The present invention relates to a gel coated seed technique wherein the seed is coated with an aqueous gel.

Gel-coated seeds disperse water in plant seeds, seed analogs (including tissues such as fragments or tubers) such as pears or wild pears that are capable of growing (hereinafter referred to as "seeds"). It is enclosed in a coating gel layer consisting of water and an aqueous gel composed of a dispersoid (Patent Document 1), so that seedlings can be reliably harvested from a single seed by water and other components constituting the coating gel layer. It is a completely groundbreaking technology, and this certainty allows the use of excellent and very expensive F ₁ seeds, resulting in a significant improvement in yield and quality.

Such gel-coated seeds are enclosed with a seed in a gel-forming aqueous solution mainly composed of sodium alginate, for example, and an aqueous solution having a metal ion such as divalent or higher metal ion, such as calcium, barium or aluminum, which solidifies the gel-forming aqueous solution. It is known to have a spherical to granular product obtained by dropping in an aqueous solution of an equivalent salt or the like and gelling by reacting sodium alginate around the seed with these metal ions.

These gel-coated seeds are widely used in vegetables, flowers, etc., and can be sown after checking the state of germination by a transparent coating gel layer, and thus, they have been attracting attention as a science textbook for elementary school students and have been actually used.

When the gel-coated seed according to the prior art is sown in the field, it is necessary to purchase a new wave device or by human hand for the wave wave.

[Patent Document 1] Japanese Patent Application Laid-Open No. 9-15

An object of the present invention is to provide a gel-coated seed which improves the above-mentioned conventional problems, i.e., it is easy to sow without special apparatus without impairing the effect of the conventional gel-coated seeds, and also capable of being energized in sowing.

In order to solve the said subject, the gel-coated seed of this invention is a gel-coated seed which has a some seed distributed in the said longitudinal direction in the coating gel body of elongate length of at least one direction as described in Claim 1.

Moreover, the gel-coated seed of this invention is a gel-coated seed of Claim 1 as described in Claim 2 WHEREIN: It is characterized by the said coating gel body being string-shaped or strip | belt-shaped.

The gel-coated seed of the present invention is characterized in that, as described in claim 3, one or more seeds are arranged in the gel-coated seed of claim 2 at intervals in the coated gel body, respectively.

The gel-coated seed of the present invention is characterized in that the interval is constant in the gel-coated seed according to claim 3 as described in claim 4.

The gel-coated seed of the present invention is characterized in that, in the gel-coated seed according to any one of claims 1 to 4, as described in claim 5, a reinforcing fiber body is disposed in the coated gel body so as to be reinforced in the longitudinal direction.

The gel-coated seed of the present invention is characterized in that a coloring material and / or a flavor is added to the gel-coated seed according to any one of claims 1 to 5 as described in claim 6.

The gel-coated seed dried body of the present invention is characterized by drying the gel-coated seed according to any one of claims 1 to 6 as described in claim 7.

As the gel in the gel coated seed of the present invention, a general aqueous gel used for the gel coated seed can be used.

One or more kinds of natural and synthetic gel-forming polymers selected from sodium alginate, zeran gum, xanthan gum, locust bean gum, carboxymethyl cellulose, pectin, gelatin, carrageenan, sodium polyacrylate and agar, etc. And formed by water. Moreover, among these, metal ions may need to coexist for gelation, and the salt, alkali, etc. which supply these metal ions are added suitably. Moreover, various preservatives, fertilizer components, growth promoters, etc. can also be added suitably as a 3rd component.

As aqueous solution which forms an aqueous gel with such metal ion, aqueous solution, such as sodium alginate and sodium polyacrylate, is mentioned. Divalent metals, such as calcium and barium, and aluminum are used as metal ions which harden | cure these as an aqueous gel, and these are normally used as aqueous chloride solution in order to prevent the bad influence to a plant object.

As the aqueous gel-forming aqueous solution, an aqueous solution of carboxymethyl cellulose and an aqueous solution of potassium aluminum sulfate (potassium alum) may also be used as the coagulating solution.

It is preferable to make water content of the coating gel body in this invention into 90% or more. If the moisture content is less than 90%, the coated gel may harden, which may interfere with the protrusion of the plant (the shoots or roots come out of the coated gel) and finally die or deform and grow to become unsuitable as commodity crops.

The gel-coated seed of the present invention coagulates the gel-forming aqueous solution by, for example, supplying a gel-forming aqueous solution to the outer nozzle using a double-pipe nozzle, and having a seed formed therein by feeding the seed to the inner nozzle. It can obtain by making it coagulate | solidify (gelate) by introducing into the solution (coagulation liquid) containing the metal ion which has the effect | action to make. At this time, it may become a string or strip | belt-shaped thing according to a change of nozzle shape.

Moreover, when it is left as it is after solidification, hardening of a gel body will advance and the sprout and root after germination may not protrude to the exterior of a gel body, and it washes with water as needed, and removes an excess coagulation component.

The gel-coated seeds of the present invention may be used as prepared as described above, but may be dried as necessary in the same manner as the conventional gel-coated seeds for transportation or storage, and in that case, in water before use It can be easily restored and used by means, such as immersion. Moreover, the gel-coated seed (called "gel-coated seed dry body") of such a dry state is also included in this invention.

In drying, it is necessary to carry out under conditions that do not damage the seeds. Such drying methods include ventilation drying, warm air drying at a relatively low temperature (about 50 ° C.), vacuum freeze drying, various drying agents (calcite lime, lime chloride, silica gel, Drying using lithium chloride).

In the gel-coated seed of the present invention, in the case of the cord-shaped coated gel, the thickness is usually 1 mm or more and 15 mm or less, depending on the size of the seed disposed therein. If the thickness is less than 1 mm, the strength required for handling cannot be obtained. If the thickness is more than 15 mm, shoots and roots after germination cannot protrude to the outside of the gel, which may cause problems such as growth failure. Moreover, there is no restriction | limiting in particular as cross-sectional shape of a string-like coating gel body, A circle, an ellipse, or a polygon may be sufficient. Further, the coating gel body may be a string having a width, i.e., a band, and the same handling as in the case of the string coating gel is possible.

The length of the gel-coated seed of the present invention is not particularly limited as long as it can be handled. However, considering application to rice fields and fields, workability can be improved by, for example, 10 m or more. In addition, in the case of a string form or a strip | belt shape, the gel-coated seed of this invention can be handled easily by the method of accommodating, winding | winding with a reel, etc., hanging in a storage container.

In the present invention, as a seed to be enclosed in a string-like strip of gel, a pellet seed formed into a spherical shape with fine diatomaceous earth can also be used.

In the present invention, when one or a plurality of seeds are arranged at intervals in the string-to-belt coating gel body, the plant after germination is developed by simply spreading the string-like coating gel along the ridges, straight lines or curves and sowing in the field. The space required for growth can be secured, and labor such as thinning can be unnecessary. Here, the interval is more preferably a constant interval.

Further, only one kind of seed may be disposed in the string-like coating gel, or other kinds of seeds may be disposed in l string or band-like coating gel bodies as necessary, such as by placing flowers seeds of different colors. It may be.

Seeds are preferable at regular intervals in the longitudinal direction of the coated gel body, particularly when the necessary spaces are secured so that the growth of the plant is not hindered, since the removal after seeding into the field is not necessary, and the growth does not occur. In addition, seeds may be arranged singly or plurally, depending on the nature of the plant or the germination rate of the seeds.

In addition, since the coated gel is made of an aqueous gel, it is relatively weak in strength. For this reason, in order to improve the operability by increasing the strength in the longitudinal direction, reinforcing fiber bodies such as yarns (strands, spun yarns), strings, or short fibers may be disposed therein. The reinforcing fibers such as yarns and strings are preferably made of natural fibers or synthetic fibers that are naturally decomposed in a field because no labor such as recovery or disposal is necessary. In the case of reinforcement by short fibers, for example, it is realized by mixing these short fibers in a gel-forming aqueous solution, and in the case of reinforcement by threads or strings, these fibers may be supplied from the nozzles on the inner side, Or you may supply these fiber bodies to the liquid flow of the gel formation aqueous solution which came out from the nozzle. In addition, not only one string or thread may be reinforced by a plurality of lines.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated using drawing.

1 shows a model diagram of a gel coated seed (having a string-like coated gel body) according to the present invention. In Fig. 1 (a), one seed is arranged at a predetermined interval in a string-like coating gel, and in Fig. 1 (b) a plurality of seeds are arranged at regular intervals (two in this example) in a string-shaped coating gel. For example, Fig. 1 (c) shows a state in which the gel coated seeds according to the present invention are dried.

Such a gel-coated seed can be manufactured using the apparatus shown in FIGS.

As shown in Fig. 2 (a), the aqueous gel-forming aqueous solution 2 inside the aqueous gel-forming aqueous solution tank 1 is subjected to the aqueous gel-forming aqueous solution tank by the pressure of air introduced from the air inlet 1a. (1) It is supplied to the nozzle 4 by the piping 3 from the bottom part.

The nozzle 4 is a double tube, and the aqueous gel-forming aqueous solution 2 is supplied to the nozzle 4 exterior, and the aqueous gel-forming aqueous solution 2 is discharged from the lower opening 4b of the nozzle 4 exterior. It flows and flows toward the coagulation liquid tank 5 below the nozzle 4. The upper part of the inner tube of the nozzle 4 becomes the upper opening 4a (refer FIG. 2 (b) and FIG. 3) of the upper part of the nozzle 4, and a seed can be thrown in in this upper opening 4a. Although seed may be carried out by hand, it can be performed automatically by a manipulator or by modifying various seeding devices. Here, the arrangement | positioning interval of the seed of the longitudinal direction in a coating gel body can be adjusted by adjusting the timing of this seed addition mainly.

4, the model figure of the seed supply part which produced | remodeled such a seeding apparatus is shown. In this example, the number of seeds (two in this example) suitable for the size of the cutout is supplied from the hopper to the cutout provided in the rotating disk, and the lower part of the seed supply part is rotated by the rotation of the rotating disk (rotating at a constant speed). A certain number of seeds is supplied regularly.

In the above apparatus, although the lower end of the nozzle 4 is located above the liquid level of the coagulating liquid 5c of the coagulating liquid tank 5 in this example, the lower end of the nozzle 4 may be positioned in the coagulating liquid 5c. . However, when the lower end of the nozzle 4 is located above the liquid level of the coagulating liquid 5c of the coagulating liquid tank 5, there is no fear of clogging inside the nozzle 4.

Since the coagulation liquid 5c of the coagulation liquid tank 5 is circulated by the conduit 5a and the pump 5b attached to the coagulation liquid tank 5, solidification stain of an aqueous gel-forming aqueous solution does not occur. have. Since the contact time with the coagulating liquid is determined by the time of staying in the coagulating liquid, the length adjustment of the coagulating liquid tank 5 and the adjustment of the extraction speed from the coagulating liquid tank 5 by the roller 6 to be described later, etc. Adjust to get proper coagulation.

The board | substrate 5d is obliquely placed in the downstream end part of the coagulation liquid tank 5 of this apparatus, and the roller 6 is provided in front of it, and is rotated by the motor which is not shown in figure. The thickness of the string-like coating gel of the obtained gel-coated seed is determined by the diameter of the nozzle 4, the amount of the aqueous gel-forming aqueous solution supplied to the nozzle 4, and the rotation speed of the roller 6. In addition, the string-like gel-coated seed is supplied to the roller 6 without a wound by the plate 5d placed at the downstream end of the coagulating solution 5, and the coagulation solution 5 is replaced with the plate 5d. The downstream end of the may be oblique.

Under the roller 6, there is a support colander 9 and a water washing tank 8, and the water washing tank 8 is supplied with running water from the bottom thereof, and drained from the other bottom drain 8a. The string-like gel-coated seed that enters the support colander 9 is washed with this water, and the excess coagulation component sinks to the bottom of the washing tank 8 and is discharged from the drain 8a, so that the cleaning efficiency is high.

Between the roller 6 and the water washing tank 8 there is a splitter plate 7 reciprocating left and right in the drawing, and the string-like gel-coated seeds supplied to the supporting colander 9 are ubiquitous in the supporting colander 9. Since it is not supposed to wash, water washing is performed efficiently.

The upper part of the splitter plate 7 is provided with cutters 17a of various blades attached to the left and right in the drawing, and the string-like gel-coated seeds are appropriately lengthd (for example, 2) during the left and right reciprocating motion of the splitter plate 7. m) (see FIG. 5). In addition, this cutter 7a is not essential, and the string-like gel-coated seed washed with water in the support colander 7 may be wound, for example, with a reel.

The gel-coated seed of the present invention thus obtained is sown as needed and sown in the field. Here, the germination treatment can prevent germination defects or seedling defects.

Here, the gel-coated seed of the present invention can be easily sown only by unfolding in a field (in a field or a house), so that a special seeding plant is not necessary, and sexualization can be achieved.

In particular, in the case of the gel-coated seed of the present invention in the form of a string or a strip, the seeding is very easy because the seeding is only placed along the ridges and only shallowly sown.

In addition, in hydroponic cultivation (hydroculture) etc., in the case of hydroponic cultivation (hydroculture), the gel-coated seed of the present invention can be grown as it is, for example, by swirling and sinking in water.

Moreover, although it is common for plants to be used also as an interior, in order to improve the function as the use, the gel coating seed of this invention may also add coloring agents, fragrances, etc., such as dye and a pigment, to a coating gel body, In that case, it may have a therapy effect.

In addition, in addition to the seed in the coating gel body, for example, for use in a community, other than the seed, for example, an egg of an organism, a color bead, etc. may be put, and these cases are also included in the present invention.

In addition, the gel-coated seed of the present invention can also be suitably applied to the field of rice, which has recently been partially carried out.

In the case of rice direct sowing, seed should be sown by controlling the seeding depth (planting depth) to an appropriate range in the soil below the surface of the water. If the seeding depth is too deep, oxygen is deficient and growth stops and dies. Moreover, when too shallow, it may flow. Although it is possible to further improve and apply the commercially available expensive wave mill and the like, there has been a demand for a method that can be reliably grown by simpler means.

Here, since it is a string-like strip | belt-shaped gel-coated seed, since the loss | disappearance of a seed is completely prevented only by fixing a part of it, for example in the soil surface, it is not necessary to plant it in deep position. In addition, if it does not become entangled, for example by winding on a reel or harvesting in a container, it can be planted easily without a special seeding device.

Here, an example of the method of sowing the gel-coated seed of this invention which has rice seed as a seed inside to a rice paddy is demonstrated using FIG.

Although the cord-shaped gel-coated seeds (containing rice seeds) according to the present invention may be embedded in the soil below the water surface to have a suitable uniform depth, in general, the gel-coated seeds are slightly heavier than water when prepared without bubbles. For example, as shown in Fig. 6 (a), the soil is partially embedded in the soil. The seed can be sown simply by fixing it to the soil surface using a simple fastener as shown in Fig. 6 (b). Can prevent the loss. In addition, since the roots which sprout after sprouting and protrude outside the gel body grow in the soil, the fixture is unnecessary after that. In addition, in sowing into rice fields, it is possible to sow at the same time as harrowing, so that work time can be shortened and labor can be increased.

 According to the gel-coated seeds of the invention, the yield and quality can be greatly improved, similar to the conventional gel-coated seeds, and no special point breaker is necessary. In addition, it is possible to increase the performance in sowing.
