Description

Manufacturing method of environmentally friendly plant growth enhancer

The present invention relates to a method for producing a plant growth enhancer mainly composed of a nature-friendly material, more specifically, a chitosan having a deacetylation degree of 70% or more obtained through a chemical or enzymatic method is uniformly dispersed in a distillate and extracted from natural wood. After saccharifying wood vinegar and brown rice flour, it is dissolved in alcohol-fermented brown rice vinegar, and then added with complex amino acid, microbial plant growth promoting bacteria, antagonists and trace water-soluble metals such as boron, copper, iron, manganese, molybdenum and zinc. The present invention relates to a method for producing an environmentally friendly plant growth enhancer which has given resistance to the development and promotion of soil disinfection, soil improvement, soil microbial activation and pest prevention.

In general, due to the industrial wastewater, heavy metal pollution and excessive input of chemical fertilizers and pesticides, the soil gradually loses its buffering capacity, the deterioration of farmland is accelerated, the crop cultivation ability is greatly reduced, and the resistance to pests is weakened. Microorganisms beneficial to plants are gradually losing their activity.

In addition, nitrate is excessively accumulated in crops, and phosphoric acid and girly components are accumulated in soil. Therefore, in order to preserve the soil environment and grow high quality agricultural products, it is urgent to restore the vitality of the soil by fertilization.

In order to improve this point, conventionally, nitrogen, phosphoric acid, girly traces of urea, amino acids, vitamins, etc. have been mixed and used. However, continuous fertilization of chemical fertilizers causes poor crop growth and environment due to salt over-accumulation. There were many problems such as pollution and increased production cost burden.

To improve this problem, chitin and chitosan-based fertilizers containing chitin and chitosan, which are water-soluble ammonium and potassium formate, and trace metals, and weak acid for preventing precipitation of crystals, are disclosed in Korean Patent Publication No. 97-384. Although it has been disclosed, the improvement of soil, the activation of microorganisms are poor, and the environment-friendly crop cultivation is somewhat insufficient. Although chitin and chitosan have excellent properties, there are many problems in plant growth, harvest growth and long-term activation of microorganisms while improving and improving healthy soil.

In addition, it is unable to produce fresh, high-quality agricultural products that are safe and tasty, which consumers want, and environmentally-friendly crops improve soil permeability by improving the air permeability, moisture retention and drainage through the development of environmentally-friendly materials. Various effects are expected such as the growth of microorganisms, prevention of crop disturbances, promotion of crop growth, and yield increase.

Therefore, the present inventors have diligently dispersed chitosan in distilled water as a result of earnestly researching in order to prepare an environmentally friendly plant growth enhancer whose main component is chitosan having a deacetylation degree of 70% or more obtained through chemical or enzymatic methods. After dissolving the wood vinegar and brown rice extracted from natural wood with alcohol fermented brown rice vinegar, 17 kinds of complex amino acid, plant growth promoting bacteria, antagonistic bacteria and a small amount of water-soluble metals were added and stirred to promote plant development, soil disinfection, soil improvement, The present invention has been completed successfully by obtaining an environmentally friendly plant growth enhancer that provides soil microbial activation and resistance to pest prevention.

In the present invention, the growth enhancer is thermally decomposed by heating natural wood with chitosan, a natural polymer material having a deacetylation degree of 70% or more obtained through chemical or enzymatic method, in a distillate at 0.05 to 10.0 g / l and maintaining 15 to 40 ° C. After cooling, the extracted wood vinegar and brown rice powder were saccharified, and alcohol fermented brown rice vinegar was diluted 1: 1 by weight ratio, and 50 ~ 200g / ℓ was gradually added to completely dissolve the chitosan powder particles. 17 amino acids 50 ~ 200g / ℓ, 0.5 ~ 1.0 g / ℓ of plant growth fungi and antagonists in each order and mixed evenly and boron 3.0 ~ 5.0 g / ℓ, a water-soluble metal component which is an essential element of crop growth, 3.0 to 5.0 g / l of copper, 7.0 to 10.0 g / l of iron, 7.0 to 10.0 g / l of manganese, 0.8 to 1.0 g / l of molybdenum, and 3.0 to 5.0 g / l of zinc are added and then dissolved by stirring.

In addition, if the deacetylation degree of chitosan is 70% or less, the dissolution time is long and the initial stage has little viscosity because chitosan is dispersed in distillate, but the viscosity increases rapidly from the dissolution of chitosan, increasing the temperature and increasing the temperature of wood vinegar and brown rice. Slowly add vinegar.

The pH of chitosan in dissolved state is 3.0 to 3.5, which temporarily stops the activity of microorganisms and then acts upon dilution of water with plants and soil.

In addition, the wood vinegar extracted by heating and pyrolyzing oak, which is a natural wood, is reddish brown or black brown transparent liquid, specific gravity 1.02∼1.04, pH 2.3∼3.5, sugar content 6.5∼12, acetic acid content of 60% or higher and fermentation of brown rice The aged and filtered brown rice vinegar contains 80 g of brown rice per liter, and the acidity is 6.0 to 7.0%.

Crops combine the inorganic nitrogen absorbed from the soil and organic matter derived from carbohydrates, which are photosynthetic products, to be amino acids and nitrogen-containing organic compounds, and various types of amino acids combine to form proteins. Histidine, which plays an important role in the process, arginine, which gives a pleasant taste, serine, and glutamic acid, which combines with kali salts to enhance bacterial resistance, methionine to promote fruit growth, tryptophan, which enhances color and gloss, and catalyzes the synthesis of amino acids. Numerous microorganisms survive around aspartic acid, such as threonine, glycine, alanine, cystine, valine, isoleucine, leucine, phenylalanine, lysine, aspartic acid and capillary roots. And directly or indirectly at the root of the plant It is absorbed by and promotes healthy growth. In addition, as a plant growth promoting agent, it is used as a combination of Suthermomas fluorescein, tricodema bead and food, and bacillus subtilis as an antagonistic bacterium that functions to sterilize or inhibit pathogens by production and parasitics. By using microorganisms containing nematode antagonists of Tricorda polyspora, Dactylella shionapagaas robotris docchi riders, it suppresses the occurrence of diseases by nutrient supply function, growth promoting function and beneficial antagonistic growth of plants. Soil pores are formed by decomposition products and hyphae caused by soil microorganisms, which facilitates air communication and permeability, and increases water retention, which promotes extension of crop roots.

The input amount of boron, copper, iron, manganese and molybdenum zinc, which are water-soluble metals, which are essential elements of crops, are added with the minimum amount by the Fertilizer Management Act (No. 96-96) in order to prevent excessive accumulation of plants and soil. do.

In accordance with the present invention, the environmentally friendly plant growth enhancer is preferably diluted evenly with water at an appropriate concentration according to the growth state of the crop, and evenly sprayed on the leaves of the crop.
