Description

Technical Field

[0001] This invention relates to the technical field of an oxygen-producing functional composition having the following characteristics and agricultural methods using the same: during cultivation, the oxygen-producing functional composition provides sufficient oxygen to maximize root strength and growth activity by maximizing root respiration during the respiration of plant roots growing in soil and water, thereby achieving a high-quality and high-quantity oxygen-based crop farming method. Background Technology

[0002] During crop cultivation, root growth is related to air (oxygen) and temperature in the soil, while root respiration, enzyme activity, microbial activity, and the role of root fungi are closely related to air in the soil.

[0003] Trees typically have deep roots and poor air circulation, which prevents them from growing like fine roots on the ground surface. Therefore, it is very important to induce fine roots to grow to the ground surface and even deep underground to ensure the healthy growth of trees.

[0004] In addition, the amount and circulation of air in the soil are very important in order to ensure smooth oxygen supply by expelling carbon monoxide produced by root respiration and the decomposition of organic matter to the ground.

[0005] For plants to grow strong, their roots must be robust. In addition to sufficient nutrients and water, plant roots also need oxygen to grow vigorously.

[0006] What is easily overlooked is that plants need to breathe not only through their leaves but also through their roots, and proper root respiration is essential for healthy growth. When cultivating in soil, a method of mixing coarse-grained white perlite is used to create air holes that allow for good drainage.

[0007] Moreover, in hydroponics where the roots are submerged in water, oxygen deficiency is more likely to occur. Therefore, it is important to pay attention to oxygen supply at all times. In particular, the temperature of the nutrient solution rises in summer, which can reduce the plant's ability to absorb oxygen, making good oxygen supply even more important.

[0008] The minimum oxygen concentration required for crop growth is 5 ppm, and therefore should not be lower than this value. The energy required for plant root growth is obtained through respiration, which is used for growth or physiological functions. Therefore, if the dissolved oxygen near the roots is insufficient, metabolic disorders will occur due to a sharp decrease in respiration, leading to stunted growth. In particular, the higher the temperature, the more vigorous the plant growth, and the more oxygen it needs to absorb nutrients. However, the dissolved oxygen concentration in the water supply drops sharply, becoming a limiting factor for growth.

[0009] At this time, if the dissolved oxygen concentration is not increased and continues for 2-3 hours, the dissolved oxygen will be depleted. If it is below 2 ppm, the crop may die. Conversely, if the dissolved oxygen is supplied sufficiently, the supply of nutrients and water to the crop will become smooth, the crop will grow better, and the quality and yield will increase by more than 20%.

[0010] Therefore, the solution required for oxygen farming is to provide crops with 20 ppm or more of the basic oxygen required for root respiration, thereby maximizing the catabolism / biochemical processes of crop metabolism and thus maximizing the energy efficiency of photosynthesis. This would allow the reproductive energy of underground roots, which is the most important condition for crop vegetative and reproductive growth, to reach more than twice that of existing cultivation methods (13:3:0), thereby maximizing the survival rate of roots in soil and water and ensuring their longest lifespan.

[0011] In soil and hydroponics, when the roots are rich in oxygen in the soil and water, the necessary technical solutions are to optimize root respiration and survival rate, maximize dissimilation, assimilation, and biochemical processes, maximize nutrient or water absorption rates, normalize metabolism, enhance crop resistance, reduce the amount of topdressing and pesticides used, maximize the stability of crop growth status, increase yield and marketability, overcome and eliminate salt accumulation, and overcome and eliminate gas barriers or continuous cropping barriers. These measures can greatly improve the crop growth environment, including the soil and hydroponic growing environment.

[0012] In addition, it should be considered that when the roots lack oxygen, the survival rate of the roots is low, the absorption rate of water and nutrients is reduced, the root metabolism is impaired, assimilation and dissimilation are reduced, biochemical processes are low, nutrients are lost, excessive topdressing is applied, salt accumulation occurs, and resistance to diseases and pests is reduced. As a result, not only can the crop not grow normally, but the production of ethylene also increases, leading to root death.

[0013] Therefore, oxygen farming enhances the fundamental vitality and life force of the roots, leaves, stems, and fruits of soil-grown and hydroponic crops, thereby improving the marketability and yield of crops and making them more resistant to pests and diseases. Thus, it is believed that oxygen in the soil roots is very important for farm-grown crops. However, due to a lack of technical expertise, the technology for supplying oxygen to crop roots for respiration is unsatisfactory or requires a lot of funding, which prevents farmers from widely using this farming method in practice.

[0014] As a result, among smaller farmers with limited labor and economic scale, there is a lack or complete absence of methods for activating root respiration in soil-grown and hydroponic crops through low-cost and simple means.

[0015] To date, the existing technologies disclosed as oxygen farming methods for achieving oxygenated root respiration in crop cultivation processes via soil and hydroponics are as follows:

[0022] Korean Patent Application Publication No. 10-2017-0047422 proposes a deep liquid flow technology system that can adjust the amount of dissolved oxygen.

[0023] Korean Patent Application Publication No. 10-2015-0082577 discloses a hydroponic cultivation machine that combines an ultrafine bubble generating device, including a primary perforated plate and multiple secondary perforated plates, with a hydroponic container, thereby including an ultrafine bubble generating device that can utilize ultrafine bubble oxygen to dissolve water in the hydroponic container.

[0024] Korean Patent Application Publication No. 10-2014-0093075 discloses a ginseng hydroponic water tank device. The device has a seedbed fixing device and a nano bubble generating device at the upper end of the four sides of the hydroponic water tank to create a three-level curved section to prevent the water tank from bending due to the weight of the fresh water in the water tank.

[0025] The present invention is a new oxygen farming method that confirms a previously undisclosed method for increasing yield and income in existing technologies. In soil or hydroponics, oxygen is supplied to the crop roots at any necessary time during crop cultivation. Alternatively, diluted salt-based oxygen-generating catalysts and diluted peroxide sources are individually supplied to the soil surface in containers such as ringers connected to drainage lines. These components are slowly supplied to the crops that rely on oxygen for root respiration, thereby activating the basal metabolic activities of the oxygen-supplied crops. This provides a stable and active farming method that allows the crops to maintain a balanced underground growth, resulting in healthy roots, reduced labor and production costs, increased yields, and higher farmer incomes. Summary of the Invention

[0026] The technical issues to be solved

[0027] The oxygen concentration required for root respiration for basic crop growth should ideally be maintained at 12 ppm or higher. However, the dissolved oxygen concentration in most crop cultivation water is maintained below 5 ppm. Therefore, crops need water with high dissolved oxygen content for normal growth. As the temperature rises or the surrounding environment changes, the dissolved oxygen content in the water will decrease, and the dissolved oxygen near the roots will be insufficient. This leads to metabolic disorders due to decreased respiration, resulting in stunted growth. Therefore, the present invention has developed a functional composition that can provide oxygen for a long time to solve the problem of stunted growth caused by metabolic disorders due to insufficient respiration.

[0028] The purpose of this invention is to provide an oxygen-producing functional composition and a farming method using the composition. In soil cultivation and hydroponics, when crop roots require oxygen, the composition and farming method maximize the amount of oxygen needed for root respiration, a basic requirement for plants, through simple and convenient means. This increases the marketability and yield of crops, reduces production costs, and compared with existing agriculture, not only increases farmers' income but also enables a crop oxygen farming method that can resist pests and diseases and provide crops with an improved growing environment through long-term oxygen supply.

[0029] Methods for solving problems

[0030] The technical objective of this invention is to provide an oxygen-producing functional composition for crop cultivation as a means to achieve the stated objective. This composition, in both soil and hydroponics, achieves oxygen agriculture by maximizing the amount of oxygen required for root respiration. The technology utilizes an inorganic compound selected from aluminum (Al), titanium (Ti), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and tungsten (W), along with one of sulfate, chloride, nitrate, acetate, phosphate, or fluorinating agent, each of which is individually formulated to dissolve in storage water to 0. Solution A, consisting of an oxygen-generating catalyst composition with a concentration of 0.05-25% by weight, and solution B, consisting of an oxygen composition dissolved in water with hydrogen peroxide (H2O2) or persulfate to a concentration of less than 50% by weight, are used. For example, in order to apply oxygen farming to small crops such as vegetables, solution A, consisting of an oxygen-generating catalyst in the form of a metal salt (Salt) diluted to a concentration of 10ppm-900ppm, is sprayed into the water of soil-grown or hydroponic plots by a single supply method. Then, immediately or after a certain period of time, when the roots of the crops need to respire, solution B, consisting of hydrogen peroxide (H2O2) or persulfate, can be supplied as an oxygen source after being diluted to a concentration of 25ppm-5,000ppm.

[0031] In another embodiment, for crops such as apples, peaches, and pears that are large in size and widely spaced, when applying oxygen farming, solutions A and B have the same composition. Solution A is diluted to a concentration of 10ppm-900ppm and stored in a container (A-1) equipped with drainage pipes and discharge devices. Solution B is diluted to a concentration of 25ppm-5,000ppm and stored in a container (B-1) equipped with drainage pipes and discharge devices, and used as method D for spraying on the crop cultivation area, thereby realizing oxygen farming and achieving high-yield cultivation.

[0032] The technical objective of this invention is to maximize the oxygen demand required for crop root respiration, thereby achieving oxygen farming and high-yield cultivation.

[0033] An inorganic compound selected from aluminum (Al), titanium (Ti), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and tungsten (W), combined with a salt in the form of sulfate, chloride, nitrate, acetate, phosphate, fluoride, or a chelating agent, constitutes solution A of a dissolved oxygen-generating catalyst composition dissolved in storage water to a concentration of 0.05-25% by weight. This solution contains hydrogen peroxide (H₂O₂) or persulfate (Per... Solution B is an oxygen-generating composition dissolved in water to a concentration of less than 50% by weight (sulfate). Depending on the crop cultivation environment, solution A is first diluted to a concentration of 10ppm-900ppm and sprayed, and then solution B is diluted to a concentration of 25ppm-5,000ppm and used as method C for spraying on the crop cultivation area. Alternatively, depending on the crop cultivation environment, solution A is diluted to a concentration of 10ppm-900ppm and stored in a container (A-1) equipped with a drainage pipe and discharge device, and solution B is diluted to a concentration of 25ppm-5,000ppm and stored in a container (B-1) equipped with a drainage pipe and discharge device and used as method D for spraying on the crop cultivation area, thereby realizing oxygen farming of crops.

[0034] Insecticides, fungicides, fertilizers, and nutrients selected as ingredients required for crop cultivation are added to the A or B solution composition used in this invention, thereby enabling oxygen-based farming of crops and achieving high-yield cultivation.

[0035] When obtaining the salt bound to the chelating agent, it is obtained from ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), ethylenediamine-N,N′-bis(2-hydroxyphenylacetic acid), nitrilitriacetic acid (NTA), cyclohexadiamine tetraacetic acid (CyDTA), trisodium ethylenediaminedisuccinate (EDDS), methylglycinediacetic acid (MGDA), ethylene glycol diethyl ether diaminetetraacetic acid (EGTA), and 1,2-cyclohexanediaminetetraacetic acid (DCTA). The chelating agent is selected from one or more of the following: glutamic acid, tetrasodium glutamate diacetate (GLDA), aminosuccinic acid (IDS), fumaric acid, lactic acid, citric acid, malic acid, butyric acid, formic acid, propionic acid, ascorbic acid, amino acids, fulvic acid, humic acid, carboxylic acid, thioctic acid, sulfonic acid, and sulfamic acid.

[0036] The persulfate may be selected from ammonium persulfate, sodium persulfate, or potassium persulfate.

[0037] Invention Effects

[0038] As explained in the background section above, this invention, during crop cultivation, can supply oxygen to the soil in soil-grown areas or the water in hydroponic areas in any form as needed for a long period of time, thereby increasing the oxygen concentration. Ultimately, this leads to vigorous root growth, enhanced root nutrient absorption, increased photosynthetic products, and vigorous crop growth energy, resulting in vigorous fruit growth. This minimizes farmers' labor costs while improving crop marketability, yield, and disease and pest resistance, thus potentially ensuring economic benefits and enhancing farmers' technological competitiveness.

[0053] Example 4

[0054] A 0.5% by weight solution of ferric citrate and a 50% by weight solution of ammonium persulfate were prepared as oxygen-generating compositions for hydroponics.

[0055] Dilute 0.5% by weight of ferric citrate storage solution to a concentration of 250 ppm. After uniformly supplying the diluted ferric citrate to a 330 m² hydroponic plot of fully ripe tomatoes, immediately dilute ammonium persulfate to a concentration of 1000 ppm. As a regular supply source to ensure the quality and quantity of crops during the fully ripe tomato cultivation period, mix Agrossol liquid fertilizer [Agrobiz AG] with a nitrogen-phosphate-potassium concentration ratio of 20-20-20% by weight into a 10 ppm hydrogen peroxide solution, and continuously supply this mixture to the hydroponic plot at a rate of approximately 2.5 ml per minute.

[0056] At this point, the cultivation period for fully ripe tomatoes is 5 months. In order to compare the effects brought about by the technical purpose of this invention, the average weight of 500 fully ripe tomatoes harvested in 5 months was determined.

[0057] Example 5

[0058] A storage solution of 25% by weight of zinc acetate trihydrate [Tri-electric purified material, Zn(CH3CO2)2·3H2O] was prepared as an oxygen-generating catalyst composition, and a storage solution of 50% by weight of sodium persulfate [Tri-electric purified material, sodium sulfite] was prepared as an oxygen-generating composition.

[0059] Dilute the zinc acetate trihydrate storage solution with water to a concentration of 900 ppm, and fill the diluted zinc acetate trihydrate solution into a 1-liter container connected to the drain line. Fill the sodium persulfate solution with a concentration of 5000 ppm into a 1-liter container connected to another drain line.

[0060] Containers filled with zinc acetate trihydrate solution and containers filled with hydrogen peroxide were suspended on the trunks of 20 apple trees. Zinc acetate trihydrate solution diluted to 900 ppm and sodium persulfate solution diluted to 5,000 ppm were applied to the apple tree surface at a rate of 5 ml per minute. Starting from early March (March 2nd), during the apple tree infusion movement period (the period of water absorption from the soil), the soil was supplied seven times every three days during the apple cultivation period. As a regular source of supply to ensure apple quality and quantity, 1 kg of Agrossol liquid fertilizer [Agrobiz AG] with a nitrogen-phosphorus-potassium ratio of 20-20-20% by weight was diluted with water and applied to the 20 apple trees every five days.

[0061] At this time, the apple cultivation period was 8 months, and in order to compare the effects brought about by the technical purpose of this invention, the average weight of 20 Fuji apple trees was determined.

[0062] Comparative Examples 1-5

[0063] During crop cultivation, the process was carried out in the same manner as in Examples 1-5, except that the oxygen-generating catalyst composition and the oxygen-generating composition of hydrogen peroxide and even persulfate were not supplied to the crop cultivation site.

[0064] The results of Comparative Examples 1-5 and Examples 1-5 are shown in Table 1.

[0065] Table 1

[0066]

[0067] As shown in Table 1, in Comparative Examples 1-5, where the possibility of root respiration via oxygen is low due to the presence of trace amounts of oxygen in the soil and water, the average weight of watermelon was 7.68 kg, the average weight of a single white fruit plant was 4.23 kg, the average weight of a single bunch of grapes was 294 g, the average weight of a single ripe tomato was 262 g, and the average weight of a single apple was 476 g.

[0068] Conversely, as shown in Examples 1-5, it is known that when oxygen is supplied to the soil and water for soil cultivation and hydroponics, the roots of plants growing in the soil receive sufficient oxygen during respiration, thereby significantly increasing the average weight of watermelons to 10.4 kg, the average yield of cabbage to 5.74 kg per plant, the average weight of grapes to 363 g per bunch, the average weight of ripe tomatoes to 284 g, and the weight of apples to 504 g.

[0069] Furthermore, according to the technical solution for soil oxygenation of the present invention, when the oxygen-generating catalyst composition is sprayed onto the soil immediately or after spraying, and after an appropriate date, the oxygen source can be supplied to the soil as needed and without time restrictions. Based on the oxygen-generating catalyst composition of metal salt already present in the soil, sprayed hydrogen peroxide or persulfate as an oxygen-generating composition, or filling a container connected to a drainage line with the oxygen-generating catalyst composition of metal salt and the oxygen-generating composition of hydrogen peroxide or persulfate respectively, and through the drainage pipe of the container and by means of slowly discharging to the soil surface of the crop cultivation area, the composition of metal salt, hydrogen peroxide, and persulfate is infiltrated into the soil. Simultaneously, through a mixing process and through the chemical reaction of hydrogen peroxide and even persulfate, oxygen is stably supplied to the soil for a long period, thereby increasing the possibility of high-yield and high-quality crops by activating root respiration. This minimizes labor while improving crop growth and increasing productivity, and therefore is expected to make a significant contribution to ensuring farmers create economic benefits and enhance their technological competitiveness.
