Description

Eco-friendly cultivation method of selenium-containing crops {cultivation method for farm produce contianing selenium}

The present invention relates to a method for cultivating crops to contain selenium, and more particularly to a method for producing selenium-containing crops by an environmentally friendly organic cultivation method.

Selenium is a trace element distributed mainly in the liver, kidneys, heart and spleen and is a component of glutathione peroxidase, a powerful antioxidant enzyme that removes harmful oxygen from the body. By lowering the concentration of peroxide in the cell to prevent the production of free radicals, the enzyme system that acts to prevent the free radicals already produced, the proper amount of selenium can reduce the body's need for vitamin E. Its antioxidant power is 1,970 times that of natural vitamin E (2,940 times that of synthetic vitamin E).

It prevents red blood cells from oxidizing and destroying blood cells, helps to regenerate the liver from cirrhosis, delays aging and prevents mercury poisoning. According to world-renowned reports, including the United States, selenium not only increases immune function against hepatitis and AIDS virus, but also reduces arthritis symptoms and pain and lowers the incidence of cancer by more than 50%.

Severe deficiency in selenium develops severe heart disease and ketosis, which is prevalent in children and women of childbearing age, or in general, increases the risk of cancer, heart disease, and immune dysfunction, and other erythrocyte dysfunction, myalgia, and myocardial degeneration. May lead to muscle tension, pancreatic degeneration. In short, selenium is an essential nutrient for good health.

There are also side effects of overdose, which can lead to hair loss, work sickness, nail loss, and chronic addiction, depression, nervousness, emotional sensitivity, vomiting and nausea. However, in general, acute intoxication due to food intake is rare, and occurs when the dietary supplement tablets are ingested excessively.

Selenium consists of nutritious yeast, seawater, algae, garlic, mushrooms, tuna, bread, ham, eggs, flour, beef and chicken, agricultural products without chemical fertilizers, seafood, milk, eggs, whole grains, almost all It is contained in vegetables, but vegetables and fruits are low in content.

The daily recommended dose of selenium, published by the United Nations Food and Agriculture Organization (FAO) and the World Health Organization (WHO), is 50 to 200 µg for adults, and the recommended intake for cancer prevention is higher than 500 µg. Selenium dosages range from 1000 μg to 2000 μg.

The daily intake of Korean people is known as 43 ㎍, which is less than the minimum recommended amount. For this important reason, the selenium content in grains depends on the soil, and grains grown in Korean soil known as selenium deficiency area have low selenium content. Therefore, Korea's intake of grains as a staple food intake is low, and even if selenium is vulnerable to water overheating, it is easy to lose before metabolism even if it is ingested through vegetables or meat.

As mentioned above, selenium is an organic peroxide in the body along with Superoxide dismutase (SOD) or Catalase as a component of glutathione peroxidase (GPX1) synthesized in the liver. Antioxidant function that inhibits or eliminates the production of hydrogen peroxide to prevent aging and prevent cancer. Iodothyronine deiodinase, a selenium-dependent enzyme, transforms the inactive thyroid hormone T4 secreted from the thyroid gland into the active T3, and selenium directly affects thyroid hormone. In addition, selenium protein (GPX4) is a component of the testicular mitochondrial outer membrane, and selenium is involved in sperm maturation and motility and the production of androgen. It also detoxifies toxic heavy metals such as arsenic, lead and cadmium.

In addition to the intake of selenium, depending on the chemical form of selenium, the bioavailability of selenium, metabolic processes in the body, biochemical function and toxicity are affected. In natural products, selenium exists mainly in the form of selenomethionine and selenocysteine, and organic selenium has higher body absorption than inorganic selenium. Plants biosynthesize seleniummethionine using selenium absorbed from the soil and store it in proteins. On the other hand, animals cannot biosynthesize methionine, so the selenomethionine introduced into the body through the plant diet is converted from the liver to selenocysteine, and the physiologically active selenium protein is used for synthesis or excreted in vitro. The selenium content in the plant increases in proportion to the selenium content of the soil. Selenomethionine, which is ingested through plant foods, is stored in the body protein as the constituent amino acid of the protein in the body.

Selenium has many effects and is being developed in addition to food and medicine. Especially in Korea, various products are being developed as awareness of the importance of selenium is spreading. For example, in the case of sel-mush, selenium is added to the mushroom medium by adding an amount of inorganic selenium to the mushrooms, and the transferred inorganic selenium is converted to organic selenium in the mushrooms To produce.

On the other hand, selenium may be added to various agricultural products or pharmaceutical products, and Korean Patent Application No. 1996-039331 of Lee Yong-tae discloses a feed composition containing selenium and a method of producing selenium containing livestock using the same. The yeast is cultivated in the added medium and fed to livestock to increase selenium content in livestock products. In this method, the selenium content varies greatly depending on the feed fed with selenium, which is to be included in the livestock food, so it is difficult to supply selenium through the livestock food containing uniformly. Accumulation of milk has a disadvantage of only a very small amount.

Kim Jong-chul's Korean Patent Application No. 1997-018114 discloses a method for providing and edible selenium contained in the embryo powder of Cassia Tora Linna, a natural plant material. There are disadvantages that are difficult to obtain.

Han Kwang-hyun's Korean Patent Application No. 1996-39331 discloses a nutrient solution using selenium dioxide (SeO ₂ ), which has low solubility in water, and then generalizes the beans after three times of 1 hour precipitation and 7 hours incubation. Soybean sprouts are grown for 5 days using the traditional watering method. The method immersed the beans in the selenium nutrient solution for selenium reinforcement and watered the selenium nutrient solution during the cultivation period. However, not only is the process of preparing the selenium dioxide solution complicated, the time and process of soaking soybeans in the solution is long and complicated, but also the selenium nutrient solution is sprinkled for a relatively long growing period of 5 days, but contains a relatively low concentration of selenium. The disadvantage is that it produces bean sprouts. That is, soaking soybeans in 0.01-100 ppm of selenium dioxide nutrient solution and sprinkling the solution during the cultivation period yields bean sprouts having a low selenium content of 0.008-9.1 ppm.

In addition, Kim Hyun Chae Korean Patent Application No. 2003-89903 discloses a hydroponic cultivation method and hydroponic cultivation of selenium using a selenium-reinforced nutrient solution made by dissolving selenium dioxide (SeO ₂ ) in a buttercup culture medium. This method uses a low solubility selenium dioxide in the composition of the nutrient solution, and since the production of the nutrient solution by adding a variety of compounds in addition to selenium, there is a complicated manufacturing process of the nutrient solution.

In addition, no prior patent has been found that combines selenium-containing crops with environmentally friendly organic farming.

Our diet requires not only eating but also the prevention and cure of diseases caused by modern people's stress and various environmental pollution and adult diseases resulting from aging.

As the farmer who produces food for the people, the present inventors enjoy easy and convenient food while producing and distributing environment-friendly safe agricultural products containing selenium that is effective in preventing and healing various diseases and adult diseases. The present invention has been completed through the study.

In addition, the spread of chemical fertilizers and pesticides leads to soil waste and the elimination of microorganisms and earthworms necessary for crops, and eco-friendly farming methods are used to prevent them. In recent years, the country has been exposed to shrinking problems and agricultural products are not safe as food because of residual pesticides. In order to win the competition with cheap foreign agricultural products, such as negotiations with China, it is determined that it is best to produce and distribute environmentally friendly, high-quality, safe agricultural products.

The technical problem to be achieved by the present invention is to provide a method for environmentally cultivating crops rich in selenium.

In order to solve the above technical problem, the present invention

(a) Mix 60 liters of molasses, 60 liters of lactic acid bacteria, yeast, photosynthetic bacteria, actinomycetes and 500 liters of water, and then 500 liters of water. Adding 300 kg of shell powder and 30 kg of sodium selenite, then stirring and uniformly mixing, sealing and aging for 20 days to make selenium-containing environmentally compost;

(e) providing an environment-friendly cultivation method for selenium-containing crops, comprising the step of diluting the amino acid liquor of step (d) to 1,500 cc per ha at 1000: 1 with water.

In the cultivation method according to the present invention as described above, the side fertilization of the step (c) is preferably performed once a month after harvesting 1 month after sowing.

According to the present invention as described above, there is an advantage that can be harvested crops rich in selenium without using chemical fertilizer as a non-pesticide or low pesticide.

Hereinafter, the cultivation method according to the present invention will be described through specific examples. The present invention is not limited to the examples described below.

<Example 1>

Eco-friendly compost manufacturing with selenium

After dissolving 60 liters of molasses in water, dissolve it, mix 60 liters of lactic acid bacteria, yeast, photosynthetic bacteria, and actinomycetes with the released molasses, and add the final content of water to 500 liters of water.

Subsequently, 2,000 kg of rice bran, 200 kg of fish meal, 200 kg of bone meal, 200 kg of castor gourd, 100 kg of charcoal powder, 300 kg of oyster shell powder, and 30 kg of sodium selenite are further added, followed by stirring and mixing. At this time, the content of moisture is suitable so that it does not crumble by grasping the mixed material by hand.

The container with the mixed material is sealed and fermented anaerobicly. After about 7 days of fermentation, white mold is formed on the surface, and microorganisms grow, and after 20 days, it can be used as an environmentally friendly microorganism compost containing serenium.

The use of this compost is good for the growth of useful microorganisms in the soil, improving the physical properties of the soil, promoting the structuring of soil grains, correcting the pH of the soil, enhancing the fertility of the soil, and preventing the pests of the soil, especially the absorption of selenium into crops. This is very useful for increasing the selenium content of harvested crops.

Selenium-containing amino acids Liquid  Produce

Fish is rich in nitrogen, amino acids, which enhance the activity of microorganisms and can be directly absorbed and used by crops.

In the present invention, the preparation of amino acid liquid fertilizer using fish is to contain the microorganism and sodium selenite to promote the absorption of selenium into the crop when side fertilizing.

First, prepare a 600-liter barrel, mix 500 liters of internal organs or by-products, 16 liters of molasses, 8 liters of lactic acid bacteria, yeast, photosynthetic bacteria, actinomycetes, and 16 liters of water, then seal and seal them within 5 to 6 months. Aging completes the preparation of the amino acid liquor that can be used in the present invention.

Eco-friendly composting with selenium

The previously manufactured selenium-containing environmentally compost is evenly sprayed with 3,000 kg based on 1 ha of cultivated soil, and then mixed with cultivated soil of a predetermined depth through a rotary operation.

Garlic sowing

In mid-October, sterilized garlic is sown on cultivated soils that are sprayed with selenium-friendly environmental compost.

Selenium-containing amino acids Liquid  Side fertilization

Beginning in mid-November, when sprouts grow on garlic at sowing, 1500 cc per 1 ha of diluted selenium-containing amino acid solution is diluted 1000: 1 in water and then fertilized sideways.

This side fertilization is applied once a month until the end of June harvest. In other words, side-by-side application is done every December, January, February, March, April, and May.

Comparative Example 1

It is the same as Example 1 except that only selenium is sprayed on the cultivated soil without using selenium-containing eco-friendly compost and amino acid liquid fertilizer, and side-by-side fertilization also differs from using only sodium selenite solution.

Comparative Example 2

In Comparative Example 2, unlike in Comparative Example 1, selenium-containing environmentally friendly compost was sprayed on the cultivated soil, but the selenium-containing amino acid liquid fertilizer was used as a side fertilizer with sodium selenite solution.

Comparative Example 3

In Comparative Example 3, unlike in Comparative Example 1, only selenium-containing environment-friendly compost was used, and only sodium selenite was sprayed on the cultivated soil, but side fertilization was performed using selenium-containing amonoacid liquid fertilizer.

Experimental Example

Garlic harvested in Example 1 and Comparative Examples 1 to 3 was lyophilized and ground to measure selenium content by the ICP-MS method and the results are shown in Table 1.

Selenium content (μg / g dry garlic) Example 1 20.47 Comparative Example 1 6.48 Comparative Example 2 12.13 Comparative Example 3 11.01

As shown in Table 1, the selenium content was the highest in the garlic harvested according to the cultivation method of Example 1. That is, it can be seen that the use of selenium-containing environmentally friendly compost and amino acid liquid fertilizer according to the present invention has an excellent effect of increasing the content of selenium.

This can also be confirmed in that the selenium content is increased in Comparative Examples 2 and 3 than in Comparative Example 1.
