

[0058] As shown in Table 1, in the comparative analysis of the mean value of leaf area growth, 48 hours after application, there was a very significant difference in the leaf area growth index between the experimental group and the control group A. Therefore, we can determine that compared with the control group A, the application of inorganic anti-ultraviolet fish protein foliar fertilizer at noon on a sunny day can achieve significant results.

[0059] Comparing the leaf area growth index, there is no statistically significant difference in the efficacy between the experimental group and the control group B (mainly there is no significant difference in fertilizer efficiency), but there is a very significant difference in the leaf area growth index between the control group A and the control group B, so applying foliar fertilizer in the morning and evening on sunny days has important production significance.

[0060] At the same time, the inorganic ultraviolet absorber added by the present invention is of great significance to the ultraviolet stability of foliar fertilizers, and has important significance and practical functions in the use of pesticides throughout the day in intensive agriculture.

[0061] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
