Abstract

The present invention relates to an artificial soil deodorant and composition for plant cultivation that facilitates plant growth of excellent lightweight aerated concrete that can hold soil microorganisms that are lightweight and have characteristics of organic and inorganic complex fertilizers.

Conventional artificial soils use organic materials chemically prepared as a binder. These organic materials have a low biodegradability, which may adversely affect the soil and have a low bobbin power.

Therefore, in the present invention, 20 parts by weight of cement, 20 parts by weight of quicklime, 50% by weight of siliceous material, and 10 parts by weight of gypsum were mixed and 5 to 35 parts by weight of yellow soil was added to the siliceous material.

After adding water to these mixtures to make a slurry and then precuring at a temperature of 90 ℃, the cured body is cut to size and treated for 8 hours under saturated water vapor pressure of 10 atm to produce ocher lightweight foam concrete, and The process of pulverizing ocher lightweight aerated concrete to a size of 5 to 10 mm using a pulverizer, mixing the pulverized product with pig manure in a volume ratio of 1 to 1, and then fermenting aerobic conditions in a fermenter;

During fermentation, the initial temperature was maintained at 35 degrees Celsius. When the fermentation temperature was increased to 35 degrees Celsius, it was assumed to be ripe and finished. It is to manufacture artificial soils for plant soils that can hold beneficial microorganisms.

Description

Artificial soil deodorant and composition for plant cultivation

The present invention relates to an artificial soil deodorant and composition for plant cultivation that facilitates plant growth of excellent lightweight aerated concrete that can hold soil microorganisms that are lightweight and have characteristics of organic and inorganic complex fertilizers.

The artificial soil should have light weight, breathability, and boilability. Such conventional methods include a composite agent (patent publication No. 93-11798) prepared by mixing acrylic acid with water and a binder in which composite fertilizer is dissolved in expanded perlite. ,

Artificial soil jelly (Patent Publication No. 96-40135) prepared by adding a pigment and a fertilizer component to an amide compound,

Food fermentation compost, briquettes, etc. are mixed with light aggregates (Perlite, Verniculite), and then sprayed (patent publication No. 95-2569) has been proposed.

However, the conventional method described above uses an organic material chemically prepared as a binder, which has a disadvantage of low biodegradability, which may adversely affect the soil and have a low binding force.

In addition, the composite agent prepared by mixing acrylic acid with water and a binder (Patent Publication No. 95-2569) has a disadvantage in that it can be molded by adding food fermentation compost which is an organic fertilizer.

The present invention is to produce artificial soil for plant cultivation that is lightweight and has the efficacy of organic, inorganic compound fertilizer and moisturizing and can immobilize soil microorganisms.

The present invention is intended to be used directly for plant cultivation, especially hydroponic cultivation as artificial soil prepared by crushing the ocher lightweight foam concrete to 5 to 10 mm and compost.

In the present invention, when used as vegetation soil in civil engineering, landscaping, etc., finely crushed to 1 to 2 mm and then mixed with yellow soil, and used to form spherical and plate shapes using an inorganic binder as a binder.

The present invention is to be used as a deodorant for a variety of uses because the prepared ocher lightweight concrete is excellent in porosity and adsorptivity and effective in removing odors.

The present invention relates to lightweight foamed concrete that has already been recognized for its efficacy as a siliceous fertilizer.

Lightweight foam concrete is made by slurrying siliceous raw materials, cement, limestone, and gypsum into slurry, mixed with small amount of aluminum paste as foaming agent, and then pre-cured at a temperature of 40 to 90 ℃, and the cured body is cut to size 10 to 12 It is prepared by curing for about 7 to 14 hours under saturated steam at atmospheric pressure.

The lightweight foamed concrete thus prepared is mixed with large pores of 0.5 to 1.5 mm formed by hydrogen gas and micropores formed by crystal growth.

In the present invention, in the manufacture of lightweight foam concrete, the addition of ocher having the ability to immobilize the soil microorganisms.

Lightweight foamed concrete is generally 10-30% by weight of cement, 10-20% by weight of quicklime, 40-75% by weight of siliceous raw materials, and 2 to 10% by weight of gypsum.

In the present invention is prepared by adding 5 to 35 parts by weight of ocher relative to the siliceous raw material in the raw material.

When the yellow soil is added in less than 5 parts by weight based on the siliceous material, the characteristics of the yellow soil do not appear in the prepared lightweight foam concrete.

It can be determined that ocher is not detected by X-ray diffraction analysis.

In addition, when added in excess of 35 parts by weight, the porous structure which is the structure of lightweight foamed concrete is lost.

The prepared ocher light weight aerated concrete is crushed to a desired size.

The crushed product prepared for imparting a bobbin force to the crushed ocher lightweight foam concrete was composted using the moisture control material.

Composting is mixed with organic matter such as livestock manure, livestock slaughter, blood, etc. in a volume ratio of 1 to 1 and fermented in a fermenter to fully mature.

After that, the screen was filtered to remove artificial compost that was not attached to the crushed yellow light-foamed concrete.

The manufactured artificial soil has moisturizing power, bobbing power, and breathability, and its volume specific gravity is about 0.5.

In addition to the organic fertilizer effect has a siliceous fertilizer effect is advantageous for plant cultivation.
