Description

[Detailed description of the invention] This invention aims to suppress deformation and damage to pine seedlings.
This invention relates to a seedling raising sheet for pine seedlings on which bed material to be seeded in rows is placed and supported.

When raising pine-shaped seedlings, it is generally done to add fertilizer to the bed material made of soil, but in this case, forming the bed material becomes troublesome due to the fertilizer content, and the seedling raising process becomes difficult. There was an inconvenience that caused a drop in efficiency.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to improve the efficiency of pine seedling cultivation, which can be conveniently used to improve the efficiency of seedling raising work while suppressing wasteful consumption of fertilizer. The aim is to provide seedling-raising sheets.

The present invention is characterized in that, in the seedling sheet for pine seedlings described above, fertilizer is retained only in a portion of the bed material that corresponds to the lower part of the planned row sowing area.

Next, the effects of the feature configuration of the present invention will be described.

In other words, by allowing the seedling-raising sheet body to retain fertilizer, fertilizer can be supplied to the seeds simply by placing the seedling-raising sheet under the flooring material, thereby improving the efficiency of seedling-raising work. In particular, according to this proposal, fertilizer is retained in the seedling-growing sheet only in the area below the planned row sowing area of the bed material. Therefore, wasteful consumption of fertilizer can be suppressed compared to, for example, retaining fertilizer on the entire surface of the seedling seedling sheet, and as a whole, it is possible to obtain a seedling sheet for pine seedlings that has great practical advantages. I've reached it.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, a seedling growing box 2 loaded with a porous seedling growing sheet 1 made of paper, sponge, etc. and having a rectangular shape in plan view is transported between a pair of conveyor belts 3 and 3.
The seedling raising box 2 is configured to be placed on the top with its longitudinal direction facing perpendicular to the conveying direction, and a plurality of roller pairs for clamping and regulating the position of the seedling raising box 2 relative to the belt are placed in the direction of conveying the seedling raising box. A support frame 7 in which one of the rollers 4a of the pair of rollers is freely rotatably supported on a fixed support shaft 5, and the other roller 4b is elastically biased by a spring 6 on the side of the seedling growing box 2. It is provided in such a way that it can be freely rotated. The seed supply includes a hopper 8 that supplies bed soil A as a bedding material into the seedling raising box 2 being transported, and a seed feed roller 9 for row sowing in which grooves 9a for storing seeds are formed at appropriate intervals in the circumferential direction. The soil-covering hopper 10, the soil-covering hopper 11, and the irrigation nozzle 12 are arranged in parallel in the transport direction of the seedling-growing box 2, so that row sowing into the seedling-growing box 2 can be automatically and continuously performed. It has been done.

Then, the seedling raising box 2 subjected to the above-mentioned sowing treatment is
In the seedling nursery room, the seeds are germinated and rooted while being kept at the appropriate humidity and temperature, and the pine seedlings are grown to be loaded into the seedling stand of the rice transplanter. That is, the pine seedlings are taken out from the seedling raising box 2 along with the seedling raising sheet 1 on which the bed soil A is placed and supported,
The shape-retaining function of the seedling-raising sheet 1 makes it possible to grow pine seedlings that can suppress deformation and damage.
The seedling-raising sheet 1 is loaded onto a seedling stand together with pine seedlings, and is divided and planted as the pine seedlings are divided.

Incidentally, a chemical that is disliked by roots may be applied to the inner surface of the side wall of the seedling raising box 2 so that the pine seedlings can be easily taken out.

As shown in FIG. 4, the seedling-growing sheet 1 is constructed so that the fertilizer H is adhered and retained with glue only in the area of the soil bed A that corresponds to the area where row sowing is planned. By facilitating the
The efficiency of seedling raising work can be improved.
In addition, the roots of the seedlings tend to grow toward the fertilizer H, which prevents the roots of adjacent rows from becoming unnecessarily entwined, resulting in pine-shaped seedlings that are suitable for planting while dividing with a rice transplanter. It is also convenient to obtain.

To carry out the present invention, for example, as shown in FIG.
The means for holding the fertilizer on the seedling growing sheet 1 can be modified in various ways, such as holding the fertilizer in place with glue.

Further, the seedling growing sheet 1 of the present invention can be applied to row sowing by various means, such as when row sowing is performed using a sowing device in which a notch for passing seeds is formed.
