| Research Abstract |
The root zone of cell seedlings were limited capacity of cell. Therefore The transplant proper time is shorten, it is easy to elongate, and aging. There is a fault that it is not easy to apply with big crops of crops and the seedling with a bad germination rate. The cell sheet method of raising seedlings of the no medium designed in this laboratory is handy and light weight.
Because moisture and liquid manure are always supplied in the cell sheet method, the faults of the above-mentioned cell seedling is canceled. Especially, the weight when transported, becomes about 1/2-1/3 of the cell trays. Moreover, taking root and the early growth of the drying condition in summer were extremely better, and higher than usual cell seedlings also that amount, even cell sheet seedlings had no medium and were imaged it was difficult that transplanting to the outdoors field This cell sheet : in putting to practical use. (1) It is not easy to break after it is necessary to put by one hole and seedlings

transplants though the cotton cloth and the pdyester unwoven cloth, etc. were used as upper protection to protect the rhizosphere. (2) Th peeling off of seedlings is easy in transportation. (3) It was necessary to supply phosphorus dividing to control algae of the rhizosphere and the generation of mold in the cell seedling, therefore usual hydroponics media could not used.
Surface of the cell sheet coated by a dry peat-moss, and the generation of algae and the mold of the rhizosphere was able to be controlled, and the problem of (1) and (3) was solved if surface of the cell sheet were shaded. (2) was solved by putting the size of the box and the cell sheet together from the cell tray more strictly when transported, and because changing the material of the sheet from 'Love Mat U' to 'Tetoron No200', root pasting with the sheet were improved. A suitable thing was not able to be found though the result of the above-mentioned was receivedr, cheap materials with equal to 'Tetoron No200' a performance were retrieved. However, materials have almost understood the influence is not exerted from the process in the growth of the plant. In the experiment in the Kyoto University Kyoto farm, cell sheet seedlings. The seedlings promoted in Kyoto University were sent to various places and grew under various field. Under hydroponics and bench, cell sheet seedlings grew better than cell tray sheedrings. Under other field, cell sheet seedlings grew little less than cell tray sheedrings. It seemed that the cell sheet had the possibility of practical use enough above. Less
