Description

Technical Field

[0001] The present invention relates to the technical field of the preparation of light conversion agents, in particular to a method for preparing a light conversion agent for improving plant photosynthesis. Background Art

[0002] Under the background of vigorously developing ecological agriculture and strictly reducing the use of chemical fertilizers and pesticides, new technologies and products are needed to replace traditional chemical input methods in order to achieve the prohibition or reduction of the use of chemical fertilizers and pesticides; the excessive development of chemical agriculture has emerged with the wide application of chemical industrial products (such as chemical fertilizers). The law of nature's development is that "all things grow by the sun". Plants rely on sunlight, air and water to survive in their natural state; the focus of the present invention is to find a breakthrough from the original ecology and respect the biological and biochemical reaction laws of plant growth, especially the photosynthesis law; photosynthesis generally refers to the process by which green plants (including algae) absorb light energy, synthesize energy-containing organic matter from carbon dioxide and water, and release oxygen at the same time; photosynthesis mainly includes two stages: light reaction and dark reaction:

[0003] Light reaction: Driven by light, water molecules are oxidized to release electrons, and the electrons are transferred to NADP + coenzyme through a system similar to the mitochondrial respiratory electron transport chain, reducing it to NADPH; its equation can be expressed as: H 2 O + ADP + P i + NADP + → O 2 + ATP + NADPH + H + ;

[0004] Dark reaction: Using NADPH and ATP generated by the light reaction for carbon assimilation, reducing carbon dioxide to generate sugars; its equation can be expressed as: CO 2 + ATP + NADPH + H + → (CH 2 O) + ADP + P i + NADP + ;

[0005] The above biological and chemical reactions mostly occur in plant chloroplasts, involving the transfer and transformation of electrons and energy, belonging to the category of physical agricultural plant electronics; plants themselves are charged bodies and have electrical conductivity; when plants receive sunlight, a weak current may be generated; the ion exchange phenomenon in photosynthesis also reflects this: in the process of converting light energy into chemical energy, water is decomposed into hydrogen and oxygen, and further generates positively and negatively charged particles, and the exchange movement of ions will form an electric current; as early as in the 1970s, Qian Xuesen proposed that the sixth industrial revolution might be born in China, and its motivation lies in the concern about the photosynthesis efficiency.

[0006] Currently, existing solutions for improving photosynthesis efficiency and electrical cultivation, such as applying fertilizers containing magnesium elements and the biostimulant 5-ALA fertilizer to improve photosynthesis efficiency and electrical cultivation. Among them, the fertilizer containing magnesium elements still implements the solution from providing plant nutrient elements. Increasing magnesium in chlorophyll, which contains magnesium, can increase the chlorophyll content of plants and improve the ability of photosynthesis. The leaf area is limited. Through practice, there is a certain effect, but the role is relatively limited and the improvement amplitude is not large. The biostimulant 5-ALA is a kind of phytochrome, which only increases the light absorption sensitivity of plants. The dosage is very small and it is only used for fine-tuning. For electrical cultivation, the larger research experiment in China is hosted by Professor Liu Binjiang of the Chinese Academy of Agricultural Sciences. An exposed copper wire net was set up 5 meters above the ground and a fast pulse current of 50,000 volts was introduced. 50,000 volts is 200 times the general household voltage. However, the yield of crops treated with electrical cultivation increased by 20-30%, and this figure was obtained under the condition of reducing the use of pesticides by 70-100% and reducing the use of chemical fertilizers by 20%. Its principle is that high-voltage electricity can kill bacteria and viruses in the air and soil, and also affect the surface tension of liquid droplets on the plant surface, accelerating water evaporation. In addition, the electric field can also promote the particle transport in plants (such as bicarbonate and calcium ions), increasing carbon dioxide absorption and photosynthesis. Although it can reduce chemical fertilizers and pesticides and increase production, it is impossible to use it on a large scale. It is impossible to turn vast fields into high-voltage wire nets, and the cost is huge. Electrical cultivation is to change the external spatial environment of plants, making plants and soil in a strong electric and magnetic field. And this invention patent directly changes the charged characteristics of plants themselves, with a built-in electric and magnetic field, and the water-soluble variable resistance changes with the ambient temperature. It does not require large facility investment and is suitable for modern agricultural drone operations.

[0007] It can be seen that the above-mentioned solutions have their own characteristics, but there are also limitations. For example, applying fertilizers containing magnesium elements can only increase the chlorophyll content to a certain extent, and the amplitude of improving photosynthesis efficiency is relatively limited. The dosage of biostimulants is small and they are mostly used as auxiliary regulation means. Although electrical cultivation has shown high yield-increasing potential in local experiments, it is difficult to be popularized on a large scale, and the construction and maintenance costs of its high-voltage wire net are huge. Based on this, the present invention conducts research from the direction of the charged and conductive characteristics of plants during the photosynthesis process, as well as the change laws of plant microcurrent, voltage, and resistance, and explores a new technical route.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for description in the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0029] Figure 1 This is a schematic flow chart of the preparation method of the light conversion agent of the present invention. Specific embodiments

[0030] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0033] As mentioned in the background art, applying fertilizers containing magnesium elements and the photosensitive biostimulant 5-ALA fertilizers to increase photosynthesis efficiency and the electrical cultivation scheme. The fertilizer containing magnesium elements in this scheme still implements the scheme from providing plant nutrient elements. Increasing magnesium in chlorophyll can increase the chlorophyll content of plants and improve the ability of photosynthesis. The area of the leaves is limited. Through practice, it has a certain effect, but the effect is relatively limited and the improvement amplitude is not large; the biostimulant 5-ALA is a kind of phytochrome, which only increases the light absorption sensitivity of plants and is used in very small amounts, only for fine-tuning;

[0034] The larger research experiment on electrical cultivation in China is presided over by Professor Liu Binjiang of the Chinese Academy of Agricultural Sciences. Vegetables are planted on the ground and a bare copper wire mesh is erected 5 meters above it, and a fast pulse current of 50,000 volts is introduced; 50,000 volts is 200 times the general household voltage; although the yield of the crops treated with electrical cultivation has increased by 20-30%, and this figure is obtained under the condition of reducing the use of pesticides by 70-100% and reducing the use of chemical fertilizers by 20%. Its principle is that high-voltage electricity can kill bacteria and viruses in the air and soil, and also affect the surface tension of the liquid droplets on the plant surface, accelerating water evaporation. In addition, the electric field can also promote the particle transportation in the plant (such as bicarbonate and calcium ions), increasing carbon dioxide absorption and photosynthesis; although it reduces chemical fertilizers and pesticides and can increase production, it is impossible to use it on a large scale. It is impossible to turn the vast fields into high-voltage wire meshes, and the cost is huge. Electrical cultivation is to change the external space environment of plants, allowing plants and soil to grow in a strong electric and magnetic field.

[0035] The present invention directly changes the electric characteristics of the plant itself, and the micro-electric field and micro-magnetic field it carries, and the water-soluble variable resistor of the product changes with the ambient temperature; it does not require large facility investment and is suitable for modern agricultural drone operations, and can also be used manually with a small sprayer. The method is simple and practical; it is not picky about regional scenes, and can be used in both facility agriculture and field agriculture; it can be widely used regardless of plant species, from grass to trees; it taps the potential of the plant itself to improve quality and increase yield from sunlight;

[0036] In agricultural production, the main method to promote the improvement of food production level is to increase the fertilizer needed for plant growth, that is, to spread a large amount of chemical fertilizers in the soil. However, the long-term and large-scale use of chemical fertilizers can easily cause the degree of soil compaction to continue to increase, resulting in a continuous decline in the quality of grain, fruit and vegetables, and shallow water resources being polluted by chemical fertilizers. Studies in recent years have shown that the amount of chemical fertilizers input has increased by 1 times, but the organic matter content in the land has become less and less, food production has begun to decline, and the ecological environment has been damaged. For more than a century, biologists have been continuously studying the transfer of rhizobia from leguminous plants to other plants in order to increase grain production, reduce the use of chemical fertilizers, reduce environmental pollution, and develop ecological agriculture. But so far, a better product or method has not been found.

[0037] The present invention provides a method for preparing a photoconverter for enhancing the electrical characteristics of plants and improving plant photosynthesis. The product prepared by the preparation method of the present invention has an effect on the photosynthesis of all plants containing chlorophyll, thereby increasing the yield by about 20% to 50%, and increasing the yield of root crops by about 50% to 80%. It also has obvious resistance and defense functions against low temperature cold currents, rainy and low light, drought and heat waves, etc. Specifically:

[0038] The light conversion agent preparation technology provided by the present invention comprises the following raw materials: 20 to 85 parts of light conversion conductive solution, 0.1 to 0.8 parts of amino acids, 5 to 20 parts of nucleic acid protein, 0.0001 to 0.002 parts of vitamin E, and 0.2 to 4.8 parts of enzymatic trace elements;

[0039] The raw materials are mixed and uniformly dissolved according to weight to obtain a mixed solution, electrolysis is performed in the mixed solution for 0.2 to 5 hours, and then the mixed electrolyzed solution is magnetized and fixed for 0.5 to 6 hours to obtain the product of the present invention;

[0040] The basic principle of the product prepared by the preparation method of the present invention to promote plant growth is:

[0041] It increases the electric current in the plant body, reduces the resistance, develops the conducting tissue, and transports a large amount of organic and inorganic nutrients. It increases the bioelectric current of the plant, accelerates the speed of plant cell division, increases the self-pressure difference of the plant itself, forces the plant root system to enter a strong respiration state, and produces a large amount of hydroxide anion compounds around the plant, so that the plant body from leaves to roots fully absorbs the nutrients needed for growth. The root microorganisms of the plant are abnormally active, and a hotbed of nitrogen-fixing bacteria is established under the induction. It stores the nitrogen inhaled by the plant in the roots and converts it into nitrogen for the plant to absorb; it can realize the direct supply of nitrogen in the air to the plant for absorption;

[0042] The product prepared by the preparation method of the present invention directly changes the charging characteristics of the plant itself and has its own micro-electric field and micro-magnetic field. The water-soluble variable resistance of the product changes with the ambient temperature. It does not require large facility investment and is suitable for modern agricultural drone operations, and can also be used manually with a small sprayer. The method is simple and practical; it is not picky about regional scenes and can be used in both facility agriculture and field agriculture; it can be widely used regardless of plant species, from grass to trees; it taps the plant's own potential to improve quality and increase production from sunlight; it does not increase production and quality through fertilizers and pesticides.

[0043] In the present invention, the photoconductive solution refers to a water-soluble mixed solution prepared from minerals or nanomaterials having light conversion and conductive properties; its main source is screened and purified mineral powder (which may include metal oxides, semiconductor materials, etc.), which is first subjected to nano-processing to obtain the corresponding particle size distribution, and then subjected to a liquefaction process (with auxiliary agents or emulsifiers) to make it uniformly and stably dispersed in the aqueous phase, thereby forming a solution with both light conversion capabilities and conductive properties in a certain band, and its ratio and preparation process can be adjusted accordingly as needed.
