Abstract

The present invention relates to a seedling farm-dedicated gardening bed soil composition containing wood fiber and a manufacturing method thereof. According to the present invention, the composition comprises: 30-55 wt% of peat-moss; 30 to 50 wt% of wood fiber; 5 to 10 wt% of pearlite; 3 to 5 wt% of zeolite; 3 to 5 wt% of vermiculite; and 0.3 to 0.5 wt% of fertilizer. The composition provides excellent advantages in water adsorption and moisture holding ability while having air permeability, positive ion exchange capacity, and organic matter content. Wood fiber, which is a new agricultural material, is added, total moisture holding ability is increased when seedlings for gardening plants are cultivated, so management is convenient, and poor rooting attributable to insufficient oxygen supply caused by excess moisture is supplemented. Since organic and inorganic materials are optimally mixed, and wood fiber is used, the composition supplements bed soil buffering ability, such as poor ventilation, difficulty in moisture re-adsorption of bed soil after temporary drying, which are disadvantages of gardening bed soil comprising only the organic materials (peat-moss) and currently used in a seedling farm. Moreover, functional materials such as oak charcoal, humic acid, a yucca extract, and pyroligneous liquid are added, antifungal, antibacterial and antiseptic properties are improved.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil-based composition for horticultural use including a wood fiber,

The present invention relates to a soil composition for horticultural use exclusive to a nursery and a method for producing the same, and more particularly to a soil composition for horticultural use exclusive to a nursery school including wood fiber, which is excellent in water permeability, cation exchange capacity and organic matter content, Compositions and methods of making the same.

The conditions for producing good quality seedlings are as follows.

1) It should have ideal physical and chemical properties suitable for growth of crops and soil microorganisms.

2) It should be excellent in water holding capacity, drainage and ventilation.

3) The cation exchange capacity should be high.

Cation exchange capacity is a measure of nutrient storage capacity. As the cation exchange capacity is higher, the fertilizer component such as ammonia nitrogen (NH ₄ ⁺ ) component and the nutrient absorption ability of the nutrient are better, And an environmental atmosphere capable of adsorbing harmful gas and growing vigorously in a pleasant environment with roots can be formed.

4) Organic matter should be aged sufficiently.

Organic matter is not aged sufficiently, and when the decay is severe, the oxygen concentration is lowered to become anaerobic state and the roots are damaged, and a bad odor is generated.

5) Plant growth inhibition substances should not be included.

6) It is light in weight and easy to transport and can be supplied in large quantity.

Since the peat moss soil currently used in the nursery is a soil made of only peat moss raw materials (see Fig. 1), it has a disadvantage in that it lacks soil buffering ability and has low permeability. In order to solve this problem, the nursery field uses a mixture of fertilizer and pearlite itself, which is economically burdened by labor costs and raw material costs.

Korean Patent Laid-Open Publication No. 10-2016-0005898 (2016.01.18.) Discloses a method of producing four kinds of compound fertilizers (hereinafter referred to as " mixed fertilizers ") mixed with an organic material consisting of coco peat and peat moss and an inorganic material composed of pearlite, zeolite, vermiculite, , A yucca extract, a quillaia extract, a seaweed extract, and a microcavity.

The abovementioned horticultural soil has the advantage of enhancing the strength against plants and crops even in a poor environment, but has a disadvantage in that the cation exchange capacity and organic matter content are insufficient.

Korean Patent Registration No. 10-1059847 (Aug. 29, 2011) discloses an agricultural sole soil containing kapok fiber prepared by mixing 99.5-97 wt% of the soils and 0.5-3 wt% of kapok fiber.

Although the agricultural soils containing the carpowing fiber have the advantages of excellent air permeability, cation exchange capacity, and organic matter content, there is a problem that water holding capacity is insufficient.

An object of the present invention is to provide a soil composition for horticultural use exclusive to a nursery school including a wood fiber, which is excellent in not only air permeability, cation exchange capacity, organic matter content but also water absorbency and water holding capacity, and a method for producing the same.

In order to achieve the above object, the present invention provides the following means.

The present invention includes a wood fiber comprising 30 to 55 wt% peatmoss, 30 to 50 wt% of wood fiber, 5 to 10 wt% of pearlite, 3 to 5 wt% of zeolite, 3 to 5 wt% of vermiculite and 0.3 to 0.5 wt% The present invention provides a nursery field soil composition for nursery use only.

5 to 10 parts by weight of oak charcoal, 5 to 10 parts by weight of corn starch, 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 soil composition for gardening exclusive use for nursery field including the wood fiber.

The wood fiber is cut into a size of 10 to 20 mm after thermo-mechanical processing of a coniferous wood chip.

In the step 1, the wood fiber is produced by thermo-mechanical process of a coniferous wood chip, followed by cutting to a size of 10 to 20 mm in length. In step 2, the cut wood fiber and peat moss Is steamed at a temperature of 80 to 100 ° C. In step 3, 30 to 50 wt% of the steam-treated wood fiber, 30 to 55 wt% of peatmoss, 5 to 10 wt% of pearlite, 3 to 5 wt% of zeolite, To 5 wt% and 0.3 to 0.5 wt% of fertilizer are added and mixed, and the mixture is heated at a temperature of 60 to 85 ° C for 3 to 5 minutes.

Hereinafter, the present invention will be described in detail.

First, a soil composition for horticultural use including a wood fiber according to the present invention will be described.

The soil composition for horticultural use exclusive to the nursery of the present invention comprising the wood fiber,

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

The peat moss is widely used as an organic material of the soil and is widely used as an excellent soil improving agent because it is suitable for cultivation of crops. It can be mixed with various inorganic materials and organic materials to make a variety of soil suitable for growing various crops, and it is good for propagation and planting such as vegetable seed sowing, various flower crop sowing and cutting. If the peat moss is contained in an amount of less than 30% by weight, water absorption and nutrient adsorption ability are reduced. If the peat moss is contained in an amount exceeding 55% by weight, the growth may be deteriorated by excessive humidification.

The tree pulls water from the soil to replenish the water. When the water rises by tension, the tree can stand without being broken by the cohesive force between water molecules. However, the cohesiveness is better because the conifer (water pipe) is better than the hardwood (conduit) and the water column does not break, so the conifer has better water absorption capacity than the broadwood.

In the present invention, it is preferable to use coniferous wood as the wood fiber, and it is more preferable to use pine tree.

Wood fiber used for synthetic wood uses wood flour, which is obtained by crushing natural wood into small particles.

Water holding capacity, ventilation and bracing force in horticultural soil are all to be confirmed in the crop raising season. If any one becomes scarce, there will be problems in the slaughterhouse. When powdered wood flour is used in the horticultural soil, the bioresistance and water holding power are improved but the air permeability is poor, which causes a problem in the oxygen supply in the bottom part. So there is a problem that the root can not stretch under the ground.

In the present invention, the wood fiber is preferably cut into a size of 10 to 20 mm after thermo-mechanical processing of a coniferous wood chip.

If the length of the wood fiber is less than 10 mm, it is too short to improve the air permeability characteristic of the wood fiber. If the length exceeds 20 mm, the wood fiber tends to be entangled with each other.

The wood fiber preferably has a pH of 5.0 to 7.0 and an electrical conductivity of 1 to 2 ds / m.

If the pH of the wood fiber is less than 5.0, the acidity of the horticultural crop is in the range of 5.5 to 7.0, which is not suitable as a horticultural crop medium. If the pH is more than 7.0, the inorganic salt that can be absorbed by the crop is limited by the soil alkalization, If the electrical conductivity is less than 1 ds / m, there is a problem that the fertilizer should be additionally included due to the reduced soil bubbling power. If it exceeds 2 ds / m, there is a problem that it may affect the growth of the crop by salt-accumulated soil.

Cation Exchange Capacity (CEC), which is the size of the soil that can store nutrients, is dependent on the soil, acidity, or organic content. The higher the organic content, the better the cation exchange capacity.

Since the wood fiber used in the present invention is mostly organic, the cation exchange capacity (CEC, Cation Exchange Capacity) can be improved when the wood fiber is added to the ground. In addition, the biggest advantage of the wood fiber is the water holding capacity (water holding capacity). In fact, 1 g of wood fiber has the ability to absorb 300 g of water. As a result, when wood fiber is added to the soil, it is possible to control the water content by improving the water absorption ability of the soil, thereby preventing the leaching of the fertilizer due to the singer, and reducing the number of watering and labor. Further, the fiber of the wood fiber exists between the upper and lower voids, so that the fiber can be smoothly ventilated. This can compensate for the fact that the ventilation is destroyed due to the excessive humidification and the oxygen supply is not smooth and the roots can not extend. In addition, the wood fiber is advantageous in that it is light and can reduce transportation costs.

If the amount of the wood fiber is less than 30% by weight, the cation exchange capacity and the soil buffering ability are decreased due to insufficient organic matter content. When the amount exceeds 50% by weight, There is a problem that a time bundle phenomenon occurs.

The perlite is a pumice with abundant pores by rapidly heating the perlite, and is an artificial soil having the characteristics of promoting early planting of the crop due to good air permeability and water retention. It is used as a soil improving agent to increase soil pore and has no bibbing power because it has almost no base substitution capacity. It is used as an auxiliary material for crops or horticultural soil. If the pearlite content is less than 5% by weight, the air permeability of the soil for horticultural use deteriorates. If the pearlite content is more than 10% by weight, the fertilizer component may be leached due to an increase in water drop.

The zeolite is characterized by high water holding power, bending strength and drainage ability and high noxious gas and harmful substance adsorption ability. When the zeolite is contained in an amount of less than 3% by weight, the cation exchange ability is lowered. There is a problem that the weight of the soil for horticultural use is increased.

The vermiculate is a clay mineral composed of a hydroxide silicate of aluminum, magnesium and iron, which is easily decomposed into acid and has high cation exchange capacity. Expands when heated. And is widely used as a heat-resistant material and a soundproofing material because of its excellent absorption ability. If the vermiculite is contained in an amount less than 3% by weight, the cation exchange ability is deteriorated. If the vermiculite is contained in an amount exceeding 5% by weight, flaking in the soil of the horticultural soil may occur.

It is preferable that the above-mentioned fertilizer is contained in an amount of 0.3 to 0.5 wt%. If the amount is less than 0.3 wt%, there is a problem that the nutrient content of the soil for seedling cultivation is small and the growth of the crop is poor. Resulting in poor germination and crop growth.

5 to 10 parts by weight of oak char, 5 to 10 parts by weight of a caustic soda, 1 to 2 parts by weight of an extract of yucca, and 1 to 2 parts by weight of a wood vinegar can be further added to 100 parts by weight of the soil composition for gardening exclusive use for nursery field including the wood fiber .

The oak charcoal is produced by heating oak at a temperature of 900 to 1,000 ° C for 7 days. There are numerous micropores to suppress the harmful microorganisms and harmful substances by adsorption / neutralization, and the soil improvement and beneficial microorganisms are protected and activated . If the amount of the oak char is less than 5 parts by weight, the function of the oak char is small. If the amount of the oak char is more than 10 parts by weight, the oak char is an alkaline product. Preferably, the oak char is contained in a powder state.

The corrosion acid is a complex organic molecule of organic matter formed in the soil due to natural chemical and biological action. It is a natural organic compound which is essential for the growth of the original soil and is not contained in the chemical fertilizer, and less than 5 parts by weight If it is contained, the above function of the corrosion acid is insignificant, and if it exceeds 10 parts by weight, decomposition is not easy and the effect takes a long time to manifest.

The yucca extract is a concentrate of Yucca diegera plant body fluid, and contains saponin-steroids, sugar, amino acid and essential minerals as main components. It strengthens the immunity of crops and controls nematodes. Especially, Which acts as a natural nonionic surfactant. If the yucca extract is contained in an amount of less than 1 part by weight, hygroscopicity of the soil becomes insufficient.

The above-mentioned vinegar has an effect of agronomically controlling the supply of trace elements and controlling the soil nematodes and pathogens, overcoming the obstacle of cropping, improving the sugar content of the crops and maintaining the leading ability. When the vinegar solution contains less than 1 part by weight, The above function is insignificant, and if it exceeds 2 parts by weight, the acidity of the ground is temporarily excessively lowered.

The soil-based composition for horticultural use according to the present invention is advantageous in not only air permeability, cation exchange capacity, organic matter content but also water absorbing ability and water holding ability. The addition of wood fiber as a new agricultural material increases the total water holding capacity of horticultural crops, The oxygen supply is not smooth due to the humidification, which is an advantage of compensating for the phenomenon of low root reach.

In addition, the present invention relates to a method and a device for optimizing the mixing of organic matter and inorganic matter, and the use of wood fiber, which is currently used in nursery sites, and which is composed of only organic matter (peat moss) And the difficult problem. Also, it has the advantage of adding antioxidant, antimicrobial and preservative effect by adding oak charcoal, corrosion acid, yucca extract, and wood vinegar, which are functional materials.

Next, a method for producing a soil composition for horticultural use including a wood fiber according to the present invention will be described.

The method for producing a soil composition for horticultural use exclusive to a nursery of the present invention, which comprises the wood fiber,

Cutting and then cutting the wood fiber (step 1);

Steam processing the cut wood fiber and peat moss (step 2);

A hot air disinfection step (step 3) of hot-air disinfecting the steam-treated wood fiber, peat moss, pearlite, zeolite, vermiculite and fertilizer added main material;

Adding a functional material to the main material after the hot air disinfection step to form a mixture (step 4); And

(Step 5) of grinding the mixture and controlling the particle size of the mixture by selection;

.

In step 1, the wood fiber is preferably produced by thermo-mechanical processing of a coniferous wood chip.

The wood fiber has a pH of 5.0 to 7.0, an electrical conductivity of 1 to 2 ds / m, a moisture content of 18 to 22%, an organic matter of 90 to 95%, a porosity of 85 to 95% (density) of 22 to 31 kg / m < 3 >.

It is preferable to cut the manufactured wood fiber into a size of 10 to 20 mm in length. If the length of the wood fiber is less than 10 mm, it is too short to improve the air permeability characteristic of the wood fiber. If the length exceeds 20 mm, the wood fiber tends to be entangled with each other.

In the step 2, the cut wood fibers and peat moss are preferably steam treated at a temperature of 80 to 100 ° C at which organic matter is not destroyed. By the steam treatment, the pollution source of the material itself is removed and the light wood fiber is prevented from leaking. In addition, the steam treatment can reduce the surface tension, which is an important point of the function of the ground, thereby improving hygroscopicity and increasing the mixing efficiency.

The step 3 may be carried out by adding 30 to 50 wt% of the steam-treated wood fiber, 30 to 55 wt% of peat moss, 5 to 10 wt% of pearlite, 3 to 5 wt% of zeolite, 3 to 5 wt% And the mixture is heated and sterilized at a temperature of 60 to 85 ° C for 3 to 5 minutes.

The mixed main ingredients are hot-air-disinfected at 60 to 85 ° C for 3 to 5 minutes. When the hot-air disinfection temperature is lower than 60 ° C, the sterilizing and disinfecting effects are deteriorated. If the hot- There is a problem that denaturation of an organic component occurs. At this time, when the hot air sterilization is performed for more than 5 minutes, the water absorption becomes poor, so it is preferable that the hot air sterilization is performed at a temperature of 60 to 85 ° C for 3 to 5 minutes.

In step 4, 5 to 10 parts by weight of oak char, 5 to 10 parts by weight of caustic soda, 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 after the hot air disinfection step, It is a step to make. The mixture is adjusted to a pH of 5.5 to 7.0 in order to bring the soil acidity close to neutrality so that properties do not change during the growing season.

In step 5, the mixture is pulverized and sorted to adjust the particle size. In this way, it is possible to efficiently carry out the filling operation in containers of various sizes for cultivating the crops, and ensure proper physical properties, Maintain proper elasticity and smoothness to improve rooting.

The pulverization of the mixture is aimed at the control of the particle size. The pulverization of the mixture does not destroy the basic shape of each material but only the particle size of 10 mm or more generated in the mixture is pulverized to preserve its unique physical properties to the maximum extent. The optimum particle size of the soil is preferably 5 to 10 mm, and if the particle size of the granular material having a diameter of 5 mm or less is 80% by weight or more, the air permeability and drainage are reduced and the rooting is not good. And the waste of the ground is wasted.

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

The pine chips were thermo-mechanically processed to produce wood fibers (see FIG. 2). The wood fibers had a pH of 6.0, an electrical conductivity of 1 ds / m, a water content of 20% Organic matter 95%, porosity 95%, density 25 kg / m3. The wood fiber was cut into a length of 10 mm. The cut wood fibers and peat moss were steamed at 100 ° C. The main ingredients were added with 38% by weight of steam treated wood fiber, 45% by weight of peat moss, 9% by weight of pearlite, 3% by weight of zeolite, 4% by weight of vermiculite and 0.5% by weight of fertilizer at a temperature of 80 ° C for 3 minutes and hot air sterilized . 5 parts by weight of oak charcoal powder, 5 parts by weight of corrosive acid, 1 part by weight of yucca extract and 1 part by weight of wood vinegar were added to 100 parts by weight of the main material after the hot air disinfection step to prepare a mixture. The mixture was pulverized to a particle size of 10 mm and selectively prepared to prepare a soil for horticulture dedicated to nursery.
