Description

Biodegradable seedling pots {BIODEGRADABLE RAISING SEEDING-POT}

The present invention relates to a biodegradable seedling port, in particular, the thick portion of the pot (back) until the seedlings growing in the port to be transplanted to the growth site by varying the thickness of each seedling port portion to support the pot is not completely decomposed The thin part (thin section) is easy to penetrate as the roots of the seedlings grow, so it is faithful to the function of the biodegradable pots and is suitable for root growth characteristics according to the seedling types, and also simply pots. It is possible to increase the material saving effect than the thick thick pot.

Seedling pots are commonly used to grow seedlings in greenhouses to reduce cold damage and shorten the growth period of crops.

Conventional pots have a bad effect on the soil due to the characteristics of synthetic resins, which are hardly decomposable, and various harmful substances spilled during the decomposition process are molded from a synthetic resin such as polyethylene resin.

Many biodegradable materials have been developed to overcome the problems of such hardly degradable synthetic resin materials, and these biodegradable materials are used in various fields for environmentally friendly and sustainable agriculture.

Prior arts related to biodegradable materials include Korean Patent Publication No. 2000-0057885 (September 25, 2000), "Biodegradable Material Compositions, Biodegradable Material Containers Prepared from the Compositions, and Preparation of the Biodegradable Material Containers. Methods, and many others, and there is a patent application 2002-0059965 (October 01, 2002) "method of manufacturing a biodegradable disposable container" by the applicant of the present invention.

Different kinds of biodegradable materials are used for seedling pots. Unlike the synthetic resin pots, biodegradable seedling pots are planted with seedlings to save work time, prevent root damage, and to temporarily plant plants. Phenomenon prevention can be achieved, and the decomposition of the pot allows the components of the pot to serve as a nutrient source in the process of crop growth.

The problem with the conventional biodegradable seedling pots having a constant thickness was that the seedling pots were decomposed before transplanting the seedlings to the growing place. This is especially due to the effect of 'watering', which is periodically performed for the growth of seedlings, and the binding between the biodegradable material particles is repeated while repeating the process of expanding the volume by drying the pot by the moisture blowing. As it weakens, the decomposition rate is accelerated.

If the seedlings are disassembled before transplanting the seedlings, it is difficult to transport them to the seedlings, and the soil surrounding the roots falls off during the intermediate period or during the seeding process, and the seedling method is lost.

In order to solve this problem, it is possible to develop a special biodegradable material or a strong binder, and to increase the thickness of the biodegradable seedling pot as a whole.

However, one of the focuses of developing biodegradable seedling pots is that they should be competitive with ordinary synthetic resin pots. This, in turn, requires that price increases of biodegradable materials be eliminated as much as possible, so the development and use of specific materials and increasing port thickness may be undesirable in terms of product cost.

Thickening the pot as a whole is also undesirable because the pot has not yet been broken down, which can interfere with the growth of the roots of the plant transplanted into the plant.

However, it is also a cost increase and inefficient to increase the thickness of the pots according to the seedling environment such as seedling time, irrigation recovery and yield for each plant type.

Accordingly, the inventor of the present patent application has devised a means to solve the problem of disassembling the pot before seedlings are transplanted to the growing place while excluding the factor of price increase.

The present invention has been devised to solve the problems of the conventional biodegradable seedling port as described above, the seedling port according to the present invention is a thick portion of the port until the seedlings growing in the port to be transplanted to the growth place by varying the thickness for each part It does not decompose to support the port, and the thin part makes it easier to penetrate as the seedling root grows, thereby solving the problem of 'decomposition before transplanting' or 'non-decomposition after transplant' of a constant thickness To do that,

It aims at promoting seedling growth by adding various nutrients and insecticides to biodegradable materials before pot forming.

In order to achieve the above object, the seedling pot according to the present invention is formed of a biodegradable material, and the rear part (厚 部) that maintains the skeleton without being completely decomposed until the seedling (P) is transplanted to the growing place, As the roots of the seedlings grow, they are decomposed and made of thin parts that are easy to break out of the roots.

Hereinafter, with reference to the accompanying drawings will be described in detail the seedling port of the present invention.

The biggest development of seedling pots according to the present invention is that the seedlings are sown and germinated in the pots before they are grown in the field or rice field, and the pots are decomposed and cannot be transported to the seedlings. In the case of watering or port shifting due to decomposition, the soil in the pot can fall off and provide a structure to prevent the roots from being exposed.

In addition, unlike the conventional synthetic resin port, since the pot of the present invention is planted as it is in the growth area, the root of the plant when transplanted to the growth area should have a structure that easily penetrates through the biodegradable port.

In order to solve this problem, the biodegradable pot according to the present invention is a rear part which maintains the skeleton without being completely decomposed until the seedlings are transplanted into the lobe, and the thin part which is easily decomposed as the roots of the seedlings grow out. consist of.

The meaning of the posterior and the thin part is relative, and the rear part should not be decomposed enough to support the pot, and the thin part is hardly decomposed according to the seeding period such as the seedling period and irrigation volume and recovery according to the type of plant. Should be. The thickness difference between the rear part and the thin part can be adjusted according to the kind of biodegradable material, the kind of binder, and the like.

There may be at least three (eg, 1.0 mm, 1.5 mm, 2.0 mm) portions of the rear and lamella forming portions of the port having such a thickness difference.

For mass productivity, the types of plants can be classified, for example, by dividing the growing period in the greenhouse by 10 days, or by dividing the number of irrigation, intervals and yields during the total growing period by tons. It may be appropriate to produce several types of ports by determining the thickness and formation of the back and thin parts.

In addition, since the biodegradation rate is different depending on the carbon / nitrogen ratio (C / N ratio) of organic materials, the biodegradation rate can be controlled through a suitable compounding rate through material analysis so that the C / N ratio is about 30 to 300. .

The forming part and shape of the rear part and the thin part of the pot may be arbitrarily selected from the inside and / or outside of the pot, but the function of the biodegradable seedling pot may be enhanced by specifying the forming part and the shape.

As shown in Fig. 1 and Fig. 2, the rear portion (TK, thick) of the pot 10 has a plurality of trays (plantlets) until the pot 10 is fully grown and transported to the growing place ( 20) It may be formed in the upper portion of the port, in particular the edge 11 to maintain the skeleton without disassembly in the insertion hole (21). The edge 11 is thicker than the rear part TK of the port outer side surface, and is easily caught by the tray 20 insertion hole 21.

In addition, the thin portion (TN) of the pot 10 may be formed at the bottom portion 13 of the pot for plants (eg, Chinese cabbage) whose roots grow vertically. Reference numeral 13a denotes a drain hole.

On the contrary, for plants (eg, red peppers) that grow with a large amount of roots to the side, the thin portion (TN) of the pot 10 is preferably formed on the lower side of the pot.

In addition, the rear portion TK and the thin portion TN of the port 10 shown in FIGS. 1 and 2 are alternately formed on the outer surface of the port, so that the rim 11 and the rear portion TK of the side surface serve as support skeletons. The bottom part 13 and the side thin part (TN) are almost decomposed at the time of transplanting the seedlings to the growing area, and the roots of the seedlings easily penetrate the thin part (TN) when the pot itself is planted in the growing area such as a field or paddy field. You can grow.

The biodegradable material of the pot is, for example, corn of various cereal hulls such as rice husk and soybean pods, or powder obtained from a powder or beating process of various vegetable fiber materials such as plant stalks such as corn stalks, reeds and crests. It is a mixture of natural binders, such as carbohydrate materials such as flour, flour, rice flour and potato flour, which are kneaded with water and heated and pressed in a mold to form a pot.

In the seedling pot formed with the rear part and thin part as described above, a small amount of nutrients may be mixed with the biodegradable material itself before pot molding, thereby promoting growth of seedlings.

The nutritional component may be a trace inorganic component such as Ca, Mg, Cu, Zn, Fe, Mo. In particular, such inorganic components can be mixed with biodegradable materials in the form of low adsorption force and insoluble form of EDTA and chelate complexes in the soil, thereby preventing soil contamination.

In addition, nutrients may include ammonium phosphate, potassium phosphate and potassium chloride.

It is a kind of chrysanthemum, insecticide substance Chrysanthemum cinerariaefolium (際 蟲 菊) is added in small amounts to prevent the damage of seedlings caused by pests. The pesticidal component of the pesticide country is known as pyrethrin, a yellow oily substance contained in flower seeds. Therefore, the addition of synthesized pyrethrin is also possible. The expression 'parasitic component' in this specification is a concept including such synthetic pyrethrins.

In addition, a small amount of illite powder is further added, and the proliferation suppression of insect repellents and harmful pathogens can be obtained due to unique anion components and the like.

The seedling pot of the present invention can be more easily understood through the following examples.
