Abstract

PROBLEM TO BE SOLVED: To provide a container for raising a cell molded seedling and the raising method of the cell molded seedling capable of uniformly taking out and transplanting the seedling. SOLUTION: For this container for raising the cell molded seedling, the container 3 composed of bio-degradable plastic to be degraded in soil is freely attachably and detachably mounted to the cell tray plug 2 of a cell tray 1 composed of normal plastic such as polypropylene or vinyl or the like. For this raising method of the cell molded seedling, using soil 4 is put in the container, a seed 5 is sown, and after the seed 5 sprouts and grows to the transplantable seedling 6, the seedling 6 is taken out from the cell tray plug 4 along with the container 3 and transplanted to a planting bed 7 for each container 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for growing cell seedlings and a method of raising cell seedlings.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 1, a cell tray plug 2 of a cell tray 1 made of ordinary plastic such as polypropylene, vinyl or the like, as shown in FIG.
The seed medium 5 is sowed directly, the seeds 5 are sown, and the seeds 5 germinate and grow into transplantable seedlings 6. Then, the seedlings 6 are directly taken out from the cell tray plug 2 by a worker using a hand or a spatula. I was For example, a farmer specializing in raising seedlings of flowers such as Turkish bellflower and begonia usually raises hundreds of thousands of cell-molded seedlings. (1) It is necessary to transplant the seedlings 6 at a stretch in a limited optimal period, but since the seedlings 6 are manually removed from the cell tray plug 2, it takes time, and a large number of workers are needed in a short term. Needs to be put in, and this puts pressure on the business. (2) When removing the seedling 6 from the cell tray plug 2,
As shown in FIG. 6, it does not grow even if it is bent or transplanted due to root cutting or the like. (3) To remove the seedling 6 from the cell tray plug 2,
It's a simple task, it takes time, is shunned by young people, and can't foster successors.

DISCLOSURE OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, and it is an object of the present invention to provide a cell-molded seedling raising seedling container and a cell-molded seedling capable of uniformly removing and transplanting seedlings. The purpose of the present invention is to provide a seedling raising method.

[0004]

Means for Solving the Problems The container for cell-molded seedling raising of the present invention is configured such that a container made of biodegradable plastic that decomposes in soil is detachably attached to a cell tray plug of a cell tray made of ordinary plastic such as polypropylene or vinyl. It is characterized by being worn.

[0005] The method for raising seedlings of the present invention is to put soil into a container made of a biodegradable plastic detachably attached to a cell tray plug of a cell tray made of a normal plastic, sow seeds, and germinate and transplant the seeds. After growing into a possible seedling, the seedling is taken out from the cell tray plug together with the container made of the biodegradable plastic, and transplanted into a planting bed with the container made of the biodegradable plastic. .

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a container for cell-molded seedling raising of the present invention will be described with reference to the drawings. In FIGS. In the cell tray, a large number of cell tray plugs 2 having a shape such as a circle and a corner are provided vertically and horizontally. FIG. 2 is a partial cross-sectional view of the cell tray 1. A lactic acid-based biodegradable plastic made from natural agricultural products such as corn, potato, sugar cane, rice, sugar beet is injected into a cell tray plug 2 of the cell tray 1 by an injection molding machine or the like. As shown in FIG. 2, the container 3 molded as described above is detachably mounted so that the upper edge 8 of the container 3 protrudes from the surface of the cell tray 1 by an appropriate length t. The protruding length t is not particularly limited as long as it is easy for the worker to grasp the edge of the container 3 and pull out the container 3 from the cell tray plug 2. It is. The shape of the container 3 is as follows.
It is natural that the cell tray 1 is molded so as to conform to the shape of the cell tray plug 2.

Next, an embodiment of the method for raising seedlings of cell-molded seedlings of the present invention will be described with reference to the drawings.
As shown in the figure, a soil 4 is put into a container 3 made of the biodegradable plastic, which is detachably attached to a cell tray plug 2 of a cell tray 1 made of ordinary plastic such as polypropylene or vinyl, and a seed 5 is sown. After germinating and growing into a transplantable seedling 6 as shown in FIG. 3, the seedling 6 is taken out of the cell tray plug 2 together with the container 3 and, as shown in FIG. It is implanted every time.

[0008]

EXAMPLE A soil 4 is placed in a container 3 made of lactic acid-based biodegradable plastic having a diameter of about 2 cm and a height of about 5 cm which is detachably attached to a cell tray plug 2 of a cell tray 1 and sowed and transplanted with Turkish bellflower seeds. After growing into a young seedling 6,
As a result of inserting the container 3 into the planting bed 7 and transplanting it, the container 3 decomposed from the wall in about 2 to 3 weeks, and the roots of the seedlings 6 grew vigorously into the planting bed 7, which is inferior to the conventional one. Experiments have confirmed that no flowers bloom. In this case, the efficiency of removing the seedlings 6 from the cell tray plug 2 was about 10 times higher than the efficiency of the conventional removing operation using a spatula or the like. Moreover, seedling 6
Of course, there is no damage such as root breakage. In addition, since the work of inserting the seedlings 6 into the planting bed 7 can be performed uniformly without any special technique, even a beginner can perform the same work amount as an expert.

[0009]

As described above, the present invention has the following advantages. (1) Since the work of removing seedlings from the cell tray plug of the cell tray can be performed uniformly and in a short time, labor saving and labor reduction can be achieved. (2) Since transplantation to a plant bed can be performed uniformly, mechanical planting can be performed in the same manner as mechanical planting of rice seedlings. (3) Problems such as root breakage of seedlings unlike conventional cases do not occur.
