For example, various pottery such as a round bowl, mountain grass pot, etc., pots made of unglazed pots (hereinafter referred to as "temporary pots") are put on the market together with an appropriate amount of soil, and they are also sown and raised. After germination, the seedlings were transplanted to soil. Alternatively, there is a temporary pot called a polypot which is made extremely thin from so-called vinyl resin or the like such as polyethylene, and seedlings are similarly transplanted to soil after germination. While such materials have the characteristics of being impervious to water, rusting, and not decaying, when transplanting seedlings into the soil, these pots, etc. in the soil must be removed by soil microorganisms unless the flowerpot or plastic pot is removed. This is because it is not decomposed and the root development is impaired. Therefore, when transplanting to soil, there are problems such as the need to take out the root stock from the temporary pot, the root cutting, and the rooting failure in new soil. In addition, considering the margin of the root stock from the temporary pot, it was sometimes transplanted to a large pot or planter. These also had similar problems during transplantation. In addition, the used plastic pots are incinerated and disposed of in the soil, but there was a problem in consideration for the environment due to problems such as generation of offensive odor gas and debris that will not be decomposed forever.

となっていた。FIG. 9 shows an example of the above poly pot. The outer diameter of the upper surface is about 50 to 150 mm, and the height is almost the same as the outer diameter. The thickness is generally about 0.2 to 0.4 mm. Soil such as culture soil is put in this and seeds are sown to raise seedlings. When the roots germinate and grow, they also pop out from the holes in the bottom. There is no room for the roots to grow from the side surface of the pot 1, and there is no escape route for the roots, so that a root migration phenomenon occurs in the pot 1. Further, in some cases, evaporation of water is limited, which causes a problem of root rot.

In this pot 1, since the roots can grow from the side surface and water can be evaporated, the defects such as root rot have been improved.

Since the bottom part was not uniform, it was easy to fall down and there was a difficulty in management. Moreover, since the material is an imported natural material mainly from the tropics, there is a problem that the material is difficult to obtain due to cost and resource problems.

用をする。[Operation] Water is poured into a pot for sowing and raising seedlings, and a soil such as a culture soil is added. Drill a hole around the center of the soil and sow seed. It is good that the soil rises. Sprinkle more water on it, but dry the medium slightly to about half, and germinate and root under indirect light. Avoid excessive humidity at the seedling raising stage, and use liquid fertilizer if necessary. When transplanting, seedlings are buried directly in the soil until the pot is hidden, and water is poured around them. There is concern that the roots may stop growing if they are exposed to direct sunlight or air, and that planting scratches may occur when the roots are taken out of the pot. However, these problems can be avoided because the pots are directly buried. After that, the pot is decomposed by soil bacteria, microorganisms and the like to be integrated with the soil and to further enhance the growth.

等に適合している。Such a pot 1 is made of a polymer having a particularly high biodegradability and needs to be suitable for sheet molding, film formation, injection molding and the like. A material that satisfies these requirements is formed into the shape shown in FIGS. Further, after forming into a sheet film, it was also possible to form the sheet film with a drawing die as shown in FIGS. These may be formed into a roll film by means of calendering or roll forming, and then formed into a drawing die in the same manner as shown in FIGS. 1 to 6. It has been found that an aliphatic polyester having high biodegradability is suitable as a material for the polymer in response to these demands. Aliphatic polyesters are biodegradable and relatively easy in terms of moldability, and
This is because at the decomposition stage, these constituent units are organic acids and fatty alcohols that are widely present in nature, and the safety of the decomposed products is expected. Furthermore, it is suitable for circulation in the biological world, which is environmentally friendly, such as being decomposed into carbon dioxide gas and water during decomposition.

比較を行った。In the present invention, experiments were carried out using two kinds of aliphatic polyesters having a melting point of 120 ° C. or less and a slightly higher temperature of 170 ° C. or higher. The former is an aliphatic polyester mainly synthesized from glycol and an aliphatic carboxylic acid (hereinafter referred to as material 1). This was used to form a pot 1 with an injection molding machine. Similarly, after forming into a sheet film, it was formed into a drawing die in FIG. The latter was formed in pot 1 using an injection molding machine in the same manner using lactic acid-based plastic (material 2). Similarly, biaxial stretching and, if necessary, laminating with coated paper are also possible, and after forming these sheet films, they were formed with a drawing die in FIG. A conventional pot was prepared and its performance was compared with that of the pot using the material of the present invention.

Excellent results were observed in terms of root cutting, transplantability of each pot directly into soil, degree of root and other planting damage, and prevention of pot overturn.

ことも確認された。[Table 2] Here, in injection molding, since the material 1 has a higher water absorption rate than general polyethylene or polypropylene as compared with the conventional material, it needs to be dried in advance. This can be done at 80 degrees Celsius for about 2 hours. The molding temperature was higher than 150 degrees. Material 2 was molded slightly higher than this. Furthermore, after molding, the process of biodegradation begins and decomposition in hot manure and wet soil accelerates, but depending on the conditions etc., in Material 2, it takes 3 to 6 months until disintegration and 6 to 12 before metabolization. It will be about a month. FIG. 7 shows the biodegradation characteristics of the materials 1 and 2 of the present invention, conventional coconut fiber, and Western paper used for copy paper. In the experiment, the sample was put into a commercial composite and the temperature was about 3
The degree of biodegradation was compared at 5 degrees. It was found to be biodegradable in about 3 to 6 months. FIG. 8 shows the state of seeding, seedling raising, seedling raising, transplantation, biodegradation, and humus using Salvia as a sample after seeding with the material 1 of the present invention, and biodegradation started at a fairly early stage after transplantation. It was approved to go. It is thought that humus as soil takes a long time, but biodegradation by soil microorganisms requires high humidity, high temperature,
It was also confirmed that good results can be expected because it is activated under conditions such as heated compost.

That is, since it is highly biodegradable, it can be directly transplanted in a pot, and at the seeding and seedling raising stages, it does not adversely affect the activation of microorganisms during biodegradation, is environmentally friendly, has a moderate water permeability and water absorption. Excellent in water resistance, water retention, breathability, liquid fertilizer use, shade of roots against sunlight, and blocking of roots from direct contact with the air. It is possible to expect good results such as easy watering. Furthermore, sowing that is not necessary to incinerate, sterility, proper maintenance of PH, shape retention of the pot itself, etc.,
The effect was recognized as a pot for raising seedlings. In addition to transplanting directly to soil, for example, when transplanting to a large pot or planter, transplanting can be performed in the pot.
