Hereinafter, the present invention will be described in detail.

First, the horticultural clay soil composition for nursery nursery comprising the wood fiber according to the present invention.

The gardening topological composition for gardening for nursery comprising the wood fibers of the present invention,

30 to 55% by weight of peat moss, 30 to 50% by weight of wood fiber, 5 to 10% by weight of pearlite, 3 to 5% by weight of zeolite, 3 to 5% by weight of vermiculite and 0.3 to 0.5% by weight of fertilizer.

The peat moss is widely used as an organic material of soil, and is widely used as an excellent soil improving agent because it is suitable for crop cultivation. It can be mixed with various inorganic materials and organic materials to make various soils suitable for growing various crops. It is good for breeding and potting soils such as vegetable seed sowing, various flower crop sowing and cutting. If the pit moss is less than 30% by weight, there is a problem that the water absorption and nutrient adsorption capacity is reduced, and when it contains more than 55% by weight, growth may be lowered due to excessive humidity.

The tree pulls water from the soil to replenish the water, which can be sustained by the cohesion between water molecules when the water rises due to tension. By the way, the cohesive force of conifers (conduits) does not break the water column better than the hardwoods (conduits), so the conifers have better water absorption capacity than the hardwoods.

In the present invention, the wood fiber (wood fiber) is preferably used conifers, more preferably using pine.

Wood fiber used in synthetic wood is made of wood powder which is pulverized into natural particles.

In gardening topsoil, water retention, breathability, and bobbinding are all things to be checked during crop growing. Lack of any of these can lead to problems with the nursery. When powdered wood powder is used in horticultural soils, it has a good retention and water retention ability, but there is a problem in supplying oxygen in the underground due to poor ventilation. Thus, the problem arises that the roots do not extend and the roots hover.

In the present invention, the wood fiber is preferably cut to a size of 10 to 20 mm in length after a thermo-mechanical process of coniferous wood chips.

When the wood fiber is cut to less than 10mm in length, there is a problem that the air permeability improvement effect of the wood fiber is insignificant, and when cut to more than 20mm in length, the wood fibers are entangled with each other.

The wood fibers have a pH of 5.0 to 7.0 and an electrical conductivity of 1 to 2 ds / m.

The pH of the wood fiber is less than pH 5.0 is not suitable as a horticulture crop medium because the favorite acidity of the horticultural crop is 5.5 ~ 7.0, if more than 7.0, there is a problem that the inorganic salts that the crop can absorb by alkaline alkalinization, electrical conductivity If the electrical conductivity is less than 1 ds / m, there is a problem that fertilizer should be additionally included due to the reduction of the top-bottom fertility, and if it is more than 2 ds / m, there is a problem that may affect the growth of the crop as the salt accumulation soil.

The cation exchange capacity (CEC), which is the size (holding capacity) that the soil can store nutrients, depends on the soil, acidity, or organic content. The higher the organic content, the higher the cation exchange capacity.

Since the wood fibers used in the present invention are mostly organic materials, it is possible to improve the cation exchange capacity (CEC) when the soil is added. In addition, the biggest advantage of the wood fiber is the water absorption capacity (water holding capacity), substantially 1g of wood fiber has the ability to absorb 300g of water. Therefore, when wood fiber is added to the soil, the moisture absorption capacity of the soil is improved, so that the hydrolysis can be controlled, thereby preventing fertilizer leaching due to the hydrolysis and reducing the number of watering, thereby reducing labor. And there is an advantage that the fiber of the wood fiber is present between the pores of the top soil can also be smoothly breathable. This can compensate for the phenomenon that roots are not stretched because oxygen is not supplied smoothly due to the loss of breathability due to over-humidity. In addition, the wood fibers are light, there is an advantage that can reduce the transportation cost.

It is preferable that the wood fiber is included 30 to 50% by weight, the content of less than 30% by weight of the organic matter content is insufficient due to the cation exchange capacity and soil buffering capacity is reduced, if more than 50% by weight so much fiber sowing There is a problem that lumping occurs.

The perlite is a pumice which has a lot of pores by heating the pearlite rapidly, and is a synthetic soil having characteristics of promoting early slidability of crops due to good breathability and water retention. It has no base replacement capacity and has no binding power, but it is used as soil improver to increase soil pore and as a supplementary material for crop or horticultural soil. If the perlite is included less than 5% by weight, there is a problem that the air permeability of the horticultural soil is lowered, if more than 10% by weight may include the fertilizer component is eluted due to the increase in water.

The zeolite (zeolite) is characterized by excellent water retention, bobbin power and drainage power has a high adsorption power of harmful gases and harmful substances, when the zeolite is contained less than 3% by weight, there is a problem that the cation exchange capacity is lowered, including more than 5% by weight If the weight is high, there is a problem that the weight of the horticultural soil is increased.

Vermiculate is a clay mineral made of hydroxide silicate of aluminum, magnesium and iron, and is easily decomposed into acid and has a high cation exchange capacity. It expands when heated. It is porous and has good absorption ability, so it is widely used as heat-resistant material and soundproof material. If the vermiculite is included in less than 3% by weight, there is a problem that the cation exchange capacity is lowered, and when included in more than 5% by weight may cause blowing in horticultural soils.

The fertilizer is preferably contained 0.3 ~ 0.5% by weight, if less than 0.3% by weight is less nutrients of the seedling soil for the growth of crops, there is a problem that the crop growth is poor, if contained in more than 0.5% by weight increase the conductivity (EC) content This can lead to poor germination and crop growth.

100 to 100 parts by weight of the gardening clay composition for gardening dedicated to nurseries containing the wood fibers may further include 5 to 10 parts by weight of oak charcoal, 5 to 10 parts by weight of humic acid extract, 1 to 2 parts by weight and 1 to 2 parts by weight of wood vinegar solution. .

The oak charcoal is produced by heating the oak for 7 days at a temperature of 900 ~ 1,000 ℃, there are a number of micropores to inhibit and neutralize harmful microorganisms and harmful substances, and to improve and promote soil improvement and beneficial microorganisms . If the oak charcoal is included less than 5 parts by weight, the function of the oak charcoal is insignificant, and if it contains more than 10 parts by weight of oak charcoal is an alkaline product, there is a problem of changing the acidity of the topsoil. The oak charcoal is preferably included in a powder state.

The humic acid is a complex organic molecule of organic substances formed in the soil due to natural chemical and biological action, which is an essential organic growth component of the native soil, which is not contained in chemical fertilizer, and is less than 5 parts by weight. When included, the above-mentioned function of the humic acid is insignificant, and when included in an amount of more than 10 parts by weight, decomposition does not occur well, and there is a problem in that it takes a long time to develop an effect.

The yucca extract is a concentrate of the Yukashidigera plant fluid and contains saponin-steroids, sugars, amino acids, and essential minerals as its main components, thereby enhancing crop immunity and controlling nematodes. It acts as a natural nonionic surfactant. Including less than 1 part by weight of the yucca extract lacks the hygroscopicity of the soil, and when contained in more than 2 parts by weight there is a problem that the moisture is excessive during watering.

The wood vinegar has the effect of overcoming crop failure by controlling the supply of trace elements and agricultural nematodes or pathogens in agriculture, and has the function of improving the sugar content of the crop, maintaining freshness, if the wood vinegar is contained less than 1 part by weight If the above function is insignificant, and contains more than 2 parts by weight, the acidity of the soil is temporarily excessively lowered.

The cultivation top soil composition for nursery nursery according to the present invention has the advantages of excellent breathability, cation exchange capacity, organic content, as well as water absorption and water retention, and is easy to manage by increasing the total water retention during horticulture crop growth due to the addition of wood fiber, a new agricultural material Oxygen supply is not smooth due to over-humidity, and there is a merit that compensates for low root extension.

In addition, the present invention is optimally blended organic and inorganic materials, and the reabsorption of water after the temporary drying of the low-breathability of the horticultural clay soil consisting of only organic matter (pit moss) currently used in the nursery using wood fibers and temporary drying of the soil Complementary soil buffering capacity, such as difficult problems. In addition, the addition of functional substances oak charcoal, humic acid, yucca extract, wood vinegar has the advantage of improving the antifungal, antimicrobial, antiseptic effect.

Next, a method for manufacturing a gardening topsoil composition for nursery nurseries comprising wood fibers according to the present invention.

Method for producing a gardening clay composition for nursery nursery comprising the wood fiber of the present invention,

Preparing and cutting wood fibers (step 1);

Steaming the cut wood fibers and pit moss (step 2);

A hot air sterilization step (step 3) of hot steam sterilizing the main material to which perlite, zeolite, vermiculite and fertilizer are added to the steamed wood fibers and pit moss;

Adding a functional material to the main material which has undergone the hot air sterilization step to make a mixture (step 4); And

A normal soil particle size adjusting step of pulverizing the mixture and adjusting the particle size with a selector (step 5);

It includes.

In the step 1, the wood fiber is preferably manufactured by thermo-mechanical process of coniferous wood chips.

The wood fibers have a pH of 5.0 to 7.0 and an electrical conductivity of 1 to 2 ds / m.

It is preferable to cut the prepared wood fiber to a size of 10 ~ 20mm in length. When the wood fiber is cut to less than 10mm in length, there is a problem that the air permeability improvement effect of the wood fiber is insignificant, and when cut to more than 20mm in length, the wood fibers are entangled with each other.

In step 2, the cut wood fibers and pit moss are preferably steamed at a temperature of 80 to 100 ° C. in which organic matters are not destroyed. The steam treatment removes the pollutant of the material itself and prevents the blowing of light wood fibers. In addition, it is possible to increase the hygroscopicity and increase the mixing efficiency by reducing the surface tension, which is an important point in the function of the soil through the steam treatment.

The step 3 is 30 to 50% by weight of the steamed wood fiber, 30 to 55% by weight peat 5 to 10% by weight, zeolite 3 to 5% by weight, vermiculite 3 to 5% by weight and fertilizer 0.3 to 0.5% by weight The mixture is added and mixed, followed by hot air sterilization at a temperature of 60 to 85 ° C. for 3 to 5 minutes.

When the hot air sterilization of the mixed main materials at 60 ~ 85 ℃ for 3 to 5 minutes, when the hot air sterilization temperature is less than 60 ℃, there is a problem that the effect of sterilization, disinfection is lowered, if it is above 85 ℃ There is a problem that denaturation of organic components occurs. At this time, if the hot air sterilization is more than 5 minutes, the absorbency is poor, it is preferable that the hot air sterilization at a temperature of 60 ~ 85 ℃ 3 to 5 minutes.

In step 4, 5 to 10 parts by weight of oak charcoal, 5 to 10 parts by weight of humic acid, 1 to 2 parts by weight of yucca extract and 1 to 2 parts by weight of wood vinegar are added to 100 parts by weight of the main material which has undergone the hot air sterilization. It's a step. The mixture is adjusted to pH 5.5-7.0 so that the soil acidity is close to neutral so that the properties do not change during the seedling period.

In step 5, the mixture is pulverized and screened to adjust the particle size, which allows efficient operation of the work in containers of various specifications for growing the crops, and ensures proper physical properties to effectively vapor, liquid, and solid phase. It maintains and maintains proper elasticity and softens to improve rooting.

The pulverization of the mixture is intended to control the particle size, and does not destroy the basic shape of each material, but only to preserve the specific physical properties in such a way as to break only the particle size dumplings of 10 mm or more generated in the mixture. In addition, the appropriate particle size of the soil is suitable 5 ~ 10㎜ in diameter, which is not less than 80% by weight of the particle size of 5mm or less in the air permeability, drainage is reduced and the rooting is not good, the particle size of 10㎜ or more in diameter This is because the workability of the soil and soil is wasted.

Hereinafter, the configuration and effects of the present invention through the embodiments will be described in more detail. These examples are only for illustrating the present invention, but the scope of the present invention is not limited by these examples.

The wood fibers were cut to a length of 10 mm. The cut wood fibers and pit moss were steamed at 100 ° C. The steamed wood fiber 38% by weight, peat moss 45.5% by weight 9% by weight of pearlite, 3% by weight zeolite, 4% by weight vermiculite and 0.5% by weight fertilizer were mixed with a hot air sterilized for 3 minutes at a temperature of 80 ℃. . The mixture was prepared by mixing 5 parts by weight of oak charcoal powder, 5 parts by weight of humic acid, 1 part by weight of yucca extract and 1 part by weight of wood vinegar to 100 parts by weight of the main material subjected to the hot air sterilization step.
