Cultivation method of functional rice for increasing arginine and glutamic acid and functional rice cultivated and harvested through it

The present invention relates to a method for cultivating functional rice to increase arginine and glutamic acid and to functional rice cultivated and harvested through the same, and more particularly, by spraying animal amino acid fertilizer to grow rice, thereby increasing the arginine and glutamic acid content of rice It relates to a cultivation method of functional rice for increasing arginine and glutamic acid, which can improve taste and sugar content by suppressing protein production while promoting the growth of rice, and functional rice cultivated and harvested through the method.

Rice is a staple food for 2.5 billion people around the world, including Korea, and is the second most produced crop after corn.

This rice refers to polished rice, and rice is divided into brown rice and white rice according to the degree of rice polishing.

Although rice cultivation methods differ somewhat depending on the country or region, rice is cultivated through the process of seed selection, nesting stage, rice planting stage, fertilization stage, pest control stage, and harvesting stage.

In the seed selection stage, good hair grows from heavy seeds, so choose heavy seeds. After selecting the seeds, disinfect the seeds with a seed disinfectant, wash them well in water, and soak them in a bucket of water again to absorb enough moisture.

In the seedling stage, rice seeds are usually sown in a mechanical transplanting nursery box, and seedlings are grown in a warm compromising pond.

In the rice planting stage, most transplants are done by machine, and in the fertilization stage, barn manure and compost are given before spring, and quick-acting base manure, peraphosphate lime, and yuan are given during harrowing. Nitrogen fertilizer is easily lost, so half of the application amount is gibi (base manure) and the other half is usually supplemented twice with tiller and head manure.

In the pest control stage, fungicides are sprayed 2 to 3 times, and insecticides are sprayed about twice when insects occur because the damage is great to snails, black moths, and water weevils.

The harvesting stage is harvested around 40 to 50 days after going out, when most of the rice grains turn yellow and about 3% of the green rice grains remain in the ears.

Climate, soil, and biological environment are important as the rice cultivation environment. Meteorological factors directly affect the growth of rice, such as temperature, solar radiation, and rainfall, and the physical and chemical characteristics of the soil also have a great impact on rice production. . In addition, the biological environment, such as various pests, soil microorganisms and weeds, is also important.

Accordingly, in accordance with the significant economic losses of domestic farmers and related companies, various rice cultivation methods are being developed to differentiate from imported rice and the need for institutionalization for rice consumption measures, Patent Publication No. 10-2019-0128291 (Public date: November 18, 2019), for arsenic-iron oxides of iron oxides combined with arsenic present during the flooding period of rice-growing farmland, reduction of the iron oxide in the farmland There is a method of cultivating rice to suppress arsenic accumulation by adding an oxygen-releasing compound (ORC) to supply oxygen to prevent arsenic-iron oxide from being bonded.

In particular, in recent years, social and economic conditions have changed due to the improvement of income level, and interest in health has increased rather than quantity or food, and the demand for functional varieties has increased.

In addition, due to problems such as water pollution caused by pesticide spraying and food safety, technologies for cultivating rice using eco-friendly fertilizers rather than chemical fertilizers are being developed.

Accordingly, there is a demand for a technical plan for a rice cultivation method capable of improving the rice quality while maintaining or improving the nutritional components of rice.

The present invention has been proposed to solve the above problems, and by spraying animal amino acid fertilizer and cultivating it to be absorbed by rice, it is possible to increase nutrients such as minerals, vitamins, amino acids, etc. of rice, and in particular, arginine, glutamic acid and An object of the present invention is to provide a method for growing functional rice to increase arginine and glutamic acid, which can improve the quality of rice by increasing proline, and functional rice grown and harvested through the method.

In addition, arginine can be increased due to animal amino acid fertilizer to inhibit pathogens in rice, glutamic acid can be increased to improve antibacterial properties and cold resistance of rice, and proline can be increased to alleviate salt damage and activate rice growth. It is an object of the present invention to provide a method for cultivating functional rice to increase arginine and glutamic acid, and functional rice grown and harvested through the method.

In addition, the purpose of providing functional rice cultivation method and harvested functional rice cultivated through the method and glutamic acid to increase arginine and glutamic acid capable of increasing the yield and weight by increasing the yield and weight by increasing the moisture content of the watering season. there is.

In the present invention, functional rice grown and harvested by the above cultivation method.

As described above, according to the present invention, animal amino acid fertilizer is sprayed during rice cultivation to increase minerals such as calcium, vitamin B, and amino acids such as arginine and glutamic acid, which are nutrients of rice, thereby promoting rice growth and protein production. It can improve rice quality by enhancing functionality such as sugar content, coloring, and promotion of hypertrophy by increasing the carbohydrate content of rice, and improving the stickiness of rice by absorbing water as the carbohydrate particles of rice absorb water during cooking. It has the effect of significantly improving the marketability of rice.

In addition, animal amino acid fertilizer increases arginine to inhibit pathogens in rice while increasing glutamic acid to improve antibacterial and cold resistance of rice, thereby improving the control effect of rice, thereby significantly reducing damage to farmhouses, As proline is increased, salinity can be alleviated and the growth of rice can be activated, which has the effect of reducing the labor force of farmers.

In addition, it is possible to increase the moisture content in the watering season and increase the weight of the grain in the ripening period, thereby increasing the yield and weight, thereby improving the income of the farmhouse and improving the economic effect.

In addition, since animal amino acid fertilizer extracted including fish meal and feather meal such as chicken hair having a high amino acid content is sprayed, it is environmentally friendly and has an effect of preventing soil contamination.

1 is a cultivation method of functional rice for increasing arginine and glutamic acid according to an embodiment of the present invention,
Figure 2 is a cultivation method of functional rice for increasing arginine and glutamic acid, including the seedling fertilization process according to an embodiment of the present invention.

Hereinafter, a method of cultivating functional rice for increasing arginine and glutamic acid according to the present invention and functional rice cultivated and harvested through the method will be described in detail with reference to the accompanying drawings.

The present invention can be used for all rice transplant cultivation methods, freshwater direct seedling cultivation methods, and dry direct seedling cultivation methods, but is preferably applied to rice transplant cultivation method, which is a cultivation method in which seedlings are grown to some extent in seedlings and then transplanted to the main field.

In addition, the rice in the present invention is not limited thereto, but may be white rice, black rice, germinated brown rice, red rice, and green rice.

1 is a cultivation method of functional rice for increasing arginine and glutamic acid according to an embodiment of the present invention.

A method for cultivating functional rice for increasing arginine and glutamic acid according to a preferred embodiment of the present invention is prepared by removing rice seeds and salting or repairing them. In other words, the awns attached to the rice seeds are removed, the rice seeds are selected using the specific gravity of salt water, and then washed 2 to 3 times with clear water to prepare.

At this time, the brine may be prepared by dissolving 1.3 kg to 4.2 kg of salt per 20 L of water.

The prepared rice seeds are sterilized by immersing in water contained in a seed sterilizer (S10).

Disinfection of the rice seeds is preferably carried out in the order of hot water disinfection and chemical disinfection.

The hot water disinfection is to soak the rice seeds in water at 50 ° C. to 60 ° C. for 5 to 15 minutes, then take them out and cool them, and more than 90% of the kidney disease can be prevented.

The warm disinfection is difficult to remove germs from rice seeds due to the low temperature when the water temperature is less than 50 ° C or disinfected for less than 5 minutes, and when the water temperature exceeds 60 ° C or disinfects for more than 15 minutes, rice seeds It is ripe and there may be problems that make it difficult to sprout later.

Therefore, the hot water disinfection is most preferably immersed in 60 ℃ water for 10 minutes, then taken out and cooled.

The drug disinfection is performed by diluting the drug and then immersing the rice seeds in the drug solution at 20 ° C to 30 ° C for 24 to 48 hours.

The drug disinfection is difficult to disinfect rice seeds when disinfected at less than 20 ° C or less than 24 hours, and when disinfected at more than 30 ° C or more than 48 hours, the quality of the rice seeds is rather deteriorated due to misuse of the drug There are problems that can be made.

The drug disinfection is preferably disinfected by soaking the rice seeds at 30 ° C. for 48 hours.

At this time, when disinfecting the medicine, the rice seeds are not excessively overlapped, so that the disinfection effect of the rice seeds can be prevented from deteriorating.

After sowing the disinfected rice seeds in seedlings, seedlings are raised for 30 days (S20).

After putting the topsoil in the seedlings and trimming the topsoil to have a uniform thickness, irrigation is performed using a thin-hole watering can before sowing the rice seeds. After that, the rice seeds are well drained and sowed in the nursery. At this time, the rice seeds should be evenly sown in the mother bed.

After watering the seedlings in which the rice seeds were sown, the soil is covered, and the rice seeds are germinated to grow young seedlings.

The raised seedlings are transplanted to the main field (S30).

Rice can be transplanted manually to the main pad or transplanted to the main pad by using a rice transplanter.

After the seedlings are transplanted to the main paddy field, the first fertilization is performed by diluting the animal amino acid fertilizer 200 to 500 times 40 to 20 days before the rice goes out (S40).

The animal amino acid fertilizer may be prepared using chicken hair, shrimp, blue crab, and useful microorganisms as main raw materials.

The chicken hair is composed of keratin as a main component, and amino acids such as cystine, methionine, aspartic acid, threonine, serine, glutamic acid, glycine, alanine, barine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, arginine, proline, etc. contains.

The chicken hair contains more amino acid components than vegetable amino acids or other animal by-products to enhance functionality such as sugar content, coloring, and hypertrophy of rice.

The shrimp and crab are extracted and used as fish meal, and cystine, methionine, aspartic acid, threonine, serine, glutamic acid, glycine, alanine, barine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, proline, tyrosine, tryptophan It is rich in amino acids such as chitosan and taurine.

The shrimp and blue crab contain higher content of arginine and glutamic acid, which can improve the taste of rice, and the like, than chicken hair, and contain a large amount of chitosan, which can help prevent pests and improve rice quality.

The useful microorganism is an abbreviation of useful microorganism group, and is a microbial complex obtained by combining and culturing microorganisms beneficial to humans and the environment using lactic acid bacteria, photosynthetic bacteria, and yeast as main bacteria, and is necessary for fermentation of fertilizer.

The animal amino acid fertilizer may be mixed with the chicken hair and fish meal including the shrimp and crab in a ratio of 3: 5, but is not limited thereto.

Accordingly, the guaranteed components of the animal amino acid fertilizer include nitrogen, potassium, calcium oxide, magnesium oxide, organic matter, 24 amino acids, chitosan, and the like. In particular, the content of arginine, glutamic acid and proline among the amino acids contained in the animal amino acid fertilizer is higher than that of vegetable amino acids or other animal amino acids.

The arginine can inhibit the growth of pathogens in rice and improve the taste of rice by promoting the growth of rice.

The glutamic acid can promote the composition of rice, root and leaf growth, and improve antibacterial properties and cold resistance. In addition, since the glutamic acid promotes the growth of rice, it is possible to increase carbohydrates by suppressing protein production by lowering nitrogen necessary for protein production. Thus, due to the glutamic acid, it is possible to increase the sugar content of rice and improve the taste.

When the proline is supplied to rice, it is accumulated in a large amount in the plant body to prevent plant stress and help overcome salt damage. In addition, the proline can improve the taste, aroma, and sugar content of rice, enhance coloration, and help improve grain enlargement and shelf life.

By using the animal amino acid fertilizer, since the amino acid production process essential for exerting physiological activity in the plant body is omitted, energy consumption can be reduced and the viability ability can be strengthened, and it can be directly used as a necessary function in the plant body without going through the biosynthetic step in the plant body. It is delivered and the effect is fast, and various physiological activities can be strengthened.

The animal amino acid fertilizer should be sprayed 40 to 20 days before the rice goes out. The reason for this is that if the rice is sprayed earlier than 40 days before the rice goes out, it is vulnerable to poor ripening and lodging, and if it is sprayed later than 20 days before the rice goes out, nitrogen content can increase in the ears and grains after the ears go out. This is because there is a problem in that the possibility of occurrence of diseases such as ear blast increases.

In addition, during the 30 days before the rice goes out, it is a young seedling season and tillering, so when the animal amino acid fertilizer is sprayed, the grains may fall off and rather reduce the production of rice.

At this time, when spraying the animal amino acid fertilizer, the animal amino acid fertilizer is diluted 200 to 500 times before use.

When the dilution ratio of the animal amino acid fertilizer is less than 200 times, the concentration is too thick, and the surplus fertilizer component remaining after being absorbed by the roots of rice due to excessive nutrient supply to the rice remains in the soil, lowering the soil temperature. There is a problem of inhibiting the growth of rice, and when the dilution ratio of the animal amino acid fertilizer exceeds 500 times, the concentration is too dilute, making it difficult for rice to absorb arginine, glutamic acid, etc. contained in the animal amino acid fertilizer.

Therefore, it is most preferable to use the animal amino acid fertilizer diluted 250 times.

Here, it is preferable to maintain the temperature of the nutrient solution diluted with the animal amino acid fertilizer at 25 ° C to 30 ° C. If the temperature of the nutrient solution diluted with the animal amino acid fertilizer is lower than 25 ° C, the growth and output of rice may be delayed, and the fruiting may be poor, resulting in a decrease in yield. Temperature of the nutrient solution diluted with the animal amino acid fertilizer When the temperature exceeds 30 ℃, the growth of rice is slowed down, and an environment in which diseases can easily occur is created, which causes a problem in that rice quality may deteriorate.

The diluted animal amino acid fertilizer is applied by foliar spraying.

Since the foliar spraying method is to spray the animal amino acid fertilizer on the crown of rice, the absorption rate is faster than irrigation by giving nutrients or fertilizer to the leaves directly, and the spraying time can be shortened to reduce the labor force of farmers can help

As described above, due to the primary fertilization, arginine and glutamic acid of the animal amino acid fertilizer are absorbed into rice to promote the growth of the rice, thereby suppressing protein production and increasing carbohydrates, thereby increasing the taste and gloss of rice can help to improve beauty quality.

After the first fertilization, the second fertilization is performed by diluting the animal amino acid fertilizer by 200 to 500 times for 30 to 40 days from the date of rice harvest (S50).

When the second fertilization is performed 30 days before the rice planting date, the animal amino acid fertilizer is absorbed for about 10 days, so the animal amino acid fertilizer applied to the rice is not absorbed. It is supplied and not only can adversely affect rice, but also can cause losses such as costs.

In addition, if the second fertilization is carried out after 40 days from the date of the rice, there is a problem in that the harvesting speed may be slowed and the quality of rice may be deteriorated because it may have a great influence on the uniformity, quantity, and quality of rice.

The animal amino acid fertilizer is diluted 200 to 500 times.

When the dilution ratio of the animal amino acid fertilizer is less than 200 times, the concentration becomes thicker and the overall balance is broken, and more nutrients are supplied to the rice than the first fertilization, so the roots of the rice may not be deeply rooted. There are problems that are difficult to prevent damage.

In addition, when the dilution ratio of the animal amino acid fertilizer exceeds 500 times, the concentration becomes dilute, which may cause problems such as nutrient imbalance and reduced absorption of rice, and it is difficult to expect rice growth promotion or there is.

Therefore, in order to increase the number of grains while improving the growth of rice, it is preferable to use the animal amino acid fertilizer diluted 250 times, and the temperature of the nutrient solution diluted with the animal amino acid fertilizer is maintained at 25 ° C to 30 ° C it is desirable

The animal amino acid fertilizer is diluted 250 times and then applied to the foliage.

As described above, when the second fertilization is performed, pest control can be performed simultaneously.

In addition, due to the secondary fertilization, it is possible to reduce the standard labor cost and labor force for control, increase the pollination rate at the exit stage so that flowers can bloom for each tiller branch, and increase the yield by increasing the weight of rice at maturity while allowing more grains to open. be able to

In one embodiment, when disinfecting the rice seeds, the present invention may dilute the animal amino acid fertilizer in the water contained in the seed disinfector and then immerse the rice seeds.

At this time, the animal amino acid fertilizer should be diluted 800 to 1000 times.

When the animal amino acid fertilizer is diluted less than 800 times, the disinfection rate of the rice seeds can be improved to remove pathogens, but there is a problem that resistance can be obtained, and the animal amino acid fertilizer is diluted more than 1000 times. In this case, there is a problem in that the disinfection effect of the rice seeds is reduced and they are easily infected with pathogens.

Therefore, it is preferable to dilute the animal amino acid fertilizer 1000 times to facilitate germination while improving the disinfection effect of the rice seeds.

Figure 2 is a cultivation method of functional rice for increasing arginine and glutamic acid, including the seedling fertilization process according to an embodiment of the present invention.

In one embodiment, the present invention further dilutes the animal amino acid fertilizer by 800 to 1000 times and sprays the foliage after 5 to 10 days from the sowing date in the seedling treatment step of sowing the rice seeds in the seedlings. It can be included (S21).

When the animal amino acid fertilizer is sprayed 5 days before the sowing date of the rice seeds, there is a problem in that gas is generated immediately after fertilization, which can hinder the germination of the rice seeds, and the rice seeds are 10 days from the sowing date In the case of spraying the animal amino acid fertilizer after exceeding the amount, there is a problem in that the amino acid of the animal amino acid cannot be supplied with nutrients before the rice seeds germinate, reducing the fertilization effect.

When the dilution ratio of the animal amino acid fertilizer is less than 800 times, nutrients are supplied in excess of the amount of nutrients that can be absorbed by the rice seeds, which can affect the growth of the rice seeds, and the animal amino acid fertilizer When the dilution ratio exceeds 1000 times, there is a problem in that the effect of amino acids is insignificant because the ingredients such as amino acids supplied to the rice seeds are small.

Therefore, it is preferable to dilute the animal amino acid fertilizer 1000 times and spray the foliage 7 days after the sowing date of the rice seeds.

As described above, by absorbing the animal amino acid fertilizer into the rice seeds sown in the nursery, it is possible to safely and effectively control pests, and there is an effect of helping the growth of rice later.

After the first bedside fertilization step, a second bedside fertilization process of diluting the animal amino acid fertilizer 800 to 1000 times and spraying the foliage 3 to 7 days after the first bedside fertilization step (S22).

When the animal amino acid fertilizer is sprayed 3 days before the first bed fertilization day, there is a problem in that the animal amino acid fertilizer in the first bed fertilization step is not absorbed by the rice seeds and the absorption rate is lowered, and the first bed bed When the animal amino acid fertilizer is sprayed after more than 7 days from the fertilization date, there is a problem that young mothers may be weakened and growth may be damaged.

When the dilution ratio of the animal amino acid fertilizer is less than 800 times, there is a problem that it can cause fertilizer damage by being buried in young hair due to the thick concentration, and when the dilution ratio of the animal amino acid fertilizer exceeds 1000 times, the animal amino acid fertilizer is diluted due to the dilute concentration. There is a problem that the effect of amino acid fertilizer is insignificant.

It is preferable to dilute the animal amino acid fertilizer 1000 times and spray the foliage 12 days after the sowing date of the rice seeds.

After sowing rice seeds in the nursery, by spraying the animal amino acid fertilizer, it is possible to improve the strength to withstand typhoons and the like in the future by making young mothers sleep soundly.

As described above, during rice cultivation, amino acids such as arginine, glutamic acid, and proline contained in the animal amino acid fertilizer can be absorbed into rice to increase the nutritional components of rice, as well as increase carbohydrates due to glutamic acid, thereby increasing the ripening of rice It progresses rapidly and lowers the nitrogen necessary for protein production, thereby inhibiting protein production.

Accordingly, as the protein content of rice decreases, the taste and aroma can be improved to improve the taste quality, and the carbohydrate content increases, so water can be well absorbed during cooking, which has the effect of improving the stickiness of rice. .

In addition, arginine, glutamic acid, etc. of the animal amino acid fertilizer can be absorbed by rice to improve pathogen inhibition, antibacterial properties, and cold resistance, and the effect of storage stability and salt damage can be exhibited through the proline of the animal amino acid fertilizer. Damage and labor can be reduced.

In addition, it is possible to increase the moisture content in the watering season and increase the weight of the grain in the ripening period, thereby increasing the yield and weight, thereby improving the income of the farmhouse and improving the economic effect.
