Description

ORGANIC BED-SOIL COMPOSITION USEFUL FOR RAISING OF SEEDLING, AND BED-SOIL MAT MADE OF THE COMPOSITION AND PREPARATION METHOD OF THE SAME}

The present invention relates to a composition for hair growth organic top mat, a top mat using the same and a method for producing the same.

Conventionally, the manufacturing method of the top soil for rice seedlings is put into a box-like clay soil or a sheet-like soil material, and then watered, seeded again, covered with seeding, and seeded again. As a result, it was troublesome and labor-intensive during the manufacture of topsoil for hair growth bed.

In order to improve such a problem, various attempts have been made, such as providing a soil composition for hair growth replacing the soil soil, or providing a method of manufacturing a sheet, paper, seedling box, sheet, etc., to which seed is attached. Since the weight of clay soil is close to 5-6kg, including the mother bed, it takes heavy labor for the elderly farmers. Therefore, the idea of the light soil is the horticultural soil (such as peat, peat or coconut shell powder). It is spread as a pouch by adding puffed rice hulls, geolites, perlides, etc., by containing proper moisture like organic compost, but this is merely a substitute for clay soil. It is cumbersome to manufacture, and expensive in terms of price and distribution management burden.

Recently, in Japan, we developed a top soil substitute that is cut by cutting and processing a cheap rice bran, which is half the weight of existing top soil. However, production efficiency of 100 sheets per hour cannot overcome productivity and price competitiveness. have.

In addition, some of the development items claim that the addition of far-infrared ray-producing materials to the topsoil material is an advantage, but this is also a simple topsoil, and the far-infrared effect function of the development purpose is not expected to be remarkable, and it is not related to the purpose of the present invention. It gives meaning.

In addition, Korean Utility Model Publication No. 97-53076 manufactures a topsheet for bedding by spraying water after laying vinyl on the bedding, sowing seeds between thin sheets of paper, and overlapping them. Many, after-care is required, and as a substitute for the topsoil material is very poor sheet formation, practicality is questionable, there is a difficulty in managing the seeding of seeds.

Korean Utility Model Publication No. 98-063774 discloses a nonwoven sheet of a seedling box for transplanting rice seedlings, which reflects a very simple principle to prevent the spread of seedlings to the bottom hole of the bed. Post-processing is inconvenient and there is still a problem to be solved for practical use. In this regard, Utility Model Publication No. 99-33768 recently discloses a seedling box with a built-in nonwoven fabric, but only provides a nonwoven fabric interior for the seedling box.

Recently, a sheet-like soil obtained by compressing and compressing horticultural soil was completely marketed. However, since it is a compression molding, the mat structure is very dense and no pores are formed, so that moisture or air permeability is poor. Inappropriate environment is not suitable for raising and germinating topography of seeds. In addition, the mat structure is weak and easy to break during transportation, and the physical properties and compression system of the horticultural soils is difficult to overproduce and mass production supply in reality.

Therefore, it is easy to germinate and cultivate seeds with excellent air and moisture permeability, and provides a natural organic clay and mat having excellent transport characteristics due to its large burst strength and light weight, and a method of manufacturing a clay mat for raising seedlings having high productivity at low cost. The need to provide is urgent.

In order to solve the above problems, an object of the present invention is to provide an organic clay composition for hair growth using an organic raw material and papermaking fiber, which is a top soil material that seeds can germinate.

Another object of the present invention is to use (i) organic raw materials for soil, which are peat moss, coconut feet, or mixtures thereof, and (ii) papermaking fiber as an active ingredient, and the ratio of organic material and papermaking fiber is 60%. It is to provide an organic topsoil composition for raising seedlings containing from 40 to 90:10.

It is still another object of the present invention to provide an organic soil top mat for seedlings, which is manufactured by vacuum forming the top soil composition for seedlings, having high porosity, high air permeability and moisture absorption rate, and light and high burst strength.

Still another object of the present invention is the first step of preparing a mixed solution by adjusting the pH while adding water and a trace element to the organic raw material and paper fiber, while stirring and dissociating, the mixed solution is deposited in a mat molding tank and the water is vacuum suctioned. By the second step of forming a mat, and to separate the mat from the molding mold to dry to provide a method for producing an organic top soil mat for seedlings.

The present invention relates to an organic clay composition for seedlings using an organic raw material and papermaking fiber, which are seeds of germinating soil, and an organic clay mat using the same, and a method for producing the same.

In one example of the present invention, the present invention relates to an organic clay composition for hair growth comprising an organic raw material and papermaking fiber, which are seeds that can germinate.

The organic raw materials which can be used in the present invention may be peat moss or coconut feet alone or may be used in combination with peat moss and coconut feet, and when the peat moss and coconut feet are used as organic raw materials, these organic raw materials may be used. Considering the properties of Coconut Feet, the content of Pitmoss should not be higher. The main raw materials are obtained by removing impurities from raw materials, adjusting fiber length, thickening, and selecting. For example, pit raw material is mainly used sterilized after washing the middle and high-layer peat in water to remove the ash, dried to sieve, adjust the pH to 6-6.5. Pittmoss gains 1-1.5 mm of organic matter when selected. Pit moss is an organic material with moisture absorption, which improves moisture retention, and has elastic porosity (85% or more), base substitution capacity (CEC) 80-150m.e./100gr, carbon quality (C / N) 15 Since it forms -25%, it physically imparts breathability to the mat and prevents beat due to overdrying, that is, distortion of the mat. There is no secondary fermentation because of the cellulose component, so it has a long lasting effect in preventing depression and maintaining growth, so it is widely used as a horticultural soil or seedling pot material.

In addition, papermaking fibers obtained from corrugated cardboard (carton box), graft paper, or newspaper waste paper are used. For example, impurities obtained by removing impurities such as ink removal and synthetic resin removal, and adjusting the pH are used. Since the graft paper of the papermaking raw material contains carbon ratio, ash, cellulose, lignin and the like, it is preferable to adjust it so that there is no problem in plant growth. The hair growth top mat composition using the conventional peat moss is packaged in a bag in the form of granules and commercially available. However, as a mat composition, the user has to use the mat instead of the top for a mother bed and manufacture a mat. In addition, in the case of manufacturing in a mat form by compression molding, there was a problem that the breakage strength was very low and easily broken, but this problem is solved by adding paper fiber in the present invention. When the pH of paper fiber is adjusted to 6-6.5 on average, it is an organic substance that is similar to the standard of plant growth and decomposes well in the ground, so it is easy to ferment and helps the soil physical properties (soil improvement).

In addition, paper fiber includes graft paper, long fiber material of corrugated paper and shot fiber of newspaper paper, and the tensile and beat phenomena differ depending on the use. Therefore, it is very important to include paper fiber at an appropriate ratio in forming the mating force and mating force with the pit moss. Therefore, in the present invention, the amount of papermaking fiber used for the organic material is preferably 60:40 to 90:10, more preferably 70:30 to 80:20. If the content of paper fiber in the clay composition of the present invention or the clay mat using the same is too high, the rupture strength is so large that beating occurs when overdrying the soil mat in seedlings, which causes difficulty in seed germination and the root of germinated seeds. It causes a break. In addition, if the content of the papermaking fiber is too small, the tear strength is weak, so that the manufactured top mat is easily destroyed, there is a problem that can not be transported and the mattress can not be manufactured due to poor marketability.

In one example of the present invention, the seedling top mat composition may further include the following natural ingredients, for example, may include one or more components selected from the group consisting of chitosan, ocher, and activated carbon. Ocher provides trace elements such as iron, chitosan improves the quality obtained in the case of rice seedlings, and activated carbon has a function of controlling the pH of the soil and a bactericidal action.

In addition, the present invention is vacuum-molded paper fiber for the organic raw material for the soil, high porosity, high breathability and moisture absorption rate is good for germination and growth of seeds, light and bursting organic soil mat, characterized in high strength It is about. The top mat may be prepared using the organic top mat composition.

The seedling top compositions and top mats of the present invention can be used for raising seedlings of all plants, for example, for seedling seedlings such as rice, grass, or reeds. In addition, the organic clay composition of the present invention can be directly used by the user for raising seedlings instead of clay soil, and the mat can be manufactured using only the soil composition not including seeds. It is also possible to prepare the included top mat. In one example of the present invention, in the case of rice seedling top mats, seed mats embedded in mats may be used to cultivate rice seedlings and straight onions so that the seedlings, seedlings, and seedling seedlings are commonly used. Grass can also be used as a light turf shortly after seedling. The shaped mats contain all the nutrients necessary for sterilization and seedling growth, and supplying only moisture and seeds completes the seedling cultivation, and in the case of top mats containing seeds, it is sufficient to supply only moisture.

In one example of the present invention, the burst strength of the topsoil mat prepared from 1.5 to 2% topsoil composition was 3.26-3.64 (kgf / cm ² ) as tested by the KS M 70 17-90 method at the Korea Household Appliance Testing Institute. When the concentration of, the dry burst strength value changes. The dry burst strength is 1 to 5 (kgf / cm ² ) to provide proper transport and germination properties, and is lower when seed is included.

In particular, in the case of soil mats containing seeds, tap water is made of mats and sown to seeds, so that the preparation, selection and sowing process of soil, which requires the most cost and labor for seedling, can be omitted. Not only will it save money and costs, but it will also be beneficial to obtain robust seedlings by improving water and air permeability. In addition, in the case of the direct wave, the seed mat embedded in the seed can be directly planted by itself, so that it is possible to cultivate the wave wave without the purchase of a separate machine or apparatus. Preventing the fall and tangle of coming rice can be harvested smoothly. Therefore, even when injured by natural disasters, the planting lines and abandonment can be separated, so that the harvesting machine can be used, and in the case of rice, pest control and harvesting can be facilitated, and the cost and effort for raising seedlings can be reduced. .

In another example, the present invention is the first step of preparing a mixed solution by adjusting the pH 6.0-6.5 while adding and stirring water to the organic raw material and papermaking fiber, the mixed solution is put into the mat molding machine to deposit the water and vacuum And a second step of forming a solid mat by suction and separating the solid mat from a mat forming machine and drying the mat. In the first step, one or more components selected from the group consisting of trace elements, chitosan, loess, and activated carbon may be included. The method of preparing the organic topography containing seed is similar to that of the organic topography without the seed. There is a difference in that it contains the seeds and maintains the germination properties of the seeds.

Preparing a mixture by adding water to the organic raw material and papermaking fiber for raising seedlings, mixing and adjusting the pH and concentration, and having a grill net embedded in the mold inner surface having a plurality of through holes formed on the body and the bottom. Preparing a molding mold, and depositing the prepared top mat molding mold in a raw material tank in which the prepared raw material and water are mixed so as to adhere the raw material to the grill net by vacuum suction through the grill net of the top mat molding mold. And a mold release mold having a plurality of perforated mat shapes on the body and the bottom thereof, wherein the raw material is attached to the grill net and inserted into the molded mat molding mold by air suction so that the molded mat is separated and fitted into the mold release mold. And, while rotating the demolding mold on the conveyor belt conveyed to the dryer while dropping the molded mat to the conveyor belt It is made to be transported.

Figure 1 shows a process flow diagram and the arrangement of manufacturing equipment for producing a mat of the present invention will be described in detail accordingly.

First, each component shown in the drawings will be described.

The pulper tank 1 is dissoceated so that the weight ratio of raw materials is 2-5% in water, and the material adjustment material is added to the raw material dissociated in water, and reprocessed unresolved fine powder with shear force and impact beating (high and low concentration control). And pH (pH) adjustment, and is a Hopper type storage tank using high density 2-5% pulp for overlaying the top mat for the base plate. The pulp storage tank 3 is a storage tank for transferring low concentration 1% -3% pulp, preferably 1.5-2% forming tank. Pulp molding tank (4) -forming mold (5) is a tank containing a built-in, in the case of a seed-embedded mat, the seed is mixed in a low concentration pulp so that the pulp mixed with the seed is sucked into the molding tank.

Mat molding mold (5) is the seed and pulp mixed in the primary mold (Suction mold) is adsorbed to a thickness of about 1.5-2mm thickness, and then a high concentration of the topsoil composition to 2-3mm thick on the secondary suction (Suction) Do it. The demolding mold 6 is configured to demold the mat in which the demolding mold is formed from the molding mold suctioned up to the secondary, so as to drop lightly onto the conveyor belt for transport. The dryer is dried by low temperature hot air in a conveying apparatus.

Seedling organic materials and papermaking fibers are injected into a Pulper tank (1), and water is supplied from the water tank (2). The organic raw materials and papermaking fibers introduced at this time include water and trace elements, water-soluble binding agent (urea resin), moisturizing agent (CMC), trace elements (Fe. Mg, etc.) and other optional ingredients such as natural disease prevention fungicides. When the solution is added to a concentration of 5% and stirred, the paper is dissociated into cellulose to form a mixed solution. This mixture is mixed with water and the concentration of 1.5 to 2% of the blended raw material is adjusted while supplying water for concentration adjustment.

The mixture obtained in the above step is transferred to a low concentration pulp storage tank (3) to transfer the undissolved fraction to the forming tank (4) while beating and dissociating the microdisintegration with shear force and impact, and the low concentration pulp storage tank. It serves as a storage tank before the transfer to the molding tank and the high concentration pulp storage tank (7) serves to be stored as an overlay material on the molding mat containing the primary seed.

The molding pulp thus mixed and adjusted is dipped into the forming tank 4, and vacuum-inhaled to obtain a shaped top mat.

Figure 2 is a schematic diagram of a device for forming a mat, a hole in which air can flow through the base and the base of the molding mold 5 having a mat shape, the inner surface of the mold has a grill net that can be removed from the raw material pulp Inherent. In addition, it consists of an air suction pipe and an aluminum plate that supports the aluminum mold.

3 is a schematic diagram of a mold release apparatus for detaching a mat formed into a grill net, which is substantially the same as a molding mold, except that the number of holes is small and the grill net is not attached. When the mold release mold 6 is inserted into the molding tank grill net inside FIG. 2 and the mold, a vacuum pump sucks the vacuum, sucks the mat attached to the mold mold grill net at the same time as the desorption and transfers it to the low temperature hot air dryer. Detach and drop on the belt.

The present invention will be described in detail with reference to the following examples, but the following examples are merely illustrative and are not intended to limit the protection scope of the present invention to the following embodiments.

Example

Example 1

A total of 10kg mixed with 8kg of peat moss or cocoapit with pH adjusted to pH 6 and 2Kg of papermaking fiber was stirred and dissociated in a 1-ton capacity pulp tank for 30 minutes, and the concentration was 1.5 to 2%. Prepare the solution.

One set of top mat size (width 580mm, length 280mm, height 7mm) is immersed so that the Suction mold is sufficiently submerged in the molding tank, and the vacuum pressure of the vacuum pump compressed air (7.5bar / m3) is operated for 1 second. After solidifying the solid content of the mold to form a thickness of about 4mm to the entire inner wall of the grill net of the molding mold, the mat attached to the demolding mold is vacuum-adsorbed and dropped to the conveyor conveyer belt. As such, the mat shaped by vacuum molding had 60% moisture but was hot air dried at about 100 ° C.

After drying, 48 sheets of about 2.5% shrink-dried mats were made with an average width of 560mm, length of 265mm, and thickness of 5.5mm, and an average of more than 500 sheets of 2 trillions per hour were produced from the raw materials in the same tank. In addition, the shrink-dried mat was immediately restored to the inner size of the mother box when watered in the mother box and became an organic clay moisturized for germination growth. When entering the production system format, it takes about 12 seconds to complete the molding once, so if the mounting mold is increased, mass production is possible in a short time.

Example 2-6

Experiments were carried out in the same manner as in Example 1 except that the included ingredients and contents in used peat moss or coconut pits and papermaking fibers were the same as shown in Table 1 below. The experimental results are expressed as the strength and porosity of the burst strength.

Organic raw materials Paper Fiber (Kg) Mat characteristics Pit Moss (Kg) Coconut Feet (Kg) Bursting strength Porosity Example 1 80 0 20 fitness fitness Example 2 90 0 10 weakness height Example 3 70 0 30 Strong lowness Example 4 60 0 40 Very strong Very low Example 5 65 15 20 fitness fitness Example 6 65 20 15 weakness height

The burst strength of the mat obtained as a result of preparing the mat as the composition obtained in the above table was classified into three stages of weakness, suitability and strength, and porosity was expressed as low, suitability, and high. In the seedling mat composition, the bursting strength should be suitable and the larger the porosity, the better. Therefore, considering the two factors, the mixing ratio of organic raw material: papermaking fiber raw material is most preferably 80: 20 to 70:30.
