Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an extremely novel seeding sheet for various seed plants, including seeding for raising paddy rice seedlings.

(Conventional Technology) Conventionally, in the sowing and raising of various seed plants, including the sowing for raising paddy rice seedlings, a series of seedling raising steps begins with sowing each seed grain into a certain soil such as a seedbed. Therefore, for various seed plants, regardless of whether they are edible or not, sowing seed grains is an important and essential operation that must be performed first in the seedling-raising process.

Conventionally, the sowing methods themselves include row sowing, spot sowing, and (sprinkling) methods, but in any sowing method, the sowing time is determined by the type of crop, etc., and the climatic conditions of the area where it is cultivated. It was something that could be done.

Here, among various seed plants, for example, regarding the growth of paddy rice, apart from methods such as direct sowing cultivation in paddy fields, in transplant cultivation that requires rice planting, each step from sowing seeds to raising seedlings of the seeds is essential. It is something. When sowing, the amount of sowing and the distribution must be appropriate depending on the type of rice seed, which is extremely troublesome and time-consuming. In addition, when raising seedlings, after sowing in various forms of seedlings such as water seedlings or covered land seedlings,
Until the ff seedlings are transplanted into paddy fields, various extremely labor-intensive seedling-raising managements are required, including fertilization and pest control.

Therefore, there has been a strong desire for a new technology that can sow seeds without being affected by the climatic conditions of the cultivation area and that does not require time and effort in sowing and seedling management. There has been a strong desire for the emergence of such technology in the fields of sowing and raising seedlings, especially for paddy rice among various seed plants.

(Problems to be solved by the present invention) The present invention has been developed in view of the above-mentioned conventional situation,
The purpose is to be able to sow not only various seed plants, but especially seeds for raising paddy rice seedlings at all times, regardless of the climatic conditions of the cultivation area, and to make sowing work and seedling management extremely simple. The purpose of this invention is to provide a novel seeding sheet.

[Configuration of the present invention]

(Means for solving the above-mentioned problems) The present invention is made of a material that dissolves or assimilates into the soil over time, such as a culture medium made of pulp wood, rock wool wood, or any other appropriate material. A seeding sheet is formed by attaching seeds of appropriate natural or artificial seed plants, including seeds for raising paddy rice seedlings, to the sheet surface by an appropriate means such as pasting or embedding. Further, appropriate fertilizers, nutrients, medicines, etc. suitable for seeds and seedlings can be distributed simultaneously or separately on the seeding sheet itself.

According to the present invention, there is no need for all the troublesome efforts of sowing and raising seedlings as in the conventional methods,
The seeding work is completed by simply burying the sheet with the seeds attached in the soil or placing it in an appropriate seedling-raising box.
Subsequent seedling management can also be made extremely simple.

(Embodiments of the present invention) Hereinafter, embodiments of the seeding sheet according to the present invention will be described with reference to the attached drawings.

The technology of the present invention involves sandwiching the seeds 2 of a suitable seed plant such as seeds for raising paddy rice seedlings with film-like upper and lower sheet surfaces 1.1 made of an appropriate material such as pulp material as described below, and using appropriate means. Seeds 2 are attached to the sheet surface, and the whole is formed as a single seeding sheet A.

The material of the film-like upper and lower sheet surfaces 1, (2) is not particularly limited, but only the sheet surface may be made of a material that dissolves in the soil over time or assimilates with the soil. Examples of the material include pulp material, rock wool material, and a culture medium made of various materials.

In addition, the seeds z held between the upper and lower surfaces L and 1 may be seeds of various seed plants, including seeds for raising paddy rice seedlings, and it does not matter whether they are natural seeds or artificial seeds. , and each upper and lower sheet surface 1. The amount of seeds 2 held by t, that is, the amount of sowing and the distribution, etc.
It is specifically determined and standardized depending on the type of each seed to be held.

Note that as the means for holding the seeds 2 between the upper and lower sheet surfaces l, 1, any holding means may be used as long as the seeds 2 are held between the inner surfaces of each sheet surface, for example, in a stuck state. The seed 2 is placed on the sheet surface 1. l
There are various methods, including burying it in the ground.

The seeding sheet A according to the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the gist. Techniques that can apply fertilizers, nutrients, pesticides, etc. for controlling pests and diseases may be applied to the sheet surface itself or between the seeds held between the seeds and seedlings. For example, appropriate fertilizers, nutrients, medicines, etc. may be distributed in advance. It should be noted that fertilizers, nutrients, medicines, etc. can be distributed simultaneously or individually.

In addition, as a modified embodiment of the present invention, although the illustrated example shows the upper and lower sheet surfaces 1.1, the upper and lower sheet surfaces are not necessarily necessary, and only one of the sheet surfaces is used. The seeding sheet A may be formed. In short, it is sufficient that the seeds 2 are attached to the sheet surface and the entire seeding sheet A is formed as a single sheet.

Furthermore, in the present invention, the seeding sheet A itself does not necessarily need to be formed as a film-like sheet, and may be formed as a cassette-like sheet having an appropriate thickness. are shown in Figures 3 to 4.
As shown in the figure, culture medium layers 3, 3 of appropriate thickness made of various materials are joined to both the upper and lower surfaces of the sheet surface l on which the seeds 2 are attached, and the entire sheet surface is sandwiched between the upper and lower culture medium layers. Seeding sea) A can be mentioned.

Hereinafter, the usage status of the seeding sheet A formed according to the present invention will be explained.

First, according to the seeding sheet A according to the present invention, the seeding operation itself becomes extremely simple. That is, when sowing, the sowing sheet A itself, whose sowing amount and distribution shape etc. are specifically determined and standardized according to the type of seeds 2 held between the upper and lower sheet surfaces 1 and 1, is After burying the seeding sheet A, which only needs to be buried in the soil, the sheet surface itself dissolves in the soil or assimilates with the soil over a certain period of time, and the seeded seeds in the stylized form remain in the soil. The quantity and distribution of seeds will remain sown in a very orderly manner.

In addition, as in the embodiment shown in FIGS. 3 and 4,
In the case where the entire sheet surface is sandwiched between the medium layers 3 on the upper and lower sides of the sheet surface to form a seeding sheet A, the seeding sheet A is not buried in the soil, but the top surface is opened and the sheet A is It is sufficient to simply insert the seedlings into a suitable seedling-raising box 4 formed to match the size of the seedlings.

Fertilizers, nutrients, etc. suitable for seeds and seedlings are added to the sheet surface itself or between the seeds attached to it.
If this technology is implemented by distributing chemicals, etc., fertilizers, nutrients, and pesticides for controlling pests and diseases will be automatically applied to the seeds 2 as the sheet surface naturally dissolves or assimilates with the soil. can do.

After the seeding sheet A is buried in the soil or placed in the seedling-raising box, a certain amount of moisture is added at a set date and time, and the seedling-raising process is completely unnecessary. Seedlings of various seed plants, including those for transplanting paddy rice (rice planting), can be grown in an extremely rational manner. In the seeding sheet A of the present invention, in which the sowing amount and distribution of the seeds attached to the sheet surface are specifically determined and standardized, the seeds to be sown are It is possible to eliminate wastage of seedlings and reduce the amount of seeds, and it is also possible to raise seedlings uniformly after sowing, and furthermore, by the phenomenon of uniformity of seedling raising, it is possible to raise seedlings with good disease resistance and reduce the amount of fertilizer applied when raising seedlings. This makes it possible to perform extremely rational rice cultivation.

[Effects of the present invention]

According to the present invention described in detail above, by attaching seeds to a film-like sheet surface and forming this as a single-sheet seeding sheet A, seeds for raising seedlings of not only various seed plants but especially paddy rice can be grown. The seedlings can be sown at any time without being affected by the climatic conditions of the cultivation area, and it is extremely easy to sow seeds without any of the troublesome labor of the seedling grower as in the past.
It is possible to realize a new and innovative seeding sheet A that allows easy and rational seeding work and seedling raising management.
