| 겨울철 오이 시설재배에서 태양열 시스템을 이용한 지중가온의 효과를 구명하고자 지중 40 cm에 15 mm의 PPC파이프를 130 cm이랑 에 4열 매설한 후 지중 20 cm의 지온을 $22~23^{circ}C$로 설정한 후 1996년 11월 7일부터 1997년 1월 30일까지 일정한 온도로 유지, 관리하여 무가온구와 가온구의 지상부, 지하부 및 수량을 비교시험한 결과는 다음과 같다 1) 지중가온에 의한 지온확보는 가온구는 15~20 cm에서 $22^{circ}C$ 정도의 평균온도를 확보할 수 있었고, 무가온구는 평균 $17~18^{circ}C$ 정도였다 2) 정식 30일 정도에서 초기생육은 가온구가 초장, 경경, 엽수, 엽면적 등 모두 증가하였으며 특히 초장 27%, 엽수 51%, 엽면적은 150% 정도 증가하였다. 또 지상부 평균 증가율도 관행대비 가온구 증가율이 117% 정도였다. 3) 가온구의 지하부 뿌리의 생장성이 관행구에 비하여 평균 56% 정도 증가하였다 4) 과수의 수량면에서도 총과수가 무가온구 313개, 가온구 614개로 가온구가 196% 정도 증수되었다. |

| Root zone temperature have influenced on protected cultivation in winter season. Especially root zone temperature is acted on limiting factor in crop cultivation. This study was conducted to obtain optimum temperature of root zone in Protected cultivation Root zone was warmed by heated water($28^{circ}C$) flowing through the PPC pipe(${phi}15$) buried depth 40 cm. And the flowing water was heated by solar system. Minimum air temperature during night time was set at $14^{circ}C$ and maximum air temperature during day time was set at $28~30^{circ}C$ the growing period of cucumber was from Nov. 6, 1996 to Jan. 30, 1997. The results are summarized as follows. 1. Average soil temperature at 15~20 cm depth was $22^{circ}C$ at warming plots, $17~18^{circ}C$ at non-warming plots 2. Early growth in leaf length, stem diameter, number of leaves and leaf area for 30 days after planting were accelerated by root zone warming. Especially, the grawing rate of soil warming plots was higher 27% in leaf length, 51% in leaf number, 150% in leaf area than non-warming Plots. Above-ground and underground part of warming plots was higher 117%, 56% than non-warming plots. 3. In total yield analysis, number of fruits were 614 in soil warming and 313 in non-warming plots. In the result, total yield of soil warming plots was increased with 196% than non-warming plots. 3. In total yield analysis. number of fruits were 614 in soil warming and 313 in non-warming plots. In the result. total yield of soil warming plots was increased with 196% than non-warming plots. |
