Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a method for growing seedlings of vegetables and the like.

[Prior art]

Conventionally, seeds such as onions have a germination rate of about 70 to 80% if they are not sorted, and even if they are carefully selected by wind selection, salt bath selection, etc., the germination rate remains at about 90%.

[Problem to be solved by the invention]

As mentioned above, if the germination rate of seeds is low, the number of seedlings that can be grown in the seedbed per seedbed will also decrease accordingly, resulting in lower seedling raising efficiency. In addition, when growing seedlings one by one at predetermined intervals for use in a transplanting machine, if there is a spot where the seedlings have not yet grown in the -thick seedbed, if the seedlings are fed directly to the transplanting machine, missing plants will occur. .

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention germinates the seeds S in a state where the temperature, light, etc. The seedling-raising method was such that only the selected already germinated seeds S1 were sown in the nursery bed 9 and the seedlings were raised.

【Effect of the invention】

As described above, germinated seeds S1... that have germinated and ungerminated seeds S0... that have not germinated are sorted, and the selected germinated seeds S1
When seedlings are sown only in the seedbed 9, most of the seeds S1... sown in the seedbed grow, so the efficiency of raising seedlings is improved and seedlings suitable for mechanical holly planting can be grown.

【Example】

An embodiment of the second invention will be described in detail with reference to the drawings. The seeds S are onion seeds, and as shown in FIG. 1, they are wrapped in a transparent gel 1 to form a spherical capsule-like seed Sc. This capsule-shaped seed Sc is produced by a capsule-shaped seed manufacturing apparatus configured as shown in FIG. That is, the sodium alginate solution A contained in the container 2a is adjusted to an appropriate flow rate by the cock 2b, and flows down into the gutter 3 inclined at a predetermined angle. Into the solution A flowing through the gutter 3, the seeds S accommodated in the vibrating auto-feeder are discharged in a lined manner and fall at equal intervals. Then, from the lower end of the gutter 3, the solution A of a predetermined size, each drop containing one seed S, is dripped into the Lucium chloride solution B stored in the container 4. go. Solution A, which is dropped one drop at a time into solution B, becomes a transparent, spherical gelatinous gel that envelops each seed S through a chemical reaction.
・Changes to As described above, capsule-shaped seeds Sc...
is created. The capsule-shaped seeds Sc produced in the above manner are stored in a light-shielded germination chamber 5 and kept at an appropriate temperature to germinate (Fig. 3). At this time, the capsule-shaped seeds Sc... It is good to include a germination promoter in the seeds Sc. When germinated by this, the seeds S
In this case, the outer skin has been broken and the bud S has come out. The capsule-shaped seeds Sc that have been germinated are sorted into germinated seeds S1 that have germinated and ungerminated seeds S0 that have not germinated using a sorting device as shown in FIG. That is, the germinated capsule-shaped seeds Sc are stored in a hopper 6 and supplied to a gutter-like transparent sorting guide 7. The capsule-shaped seeds Sc supplied to the sorting guide 7 are arranged in - rows at equal intervals and roll. In the middle of this process, a color sorting means 8 is provided which projects light onto the capsule-shaped seeds Sc and sorts them based on the amount of reflected light. This color sorting means 8 is a conventional one, and is provided with light projection sources 8a, 8a that project light onto the capsule-shaped seeds Sc, and has a color on the projection side that reflects approximately the same amount of light as the objects to be sorted. Seeds to be sorted Sc having a reflection amount other than the background 8b and having a reflection amount other than the background 8b
When the background 8b passes in front of the background 8b, the ejector 8d is configured to eject the background 8b in response to a command from the sensor 8c that detects the background 8b. As a result, when the amount of reflected light from the ungerminated seed SO in which no bud S has appeared is detected based on the amount of reflected light from the already germinated seed S1 in which the bud S has germinated and a white bud S has appeared, the Germinated seeds so are eliminated. In addition, capsule-shaped seeds S
If the outer skin of the seeds S is uniformly colored in a predetermined color before picking the seeds S, the sorting accuracy will be improved. Already germinated seeds S1 are sorted by such a sorting device...

Seedlings are sown and raised. As shown in FIG. 6, the seedling bed 9 is partitioned vertically and horizontally by seedling growers 10 so that one plant can be grown at a predetermined interval.
are made of paper or other materials that corrode in the soil. If the seedlings grown in the nursery bed 9 are directly placed on a transplanting machine, the transplanting machine will separate the seedlings one by one and transplant them into the field. As described above, the germinated seeds S1... that have germinated and the ungerminated seeds S0... that have not germinated are sorted, and the selected germinated seeds S1
When seedlings are sown only in the seedbed 9, most of the seeds $1 sown in the seedbed will grow, improving the efficiency of seedling raising and making it possible to grow seedlings suitable for mechanical transplantation.
