Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising container for raising fruit and vegetable seedlings.

[0002]

2. Description of the Related Art In order to grow seedlings of fruits such as strawberries and vegetables such as eggplant, various containers for raising seedlings have been conventionally used. For example, as a container for raising seedlings suitable for raising seedlings of strawberries. A container for raising seedlings as shown in Fig. 6 is widely used.

The seedling-growing container 3 shown in FIG. 6 has a cylindrical shape in which the main body 31 has a circular cross-sectional shape, the length is 2.5 times or more the diameter of the circular shape, and the internal volume is 100 to 200 cm ^3. It is made of molded synthetic resin, and a taper taper is formed in the longitudinal direction of the main body 31, a flange 32 protruding outward is formed at the upper end, and a bottom plate at the lower end is formed as shown in FIG. The hole 33 as shown in FIG. This hole 3
No. 3 does not drop the soil in the main body 31, and
It is formed so that the roots grown in the main body 31 can extend outside the container. According to this container 3 for raising seedlings, less soil is required for raising seedlings, good root growth,
In addition, there is an advantage that workability of planting and survival after planting are good, and storage and transportation are efficient.

[0004]

When the above-mentioned seedling-growing container 3 is used for strawberry cultivation, the seedling-growing container 3 is filled with soil and grown with the runners from the parent plant in contact with the leaves.
The runners are separated when about one sheet is printed, and then the
As shown in (a) of FIG. 8, with the auxiliary tool 4 for watering and fertilizing attached to the upper end of the container 3 for raising seedlings, it is locked to the frame 51 of the holding device 5 as shown in (b) of FIG. And raise the seedlings.

In the process of growing the seedlings in the seedling-growing container 3, the roots straightly extend downward in the main body 31 of the tubular body, and the roots grow without being entangled with each other. The planting is carried out when the seedlings are grown to a predetermined size.

As a method for planting seedlings, there are a method of taking out the seedlings from the seedling raising container 3 and planting only the seedlings, and a method of planting the seedling raising container 3 without taking out the seedlings. The method of taking out the seedlings and planting them takes time and effort, but
Subsequent growth of seedlings will be good. The method of planting the whole seedling raising container 3 is simple in planting work, but since the root outlet of the grown seedling is only the hole 33 at the lower end of the seedling raising container 3, the growth of the seedling after planting is carried out for the raising seedling. It is inevitable that the seedlings will be worse than if they were taken out from the container 3 and planted.

It is an object of the present invention to provide a container for raising seedlings which allows good growth of the seedlings after planting even when the seedlings after planting are planted together without removing them from the container.

[0008]

[Means for Solving the Problems] A container for raising seedlings according to the present invention for achieving the above object comprises a plurality of containers which are connected to the lower peripheral wall of a cylindrical body having a tapered taper from inside to outside of the cylindrical body. Is a container for growing seedlings, which comprises a main container made of synthetic resin having an opening formed therein, and a sub-container made of synthetic resin having a bottom and formed to cover the area where the opening is formed in the main container.

The cylindrical body having a tapered taper of the main container preferably has a circular cross-sectional shape from the viewpoint of handling of the container itself and easiness of manufacturing, but other shapes such as an elliptical shape, It may be a quadrangle, a semicircle, or the like. The taper may form a uniform taper in the length direction, or may form a different taper in the length direction. The lower end of the tubular body is an open end or a perforated bottom plate so that grown roots can easily come out.

The opening of the lower peripheral wall of the tubular body is such that after growing seedlings are planted together with the main vessel without taking out the seedlings, the grown roots come out from the open end or the hole at the lower end of the tubular body and soil. It is formed so as to extend inward and extend from the opening of the lower peripheral wall to extend into the soil. The slit-shaped, zigzag-shaped, and mesh-shaped openings are formed substantially evenly around the entire circumference of the lower peripheral wall.

The sub-container is used by being attached to the lower part of the main container during seedling raising, that is, until planting. Since the lower end of the cylindrical body that is the main container is an open end or a perforated bottom plate, and openings are formed in the lower peripheral wall, irrigation of the main container leaks out from these openings, and cultivated soil drops out. To prevent this, attach a sub-container to the main container during seedling raising. When planting, remove the sub container from the main container and plant the seedlings together with the main container. The shape of the sub-container is formed so as to cover the lower end of the tubular body and the area of the opening of the lower peripheral wall in conformity with the shape of the lower portion of the tubular body of the main vessel.

Here, in order to prevent the sub-container from slipping out of the main container when the sub-container is attached to the main container, a concave portion or a convex portion is formed on the inner surface of the sub-container, and the sub-container is formed on the outer surface of the main container. The convex portion or the concave portion can be formed at a position corresponding to the concave portion or the convex portion on the inner surface of the container.

[0013]

The container for raising seedlings of the present invention comprises a main container having an opening formed in the lower peripheral wall of a tubular body, and a bottomed sub-container formed so as to cover the area where the opening of the main container is formed. Thus, by mounting the sub-container on the main container during use, it can be used in the same manner as a conventional container for raising seedlings. At this time, by forming the concave and convex portions that are fitted to each other in the main container and the sub container, the main container and the sub container are elastically deformed to each other so that the concave portion and the convex portion are fitted to each other, and the sub container is prevented from falling off. To be done.

Even when the whole main container is planted, an opening is formed in the lower peripheral wall in addition to the open end at the lower end or the hole in the bottom plate in the main container. It goes into the soil and promotes root growth.
