DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coated seed whose surface is coated with a functional substance such as a soil conditioner, a pesticide, and a fertilizer.

[0002]

2. Description of the Related Art As a conventional coated seed of this kind, there is known one in which a functional substance such as an agricultural chemical or a rooting agent is coated on the surface of a seed using an organic oil such as an edible oil as a binder. .

[0003] As a soil improver which is a kind of a functional substance, for example, a soil improver disclosed in Japanese Patent No. 264057 is known. This soil conditioner is formed in a powder form, and can be mixed with the soil or sprayed on the soil to improve the drainage property of the soil.

[0004]

However, in conventional coated seeds, the organic oil used as a binder may cause mold generation.

[0005] In addition, when the soil conditioner disclosed in Japanese Patent No. 264057 is added to, for example, field soil, the operation of mixing or spraying the soil conditioner on the soil is added to the usual work. Required. For this reason,
There was a problem that extra labor and time were required. Furthermore, since this soil conditioner is used by spraying it over the whole field or the whole ridge, there is a problem that the amount of the soil conditioner used increases because it is added unnecessarily to the non-rooted portion of the crop. .

The present invention has been made by paying attention to the problems existing in the prior art as described above. The purpose is to prevent the occurrence of mold and to add the functional substance to the soil without extra labor and time, and to reduce waste and reduce the amount of the functional substance used. It is an object of the present invention to provide a coated seed capable of suppressing the occurrence of a seed.

[0007]

In order to achieve the above-mentioned object, a coated seed according to the present invention according to the first aspect of the present invention comprises a coating layer mainly composed of a functional substance and an inorganic oil as a binder on the surface of the seed. Is formed.

The functional substances used in the present invention include soil improvers, pesticides (plant growth regulators such as insecticides, fungicides, herbicides, rooting agents, fungicides, bird repellents, etc.), Fertilizers and the like can be mentioned, and these can be used alone or as a mixture of two or more of them.

Inorganic oils used as binders include kerosene, light oil, gasoline and the like. The coated seed of the present invention is produced, for example, by the following three methods.

[0010] In the first production method, first, the seed is immersed in a binder, and then the functional substance is sprayed on the seed. Then
The functional substance adheres to the surface of the seed via the binder to form a coat layer.

In the second production method, a paste is formed by mixing a functional substance and a binder, and the paste is coated on the surface of a seed to form a coat layer. When forming the paste, it is preferable to mix the functional substance and the binder in equal amounts.

As a third manufacturing method, a tumbling method may be used. That is, put the seeds in a container that rotates or vibrates,
A coat layer is formed by dusting the seed with a functional substance and a binder while rotating or vibrating. When the seed is coated with the functional substance and the binder, the functional substance and the binder are preferably in the same amount.

When the coated seed of the present invention is sown in a field, for example, the binder in the coat layer is dispersed in the soil by the moisture in the soil, and the functional substance is diffused into the soil accordingly. At this time, the functional substance diffuses around the seed to the range of a sphere having a diameter of 30 to 40 cm, and the functional substance exerts its effect in that range.

According to a second aspect of the present invention, there is provided the coated seed according to the first aspect, wherein the inorganic oil is kerosene. According to a third aspect of the present invention, there is provided the coated seed according to the first or second aspect, wherein the functional substance is at least one selected from a soil conditioner, a pesticide, and a fertilizer. Things.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the present invention is applied to a coated seed whose surface is coated with a soil conditioner will be described below.

In this embodiment, a soil conditioner is used as a functional substance, for example, the soil conditioner disclosed in Japanese Patent No. 264057. This soil conditioner is a mixture of ferrite, iron oxyhydroxide or maghemite, and boehmite alumina, or ferrite, iron oxyhydroxide or maghemite,
It is obtained by blending boehmite alumina and a calcium phosphate compound. These can improve the drainage property of the soil only by adding a small amount to the soil, and the latter soil improver is particularly effective.

Kerosene is used as a binder, so that the soil conditioner can be adhered to the surface of the seed,
A coat layer mainly composed of a soil conditioner and kerosene is formed on the surface of the seed.

The amount of the soil conditioner coated on the seed is 100 to 1000 for a field having an area of 10 ares.
g, preferably 300 g. When producing the coated seeds, the seeds are first immersed in kerosene, and then the seeds are dusted with a soil conditioner. Then, the soil conditioner adheres to the seed surface via kerosene to form a coat layer.

As described above, according to this embodiment, the following effects are exhibited. -Since kerosene, which is an inorganic oil, does not contain nutrients necessary for mold growth unlike organic oils such as edible oil, the use of kerosene as a binder can prevent the occurrence of mold.

Since the surface of the seed is coated with the soil conditioner, the soil conditioner can be added to the soil simultaneously with sowing by sowing the coated seed. Therefore, conventionally, when adding a soil conditioner to soil, the work of mixing or spraying the soil conditioner with the soil was required in addition to the usual work, but the work can be omitted. . Therefore, the soil conditioner can be added to the soil without extra labor and time. Particularly, in the case of a large-scale farm, the effect is remarkable because a great deal of labor and time are required for the method such as spraying.

The soil conditioner is diffused into the soil from the coat layer of the sown coated seeds, and therefore is added only to the soil around the seeds, and is not added to the part of the root that is far from the seeds and cannot reach the roots. . Therefore, wasteful addition can be eliminated, and the amount of the soil conditioner used can be reduced.

The soil conditioner is diffused into the soil from the coat layer of the sown coated seeds, and is therefore reliably added to the soil around the seeds. Therefore, the effect of the soil conditioner can be reliably imparted to the seed and the roots emerging from the seed.

Since the coat layer can prevent moisture in the air from penetrating into the seeds during storage, the seeds can be stored in a dry state, and germination failure due to moisture absorption is prevented. Can be.

Kerosene has a better dispersibility in soil than heavy oil having a high viscosity. Therefore, kerosene can be promptly used not only on soil with high moisture such as paddy fields, but also on soil with low moisture such as dry fields and open-field cultivated fields. Are distributed. Therefore, by using kerosene as the binder, the diffusibility of the soil conditioner into the soil can be improved, and there is no possibility that the coat layer will become an obstacle during germination.

By using kerosene as a binder, material costs can be reduced. -The seed layer is immersed in kerosene and then sprinkled with the soil conditioner, whereby the soil conditioner adheres to the surface of the seed via the kerosene, so that a coat layer can be easily formed.

The above embodiments may be modified as follows. -Mixing a soil conditioner and kerosene to form a paste, and modifying the paste to form a coat layer by coating the surface of the seed.

[0027] Even with such a configuration, a coat layer can be easily formed on the surface of the seed. -Putting the seed in a container that rotates or vibrates, and applying a soil conditioner and kerosene to the seed while rotating or vibrating so as to form a coat layer.

Even in the case of such a configuration, a coat layer can be easily formed on the surface of the seed. Next, technical ideas that can be grasped from the embodiment will be described below.
