Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a fertilizer, especially a compost,
It belongs to a compost mixed fertilizer containing an aerobic microorganism, an anaerobic microorganism and a fertilizer containing a chelate compound, and a cereal grown by applying the compost mixed fertilizer.

[0002]

2. Description of the Related Art Fertilizer is applied to soil in order to provide nutrients to crops, increase the yield, and prevent the decline of soil strength. The main components of the fertilizer are nitrogen (N), phosphorus (P), and potassium (K), which are necessary for plant growth and especially require large-scale replenishment. Nitrogen promotes plant protein synthesis, cell division and proliferation, root development, leaf stem overgrowth, and promotes nutrient uptake and assimilation. Phosphorus promotes root development, increases the nutrient absorption surface of the root, and activates germination. It also promotes plant maturation and increases grain yield. In addition, it promotes starch production, enzyme and microbial activity, prevents pests and improves the quality of the harvest. Potassium synthesizes carbohydrates and nitrogen compounds, assimilating,
Promotes root development, flowering and fruit set. In addition, water is supplied to adjust the evaporation action. In addition, it increases resistance to cold or pest damage.

As for metals, it is necessary to avoid contamination of heavy metals such as mercury (Hg) and cadmium (Cd) which cause pollution, but some metals are effective as fertilizers. For example, calcium (Ca) exhibits actions such as neutralization of toxic substances, production of chlorophyll, promotion of root growth, and magnesium (Mg) is involved in production of chlorophyll, synthesis of oils and fats, activation of enzymes, and the like. . Also,
Manganese (Mn) promotes respiratory action and oxidase activity, and copper (Cu) is included in oxidase and molybdenum (Mo)
Is included in enzymes involved in the synthesis of vitamin C and fixation of air nitrogen, and iron (Fe) is involved in chlorophyll formation and root protective action.

[0004]

As described above, it is preferable that the metal component functions as an important nutrient for the growth of crops such as cereals and is surely absorbed from the root. But,
Even when metal is mixed with fertilizer such as compost, the metal is often not absorbed by agricultural crops due to decomposition by microorganisms in the compost or reaction with other substances and precipitation as a compound. Therefore, an object of the present invention is to provide a compost-mixed fertilizer that reliably absorbs fertilizing components such as metals into agricultural products. It is another object of the present invention to provide a cereal having good taste and aroma and having an antiseptic and antifungal action.

[0005]

The mixed fertilizer of the present invention comprises 10 to 1000 parts by weight of compost, 0.1 to 10 parts of aerobic microorganisms, 0.05 to 10 parts of anaerobic microorganisms, and
1 to 50 parts of a fertilizer containing a chelate compound. The chelate compound of the chelate compound-containing fertilizer is a very stable complex in which a polydentate ligand having two or more coordination atoms forms a ring with a central metal. When a fertilizer containing a chelate compound is mixed with compost, the chelate compound is not decomposed by microorganisms in the compost or precipitated by a chemical reaction with other substances, and the crop reliably absorbs metal components from the roots in the form of a chelate compound. Since the metal component is not denatured in the compost by microorganisms or the like, the activity of the compost can be further enhanced by adding an aerobic microorganism and an anaerobic microorganism to the compost. This makes it possible to improve the quality of the soil and promote the growth of agricultural crops that absorb nutrients in the soil.

[0006] Chelate compounds absorbed from the roots play important roles in the growth of agricultural crops, such as the production of chlorophyll, the promotion of respiratory and oxidase activities, the synthesis of vitamins, the formation of air-nitrogen fixing enzymes, and the protection of roots in crops. Carry. In addition, it has an antifungal and antiseptic action, maintains the quality of agricultural products for a long time, and improves the taste and aroma of agricultural products.

[0007] Furthermore, when a crop that has been fertilized with a fertilizer containing a chelate compound mixed with compost is ingested into the human body, enzymes such as glutathione S-transferase (GST) molecular species and glutathione peroxidase (GPx) are produced in the body. In addition, detoxification enzymes are produced in the organs in high yield. The enzyme has a detoxifying action, an antioxidant action, and a catalytic action to reduce active oxygen, and converts a reactive electrophilic compound such as active oxygen, aqueous hydrogen peroxide, and organic peroxide into water or alcohols. Since it acts as a catalyst for the reduction reaction, it suppresses the occurrence of mutation, carcinogenesis, cytotoxicity, etc. resulting from the covalent bond of the electrophilic compound to the nucleophilic portion of DNA or protein.

For 10 to 1000 parts of compost on a weight basis,
0.1 to 10 parts of aerobic microorganisms and 0.05 to anaerobic microorganisms
10 parts and 1 to 50 parts of a chelate compound-containing fertilizer are added. If the amount of the aerobic microorganisms is less than 0.1 part and the amount of the anaerobic microorganisms is less than 0.05 part, the amount is not sufficient for the microorganisms to propagate, and the soil cannot be activated. When the amount of the aerobic microorganisms and the anaerobic microorganisms exceeds 10 parts, the content of the microorganisms is large, and fungi that harm agricultural products are generated, which is not preferable. When the amount of the chelate compound-containing fertilizer is less than 1 part, the amount of the chelate compound absorbed into the crop is insufficient, and the effect of improving the taste and aroma of the crop along with the fungicidal and antiseptic effects cannot be obtained. When the amount of the chelate compound-containing fertilizer exceeds 50 parts, the amount of the chelate compound contained in the compost is too large, and unabsorbed metal components remain and accumulate in the soil.

The cereal according to the present invention comprises 10 to 1000 parts by weight of compost, 0.1 to 10 parts of aerobic microorganisms, 0.05 to 10 parts of anaerobic microorganisms, and 1 to 50 parts of a fertilizer containing a chelate compound. And fertilize with a compost mixed fertilizer containing Grains grown with fertilizer mixed with fertilizer
Wheat, rice, soy or buckwheat.
