Description

Technical Field

[0001] The invention belongs to the technical field of fertilizers, and specifically refers to a preparation method and application of a fertilizer for promoting plant chlorophyll synthesis. Background Art

[0002] In modern agricultural production, improving the yield and quality of crops is a vital goal. Chlorophyll, as a key substance for plant photosynthesis, plays a decisive role in plant growth and development. Adequate chlorophyll content can enhance the photosynthesis efficiency of plants, promote the absorption and conversion of nutrients, and thus improve the yield and quality of crops.

[0003] Chlorophyll is an important substance for plant photosynthesis, and its content directly affects the growth, development and yield of plants. Although there are many types of fertilizers on the market, there are relatively few fertilizers specifically designed to promote plant chlorophyll synthesis. Existing fertilizers are not effective in promoting chlorophyll synthesis and cannot meet the needs of efficient production in modern agriculture.

[0004] Although there are many types of fertilizers on the market, there are relatively few fertilizers specifically designed to promote plant chlorophyll synthesis. Traditional fertilizers tend to focus on providing macronutrients such as nitrogen, phosphorus, and potassium, but not enough attention is paid to trace elements and organic matter. These traditional fertilizers are not effective in promoting chlorophyll synthesis and cannot meet the needs of efficient production in modern agriculture.

[0005] In addition, as people pay more and more attention to environmental protection and sustainable development, higher requirements are placed on the environmental protection and safety of fertilizers. Traditional fertilizers may pollute the soil, water and air during production and use, and may also cause potential harm to human health. Therefore, it is of great practical significance to develop an environmentally friendly, safe and efficient fertilizer that promotes plant chlorophyll synthesis. Summary of the invention

[0006] The purpose of the present invention is to provide a preparation method and application of a fertilizer that promotes plant chlorophyll synthesis. The fertilizer provides the macroelements, trace elements and organic substances required for plant chlorophyll synthesis through a scientific and reasonable formula, providing sufficient energy for plant growth and development; organic substances such as humic acid can increase the organic matter content of the soil, improve the soil aggregate structure, and improve the soil's ability to retain water and fertilizer. This helps to reduce soil erosion, prevent soil and water loss, and create a good soil environment for plant growth; the trace elements in the fertilizer exist in a chelated state, have high stability, are not easily fixed by the soil, can improve the plant's absorption and utilization rate of trace elements, and reduce physiological diseases caused by trace element deficiency; the fertilizer of the present invention is suitable for various crops, flowers, fruit trees and other plants, and has a wide range of applicability.

[0007] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present invention is as follows: a preparation method and application of a fertilizer for promoting plant chlorophyll synthesis, wherein the fertilizer comprises the following components in parts by weight: 60-100 parts of a macroelement compound; 0.1-1 parts of a trace element compound; 5-20 parts of an organic mixture; 1-10 parts of a surfactant; and 2-8 parts of a dispersant.

[0008] Preferably, the fertilizer comprises the following components in parts by mass: 80-90 parts of macroelement compounds; 0.2-0.6 parts of trace element compounds; 7-15 parts of organic mixture; 1-3 parts of surfactant; and 3-5 parts of dispersant.

[0009] Furthermore, the macroelement compound consists of urea, diammonium phosphate and potassium sulfate.

[0010] Furthermore, the trace element compound consists of chelated iron, chelated magnesium and chelated zinc.

[0011] Furthermore, the organic matter mixture consists of one or more of humic acid, amino acids, corn straw, soybean straw and pigeon droppings.

[0012] Furthermore, the surfactant is composed of one or more of sodium dodecylbenzene sulfonate, hexadecyltrimethylammonium bromide and polyoxyethylene sorbitan fatty acid ester.

[0013] Furthermore, the dispersant is composed of one or more of sodium polyacrylate, polycarboxylate and lignin sulfonate.

[0014] The present invention also provides a method for preparing a fertilizer for promoting plant chlorophyll synthesis, the method for preparing the fertilizer comprising the following steps:

[0015] (1) Raw material screening and pretreatment: select urea, diammonium phosphate, potassium sulfate, and chelated iron, chelated magnesium, chelated zinc, and prepare an appropriate amount of organic matter;

[0016] (2) Precise mixing: The above raw materials are mixed in a certain proportion, and the optimal ratio of nitrogen, phosphorus and potassium is determined according to the nutrient requirements of different plants and the fertility of the soil to ensure that the content of various elements meets the requirements for promoting plant chlorophyll synthesis;

[0017] (3) Granule processing: When the mixed raw materials are processed, a combination of multi-stage grinding and stirring is used. The raw material particles are first refined to a certain degree by coarse grinding, and then fine grinding is performed to make the particle size reach 80-120 mesh. At the same time, an appropriate amount of surfactant and dispersant is added during the stirring process to improve the dispersion and uniformity of the raw materials. Finally, the spray granulation method is used to make the fertilizer particles more uniform and round.

[0018] The present invention also provides an application of a fertilizer for promoting plant chlorophyll synthesis. The fertilizer of the present invention is suitable for various crops, flowers, fruit trees and other plants, and can be used as base fertilizer and topdressing. When used, the appropriate amount of fertilizer and time of fertilization are determined according to the needs of different plants and soil conditions. Generally, the fertilizer can be evenly spread on the soil surface, and then plowed to fully mix the fertilizer with the soil.
