【 摘 要 】

A scrious loss of soil occurs during the transplanting of tea cuttings grown in bottomless paper pots. To minimize this, the effects of the application of sodium alginate solution to yellowish soil and the difrerent pot sizes (diameters of 4cm to 6cm) on the soil loss were examined. The prevention rate of soil in the smaller pots (4cm) was higher than in the larger pots (6cm). The optimal concentration and volume of sodium alginate solution for the prevention of soil loss was more than 0.3% and 80mL per pot (diameter of 6cm, length of 15cm), respectively. When the water was not added to the pots after the sodium alginate application, the high prevention rate more than 80% to 90% of soil was kept for about 10 days. Without the application of sodium alginate solution, the prevention rate or soil in the pots varied among the nine soil types. Sandy soil, a 4:6 mixture of yellowish red soil and peat moss, and a 4:6 mixture of yellowish red soil and rice husk charcoal showed the high prevention rates. The application of sodium alginate solution decreased the loss of soil regardless of soil type.
