DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a soil disintegrable rubber composition suitable for use as a potting material for sticking to soil attached to plant transplant roots, and a root for plant transplants produced using the same. Rubber band, rubber tape,
The present invention relates to a rubber net and a binding cloth.

[0002]

2. Description of the Related Art In transplanting, if the roots are exposed to the sun or wind, the root viability of the roots is reduced. In general, the potted soil that adheres to the roots at the time of excavation is held and transported as it is, and excavated at a predetermined place. It is buried in the hole as it is, but in order to improve the efficiency of holding potted soil that adheres to the root during transportation, in Japan, seedlings such as boxwood, satsuki, etc., attach to the root with straw, linen or rice paddy, with straw. The pots are wrapped and tied with a fly. By the way, the pot value of the seedlings is zero because the pot soil that adheres to the roots during transportation is poorly retained and the roots that have adhered to the roots are dislodged and the roots do not take root after transplanting. However, due to lack of binding workability, a method has been proposed in which a rubber band is used instead of a fly to bind linen, straw or straw. By the way, stretch the rubber band and linen or komoko,
The ability to bind the potted soil attached to the roots wrapped in straw and to use the elasticity of the rubber band to bind the seedlings is 500 per day, which is a high binding ability and even an amateur can easily bind. If a rope is used, the skilled worker has only 300 abilities a day. Also, after transportation and transplantation, it is desired that the binding of the potted soil that adheres to the roots quickly disintegrates in the soil in order to improve root viability and growth, so that disintegration in the soil is much slower than flies. When the rubber band is buried in the soil, some workers bury it as it is, but it seems that there are many workers who remove the rubber band and bury it. In particular, in order to bury potted soil that adheres to the roots of plant trees used for greening of public institutions in the soil while surrounding and binding it, it may be mandatory to wind it with a fly. On the other hand, in the case of large and medium trees, as shown in Fig. 1, the pot soil attached to the roots is wrapped with linen cloth, rice paddy, and straw, wrapped around the neck with a rope, and tied with the rope. Alternatively, as shown in FIG. 2, the pot soil adhering to the root is tightened, and the pot soil adhering to the root is wound with a straw rope so as not to shake the pot soil adhering to the root. However, the selling points of large and medium trees used for garden trees are tree shape and roots. No matter how good the shape of the tree is, it will have no commercial value if it has poor root survival after being transported from a production area to a consumption area or transplanted. Therefore, this operation is extremely important, and the straw fly is wound up evenly and firmly so that the potted soil attached to the root does not collapse during transportation. However, when a straw roll is wound, if a thick root is conveniently present, a straw fly can be wound with the support as a support. If not, a straw roll is driven into a pot soil attached to the root as shown in FIG. The potted soil attached to the roots is not the same size for all the plants, but has various sizes and shapes.The soil varies from sandy to clay, and the soil attached to the roots with straw rope is loaded during transportation. It is very difficult to roll uniformly and firmly so that it does not collapse, and requires a considerably skilled worker. In other countries, when the land is frozen like a bedrock, it is cut open with a plow, and the root and frozen soil are lifted together and moved, and the frozen ground method, in which the root is surrounded by a square or circular plate ( (See Fig. 4), cloth wrapping method using cloth and wire, wire mesh, etc. is performed, but as a transplanting technique, it is a rough technique, It is said to be the best in a unique way.

[0003]

The method of tying using a fly requires skill and time for sieving, but has the convenience of being able to be buried in the soil while keeping the rope tied. The method of tying linen, sackcloth, or straw with a rubber band is very easy at the time of tying and has the advantage of greatly improving the tying work capacity. There is a problem that the rubber band cannot be embedded as it is in order to improve the vigor and growth of the rubber band, and it is difficult to handle because the rubber band is removed at the time of embedding.
Also, as shown in FIGS. 1 and 2, instead of surrounding and bundling the pot soil attached to the root with a rope, linen cloth, straw, or straw, a binding cloth made by weaving or sewing a rubber tape or a rubber net or thread rubber is stretched. It is found that it is very easy to wrap and bind the potted soil with the roots wrapped in straw and wrapped with straw using the elastic action of rubber, but this rubber component is composed of rope, burlap, komoko and straw. On the other hand, disintegration in the soil is very slow, and it is not preferable to bury it in the soil as compared with ropes, considering the root viability and growth after transplantation. However, the rubber composition excellent in the ease of bundling the potting soil, a rubber tape, a thread rubber, a rubber net, a rubber composition for producing a binding cloth woven or sewn with thread rubber, a rope in the soil, hemp cloth, When it has the property of disintegrating earlier than or equal to straw, the ties are stretched and tied by the rubber tying tool to keep the potted soil attached to the root during transportation, so that the rubber composition naturally expands and contracts. The potted soil that adheres to the roots can be buried in the soil with the unity. An object of the present invention is to provide a soil disintegrable rubber composition by focusing on this point. Further, the present invention provides a binding cloth woven or sewn with a rubber band, a rubber tape, a thread rubber, a rubber net, a thread rubber, which is excellent in bundling pot soil using the soil-disintegrable rubber composition. Also aim.

[0004]

According to the present invention, as a result of examining the disintegration property of rubber products in soil, the rubber tying tool is in a stretched state in which the rubber tying tool is stretched to wrap the potting soil attached to the root. Even if the composition itself does not disintegrate, the water-soluble additive that elutes in the soil contained in the soil-disintegrable rubber composition dissolves into the soil due to the moisture in the soil, and when it becomes a sponge state, the tensile strength decreases and tearing occurs The soil disintegration is obtained by adding and mixing 3 to 70 parts by weight of a water-soluble additive which does not bind to the rubber component and elutes in the soil with respect to 97 to 30 parts by weight of the rubber composition. Rubber composition. The mixing ratio of the rubber composition and the water-soluble additive is determined by the modulus, tensile strength or elongation (at least 2 to 2) of the rubber physical property having the minimum binding force required to prevent the loosening of the potted soil attached to the root during transportation. Determined by a combination of the three-fold stretchability) and the root survival rate after transplantation and the desired disintegration rate for disintegration (disintegration after at least 7 months in soil). When high modulus and high tensile strength are required, the amount of the rubber composition is increased, while when the disintegration rate is desired to be increased, the amount of the water-soluble additive is increased. It depends on the type of water-soluble additive, or it has the minimum necessary binding force to prevent collapse of the potted soil attached to the root when transported, and it has a rubber property of three times elongation, one-month cleavage. It is advisable to adjust as required based on the disintegration rate.

[0005]

According to the present invention, the water-soluble additive is not bonded to the rubber component but dispersed in the matrix of the vulcanized rubber component constituting the elastic body. The elastic additive is eluted from the elastic body to make the elastic body porous. Since this elastic body is stretched and stretched to create a binding force for the surrounding bundling of the potted soil attached to the roots, the tensile strength before being buried in the soil is significantly reduced, leading to splitting. Will be.

In order to promote the cleavage of the elastic body in a tensile state, it is preferable that the rubber component also has biodegradability in the soil, and natural rubber having a polyisoprene structure and synthetic natural rubber are used as the rubber component. Is preferred. Incidentally, the main components of natural rubber are rubber hydrocarbons, proteins, fatty acids, sugars and ash. In the soil,
It contains a small amount of oxygen that oxidizes and decomposes the rubber component, and is active by filamentous fungi, actinomycetes, and bacteria that decompose organic substances. The rubber component is composed of water content, temperature, PH, and oxygen content in soil. Decomposition occurs at different speeds depending on the type of other organic substances. In addition, as a vulcanizing agent, methylene bi
Combination of scan acrylamide as vulcanizing agent, it is preferable to promote disintegration of the cross-linked structure of the rubber matrix in the soil. As the natural rubber and the synthetic natural rubber having a polyisoprene structure as the rubber component, a solid, liquid, or powdered polymer having a different shape by vulcanization or molding may be used. As a method for vulcanizing the rubber composition, steam, electric heat, hot water, hot air, salt bath, radiation, or electromagnetic waves may be used. As a method for molding the rubber composition, extrusion, dipping, mold, and rolling methods may be used.

The water-soluble additive may be any water-soluble substance that does not bind to the rubber component, but is preferably one that does not harm the transplanted seedlings and planted plants. A nitrogen-based water-soluble fertilizer, a phosphate-based water-soluble fertilizer, and a potassium-based water-soluble fertilizer that improve the rate or promote growth are most preferred. As the water-soluble additive, one or more selected from the group consisting of carboxymethyl cellulose, casein, starch, lecithin, a coagulant, a nitrogen-based water-soluble fertilizer, a phosphate-based water-soluble fertilizer, and a potassium-based water-soluble fertilizer are used. Is done.

Lecithin naturally exists in important organs of animals and plants and plays a key role in life phenomena. Lecithin is abundantly contained in yolk, animal brain pulp, soybean seeds, and the like. It is mainly industrially extracted from soybeans on a large scale. As the coagulant, Diaclear manufactured by Mitsubishi Kasei, a water-soluble polymer obtained by linearly polymerizing acrylamide can be used. Such coagulants are used in industrial water treatment and municipal sewage treatment. As the nitrogen-based water-soluble fertilizer, ammonium sulfate, salt ammonium, Chile saltpeter, ammonium nitrate, urea, lime nitrogen, lime nitrate and the like can be used. As the phosphate-based water-soluble fertilizer, there can be used monoammonium dihydrogen phosphate, calcium dihydrogen phosphate superphosphate, lime superphosphate and the like. Potassium-based water-soluble fertilizers include potassium sulfate, potassium chloride, potassium sulfate, caustic acid, plant ash, and compost. Further, a soil conditioner may be added in addition to the water-soluble additive. As this soil conditioner, for example, a soil conditioner containing thiobacillus, a bacterium that oxidizes sulfur, which has the ability to degrade organic substances, may be used in combination. This can promote the collapse of the crosslinked structure of the rubber matrix crosslinked using sulfur.
In addition, Thomas bacteria, urea bacteria, which have the action of decomposing organic substances,
A soil conditioner containing Trichoderma bacteria, cellulose-degrading bacteria, Kofuna bacteria, and mushroom bacteria can be mixed and used. Further, a water-absorbing resin used as a soil conditioner can be mixed and used.

Using the above rubber composition, pottery tying tools for potted soil adhered to various roots are manufactured. First, since the bundling force and bundling workability of potting soil attached to the root and the production cost are low, for the seedlings, the rubber component having a polyisoprene structure is not bonded to the rubber component for 97 to 30 parts by weight,
A mixture comprising a disintegrable rubber composition in soil obtained by adding and mixing 3 to 70 parts by weight of a water-soluble additive eluted in soil is extruded into a tube, vulcanized and then cut into a predetermined width to produce a mixture. A potted rubber band attached to a root for plant transplanting having a wall thickness of 0.15 to 10.0 mm is preferable.

In addition, the potting soil attached to the roots has various shapes, and the soils have various shapes. Also, since the support supported by the thick roots is used as a support, the binding device that can be stretched is much easier to wind than a straw rope. The unity force is also easy to apply. In addition, rubber compositions having a polyisoprene structure can be used as substitutes for straw ropes for large and medium trees because of the low production cost.
After extruding a mixture consisting of a disintegrable rubber composition in soil obtained by adding and mixing 3 to 70 parts by weight of a water-soluble additive which does not bind to a rubber component and elutes in soil with respect to parts by weight, and vulcanized, The rubber component is not bonded to the rubber component with respect to 97 to 30 parts by weight of the pottery tying rubber tape or the rubber composition having a polyisoprene structure which adheres to the root for transplanting a plant having a thickness of 0.15 to 10.0 mm produced by cutting. , Water-soluble additives eluted in soil 3 ~
