DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling-growing pot and a seedling-growing cell tray used for growing seedlings such as vegetables and flowers and trees. The present invention relates to a pot for raising seedlings and a cell tray for raising seedlings, in which a so-called looping phenomenon in which the roots extended in the pot are swirled and wound in a coil state is unlikely to occur, and even if the amount of cultivated soil that can be accommodated is small, drying of the double soil is unlikely to occur. Things.

[0002]

2. Description of the Related Art Conventionally, when growing vegetable seedlings or flowering seedlings, plastic seedling pots made of polyethylene or vinyl have been frequently used. Conventional seedling raising pots are commercially available as single seedling raising pot containers and seedling raising cell trays formed by connecting and connecting a large number of the single seedling raising pots. As shown in FIG. 9, most of the conventional seedling raising cell tray 30 has a cylindrical side wall 32 ending at an opening edge at an upper end side, and is continuous with an axial lower end side of the side wall 32, and has a central portion. A bottom wall 33 having a drain hole 34 (not shown), and the side wall 32 and the bottom wall 33 appropriately divide a relatively small cultivation storage chamber 31 having a cross-sectional shape into a plurality of pots 35 to form each pot. The upper end side of the side wall 32 of the body 35 is arranged in a plane along one plane and is connected and connected to a plurality of bodies.

Further, as shown in FIG. 10, storage pockets 41 are provided in a row in the horizontal and vertical directions, and a single soft pot 42 is inserted into the storage pockets 41, respectively. Seedling trays 40 are known.

[0004]

By the way, when growing vegetables or flowering seedlings, it is most important to maintain optimal air permeability in order to grow seedlings that are well-established and grow quickly. Conventional seedling pots have poor air permeability. Considering the air permeability of the medium (cultivation soil) for growing seedlings, reduce water to increase the supply of oxygen to promote mixing of materials and root development. I tried to ventilate. As a result, the roots of the seedlings elongate against the pot wall in search of oxygen due to the lack of oxygen during the cultivation, causing a so-called root winding phenomenon.
Generally, root-wrapped seedlings have less damage at the time of planting, but at present the growth after rooting is not necessarily good.
At the time of planting, it was necessary to remove the root winding.

[0005] When the conventional seedling raising cell tray 30 is used, or when the soft pot 42 is set in each of the storage pockets provided in the conventional seedling raising tray 40, the pot (cell) 35 is used. Since the upper open end edges of the soft pot 42 and the soft pot 42 are planarly arranged along one plane, even if it is intended to evenly water the pots 35 and the soft pot 42, the amount of water to be sprayed varies and the water is evenly sprayed. In particular, when the inner volume of the pot 35 and the soft pot 42 is small and the amount of cultivated soil that can be stuffed is small, the water retention of the cultivated soil is deteriorated, or the cultivated soil becomes extremely easy to dry. There was a problem that it was not possible to maintain an optimal growth environment for plants.

[0006] On the other hand, when the conventional seedling-raising cell tray 30 is used, a so-called transplanting operation of extracting the seedlings from the pots (cells) 35 and replanting them, or a so-called potting operation of replacing the extracted seedlings in a larger pot. In addition, not only is the work of picking and removing one seedling from each pot (cell) 35 one by one, but also the soil attached around the root at the time of transplanting is easily collapsed, and the transplanting operation is troublesome. In addition, the work time tends to be long, and the roots are damaged during these works, causing the plants to die.

When the conventional seedling raising tray 40 is used, when the transplanting or potting operation is performed, the soft pot 4 is used.
To pick and move the upper end of 2 one by one,
Due to the complexity of the transplanting operation, in addition to the inconvenience described above, water leached from the soft pot 42 or water sprinkled from the soft pot 42 accumulates in a gap formed between the storage pocket 41 and the soft pot 42. However, there is a problem that a mold grows at this position, root rot occurs, and a root turning phenomenon (called a circle phenomenon or a looping phenomenon) easily occurs in a soft pot.

As means for avoiding the above-mentioned lack of water in the pots, there is known a means in which a water absorption hole is formed in the bottom surface of each pot through the water absorption hole to absorb water from the bottom surface (for example, for example). JP-A-7-31288, etc.).
Also, there are known pots with various watering devices provided with a water storage tank for constantly supplying water (for example, Japanese Patent Application Laid-Open No. 9-2819).
No. 4 publication).

As a means for avoiding the above-mentioned root winding phenomenon in the pot, a seedling raising pot having slit-shaped holes formed in the side wall and the bottom wall is known (Japanese Utility Model Publication No. 4-87).
No. 52, Japanese Utility Model Laid-Open No. 5-43838).

The present invention has been devised in view of such circumstances, and a problem to be solved is to solve the above-mentioned problems and problems of the above-mentioned conventional seedling cultivation containers for raising seedlings. That is, the purpose is to be able to evenly and uniformly spray the amount of water sprinkled into each pot body, especially the pot body is relatively small and the amount of soil is small, Even if the water retention of the soil is poor, the soil can be prevented from drying, and the roots do not become tight during the soil cultivation and the root winding phenomenon does not occur. The present invention is to provide a seedling raising pot and a seedling raising cell tray.

Another object of the present invention is to provide a seedling for raising seedlings which has a simple structure and can be easily taken out without damaging the plants, and which can improve the efficiency of operations called transplanting and raising of plant seedlings. The purpose is to provide pots and cell trays for raising seedlings.
