Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a seedling capable of achieving a desired growth state and solving environmental pollution problems by adding a secondary material having a utility according to the purpose of growing a seedling, particularly using a non-wood fiber as a main material. It's about pots.
[0002]
[Prior art]
As a conventional nursery pot, a pot formed by molding a synthetic resin sheet such as vinyl chloride into a small flowerpot shape, as is well known, is most often used. Although this seedling pot made of a synthetic resin sheet is inexpensive, it takes time and effort to remove the seedling pot when it is replaced in a field or pot, and when it is replaced, it breaks the soil around the root and damages the root. In addition, there is a drawback in that not only does the growth after main planting be hindered, but also environmental pollution and pollution problems occur when the unnecessary seedling pots are incinerated. In order to solve this drawback, paper-like seedling pots using waste materials generated in the fields of agriculture and forestry instead of synthetic resin sheets have been proposed and used.
[0003]
[Problems to be solved by the invention]
Conventional paper seedling pots made of such raw materials are economical due to the use of waste wood as a feature, and because they are natural materials, they are biodegraded even if left in the soil after use. Despite eliminating the drawbacks of the seedling pots made of synthetic resin sheets, the only expected effects are the aforementioned economic effects and environmental issues, and the pot material and shape affect the growth of plants. The impact is not considered at all, and the requirements for plants, such as the nature of the seedling to be planted, whether it is root vegetable, fruit vegetable, or leafy vegetable, are not considered at all, so it is not expected that seedlings will be sufficiently grown as requested. There was a problem to be solved.
[0004]
Therefore, in the present invention, in order to solve the above problems when raising seedlings of crops that are commonly known as root crops, mass production is carried out using inexpensive plant materials and unused materials, and radish and potatoes are used. The main purpose is to grow the main roots, main stems, tubers, etc., which are important as root vegetables such as burdock, burdock, etc., and the product price is low, tough and safe and harmless. It is an object of the present invention to provide a seedling pot that is biodegraded even when left to stand and does not generate harmful substances even when incinerated.
[0005]
[Means for Solving the Problems]
The means of the present invention taken to achieve the object will be described in terms of common terms with the description of the examples. The seedling pot for root crops of the first invention is composed of bamboo fiber not boiled, Alternatively, a mixed material comprising a boiled fiber material obtained by boiling legumes such as a goat, a carbonized plant material obtained by roasting a non-wood plant material and carbonized, and a small amount of urea is formed.
[0006]
The seedling pot for root crops of the second invention is obtained by roasting a non-boiled bamboo fiber, a boiled fiber material obtained by boiling a legume or legume such as a hedge, and a non-wood plant material. A mixed material comprising carbonized carbonized plant material and a small amount of powder containing urea and silicon dioxide as main components is formed.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
In order to carry out the seedling pot for root crops of the present invention described above, the plant material used is about 7% by weight to 10% by weight of fibers obtained from an antibacterial bamboo stem, stem, skin, core and the like. , About 50% to 60% by weight of reed or goat fiber as boiling fiber material and buckwheat husk, tea husk, oil residue, coffee residue as carbonized plant material (there is no need to bake again because it has already been roasted) A mixture of about 20% to 30% by weight of the carbonized substance obtained by baking (roasting) is mixed with about 15% by weight of urea to obtain a mixed material for molding. The mixed material thus obtained is molded under the conditions of a molding temperature of 180 ° C. or higher, about 200 ° C., a molding pressure of 3 to 6 kg / cm ² , and a molding time of about 24 to 30 sec. In this case, even if a binder corresponding to the sizing agent in paper is not added, the fibers are bound to each other by hydrogen bonding, and a predetermined shape as a pot is maintained. As a means for molding the seedling raising pot, as described above, the bamboo fiber, the boiled fiber material, and the carbonized plant material may be directly pressurized and heated in a mold having a predetermined shape, but these materials are suspended in water. Needless to say, it may be a means of making the slurry turbid to make a slurry, making a paper using a sieving net, and pressing. As described above, the bamboo fiber in the material has antibacterial properties, so that the growth of the side roots of the planted seedlings is suppressed as they approach the side wall of the pot, and the nutrients are accumulated toward the main roots and the main roots grow mainly. It has excellent traits as root vegetables.
[0008]
Also, since it is biodegraded in the soil, it is not necessary to remove it as in the case of a conventional seedling pot of a synthetic resin sheet at the time of replanting. The carbon and urea react to form nitrogen, which acts as a fertilizer.
[0009]
Further, by mixing 2 to 5% by weight of silicon dioxide (= SiO ₂ ), that is, mainly quartz powder, with the above materials, continuous cropping of plants of the same species becomes possible. In general, it has been pointed out that the rot of soil water by Fusarium bacteria is a factor inhibiting continuous cropping, but the mixed silicon dioxide powder causes water in the soil to vibrate to prevent water rot and prevent continuous cropping. Acts to remove the factors that hinder.
[0010]
Like the flowerpot, the molded seedling raising pot is provided with a drainage hole 1 on the bottom surface, a protrusion 3 around the drainage hole 1 to prevent the drainage hole 1 from being closed, and an empty groove 4. Such a nursery pot decomposes in about two months by biodegradation when buried in the soil and left to stand. This period corresponds to a period until the roots of the planted seedlings grow and the seedling pots buried in the soil start to inhibit the growth of the roots of the seedlings. Needless to say, this period varies depending on the plant, but if a small through-hole 2 is formed in the bottom surface or the side wall for the purpose of coping with this, the small through-hole 2 will trigger the biodegradation. . The number of small through-holes 2 is usually one or more and about twelve. Also, if the water-repellent agent is mixed in the above-mentioned mixed material for molding at about 2%, the biodegradation can be delayed for several months. The seedling pot containing the water repellent has a long life in the soil and is useful for bulb cultivation and grafting.
[0011]
The seedling pot for root crops of the present invention has a water adjusting power in a wide range of 7% to 25%, adsorbs water vapor when the humidity in the surrounding air increases, and reduces the adsorbed water vapor when the humidity decreases. It has the function of automatically adjusting to the appropriate humidity by releasing. Therefore, when used as a seedling raising pot, it can withstand temporary drying of the outside air. Furthermore, it is suitable for use in cold regions because it has excellent heat retention (18 ° C. to 10 ° C.) as compared with a pot made of a vinyl sheet.
[0012]
Since raw materials are used and discarded without being used, it is possible to reduce material costs and reduce manufacturing costs. In addition, even when discarded after use, low-temperature incineration is possible, so that the incinerator is not damaged and no dioxin is generated. Furthermore, even when buried in the soil as it is, it is biodegraded by bacteria and enzymes in the soil to produce fertilizer, which contributes to soil improvement and environmental sanitation purification.

[0018]
【The invention's effect】
The seedling pot for root crops referred to in the present invention comprises bamboo fiber, a plant fiber material such as boiled reeds or goats, a carbonized plant material obtained by heat-treating buckwheat hulls or tea husks, and urea. Bamboo fibers in the material have antibacterial properties, so the growth of the side roots of the planted seedlings is suppressed as they approach the side wall of the pot. The nutrients are accumulated in the main roots, grow mainly on the main roots, and have an effect of providing excellent traits as root vegetables.
[0019]
Further, in the embodiment in which the silicon dioxide powder is mixed, there is an effect that water in the soil is caused to vibrate to prevent rot of the water, and a continuous cropping inhibitor is removed to enable continuous cropping of plants of the same species. It also has a wide range of water adjusting power. When the humidity in the surrounding air increases, it adsorbs water vapor to lower the humidity, and when the humidity decreases, releases the adsorbed water vapor to automatically adjust the humidity to an appropriate level. Therefore, when used as a seedling raising pot, there is an effect of enduring temporary drying of the outside air. Also, since it has a heat retaining effect, it is suitable for use in cold regions.
[0020]
In addition, since the main component is made of natural material, even if it is buried in the soil as it is, it is biodegraded by bacteria and enzymes in the soil, so it is not necessary to remove the seedling growing pot at the time of main planting, It also has the effect of saving trouble and preventing root damage due to replanting. In addition, when biodegraded, the carbonized plant material and urea react with each other to produce nitrogen, improve soil as a fertilizer and contribute to the growth of plants, and drill small through holes in the pot wall or use a water repellent Or the like, the period until biodegradation can be adjusted by mixing it, so that it can be applied to a wide range of root vegetables.
[0021]
Since raw materials are used and discarded without being used, it is possible to reduce material costs and reduce manufacturing costs. In addition, even when discarded after use, low-temperature incineration is possible, so that the incinerator is not damaged and no dioxin is generated. Therefore, in combination with the above-mentioned biodegradation action in soil, it has an effect of contributing to purification of environmental hygiene.
