Description

Oxygen-generating functional composition that can supply oxygen to crop fields for a long time and farming method using the same

The present invention improves the quality and production of crops by maximizing root attachment and developmental activity by supplying sufficient oxygen when the roots of plants growing in soil and water breathe during the process of cultivating crops by soil cultivation and nutrient solution cultivation. This is an invention in the field of technology related to an oxygen-generating functional composition that can supply oxygen to crop fields for a long time and a farming method using the same in order to implement oxygen farming for crops.

During the process of cultivating crops, the rooting and growth of roots is related to the air (oxygen) and temperature in the soil, and the respiration of the roots, the activity of enzymes and microorganisms, and the action of root fungi are closely related to the air in the soil. there is.

Since trees generally have deep roots, air circulation is poor and they do not develop as well as the fine roots on the surface. Therefore, it is important to foster the trees soundly by encouraging the development of fine roots not only on the surface but also deep underground.

In addition, the amount and distribution of air in the soil are very important in order to discharge carbon monoxide generated through root respiration and decomposition of organic matter above the ground and to facilitate the supply of oxygen.

For plants to grow strong, their roots must be strong, and for plant roots to grow strong, they need not only adequate nutrients and moisture, but also oxygen.

It's an easy part to overlook, but plants also breathe through roots as well as leaves, and root respiration must be smooth for plants to grow well. Even when grown in soil, a method of mixing white perlite with coarse particles to create air holes for good drainage This also applies.

Moreover, in nutrient solution cultivation, where the roots are submerged in water, it is more likely to become deficient in oxygen, so it is important to always pay attention to oxygen supply. Especially in summer, when the temperature of the nutrient solution rises, the plant's ability to absorb oxygen decreases, so it is necessary to ensure a good supply of oxygen. becomes more important.

The minimum oxygen concentration required for crop growth is 5 ppm, so it should not be lower than this. The energy required for plant root development is the energy obtained through respiration for growth and physiological functions, so if the amount of dissolved oxygen near the roots is insufficient, a rapid decrease in respiration can occur. As a result, metabolic disorders occur and growth is reduced. In particular, at higher temperatures, plants grow more vigorously and oxygen requirements increase for nutrient absorption, but the dissolved oxygen concentration in the supplied water rapidly decreases, becoming a limiting factor for growth.

At this time, if the dissolved oxygen concentration is not increased and continued for 2 to 3 hours, dissolved oxygen will be depleted and there is a risk of death if it falls below 2 ppm. However, if dissolved oxygen is sufficiently supplied, nutrients and moisture supply to the crop will be smooth. The growth of crops improves, resulting in improved quality and increased production by more than 20%.

Oxygen farming for this purpose maximizes the catabolic/biochemical functions of the crop's metabolism by supplying 20 ppm or more of the basic oxygen requirement for root respiration and thereby maximizing the energy efficiency of photosynthesis. , By supplying more than twice the root growth energy to the underground roots, which is the most important condition for the nutritional and reproductive growth of crops, compared to the existing farming method (13:3:0), maximizing root establishment in the soil and water and the longest lifespan A plan to guarantee is required.

If root oxygen in the soil and water is abundant during soil cultivation and nutrient solution cultivation, optimization of root respiration and rooting, maximization of catabolism, assimilation, and biochemistry, maximization of nutrient or water absorption, normalization of metabolism, strengthening of crop resistance, and additional fertilization. and reduction of the use of pesticides, maximum stabilization of crop development status, increase in production and marketability, overcoming and resolving salt accumulation phenomenon, overcoming and resolving gas disturbances and continuous cropping disturbances, and improving the growth environment of soil cultivation and nutrient solution cultivation, as well as crop growth. A plan is needed to significantly improve the growing environment.

In addition, if root oxygen is deficient, root survival is slowed, water absorption is reduced, metabolic disorders in the roots occur, and catabolism occurs. Problems that must be taken into consideration include low assimilation and biochemical activity, resulting in nutrient loss, excessive fertilization, salt accumulation, and low disease and pest resistance, which can cause crops to not grow properly, as well as cause root death due to increased ethylene production.

Therefore, oxygen farming increases the marketability and production of crops by providing fundamental and natural vitality and vitality to the underground roots and above-ground leaves, stems, and fruit growth of crops cultivated in soil and nutrient solution, and further increases their own resistance to diseases and pests. It is recognized that root oxygen in the soil is very important when growing crops for farmers. However, due to lack of technology, oxygen supply technology for root respiration of crops is insufficient or requires a lot of expense, making it virtually impossible to use. The reality is that it is not widely used by farmers.

As a result, there is little or no method for activating root respiration of crops for soil cultivation and nutrient solution cultivation by simple methods at low cost in farms with small labor force and economic scale.

The prior technologies disclosed so far to implement oxygen farming for root respiration during the cultivation process of crops through soil cultivation and nutrient solution cultivation are as follows.

An oxygen generator composition is presented, which is characterized in that it contains 1 to 3 times the amount of the mixture with one or more neutralizing agents selected from the group consisting of silicic acid and aminocaproic acid.

Korean Patent Application No. 10-2017-0047422 proposes a liquid aquaponic system that can control the amount of dissolved oxygen.

In Korean Patent Application No. 10-2015-0082577, an ultra-fine bubble generating device including a primary porous plate and a plurality of secondary porous plates is combined with a hydroponic cultivation container to use ultra-fine bubble oxygen dissolved water for hydroponic cultivation. A hydroponic cultivator including an ultra-fine bubble generating device is presented.

In Korean Patent Application No. 10-2014-0093075, a ginseng plant with a bed fixing device and a nanobubble generating device is created by creating a three-stage bending area on the top of the four sides of the hydroponic cultivation tank to prevent the tank from bending due to the weight of fresh water in the tank. A water tank device for hydroponic cultivation is presented.

However, in the above-described prior art, oxygen is supplied to the crop roots at a randomly selected necessary time during the process of cultivating crops in soil cultivation or nutrient solution cultivation, as in the present invention, or oxygen is generated in a salt state diluted with water in the upper part of the soil. The composition of the catalyst and the diluted peroxide source is configured to be individually filled in a container shaped like a Ringer bottle connected to a drainage line, and the oxygen generating catalyst and the diluted composition are used for crops that require root respiration by oxygen. The composition of the peroxide source is gradually supplied to the soil individually, activating the basic metabolic activity of the crop by supplying oxygen, and providing a stable and active farming method to maintain normal growth balance in the underground part of the crop itself. This is a new technology developed after confirming that there has been no known technology for implementing oxygen farming, which reduces labor and production costs by providing roots and improves farm income by increasing yield.

We recommend that the concentration of oxygen required for root respiration, the basic growth activity of crops, be maintained at a concentration of 12 ppm or higher, but the dissolved oxygen contained in water supplied for most crop cultivation is maintained at an average concentration of 5 ppm or less. When growing crops, water with high dissolved oxygen is required for normal growth, but as the temperature rises or the surrounding environment changes, the amount of dissolved oxygen in the water decreases, resulting in a lack of dissolved oxygen near the roots. This technology was developed in recognition of the need for a functional composition that can supply oxygen for a long time as a technology that eliminates the risk of growth retardation due to metabolic disorders due to decreased respiratory rate.

When oxygen supply is needed to the roots of crops during the soil cultivation and nutrient solution cultivation process, our center maximizes the oxygen demand for root respiration, which is fundamentally needed by plants, through simple and convenient means, thereby increasing the marketability and production of crops and reducing production costs. We provide an oxygen-generating functional composition that can supply oxygen for a long time to implement oxygen farming of crops, which not only increases the income of farmers compared to existing agriculture, but also provides an improved growth environment for crops while maintaining resistance to diseases and pests. The purpose is to provide agricultural methods using agricultural methods.

The technical idea disclosed herein as a means to achieve the above objective is a technology for providing an oxygen-generating functional composition for crop cultivation to implement oxygen farming by maximizing the oxygen demand for root respiration of crops during the soil cultivation and nutrient solution cultivation process, Among aluminum (Al), titanium (Ti), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and tungsten (W).

The B solution composition of hydrogen peroxide (H ₂ O ₂ ) or the B solution of the persulfate composition may be applied to be supplied diluted to a concentration of 25 ppm to 5,000 ppm.

In another embodiment, when it is desired to apply oxygen farming to crops such as apples, peaches, and pears that are large in size and have a large distance between the crops, the components of solution A and B are the same, and solution A is mixed with 10 Dilute the solution to a concentration of 25 ppm to 5,000 ppm and store it in a container (A-1) equipped with a drain line and a discharge means, and dilute solution B to a concentration of 25 ppm to 5,000 ppm and store it in a container (B) equipped with a drain line and a discharge means.
