Description

[Technical Field]

[0001] The present invention relates to an oxygen-generating composition capable of supplying oxygen to crop cultivation areas for a long period of time, and a farming method using the same, for implementing oxygen farming for crops, which can maximize root approach and growth activity by providing sufficient oxygen when roots of plants growing in soil or water breathe during the process of cultivating crops using soil or nutrient solution culture, thereby improving crop quality and yield. [Background technology]

[0002] During the process of cultivating crops, roots develop and grow in relation to the air (oxygen) and temperature in the soil, and root respiration, enzyme activity, microbial activity, and the activity of root fungi are all closely related to the air in the soil.

[0003] Trees generally have deep roots, which means that they cannot develop as well as fine roots on the surface due to poor air circulation. Therefore, it is important to encourage the development of fine roots deep underground as well as on the surface to grow trees healthily.

[0004] In addition, the amount and circulation of air in the soil is extremely important for emitting carbon monoxide above ground, which is produced by root respiration and the decomposition of organic matter, and for smooth supply of oxygen.

[0005] If a plant wants to grow strong, it needs strong roots, and if the plant roots are to grow strong, they need not only adequate nutrients and water but also oxygen.

[0006] Although it is easy to overlook, plants breathe not only through their leaves but also through their roots, and plants can only grow well if their roots breathe smoothly. When growing plants in soil, a method is used in which thick white perlite particles are mixed in to create air holes for good drainage.

[0007] Furthermore, in hydroponic cultivation, where the roots are submerged in water, oxygen deficiency is even more likely to occur, so it is important to always pay attention to the oxygen supply.In particular, in the summer, when the temperature of the nutrient solution rises, the plants' ability to absorb oxygen decreases, so it becomes even more important to provide a good oxygen supply.

[0008] The minimum oxygen concentration required for crops to grow is 5 ppm, so it must not be lower than this. The energy required for plant root development is obtained through respiration, which is what drives growth and physiological functions. If there is a lack of dissolved oxygen near the roots, the rate of respiration will drop sharply, causing metabolic disorders and stunted growth. In particular, the higher the temperature, the more vigorous the plant's growth and the greater the oxygen demand for nutrient absorption. In comparison, the higher the temperature, the more vigorously the plant grows and the greater the oxygen demand for nutrient absorption. Therefore, the dissolved oxygen concentration in the supply water will drop sharply, becoming a limiting factor for growth.

[0009] If the dissolved oxygen concentration is not increased and the treatment continues for 2-3 hours, the dissolved oxygen will be depleted and fall below 2 ppm, which may cause the plants to die. However, if sufficient dissolved oxygen is supplied, the supply of nutrients and water to the plants will be smooth, which will improve the growth of the plants and result in improved quality and an increase in production volume by more than 20%.

[0010] For this purpose, oxygen farming must supply the root respiratory oxygen demand of 20 ppm or more, which is the basic requirement of crops, to maximize the catabolic / biochemical processes that are the metabolic processes of crops, and thereby maximize the energy efficiency of photosynthesis. This must provide more than twice the root growth energy to the underground roots, which are the most important condition for the vegetative and reproductive growth of crops, compared to existing farming methods (13:3:0), thereby maximizing root establishment in soil and water and ensuring their longest lifespan.

[0011] If the soil and water used in soil and hydroponics are rich in root oxygen, it is necessary to find a way to significantly improve the growing environment for crops, including those used in soil and hydroponics, by optimizing root respiration and establishment, maximizing catabolism, assimilation, and biochemical processes, maximizing nutrient or water absorption rates, normalizing metabolic processes, strengthening crop resistance, reducing top dressing and pesticide use, maximizing the stabilization of crop growth, increasing production and marketability, overcoming and eliminating salt accumulation, and overcoming and eliminating gas damage and continuous crop damage.

[0012] In addition, if root oxygen is deficient, it can lead to poor root establishment and reduced water absorption, metabolic disorders in the roots, reduced catabolism, assimilation, and biochemical functions, nutrient loss, excessive fertilization, salt accumulation, and reduced resistance to pests, which can prevent crops from growing properly.It is also important to consider the problem that increased ethylene production can lead to root death.

[0013] Therefore, oxygen farming increases the marketability and production of crops by restoring the fundamental and intrinsic vitality and vitality of the underground roots and the above-ground leaves, stems and seedlings of soil-grown and hydroponically grown crops, and also makes the crops resistant to diseases and pests. It is recognized that soil root oxygen is very important for farmers to grow crops. However, due to a lack of technology, oxygen supply technology for crop root respiration is insufficient or requires a lot of expense, so it is not widely used by farmers.

[0014] As a result, there are few or no methods for activating root respiration of crops for soil cultivation and hydroponic cultivation in a simple and inexpensive manner for farms with small labor and economic scale.

[0015] The prior art disclosed so far for implementing oxygen farming for root respiration of oxygen in the process of cultivating crops through soil cultivation and nutrient solution cultivation is as follows.

[0016] Korean Patent Publication No. 10-2020-0031826 discloses an oxygen-generating mineral fertilizer that includes a zeolite mass at the center, a decomposition catalyst, a calcium peroxide inner layer surrounding the outer surface of the zeolite mass, and a slag outer layer surrounding the outer surface of the calcium peroxide inner layer.

This catalyst has electrochemical reaction activity suitable for water electrolysis and significantly improves catalytic stability under acidic high-potential conditions.

[0021] Korean Patent Publication No. 10-2020-0143784 discloses an oxygen generator that uses homogeneous intake air, and Korean Patent Publication No. 10-2017-0008933 discloses an oxygen generator composition that is composed of 30 to 60 wt% of a mixture of oxygen-generating substances, potassium peroxide (K2O2), potassium superoxide (KO2), and sodium peroxide (Na2O2), and 40 to 70 wt% of one or more reaction modifiers selected from activated carbon, zeolite, and silicon dioxide, and that contains 1 to 3 times the content of one or more neutralizers selected from the group consisting of citric acid, potassium phosphate, glutamic acid, ascorbic acid, tartaric acid, salicylic acid, glycolic acid, lactic acid, glycyrrhizic acid, and aminocaproic acid.

[0022] Korean Patent Publication No. 10-2017-0047422 proposes a flooded hydroponic system that can adjust the amount of dissolved oxygen.

[0023] Korean Patent Publication No. 10-2015-0082577 discloses a hydroponic cultivation machine including an ultrafine bubble generator that can utilize ultrafine bubble oxygen-dissolved water for hydroponic cultivation by combining the ultrafine bubble generator, which includes a primary perforated plate and a plurality of secondary perforated plates, with a hydroponic cultivation container.

[0024] Korean Patent Publication No. 10-2014-0093075 discloses a tank device for hydroponic cultivation of ginseng, which has a pad fixing device and a nanobubble generator, and which has three bends on the top four sides of the tank to prevent the tank from bending due to the weight of fresh water in the tank.

[0025] However, in the above-mentioned prior art, oxygen is supplied to the roots of crops at any desired time during the process of cultivating crops in soil or hydroponics, as in the present application. Alternatively, a composition of an oxygen generating catalyst in a salt state diluted with water and a diluted peroxide source is individually filled in a container such as a Ringer bottle connected to a drainage line on top of the soil. The oxygen generating catalyst and the diluted peroxide source composition are individually and gradually supplied to the soil of crops that require oxygen-assisted root respiration, thereby activating the basal metabolic activity of the crops through oxygen supply and allowing the crops themselves to maintain a normal underground growth balance. This provides a stable and active farming method, provides healthy roots, reduces labor and production costs, increases yields, and improves farmer income. This is a new technology that has been developed based on the recognition that no technology has been disclosed to implement oxygen farming. [Prior art documents] [Patent documents]

[0027] The oxygen requirement for root respiration, the basic growth activity of crops, is preferably maintained at a concentration of 12 ppm or more. However, the amount of dissolved oxygen contained in the water supplied for most crop cultivation is maintained at an average concentration of 5 ppm or less. Therefore, water with a high dissolved oxygen content is necessary for normal growth of crops. However, the amount of dissolved oxygen in water decreases as the temperature rises or the surrounding environment changes. If the amount of dissolved oxygen around the roots becomes insufficient, the respiration rate decreases, causing metabolic disorders and stunted growth. This technology was developed in recognition of the need for a functional composition that can supply oxygen for a long period of time to eliminate this concern.

[0028] The present application aims to provide an oxygen generating composition capable of supplying oxygen for a long period of time to realize oxygen farming for crops that provides an improved growing environment for crops while providing resistance to pests and diseases, by maximizing the oxygen demand of root respiration that plants basically require in a simple and convenient manner when oxygen supply to crop roots is required in soil cultivation and hydroponic cultivation processes, thereby increasing the marketability and yield of crops and reducing production costs, thereby increasing farmers' income compared to conventional agriculture. It also aims to provide a farming method using the same. [Means for solving the problem]

[0029] The technical idea disclosed in the present application as a means for achieving the above object is a technology for providing an oxygen-generating functional composition for crop cultivation to realize oxygen farming by maximizing the root respiratory oxygen demand of crops in soil cultivation and nutrient solution cultivation processes. The oxygen-generating functional composition is an oxygen-generating functional composition for crop cultivation, which is an oxygen-generating functional composition for crop cultivation ... Solution A, which stores a generating catalyst composition, and solution B, which stores an oxygen generating composition in which hydrogen peroxide (H2O2) or persulfate is dissolved in water at a concentration of 50 wt% or less, are separately composed. For example, in order to apply oxygen farming to relatively small crops such as vegetables, solution A, which is made of an oxygen generating catalyst in a metal salt state diluted to a concentration of 10 ppm to 900 ppm, is applied by being sprayed into the water of a soil cultivation area or a nutrient solution cultivation area using a primary supply means. When root respiration of crops is required, either immediately or after a certain period of time, solution B, which is an oxygen source composition of hydrogen peroxide (H2O2) or persulfate, can be applied by being diluted to a concentration of 25 ppm to 5,000 ppm and supplied.

[0030] In another embodiment, when oxygen farming is desired for crops that are large in size and spaced apart, such as apples, peaches, and pears, the components of Solution A and Solution B are equal, and Solution A is diluted to a concentration of 10 ppm to 900 ppm and stored in a container (A-1) equipped with a drainage line and discharge means, and Solution B is diluted to a concentration of 25 ppm to 5,000 ppm and stored in a container (B-1) equipped with a drainage line and discharge means, and then sprayed on the crop cultivation area. This invention was completed after confirming that oxygen farming can be realized for crops, resulting in high-yield cultivation.

[0031] Therefore, the technical idea of ​​the present application is a farming method that maximizes the oxygen demand required for root respiration of agricultural crops, realizes oxygen farming, and enables high-yield cultivation. A solution A contains an oxygen generating catalyst composition in which an inorganic material selected from aluminum (Al), titanium (Ti), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and tungsten (W) is dissolved in water at a concentration of 0.05 to 25 wt% in the form of sulfate, chloride, nitrate, acetate, phosphate, fluoride, or a salt combined with a chelating agent, and hydrogen peroxide (H2O2) or persulfate is dissolved in water at a concentration of 50 wt% or less. Solution B, in which the generating composition is stored, is individually prepared, and Solution A is first diluted to a concentration range of 10 ppm to 900 ppm and sprayed on the soil according to the crop cultivation environment, and then Solution B is diluted to a concentration of 25 ppm to 5,000 ppm and sprayed on the crop cultivation area (Method C), or Solution A is diluted to a concentration of 10 ppm to 900 ppm according to the crop cultivation environment, stored in a container (A-1) equipped with a drainage line and discharge means, and Solution B is diluted to a concentration of 25 ppm to 5,000 ppm, stored in a container (B-1) equipped with a drainage line and discharge means, and sprayed on the crop cultivation area (Method D), thereby realizing oxygen farming of crops and enabling high-yield cultivation.

[0032] Of course, the A or B solution composition used in the present technology may be further applied with an ingredient required for crop cultivation selected from insecticides, fungicides, fertilizer ingredients, and nutrients, thereby realizing oxygen farming of agricultural crops and enabling high-yield cultivation.

[0033] When obtaining the salt bound with the chelating agent, the chelating agent may be Ethylene-diamine-tetraacetic acid (EDTA), Diethylenetriamine pentaacetic acid (DTPA), EDDHA (Ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid), Nitrilitriacetic acid (NTA), 1,2-cyclohexadiamine tetraacetic acid (CyDTA), Ethylenediaminedisuccinic acid (EDDS), Methylglycinediacetic acid (MGDA), Ethyleneglycoltetraacetic acid (EGTA), Ethyleneglycoltetraacetic acid (DCTA), Glutamic aciddiacetic acid (GLDA), Aminodisuccinic acid (IDS), or Fumaric acid. One or more chelating agents selected from the group consisting of lactic acid, citric acid, malic acid, butyric acid, formic acid, propionic acid, ascorbic acid, amino acids, fulvic acid, humic acid, carboxylic acid, sulfinic acid, sulfonic acid, and sulfamic acid may be used.

[0034] The persulfate may be selected from the group consisting of ammonium persulfate, sodium persulfate, and potassium persulfate. [Effects of the Invention]

[0035] As explained in detail above, as clarified in the background art, the present application increases the oxygen concentration by supplying oxygen to the soil of soil cultivation areas or the water of nutrient solution cultivation areas over a long period of time as needed during the process of cultivating crops, thereby resulting in vigorous root growth, increased root nutrient absorption, increased photosynthetic products, and vigorous crop growth energy, thereby promoting vigorous fruit growth of crops. This is expected to minimize the labor required by farmers, improve the marketability of crops, increase production, and increase resistance to diseases and pests, thereby generating economic benefits for farmers and ensuring their technological competitiveness.

[0040] The watermelons were grown for 120 days, and the average weight of 450 harvested watermelons was measured to compare the effectiveness of the present invention's technical concept.

[0041] Example 2 A stock solution of 25 wt% iron chloride hexahydrate (Samjeong Sunyak, FeCl3·6H2O) was prepared as an oxygen generating catalyst composition, and a stock solution of 35 wt% hydrogen peroxide (Daemyung Chemical, H2O2) was prepared as an oxygen generating composition. The iron chloride hexahydrate stock solution was diluted with water to a concentration of 10 ppm, and the diluted iron chloride hexahydrate solution was used for growing Chinese cabbage at 660 ml. 2After sprinkling the mixture evenly over the greenhouse soil, a diluted hydrogen peroxide solution at a concentration of 25 ppm was immediately sprinkled evenly over the soil. The oxygen generating composition for cultivated soil for Chinese cabbage cultivation was supplied to the soil at 13-day intervals during the Chinese cabbage cultivation period. 1 kg of Agrosol liquid fertilizer (Agrobiz Co., Ltd.), which is a common supply source for ensuring the quality and quantity of Chinese cabbage during the Chinese cabbage cultivation period and has a nitrogen-phosphate-potassium concentration ratio of 20-20-20% by weight, was diluted with water and applied to the soil at 330 ml every 3 days. 2 was irrigated.

[0042] Example 3 A stock solution of 25 wt % copper nitrate trihydrate [Samjeong Sunyak, Cu(NO3)2·3H2O] was prepared in the oxygen generating catalyst composition, and a stock solution of 35 wt % hydrogen peroxide (Daemyung Chemical, H2O2) was prepared in the oxygen generating composition.

[0043] A stock solution of copper nitrate trihydrate was diluted with water to a concentration of 500 ppm, and the diluted copper nitrate trihydrate solution was filled into a 1-liter container connected to a drain line, and another 1-liter container connected to a drain line was filled with hydrogen peroxide at a concentration of 2,000 ppm.

[0044] A container filled with copper nitrate trihydrate solution and a container filled with hydrogen peroxide were hung on the stems of 20 grapevines, and the copper nitrate trihydrate solution diluted to 500 ppm and hydrogen peroxide at 2,000 ppm concentration were discharged to the surface of the vines at a rate of 5 ml per minute, respectively. These were supplied to the soil at equal intervals of 3 days throughout the grape growing period. 1 kg of Agrosol liquid fertilizer (Agrobiz Co., Ltd.), which is a common source of fertilizer for ensuring the quality and quantity of grapes during the grape growing period and has a nitrogen-phosphate-potassium concentration ratio of 20-20-20% by weight, was diluted with water and applied to the soil at 330 ml every 3 days. 2 was irrigated.

[0045] The grape cultivation period was 150 days, and the average weight of Campbell grapes for 20 vines was measured to compare the effects of the present invention's technical concept.

[0046] Example 4 Oxygen-generating compositions for hydroponics were prepared by separately preparing a 0.5 wt% ferric citrate (Samjeongsunyak) stock solution and a 50 wt% ammonium persulfate (Samjeongsunyak) stock solution.

[0047] A 5% by weight iron citrate stock solution was diluted to a concentration of 250 ppm, and the diluted iron citrate was added to 330 ml 2 After uniformly supplying the solution to the hydroponic culture area for fully ripe tomatoes, ammonium persulfate was immediately diluted to a concentration of 1,000 ppm. Agrosol liquid fertilizer (Agrobiz Co., Ltd.), a common supply source for ensuring the quality and quantity of crops during the fully ripe tomato cultivation period, with a nitrogen-phosphate-potassium concentration ratio of 20-20-20% by weight, was mixed with a diluted solution of hydrogen peroxide, an oxygen source, to a concentration of 10 ppm, and the mixed solution was continuously supplied to the hydroponic culture area at a rate of approximately 2.5 ml per minute.

[0048] In this case, the period for cultivating the ripe tomatoes was 5 months, and the average weight of 500 ripe tomatoes harvested over a 5-month period was measured to compare the effects of the technical concept of the present invention.

[0049] Example 5 A stock solution of 25 wt% zinc acetate trihydrate (Zn(CHCO)3H0) was prepared as an oxygen generating catalyst composition, and a stock solution of 50 wt% sodium persulfate (Sodium persulfate) was prepared as an oxygen generating composition.

[0050] A stock solution of zinc acetate trihydrate was diluted with water to a concentration of 900 ppm, and the diluted zinc acetate trihydrate solution was filled into a 1-liter container connected to a drain line, and another 1-liter container connected to a drain line was filled with a 5,000 ppm sodium persulfate solution.

[0051] Containers filled with zinc acetate trihydrate solution and hydrogen peroxide were hung from the stems of 20 apple trees, respectively, and a zinc acetate trihydrate solution diluted to 900 ppm and a sodium persulfate solution at a concentration of 5,000 ppm were each adjusted to be discharged onto the surface of the apple trees at a rate of 5 ml per minute. These solutions were supplied to the soil at three-day intervals seven times throughout the apple-growing period, starting in early March (March 2), which is the apple tree's sap movement period (the period when water is absorbed from the soil). 1 kg of Agrosol liquid fertilizer (Agrobiz Co., Ltd.), a common source of fertilizer for ensuring the quality and quantity of apples during the apple-growing period, with a nitrogen-phosphate-potassium concentration of 20-20-20% by weight, was diluted with water and irrigated to the 20 apple trees at five-day intervals.

[0052] The apples were grown for eight months, and the average weight of Fuji apples was measured on 20 apple trees to compare the effectiveness of the technical concept of the present invention.

[0053] Comparative Examples 1 to 5 The same procedures as in Examples 1 to 5 were carried out, except that the oxygen generating catalyst composition and the oxygen generating composition of hydrogen peroxide or persulfate were not supplied to the crop cultivation area during the period when the crops were cultivated.

[0054] The results of Comparative Examples 1 to 5 and Examples 1 to 5 are shown in Table 1.

[0055] [Table 1]

[0056] As shown in Table 1, in Comparative Examples 1 to 5, where there was very little oxygen in the soil and water and the possibility of root respiration due to oxygen was low, the average weight of the watermelon was 7.68 kg, the average weight of the Chinese cabbage was 4.23 kg per piece, the average weight of the grapes was 294 g per bunch, the average weight of the fully ripe tomatoes was 262 g per piece, and the average weight of the apples was 476 g.

[0057] Meanwhile, when oxygen is supplied to the soil and water for soil cultivation and hydroponics as in Examples 1 to 5, sufficient oxygen supply during root respiration of plants growing in the soil promotes root growth and development activity, resulting in a significant increase in the average weight of watermelons to 10.4 kg, an average weight increase of 5.74 kg per cabbage, an average weight increase of 363 g per bunch of grapes, an average weight increase of 284 g for ripe tomatoes, and an apple crop weighing 504 g for Fuji apples.

[0058] In addition, in the technical means for supplying oxygen to soil according to the present invention, when an oxygen source that can be an oxygen source is supplied to the soil immediately after the oxygen generating catalyst composition is sprinkled on the soil or after the sprinkling, if necessary, at an appropriate time regardless of the time, the oxygen generating catalyst composition of metal salt already present in the soil is sprayed by a supply means of hydrogen peroxide or persulfate that will later supply the oxygen generating composition, or the metal salt is added to a container connected to a drainage line. The oxygen generating catalyst composition of metal salt and the oxygen generating composition of hydrogen peroxide or persulfate are individually filled and gradually discharged onto the soil surface through the drainage line of the container. As the metal salt and hydrogen peroxide or persulfate composition soak into the soil and mix, the chemical reaction of hydrogen peroxide or persulfate provides a stable supply of oxygen in the soil over the long term, activating root respiration and potentially enabling the production of high-quality crops. It is expected to significantly contribute to the creation of economic benefits for farmers and the securing of their technological competitiveness by improving crop growth and increasing productivity while minimizing labor.
