Description

NUTRIENT COMPOSITION FOR FERTIGATION CULTURE OF THE CHIVES AND METHOD CULTURING THE CHIVES USING SOIL CULTURE}

The present invention relates to a fertilizer fertilizer nutrient solution composition for leek, in particular, there is no risk of environmental pollution, easy to prepare and there is no risk of fertilizer misuse nutrient solution for fertilization.

Fertilization is a term that combines watering and fertilization, and fertilization means a cultivation method that manages the amount of water and nutrients to be optimal for growth of leek by simultaneously controlling the water and nutrients supplied to the crop.

Although government cultivation in Korea started about 20 years ago, the distribution rate of 40,000 information of facility cultivation area is currently 7-8. In recent years, however, there has been a sharp increase in interest. Governmental cultivation is suitable for large-scale management, relatively low introductory cost, low cost, viability, improved productivity, good quality uniform production, and is expected to be an environmentally harmonized production system that does not adversely affect the environment. But until now, governmental cultivation has not been used for leek.

Conventional general leek cultivation method has been applied to the soil as a source of inorganic components such as urea, solubilized fertilizer, calorie chloride, high-grade lime and divided into air and fertilizer. This conventional practice is difficult to use because the four fertilizers fertilize the fertilizer and the fertilizer as described above, it is cumbersome to use, and when excessive use of fertilizer occurs salt accumulation obstacle in the soil to produce high quality leek It is a problem and is the main culprit of shortening soil life and causing environmental pollution.

In particular, leek is a health food with abundant nutritional value as well as other edible plants, and is known as a vegetable with various pharmacological effects and is a vegetable that is in constant demand throughout the year. Likewise, fertilizer components are divided between fertilizer and fertilizer, which is a problem in supplying the necessary inorganic ingredients in a timely manner.

Fertilizer cultivation is a fertilizer composition by diluting the fertilizer composition evenly mixed with 10 to 15 kinds of inorganic elements in a suitable amount of water and fertilized in a Venturi method, so the fertilizer method is simple and the fertilizer concentration in the soil can be adjusted to a lower amount than conventional cultivation. There is an advantage in that salt accumulation obstacles are not shown and the use of fertilizers can be reduced, as well as the environmental pollution. In addition, the amount of fertilizer can be reduced to a minimum amount to reduce the production cost.

However, it is difficult to accurately prepare 10 to 15 kinds of fertilizer salts in rural areas, and in reality, some fertilizer salts have chemical reactions with each other to form insoluble compounds. There was a problem in using the direct compounding of the fertilizer salt.

Therefore, there is a need for a fertilizer nutrient nutrient composition for use in fertilization, but until now there is no research on the fertilizer nutrient solution for fertilization in Korea.

The inventors of the present invention invented the nutrient composition for cultivating the rose medium and the cultivation method of the rose medium and the cultivation method and the cultivation method for the cultivation of the lily of the patent application Nos. The present invention was completed by focusing on being able to produce a large amount of leek and preventing salt accumulation of soil.

An object of the present invention is to provide a fertilizer nutrient solution composition that can safely produce a uniform, high-quality, high-yield leek at low cost.

Another object of the present invention is to provide a method for fertilizing the leek using a fertilizer-only fertilizer composition for ease of use and reduced risk of fertilizer misuse.

The above-described object of the present invention is to mix the large elements and trace elements used as the main component of the fertilizer to be suitable for fertilization of leek, but when combined with the components used in the phosphoric acid, magnesium source of the large amount of elements, to produce an insoluble salt, In particular, it is achieved by forming a calcium salt into a two-pack composition which is packaged in a separate package.

According to the present invention, in consideration of the chemical reaction between the fertilizer salts, it is important to formulate in a two-pack type to separate the packaging agent A and agent B. For example, when magnesium sulfate and calcium nitrate having sulfate ions are mixed, calcium sulfate (gypsum) may be formed and the fertilizer line may be closed when fertilized.

The present invention is based on the total weight of nitrogen 15-25, water-soluble phosphoric acid 3-7, water-soluble kali 23-33, water-soluble calcium 18-22, water-soluble magnesium 2-6, weight trace elements 1-2, and water-soluble pigment 0.5-1.5 It consists of a leek tube fertilization nutrient solution composition comprising a weight.

The composition of the present invention consists of a two-pack type which separately packs a substance supplying a water-soluble calcium component and a substance having an anion which reacts with calcium ions to form an insoluble precipitate.

Leek nutrient composition of the present invention was configured to be suitable for use when growing the leek in soil cultivation. Therefore, the method of cultivating the above-mentioned leek nutrient solution composition at the same time fertilization given water and fertilizer at the same time using a simple irrigation system also constitutes the present invention. In the case of using the above watering facilities, the two compositions may be supplied to separate water pipes in order to prevent the closing of the pipeline by insoluble components precipitated by the reaction between the fertilizer components.

As the nitrogen source used in the nutrient solution composition of the present invention, known nitrogen fertilizers in the form of water-soluble nitrates or ammonium salts such as potassium nitrate, calcium nitrate, ammonium nitrate, and ammonium sulfate can be used. It is also used as a source of potassium and calcium. Potassium phosphate, ammonium phosphate, etc. are used as a water-soluble phosphoric acid source, and potassium nitrate, potassium monophosphate, potassium sulfate, potassium chloride, etc. mentioned above are used as a potassium source. The calcium source may be calcium nitrate, calcium chloride, or the like, which is water soluble, but calcium nitrate is preferably used as the nitrogen source. It is also preferable to use magnesium sulfate as the magnesium source used in the nutrient solution composition of the present invention.

Calcium-containing materials, such as calcium nitrate, used in the preparation of the composition of the above-mentioned fertilizer components, can react with some fertilizer salts, for example magnesium sulfate, to produce calcium sulfate, an insoluble calcium salt, thus producing insoluble calcium salts. Packaged separately from ingredients. As such, the composition of the present invention, which is packaged in a two-part form, must be mixed or separately administered just before fertilizing the soil. The above-mentioned calcium nitrate may be packaged alone, but in some cases, it may be packaged together with fertilizer salts containing anions that do not form calcium ions and insoluble calcium salts, for example potassium nitrate.

The two-component composition of the present invention comprises, for example, about 73 potassium nitrate, about 8.3 ammonium phosphate, about 17.9 on magnesium sulfate, about 0.4 on boric acid, and about 0.4 and less than 0.4, and other components such as pigments to form A. Separately packaged with agent B consisting of calcium nitrate. Agents A and B described above are formulated just prior to fertilization at a ratio of about 7: 5 and dissolved in water or separately dissolved in water. For example, A and B agents are dissolved in 1000 liters of water and fertilized at a rate of 700g: 500g, 1400g: 1000g, and 350g: 250g.

When the composition of the present invention is fertilized, 350-1400 g of agent A and 250-1000 g of agent B are dissolved in 1000 liters of water, and the fertilizer is applied to the ground and underground parts of the leek crop.

Trace components used in the nutrient solution composition of the present invention include boron, zinc, copper, molybdenum and the like, which are used in the form of water-soluble salts such as boric acid, zinc sulfate, copper sulfate, and sodium molybdate. You may add a water-soluble pigment | dye to the nutrient solution composition of this invention as needed.

The pigment used in the present invention is water-soluble and does not affect the growth and leaf color of the leek. The above-mentioned pigments may be blended with agent A or with agent B or with both agent A and agent B. However, when blending with both agent A and agent B, it is advisable to mix pigments with different colors. In this way, the use of different color pigments can distinguish between the agent A and the agent B so as not to be confused when using it, and when the nutrient solution is inadvertently used, the container can be broken and flowed out.

The composition of the present invention is used to package the agent A and agent B in a separate package, mixed and used immediately before use, dissolved in 500 to 1000 times of water when used directly supplied to the soil and using a watering device Process by way of fertilization in the basement or ground of leek.

According to the present invention, since the nutrient solution composition is formulated and packaged at a suitable blending ratio for use as a soil cultivating nutrient solution, the blending ratio of each fertilizer component is always kept constant so that cultivation may occur due to overuse or less use of specific components during fertilization. Not only can solve the problem, but also can produce a lot of high quality leek with a constant color and size of the leaves, and can easily supply leek liquor using the irrigation system. In addition, since the calcium component is packaged separately from other components, the calcium component is combined with other components to settle into insoluble calcium salts, thereby changing the balance of other fertilizer components and thus not adversely affecting the growth of leek.

Hereinafter, the fertilization culture leek nutrient solution composition according to the present invention will be described in detail by Examples.
