地下水를 利用한 菜蔬育苗에 關한 硏究 = Studies on the Technique Utilizating Underground Water to Produce Vegetable Seedlings

다국어 초록 (Multilingual Abstract)

High temperature during a summer is one of important factors prohibting successful raising of vegetable seedlings. To study the possible method of reducing temperature, effects of temperatures (13℃, 18℃, 23℃, 28℃ and control) below the seedling pots on the seedling growth of several vegetables were examined. At the same time possible utilization of vinyl hose through which underground water of 13.5℃ was drained was test to determine the effects of air temperature, hose length and amount of water.
1.Seedling characteristics of warm season crops such as tomato, eggplant, red pepper, water melon and cucumber were best at 23℃ and were very poor at 13℃. Leaves were largest at high temperature of 28℃ while root growth was vigorous at 18℃.
2.Seedling growth of cool season crop, chinese cabbage, was best at 13℃ and tended to be better at lower temperature.
3.Amount of drained water as low as 15 liter per minute was enough when hose length was 200 meter. However, when air temperature exceeds 35℃, water amount should be increased up to 30 liter per minute when hose was 300 meter for cool season crops. Drained water should be increased to more than 30 liter per minute when hose length was 400 meter even for warm season crops.
4.With the hose of 400 meter and amount of drained water of 30 liter per minutes, grafted seedlings of water melon were successfully established as high as 100% and growth were also satisfactory.
