Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for raising seedlings using a seedling mat, which allows seedlings to be transplanted by placing them next to a seedling box every minute when transplanting using a transplanter.

(Prior art and its problems) The conventional method for raising seedlings is to essentially put the seedling base material into a seedling box made of paper or urethane that can be easily divided with transplant nails.
Seeds are sown on top of this, covered with soil, kept warm, and germinated.
There was a method of raising seedlings in which when the seedlings reached a height of about 10 CIK, they were divided and transplanted.

That is, in the conventional method of raising seedlings, the roots grow into the seedling base material to grow into block-shaped seedlings, which are then divided into seedling boxes and transplanted.

However, recently, research has begun on a transplanting method in which young seeds that have just sprouted are separated and transplanted one by one. In other words, the aim of this is that when seeds are grown directly in rice paddies, the germination rate is poor, so it is difficult to sow the seeds by coating them with heavy carbon-coated calcium leaf material, etc., which generates oxygen when it reacts with water. However, there are problems such as not germinating if the sowing depth is deep, and although direct sowing is currently being researched, it still has the problem of being unstable, so it is necessary to transplant seeds in a young bud state. Research is being done.

However, even though the roots of young seeds are intertwined to form a mat, the mat lacks strength and may bend or break, making handling extremely troublesome.

Another problem is that if the seeds are allowed to move freely during germination and seedling raising, the roots of the seedlings become entangled, resulting in a swollen seed mat, making it difficult to separate the seedlings when transplanting.

(Method for solving the problems) In order to solve the above-mentioned problems, the present invention adopts the following growing method.

That is, a seedling raising box (1) having a low peripheral wall that can be filled with 3 to 5 seeds stacked one on top of the other is formed using a material that is easily divided, such as waste paper or pulp.
Paddy rice seeds that have been pre-soaked in water (
A seedling nursery box filled with seeds (a) and sown in layers (
1] was stacked one on top of the other in a suitable number and heated under control to raise a seedling mat.

(Operations and Effects of the Invention) According to the present invention, when the seedling raising box (1) is filled with paddy seeds that are about to germinate and have swollen into a pigeon-chest shape, the paddy seeds are packed in a layer of exactly 3 to 5 grains. . Next, when the appropriate number of seedling boxes (1) filled with this seed rice are stacked one on top of the other to keep them warm, the seed rice will germinate and the roots will grow.At this time, the seedling roots of each seed rice will grow. are intertwined with each other in the seedling nursery box, and young buds (Seed Pine) (A) are grown.

However, according to this growing method, a seedling growing box with a low surrounding wall (1
) The seedlings sown in layers compete to germinate and the seedling roots elongate, so that the seedling roots are sufficiently intertwined with each other to create a seed mat that does not easily collapse. The seed mat can be divided and transplanted accurately, and since the seed mat is stacked and grown, it becomes a thin mat on the top and bottom, so it is easy to divide and handle (3) It produces the effect that can be obtained.

(Example) Reference numeral (1) is a seedling growing box, which is formed into a box shape by recycling waste paper, and the height of the surrounding wall is about 10 to 15 mm. Also, there is no need to treat the bottom plate in particular,
If possible, it is best to make a small hole with a diameter of about 1 to 3 mm.

Also, in order to make it easier to divide it, it is a good idea to make perforations for the base board on this bottom plate. (2) is a heat insulator under the stand (3) with holes drilled on the top and sides. A heater (4) is installed on the side, and the surrounding area and the upper part are covered with a heat insulating cover (5). (6) indicates a heat-retaining mat.

In the seedling box (1) above, fill the seedling box (1) with pigeon-breasted rice seeds (ω) that have been soaked in water for about 3 to 5 days to almost the upper edge, then stack them on the heat insulator (2), and place the seeds at the top. Seedling box (
1] Place the empty seedling growing box (1) and weight it with a board or the like. After that, the entire container is covered with a heat insulating cover (5), and the inside of the container is heated to about 30'0 by using a heater (4) from below.

Then, after 2 to 3 days, the seedlings will germinate and the roots will elongate.
The seedling roots of the rice seeds intertwine with each other and form a mat in the seedling nursery box (1). After 5 to 7 days, the hairy roots of the seedling roots are sufficiently intertwined and try to bite out of the nursery box (1), but because they are stacked, the nursery box (1) is full and dense. A young seed mat (A) is obtained.

An example of a transplanting device for transplanting this young seed mat
This will be explained with reference to the drawings and FIG.

A mat mounting stand (9) consisting of a side frame and a bottom plate that reciprocates from side to side and faces a seedling receiving frame (8) which is L-shaped in side view and is provided with a seedling dividing opening (7). A dividing lug Q on which the young seed mat GA) is placed and intervenes from above in the seedling dividing opening (7).
At l1m, the mat (
A) is divided and transported downward and transplanted to the soil surface.

At this time, this dividing lug αO is placed below the dividing opening (7).
A guide frame αυ with a U-shaped cross section that fits and moves is attached to ensure that the divided pine (A) is transported downwards.

Note that the split lugs Qd are integrally provided on the rotating endless band, and if they are made of flexible rubber material, the seed mat (8) can be less damaged.
