Description

  The present invention relates to an improving agent for planting soil and a method for improving planting soil used for growing growing plants such as radish, carrot, potato, tomato, Chinese cabbage, flowers and fruit trees.

  Microorganisms related to plant growth such as filamentous fungi, actinomycetes, and bacteria live in the growing soil, and are in a food chain with filamentous fungi → actinomycetes → bacteria. There are gram-positive and gram-negative bacteria in all of the filamentous fungi, actinomycetes, and bacteria. These gram-negative bacteria are bad for plant growth, and most plant soil disease bacteria are gram-negative bacteria. Even such bad bacteria may fix weeds, so weeds are not a problem. On the other hand, microorganisms such as bacteria that suppress gram-negative bacteria to prevent plant disease infection and fix nitrogen as fertilizer live. However, the sterilizing agent used in the conventional soil treatment has a weak sterilizing power and cannot sufficiently remove harmful bacteria. On the other hand, a powerful sterilizing agent removes even effective bacteria for cultivation. These strong and conventional various disinfectants have a strong irritating odor and are harmful to human livestock.

  Therefore, a method of activating soil for planting by spreading an aqueous solution of chlorine dioxide having a concentration of 500 to 700 ppm on the soil at a rate of 2000 to 2500 L per reaction and selectively sterilizing microorganisms in the soil is proposed. (For example, refer to Patent Document 1).

  However, in the above activation method, the residual rate of filamentous fungi harmful to planting is remarkably reduced to 0.06%, but the residual rate of bacteria effective for planting is very small, 0.177%, In addition, the survival rate of actinomycetes was reduced by almost half to 0,558%, and there was a problem of sterilizing a large amount of bacteria effective for planting.

Japanese Patent Laid-Open No. 7-17931 (Japanese Patent No. 2686591)

  The present invention has been made in view of the above-mentioned conventional problems, and sufficient and effective bacteria for plant cultivation are left in the soil, and harmful bacteria are actively removed to activate the soil. It aims at providing the improving agent of the soil for planting which is harmless to human livestock, and the improvement method of the soil for planting.

  In order to solve the above problem, the plant soil improving agent according to claim 1 of the present invention has a particle size of 0.3 μm to 0 μm with respect to 1,000 cc of an aqueous sodium chlorite solution having a concentration of about 100,000 ppm. 0.03 μm green silicon carbide is mixed in a proportion of 0.1 g to 0.01 g.

In the present invention, sodium chlorite easily dissolves in water, and when used, it is diluted to an appropriate concentration and distributed in soil, so that effective bacteria such as bacteria remain, and gram negative Fungi harmful to planting can be destroyed or significantly reduced. That is, chlorine dioxide gas ClO ₂ O ₂ (active oxygen) generated from sodium chlorite sterilizes harmful bacteria such as Gram-negative bacteria. In addition, chlorine dioxide gas produced from sodium chlorite is a gas body with a specific gravity of 1.1 and heavier than water, so it goes down naturally in the soil, so green silicon carbide is used for various fungi of phytopathogenic microorganisms. It is possible to promptly deliver chlorine dioxide produced from sodium chlorite into the cells and improve the sterilization power. In addition, the green silicon carbide remaining in the soil is effective in delivering nutrients (nitrogen, phosphoric acid, potassium), etc. to the planted plant, reducing the amount of fertilizer and improving the plant vigor. It becomes difficult to be attacked by pests. The particle size of the above-mentioned green silicon carbide was set to 0.3 μm to 0.03 μm in consideration of the kind of bacteria and the effect of delivering nutrients to the plant planted with green silicon carbide remaining in the soil. In addition, when 1,000 cc of an aqueous solution of sodium chlorite having a concentration of about 100,000 ppm is mixed with 0.1 g to 0.01 g of green silicon carbide, it is diluted to 1,000 ppm for use. In this case, the amount of green silicon carbide dispersed in the aqueous solution becomes 0.01 g to 0.001 g, so that the above effect can be obtained effectively.

  A planting soil improving agent according to claim 2 of the present invention is characterized in that, in claim 1, the improving agent is diluted with water to a sodium chlorite aqueous solution having a concentration of about 1,000 ppm. To do.

  In the present invention, sodium chlorite is easily dissolved in water, an aqueous solution of sodium chlorite can be easily diluted to a uniform concentration, and can be easily penetrated into the soil simply by spreading.

  The improvement method of the soil for planting which concerns on Claim 3 of this invention is a green silicon carbide with a particle size of 0.3 micrometer-0.03 millimicrons with respect to 1,000 cc of sodium chlorite aqueous solution with a density | concentration of about 100,000 ppm. An aqueous solution obtained by mixing at a rate of 1 g to 0.01 g is diluted with water to make an aqueous solution of sodium chlorite having a concentration of about 1,000 ppm, and this diluted solution is about 2,000 to 2, After spreading at a rate of 500 L, it is left for about 5 days to 2 weeks until chlorine dioxide gas almost disappears, and after drying the soil, fertilizing and cultivating the plant is characterized.

  In the present invention, the generation of effective bacteria such as bacteria can be achieved by spreading a dilute solution of a sodium chlorite aqueous solution containing green silicon carbide at a rate of about 2,000 to 2,500 L per 10 ares of soil. Can be generated efficiently. As a result of repeated experiments of various ratios per 10 ares of soil, the ratio of about 2,000 to 2,500 L was found to be the range where the ratio of this category is most excellent for the generation of the effective bacteria. It is.

  Moreover, chlorine dioxide gas is almost lost by leaving the diluted solution of sodium chlorite containing green silicon carbide on the soil and leaving it for about 5 days to 2 weeks. Then, after drying the soil, fertilizing, growing the plant, leaving it for a while, and investigating the number of microorganisms after drying, the presence of effective bacteria such as bacteria and actinomycetes necessary and indispensable for plant growth As a result, it was found that the harmful details were almost destroyed.

  Green silicon carbide has less impurities than black silicon carbide, and is mainly composed of carbon such as petroleum coke and silica, silica and carbonaceous material are placed between the electrodes, the electrodes are connected by a graphite powder core, and the raw material is covered. After that, it is manufactured by the Atchison furnace method in which electricity is applied and heated, the silicon carbon direct reaction method, or the like. Further, as described in Japanese Patent Application Laid-Open No. 2003-176119, green silicon carbide is a high-frequency electromagnetic wave of 2 GHz or higher using silicon-integrated biomass carbide such as rice husk carbide or a mixture of carbon powder and silica powder as a raw material. Can be manufactured by irradiation.

  According to the present invention, by spreading an aqueous solution of sodium chlorite containing green silicon carbide on the soil, bacteria and the like effective for plant cultivation remain in the soil in a relatively large amount and are harmful to plant cultivation. It is possible to improve the soil by destroying or remarkably reducing gram-negative bacteria and the like, thereby producing an effect that can provide extremely effective results for crop cultivation. In addition, green silicon carbide can provide an effect of improving the sterilizing power by quickly delivering chlorine dioxide produced from sodium chlorite to various fungi of phytopathogenic microorganisms. In addition, the green silicon carbide remaining in the soil is effective in delivering nutrients (nitrogen, phosphoric acid, potassium), etc. to the planted plant, reducing the amount of fertilizer and improving the plant vigor. The effect of making it difficult to be attacked by pests can be achieved.

  In addition, sodium chlorite is very soluble in water, and can easily disperse and disinfect into the soil by simply spreading it. In addition, it is an aqueous solution, so it works safely without generating harmful gases. In addition, since it is an aqueous solution, it has excellent effects such as easy and accurate adjustment of its concentration.

  Furthermore, various pathogens adhere to stems and leaves during plant growth, and diseases occur. When sodium chlorite is diluted to a concentration of 10 ppm to 500 ppm corresponding to the disease, It is effective in removing and preventing disease.

  When cultivating plants, sodium chlorite aims to activate soil by actively removing harmful bacteria that are harmless to human livestock, leaving necessary and effective bacteria in the soil. This was realized by mixing green silicon carbide into the aqueous solution.

  First, an aqueous solution of sodium chlorite having a concentration of about 100,000 ppm is prepared, and 2 g to 0.2 g of green silicon carbide having a particle size of 0.3 μm to 0.03 μm is mixed in 20 L, and then diluted with about 2,000 L of water. An aqueous solution of sodium chlorite having a concentration of about 1,000 ppm was made.

  When this diluted solution was spread at a rate of about 2,000 to 2,500 L per 10 ares of soil and allowed to stand for about 1 week, the chlorine dioxide gas almost disappeared. Next, the soil was dried and then fertilized, and left to stand for 4 to 5 days, and then tomato seedlings were planted. After that, as a result of investigating the number of microorganisms in the soil after drying, it was confirmed that the harmful bacteria such as Gram-negative bacteria were significantly reduced and the soil was sufficiently improved.

It can be used not only for edible plants but also for ornamental plants, flowering plants and flowering plants.
