Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood vinegar liquid hybrid and a method of using the same, and more particularly to a wood vinegar liquid hybrid containing a modified chitosan into which a microbial nutrient is introduced and its use.

2. Description of the Related Art When heating wood in the air, it becomes charcoal if heated in a closed container or a place with little air.
It is well known that a wood vinegar solution can be obtained by cooling the smoke generated during the carbonization process. Wood vinegar has been used as a raw material for methanol in Europe since the 17th century, but the industrial use of wood vinegar has gradually decreased with the development of synthetic chemistry, and is now only used in the agricultural field. . With the recent changes in environmental conditions surrounding agriculture, we have no choice but to tackle the problem of reducing pesticides as much as possible and creating high-quality crops, while soil pests are becoming serious, and the emergence of resistant bacteria and resistant pests. Wood vinegar is gaining attention again for improving the soil environment, increasing the vitality of crops, and improving the effect of pesticides to enhance the vitality of soil and crops. Sterilization of wood vinegar,
The insecticidal and deodorizing effects are well known, but the details of the mechanism are hardly known.
Organic acids such as acetic acid and alcohols, which are the main components, are thermal decomposition components of cellulose and hemicellulose, and phenols are thermal decomposition components of lignin. For example, acid acetic acid alone has a certain bactericidal effect, but even if only acetic acid is diluted and sprayed, it does not have the same effect as wood vinegar, and the effect of wood vinegar containing pyrolyzed components of lignin Differences cannot be explained. The wood vinegar solution is more of a synergistic effect of various components than an effect of a specific component. Also, wood vinegar contains only a small amount of components that are directly absorbed by crops and become nutritious,
It is well known that the use of wood vinegar improves the absorption of fertilizer, promotes the growth of crops, and has a remarkable soil improving effect. The wood vinegar containing various components seems to have a coenzymatic or catalytic function. In this way, the characteristic of the effect of wood vinegar is due to the comprehensive function of the various components contained, and rather than playing a leading role in the bactericidal deodorizing effect and soil improvement effect, the power of the leading role is played. It was a role to raise the arm, and the mechanism of its effect was complicated and could not be explained easily. On the other hand, chitin, as is well known, is widely present in the fields of fungi, plants, and animals.In fungi and plants, it is widely distributed in the cell walls of molds, yeasts, mushrooms, etc., and in animals, it is widely distributed from protozoa, especially crabs. ,
It is famous as a constituent of shrimp cuticle. Chitosan is generally obtained by heating chitin as a raw material in a concentrated alkaline solution to dealkalize it, and C ₃
And 2 hydroxyl groups at the C ₆ position and “a highly reactive amino group at the C ₂ position, they have been chemically modified to produce ethylene glycol chitin, glycol chitosan, etc. It is known that chitosan derivative compounds can be obtained.

DISCLOSURE OF THE INVENTION The present invention aims to strengthen and increase the effects of conventional wood vinegar all at once by combining chitin and chitosan with wood vinegar. By applying the sterilizing power, deodorizing power, and fermenting power of this wood vinegar to the source of the above, the odor generating source itself is converted into a valuable resource.

[Means for Solving the Problems]

The present inventor has paid attention to the relationship between plant chitinase and bactericidal activity in the natural world, and continued research on the antibacterial action and reactivity of chitin and chitosan. As a result, chitosan was chemically analyzed for microbial nutritional components such as amino acids, glucose and nucleic acids. By dissolving the modified chitosan derivative together with chitosan in a wood vinegar solution, we succeeded in obtaining a wood vinegar solution with significantly enhanced bactericidal activity and microbial culturing power compared to conventional products. In various fields such as fertilizers, bactericidal insecticides, deodorants, soil conditioners, the wood vinegar mixed solution of the present invention markedly increases the growth rate of useful microorganisms such as actinomycetes and lactic acid bacteria and grows harmful bacteria such as Escherichia coli in comparison with conventional products. If necessary, it is further mixed with fine particles such as zeolite and charcoal powder,
It is also possible to enhance its efficacy by adsorption and to use it as a granular solid product.

EXAMPLES Examples of the present invention will be shown below.

Example 1 6% of solution A obtained by dissolving and polymerizing chitosan in wood vinegar solution
Chitosan-containing wood vinegar 50%, water 43.6%, DL alanine (Ajinomoto) 2%, glucose (Uehara) 2%, nicotinic acid (organic synthesis) 0.2%, nucleic acid (mutual prosperity) 0.2%, thiaminic acid (Mutual prosperity) The solution obtained by mixing 2% B solution at a ratio of 1: 1 was used as the wood vinegar mixed solution of the present invention.
The diseases of Koroshiba (Onahama Country Club, Fukushima Prefecture) were wilt, rust and baldness, and the amount used was 200 times less than that of 1 l / m ² . The result is 1
After 0 days, the diseases (falling blight, rust, baldness) were almost completely cured, the color of the grass changed from brown to green, and the average leaf length was 1
With a length of ~ 3 m, it grew 5 cm, and there were no side effects of grass after recovery from the disease.

Example 2 An actinomycete growth test was carried out using the same test solution as in Example 1 on granules of 80% chicken manure, 10% charcoal, and 10% zeolite. 80 g of test body impregnated with 20 g of water is a test section [1], 80 g of test body is impregnated with 20 g of commercially available liquid fertilizer, a test section [2], and 80 g of test body is a (chitosan + wood vinegar solution + hormone agent) liquid A test group [3] in which 20 g was impregnated was used, and the test groups 1, 2, and 3 were standardized to have a water content of 20% (weight), and a proliferation test was conducted in a glass beaker at room temperature of 20 ° C. As a result, the proliferation of actinomycetes after 10 days was 50% in test section 3, 20% in test section 2 and 0% in test section 1.

Example 3 Using the same test solution as used in Example 1, a growth degree test was carried out by culturing petite tomatoes. The test solution 1 cc of the present invention was added to the test section [1], the commercial liquid fertilizer 1 cc was added to the test section [2], and the water only test area [3] was used as the test section [3]. 200 twice a month and every other day
Water of cc was irrigated. As a result of sowing on May 1, Test Area 1 was sprouting on May 4 and flowering on June 20 was 5
The height was 0 cm, and on July 10, it was a fruit of 20 mm. On the other hand, the germination of test area 2 is May 4 and flowering 6
23 days (45 cm in height), 1 fruit as of July 10
0 mm, and in test area 3, germination May 5, flowering 6
27th of the month (45 cm). Fruiting as of July 10 is 5 mm
Met.
