Description

Liquor composition for cultivating horticultural crops and a method of using the same {LIQUID FERTILIZER COMPOSITION FOR HORTICULTURAL CULTURE AND ITS USING METHOD}

The present invention relates to a liquid fertilizer composition for cultivating horticultural crops, and more particularly, to a functional fertilizer composition for cultivating horticultural crops, which has no risk of environmental pollution, is easy to prepare, and has no risk of misuse of the composition.

More specifically, for cultivating horticultural crops composed of 0.1-2.0 g of boric acid, 0.01-1.0 g of sodium molybdate, 0.1-0.01 g of copper sulfate, and 0.01-0.001 g of surfactant in a 100 g solution containing colloidal Ag 5-400 mg It relates to a liquid fertilizer composition.

Pests on horticultural crops not only harm plants directly or indirectly, but also affect the quality and life of the product after harvest.

Organic synthetic pesticides, which are widely used in Korea, have been continuously used for pest control, and their effects are very effective, and labor and cost can be reduced, but recently, due to the excessive use of organic synthetic pesticides, environmental pollution, ecosystem destruction, crops It is the cause of causing increased resistance to pests. Therefore, the use of such organic synthetic pesticides has been strictly regulated in the developed countries and the number of users is decreasing. Recently, environmentally friendly pesticides have been developed and their use has been increased while using less microorganisms instead of organic synthetic pesticides. Microbial pesticides are known to be naturally friendly and stable compared to organic synthetic pesticides. However, microbial pesticides have been shown to be effective in the laboratory, but the actual packaging has no effect at all, causing problems. In addition, the drug has a low and slow appearance, there is a fixed effect does not appear and the production method is not systematically disadvantageous. Overseas research and use of pesticides using microorganisms began in the 1920s, and more than 70 microbial pesticides have been put to practical use in the United States, Europe, the Netherlands and Japan. In Korea, research for microbial pesticides has been started since 1980, but it is still inadequate compared to developed countries, and most of the basic research and small-scale experimental research have been conducted. Therefore, there is a need for a liquid fertilizer composition that can solve the problems of the aforementioned microbial pesticides and provide a trace element to the horticultural crop.

The present inventors proliferate against microorganisms such as bacteria, spores, bacteria, and viruses that cause plant diseases by treating Ag plants using Ag colloidal solutions as auxiliary additives in the process of researching microbial pesticides to suppress the use of organic synthetic pesticides. It was found that there is an effect to suppress the.

Ag colloidal solution is already available in the market as a health food for human drinking. However, the case of using the Ag colloidal solution in plants has never been in the country, and the practical technology development for the development of the production method of Ag colloidal solution is also insufficient. Unlike conventional organic synthetic pesticides, Ag colloidal solutions are naturally friendly and pollution-free and do not affect the ecosystem.

The present invention is to provide a novel functional liquid fertilizer composition to prevent the infection of various pests and bacteria, spores, bacteria, viruses, etc. that occur during the cultivation of the main horticultural crops, and to promote growth and increase quality and storage after harvest.

Another object of the present invention is the functional liquid fertilizer composition is a liquid

When diluted in horticultural crops and used for foliar spraying and fertilization, it is to provide a method for preventing the disease and at the same time promoting growth and increasing quality and storage after harvest.

The present invention blends 0.1 to 2.0 parts by weight of boric acid, 0.01 to 1.0 parts by weight of sodium molybdate, 0.1 to 0.01 parts by weight of copper sulfate, and 0.01 to 0.001 parts by weight of surfactant to 100 parts by weight of a solution containing 0.005 to 0.4 parts by weight of colloidal Ag. It consists of a liquid fertilizer composition for cultivating horticultural crops.

The present invention also provides a liquid fertilizer for cultivating horticultural crops composed of about 0.04-0.0005% of colloidal Ag, 0.1-0.0% boric acid, 0.01-0.0001% of sodium molybdate, 0.25-0.0005% of copper sulfate and the remainder to obtain the functional liquid fertilizer composition described above. It also relates to the composition.

The composition of the present invention was formulated to be suitable for use in cultivation of horticultural crops, facility cultivation, nutrient solution cultivation, tissue culture and the like. Therefore, the above-mentioned method for growing the horticultural crop also constitutes the present invention. The liquid fertilizer composition according to the present invention has the advantage that, unlike the organic synthetic material, when used in the cultivation method of horticultural crops, there is little soil contamination, and in particular, the salt accumulation obstacle does not appear in the soil where the salt accumulation disorder is severe.

The inorganic substance used in the liquid fertilizer composition of the present invention is colloidal silver (Ag), which uses a nitrogen compound, that is, silver which does not contain nitrogen nitrate at all. As the water-soluble boron source, boric acid, sodium borate, and the like are used. As the water-soluble molybdenum source, sodium molybdate, ammonium molybdate tetrachloride, and the like, copper sulfate, etc. may be used.

In addition to the above-described components, the liquid fertilizer composition of the present invention may be added with trace elements such as iron, zinc, and manganese.

The water-soluble composition which can be distinguished from other liquid ratios can be added to the liquid ratio composition of this invention as needed.

The colloidal Ag (silver) material of the present invention is composed of extremely fine molecules with a diameter of 0.1 to 0.0001 microns.

When the composition of the present invention is treated in a horticultural crop, it is diluted by 100 times to 3,000 fold with water and treated in the basement of the horticultural crop or sprayed onto the ground. In addition, since the liquid ratio of the present invention can be directly supplied by diluting the composition of the present invention to water to be watered when watering, it is possible to reduce the labor by the method of supplying using a watering device.

According to the present invention as a functional liquid fertilizer composition required when cultivating horticultural crops has the following effects.

First, it is possible to prevent the infection of microorganisms such as various pests and bacteria, spores, bacteria and viruses that occur during cultivation of horticultural crops, and also has an inhibitory effect on a wide range of other microorganisms.

Second, it is possible to increase the quality and storage of horticultural crops after their growth and harvest.

Third, it is possible to prevent the physiological disorder caused by the lack of trace elements when planting.

Fourth, it has the effect of increasing the ornamental value by extending the life of flowers after cut flowers.

Hereinafter, the present invention will be described in more detail with reference to the following examples.
