DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a pot seedling having a pot sheet in which upper thin pots are juxtaposed in the vertical and horizontal directions of the pot seedling.

[0002]

2. Description of the Related Art Conventionally, as a method for producing a pot seedling, conventionally, for example, as shown in Japanese Patent Application Laid-Open No. 58-165704, a pot sheet is placed on a mounting table so that a seedling opening of the pot is on the lower side. In this placement state, the soil is supplied into the pot from the large-diameter opening opposite to the seedling opening of the pot, and seeds are supplied into the pot from the large-diameter opening after the covering is supplied, and After the seed supply, floor soil is supplied from the large-diameter side opening into the pot, and after the floor soil supply, the pot sheet is turned upside down so that the seedling opening is on the upper side to germinate seeds and open the seeding opening. The method of extending the foliage from the leaves has been adopted.

[0003]

Conventionally, at the time of sowing, the bed soil covers the seeds and the bed soil layer must be thicker than the cover soil layer. In addition, when the pot sheet is turned upside down, the seedling box is placed on the pot sheet so as to close the large-diameter side opening of the pot, so the soil in the pot tends to be pressurized. The seed weight was sometimes damaged due to the weight of the bed soil acting at the time of sowing and the pressurization at the time of sheet inversion, and the seedling raising rate was sometimes deteriorated. In particular, when seeds that have already germinated are used as seeds, the buds are easily damaged, and thus the seedling raising rate is likely to deteriorate. An object of the present invention is to provide a method for producing a pot seedling, which is relatively easy to supply soil and seeds to a pot sheet, but hardly causes seed damage.

[0004]

According to the present invention, in order to attain the object, the pot sheet is formed in such a manner that the seedling opening of the pot in the pot sheet described at the beginning is formed by the upper end of the vertical wall of the pot. The pot sheet is stored in a seedling raising box with the seedling opening facing upward, and in this housed state, floor soil is supplied into the pot from the seedling opening,
After the supply of the bed soil, seeds are supplied to the bed soil from the seedling opening, and after the seed supply, cover soil is supplied from the seeding opening into the pot, and foliage is extended from the seeding opening. It is characterized by. The operation and effects are as follows.

[0005]

The seedling opening is formed by the upper end of the vertical wall so that there is no wall protruding from the upper end of the pot vertical wall toward the inside of the pot. It is possible to form a seedling opening larger than a conventional pot sheet having an opening, and if a pot sheet having this large seedling opening is used, floor soil, seeds, and cover soil are supplied to the pot through the seeding opening. However, it can be supplied relatively easily with accuracy and speed close to those of the conventional method in which the seeds are supplied from the opening opposite to the opening for opening the seedlings in the pot. Then, if the floor soil, seeds and cover soil are supplied to the pot sheet in that order, and the seedlings are taken out without being turned upside down in the supply state, the soil weight applied to the seeds is extremely small compared to that of the floor soil. Thus, the seeding step can be completed while preventing the pressurization by the reversal of the pot sheet from acting in the conventional method.

[0006]

According to the present invention, by using the above-mentioned seeding opening pot sheet, the above-mentioned supply order of the floor soil, seeds and covering soil is adopted, so that large earth pressure is not applied to the seeds and their buds, so that damage is less likely to occur. And improved productivity.

[0007]

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a potted plant in which an upper slender pot is juxtaposed in the vertical and horizontal directions of the pot seedling, and an upper opening of the upper slender pot is formed with a seedling opening for the pot. The present invention relates to a method for producing a pot seedling using a pot sheet that has been set.

[0002]

2. Description of the Related Art As described above, an upper slender pot is juxtaposed in the vertical and horizontal directions of a pot seedling, and a seedling opening of the pot is formed at an upper end of the upper slender pot. When a pot sheet is used, for example, as compared to a case where a pot sheet is formed by simply pasting a large number of paper cylinders having a constant cross-sectional diameter, the boundary between adjacent seedling blocks is located apart from each other at least on the upper side of the pot. Therefore, when planting mechanically with a planting device equipped with seedling planting claws, it is convenient in that it is easy to divide seedlings for each block, and a pot seedling making method using this kind of pot sheet has also been developed. Was. Conventionally, as a method for producing a pot seedling using a pot sheet having the above-described upper thin pot, for example, as shown in JP-A-58-165704, [1] Using a pot sheet in which the seedling opening of the pot is formed by a small-diameter hole or slit at the upper end of the pot that is parallel to the vertical direction and the horizontal direction, and is thinner at the top, the pot sheet is The seedling opening is placed on the mounting table so that the seeding opening is on the lower side. In this mounting state, soil is supplied into the pot from the large-diameter opening opposite to the seedling opening of the pot, and the soil is supplied. After that, seeds are supplied into the pot from the large-diameter opening, and after this seed supply, floor soil is supplied from the large-diameter side opening into the pot, and after the floor soil supply, the seedling opening of the pot sheet is opened. In the posture to be on the upper side A method in which seeds are germinated and stems and leaves are extended from an opening for raising seedlings by inverting upside down. The pot seedling preparation method of the above [1] has been adopted.

[0003]

According to the above-mentioned conventional method for producing a pot seedling using a pot sheet in which the upper slender pots are juxtaposed in the vertical and horizontal directions of the pot seedling, the pot sheet is supplied when floor soil is supplied. The floor soil is supplied with the large-diameter opening of the pot on the opposite side of the seedling opening facing upward. At this time, the seeds that need to be located at the top of the pot near the seedling opening during seedling growth are at the stage where the bed soil is supplied with a thin soil layer of approximately
Since the seeds are sown early in the supply of the bed soil, the seed weight of the bed soil layer, which is a layer that is considerably thicker than the cover soil layer, directly acts on the seeds after sowing. Moreover,
The seedling raising box is placed on the pot sheet so as to close the large-diameter opening of the pot already sown when the pot sheet whose seed opening is downward is turned upside down. The soil in the pot tends to be pressurized. As a result, the soil weight acting after sowing, and
The seeds were damaged due to the pressurization of the seeded sheets in the seedling box before inversion and the impact of inverting the seeded pot sheets, and the seedling raising rate was sometimes deteriorated. In particular, when seeds that have already germinated are used as seeds, the buds are easily damaged, and thus the seedling raising rate is likely to deteriorate. Then, in the conventional art, the pot seedlings that have completed the intended seedling growth are removed from the growing field and mounted on a planting device, and when trying to plant seedlings, the pot sheet is placed vertically and vertically. There is a gap between the thinner pots that are arranged side by side in the horizontal direction, and each pot is easier to dry. For this reason, if the waiting time for mounting on the machine is long, there is a problem that the water content of the seedlings is lost or the pot sheet is warped, making it difficult to perform mechanical planting. Further, in this conventional technique, since a large amount of floor soil is supplied from above the seeds after sowing, the position of the seeds in the pot may move, and furthermore, due to the impact when the pot sheet is turned over, Also, there is a possibility that the position of the seed may change, and it is difficult to determine the seed position in a state where the seed is accurately positioned at a predetermined position in the pot. An object of the present invention is to perform the supply of soil and seeds to each pot of a pot sheet having an upper slender pot portion without hindrance, while hardly causing seed damage, and
An object of the present invention is to provide a method for producing a pot seedling that can stabilize the position of seeds in a pot and that can be easily mechanically planted while avoiding early drying of the pot.

[0004]

Means for Solving the Problems The technical means of the present invention taken to achieve the above object is that an upper slender pot is arranged in the vertical and horizontal directions of the pot seedling, and the upper slender pot has In a pot seedling production method using a pot sheet having an upper end portion of the pot formed with a seedling opening of the pot, a floor soil layer forming step of supplying floor soil to an inner space of the pot in the pot sheet, A seeding step of supplying seeds to the floor soil layer upper surface side near the seedling opening of the pot,
A soil covering layer forming step of covering the soil on the upper side of the floor soil layer, and a earth covering layer forming step of supplying earth between each of the pots on the pot sheet, and the floor soil supplying step,
This is done before the seeding step. The operation and effects are as follows.

[0005]

With the use of a pot sheet having an upper slender pot, the upper end of the upper slender pot is provided with a seedling opening capable of supplying floor soil and cover soil and sowing so that the floor soil can be supplied. By sowing later, as in the case of using the above-mentioned conventional pot sheet, the opening at the bottom large-diameter side is turned upward instead of the seedling opening side of the pot, and a large amount of floor soil is supplied after sowing. You don't have to do that.
In other words, at the time of sowing, a predetermined amount of bed soil is already supplied to each pot, and the seed is sown on the upper surface side of the filled bed soil. Instead, only the weight of the thin earth covering layer applied thereon acts. Therefore, it is possible to avoid inconveniences such as damaging the seeds due to a large amount of floor soil being thrown into the pot after sowing or shifting the seeding position of the seeds. In addition, since there is no need to reverse the pot sheet after sowing, there is a high possibility that the seed is damaged by compressing the floor soil in the seedling raising box for reversal after sowing, It is easy to avoid damaging the seeds and changing the seed position. In addition, by having a filling layer forming step of supplying filling material between the pots on the pot sheet, when planting pot seedlings,
The inconvenience of the pot seedling drying out early can be avoided.

[0006]

According to the present invention, when a pot seedling is prepared from the pot sheet having the upper thin pot, the seedling can be sown after supplying the soil by utilizing the seedling opening at the upper end of the pot. The seeds and their buds are damaged by the weight and the pressing force from the seedling box side when turning over, a large amount of floor soil is supplied on the seeds after sowing, and the seeds in the pot due to the impact when the sheet is turned over Avoid moving or
It is easy to be established at a predetermined position in a pot with high accuracy at a seedling raising rate with little damage to the seeds. In addition, since the pot seedlings are formed by supplying the soil between the pots on the pot sheet, the seedlings of the pot seedlings are unsuitable for mechanical planting due to early drying of the roots or warping when planting the pot seedlings. It is possible to create a pot seedling suitable for mechanical planting while avoiding a situation that is difficult to achieve.
