DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to vessel or sheet for growing (hereinbelow, the term "grow" is used in a meaning such that it also includes the germination of a plant, and the growth thereof after the germination) a plant, a support for cultivating a plant, and an agent for modifying (or reforming) soil, which are suitably usable for tissue culturing or the germination of a seed and the growth thereof after the germination, and the growth of a plant in farm cultivation; and a method of growing (in the present specification, the term "growth" is used in a meaning such that it also includes germination and growth after the germination) a plant, while using a gel-like support substantially as it is which has been used in the artificial culturing, whereby a plant can be cultivated in an environment wherein aeration or ventilation is not restricted (e.g., in farm cultivation).
More specifically, the present invention relates to a vessel or sheet for growing a plant (hereinbelow, this term is used in a meaning such that it also includes "seed"), which enables easy transfer of the plant, the promotion of the germination or growth of the plant, and marked reduction in the necessity for strict control of water, etc.; of the plant; and a soil-modifying agent for supporting or carrying a plant in the cultivation of the plant in combination with another plant-supporting carrier (such as soil), whereby the physical, chemical and microbiological properties of the carrier can be improved or modified on the basis of the application of such a soil-modifying agent to another carrier such as soil); and the culturing to cultivation thereof; and particularly, a method of continuously growing a plant wherein at the time of the transfer from the culturing thereof in a vessel into farm cultivation thereof, the support (or planting material) which has been used in the culturing of the plant can also be used as it is in the cultivation thereof, thereby to omit or simplify the transferring step for the plant, to prevent the physical damage to the root thereof, and to enable the smooth growth of the plant after the transfer thereof into the cultivation step.
In the present specification, "culture" (or culturing) of a plant refers to the growth or multiplication of the plant under a condition (mainly in a vessel) such that the aeration or ventilation into the plant-growing system is controlled or limited; and "cultivation" of a plant refers to the growth or multiplication of the plant under a condition (mainly in a greenhouse or open-air field) such that the aeration or ventilation into the plant-growing system is not limited. With respect to such definition of the culture, it is possible to refer to "Technique in Plant Tissue Culturing" edited by Takeuchi et al., Page 1 (1983), Asakura Shoten; and "Iwanami Biological Dictionary" (3rd edition) edited by Yamada et al., Page 1006 (1983), Iwanami Shoten.
BACKGROUND ART
In recent years, it has attracted much attention to develop a technique for growing or regenerating a plant having a character or trait suitable for an intended purpose. Among these growing and regenerating techniques, a plant tissue culture technique, i.e., a technique wherein a part of a plant is separated from the main body thereof, and is grown in the inside a culturing vessel has particularly attracted much attention, since it enables the mass multiplication of a genetically identical clone in a short period of time (Kiyoshi Okawa "General Introduction to Horticultural of Flowers", page 54, 1995, Yokendo).
Heretofore, in the production of a plant (mainly, a plantlet) using a plant tissue-culturing technique, agar gel has been used as a support therefor. However, the agar gel has a characteristic such that it hardly absorb water content again, after it discharges water content due to the evaporation of water or the absorption of water into the plant. Particularly, in an open-system cultivation environment such as farm cultivation, the water content-retaining function of the agar and the plant-retaini
