Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for growing crop seedlings using a seedling stand, seedling pot, etc. suitable for transplanting and supplying crop seedlings to a main field.

Traditionally, paper pots, vinyl pots,
Seedling-raising frames and various seedling-raising methods using them have been proposed, but the crop seedlings grown using these methods are not necessarily satisfactory for supplying seedlings to the main field using a transplanter, and it is difficult to continuously grow seedlings in seedling-raising pots. Various defects were observed in the supply and extraction of crop seedlings from seedling pots.

In particular, the present invention provides a method for growing crop seedlings using a seedling stand, a seedling pot, etc., which allows continuous feeding of seedling pots separated from each other and pushing out crop seedlings from the bottom of the seedling pot without any trouble. That is.

To explain embodiments of the seedling-raising stand, seedling-raising pot, and fertilizer filling cover plate used in the method of the present invention, 1 is a bottomless cylindrical seedling-raising pot made of hard material, 2 is a seedling-raising stand, and The seedling raising stand 2 has a plurality of partition plates 4 arranged parallel to each other at regular intervals on a rectangular base plate 3, end plates 5 are provided on both edges of the base plate 3 parallel to the partition plates 4, and One edge perpendicular to the plate 4 has an end plate 5', and the other edge is left open without an end plate.

The end plate 5 and the partition plate 4 on this seedling-raising table 2 and the distance between each partition plate 4 are approximately the same as the outer diameter of the seedling-raising pot 1, and the seedling-raising pots 1 can be placed in alignment on the base plate 3. .

In addition, an appropriate number of small holes 6 for drainage are provided at the mounting position of the seedling pot 1 on the base plate 3 as necessary.

Next, when filling the seedling raising pots 1 arranged and placed on the seedling raising table 2 described above with fertilizer for growing crop seedlings, the manure is poured on the outside of the seedling raising pots 1 as will be described later. Since it is somewhat inconvenient when sending out the seedling growing pot 1 from the seedling growing stand 2, the fertilizer filling cover plate 7 is used to prevent this.

The cover plate 7 for filling with fertilizer is made by placing holes 9 of a size that matches the inner diameter of the seedling growing pot 1 on a thin plate 8 having a larger area than the seedling raising table 2 so that the perforation positions are aligned on the seedling raising table 2. A large number of holes are formed so as to correspond to the positions of the seedling growing pots 1 placed therein, and furthermore, a crosspiece 10 orthogonal to the lower end of the thin plate 8 is provided.
It has a protruding structure.

Such a cover plate 7 for filling with soil is placed on the upper surface of the seedling growing pots 1 which are arranged and placed on the seedling growing table 2, so that the inner surface of the crosspiece 10 is in contact with the outer surface of the row of seedling growing pots 1 orthogonal to each other. By doing so, each company 9 will be placed exactly on each seedling growing pot 1.

In this state, if you put fertilizer on the top of the cover plate 7 for fertilizer filling and stir the fertilizer by hand or using an instrument, the fertilizer can be filled only into the seedling pot 1 through the hole 9, and the seedlings will be raised. pot 1
It will not spill outside.

Since the manure filling covering plate 7 has a larger area than the seedling raising table 2, the manure spilled from the edge of the manure filling covering plate 7 falls outside the seedling raising table 2.

In particular, a fertilizer pressing tool (not shown) having a large number of cylindrical protrusions that fit into holes 9 provided in the soil filling cover plate 7 is particularly suitable.

) to press down the manure filled into each seedling-raising pot 1 from the top surface, the manure in each seedling-raising pot 1 can be compacted to a uniform and appropriate consistency, and the top surface of the manure This allows you to create the necessary space for sowing or transplanting seedlings.

In this way, the seedling raising pots 1, which are arranged and placed on the seedling table 2 and filled with fertilizer, are arranged on the hotbed of the seedling bed, and seeded or seedlings are transplanted (in the case of using the so-called "temporary planting method"). The plants are grown by conventional methods until they reach a size that can be transplanted to the main field.

During this time, watering is performed on the seedbed, and excess water is drained from the small holes 6.

The crop seedlings grown by the method of the present invention are extremely convenient for transplanting and supplying to the main field.

First, in order to supply seedlings, it is necessary that the crop seedlings are grown uniformly, but in the method of the present invention, each seedling raising pot 1 is separated from each other and can be replaced at any time, so that the seedlings can be grown evenly. It is convenient because defective seedlings can be replaced in advance before being supplied.

Next, if we talk about the sequential feeding of seedling pots, when one row of seedling pots 1 on the seedling tray 2 is pushed from the rear end (the side where the end plate 5' of the seedling tray 2 exists), the other end of the seedling tray 2 The seedling pots 1 can be lined up (from the edge without the end plate) and sent out, for example, to a guide path of an automatic seedling feeder (see in particular Japanese Patent Application Laid-open No. 57 186.407 by the present applicant).

After sending out one row of seedling pots 1, move the seedling table 2 one row in a direction perpendicular to the sending direction of the seedling pots.
The next row of seedling growing pots 1 can be arranged and sent out after the previous row of seedling growing pots 1.

Furthermore, regarding the extraction of crop seedlings from the seedling raising pot 1, a seedling drop hole of the same size as the inner diameter of the seedling raising pot is provided at the bottom of the guide passage of the automatic seedling feeding device, and the seedling raising pot is placed above the seedling dropping hole. If the holding part of the crop seedling is pushed down, the crop seedling can be pulled out from the bottom of the seedling raising pot 1 along with the holding soil.

As described above, the work of replacing defective seedlings, the work of arranging and feeding seedling pots, and the work of extracting crop seedlings from the bottom of the seedling pot are all easy, and this means that the method of the present invention can be connected to an automatic seedling feeding device to the main field. This indicates that the method is suitable for growing crop seedlings for use as a seedling.

Furthermore, it is convenient for transporting crop seedlings as they can be handled while remaining on the seedling stand.
