Abstract

In this study, the effect of crown heating on the cultivation environment, budding, flowering and yields of strawberry was analyzed. In December, January, and February, when the outside temperature was low, the average strawberry crown temperature at daytime in the test zone was 1.3°C higher than that in the control zone, and the average strawberry crown temperature at nighttime in the test zone was 2.7°C higher than that in the control zone. The average bed temperature at daytime in test zone was 1.7°C higher than that in the control zone, and the average bed temperature at nighttime in test zone was 2.4°C higher than that in the control zone. As a result of performing correlation analysis and regression analysis on strawberry crown temperature and budding period, the correlation coefficient was -0.86, which tended to be shorter as the crown temperature was higher, and the determination coefficient was 0.74. The total yields of strawberry during test period were 392.6 g/plant for test greenhouse and 346.0 g/plant for control greenhouse respectively. As for the quality of strawberries, the ratio of 2L (very large) grades and L (large) grades was 62.4% in the test greenhouse and 58.5% in the control greenhouse, indicating that the proportion of high quality strawberries was higher in the test greenhouse.

본 연구에서는 한 온실 내에서 딸기 재배 베드를 관부 난방 적용 베드, 관행 베드 2처리로 나누고 동일 환경에서 관부 난방이 딸기 재배 환경, 출뢰, 개화 및 수확량에 미치는 영향을 분석하였다. 관부 난방 전 두 처리에서 딸기 관부 온도 및 배지 온도는 큰 차이 없었으며, 외기온이 낮은 12월, 1월, 2월에는 시험구의 주간 평균 딸기 관부 온도는 대조구에 비해 1.3℃ 높았으며, 야간 평균 딸기 관부 온도는 대조구에 비해 2.7℃ 높게 나타났다. 주간 배지 온도는 시험구가 대조구보다 평균 1.7℃ 높았으며, 야간 배지 온도는 시험구가 대조구보다 평균 2.4℃ 높게 나타났다. 딸기 관부 온도와 출뢰 기간에 대한 상관분석 및 회귀분석을 수행한 결과 상관계수는 –0.86으로 높은 음의 상관관계를 보여 관부 온도가 높을수록 출뢰 기간이 짧아지는 경향이 있었으며, 결정계수는 0.74로 높은 설명력을 보였다. 딸기 화아분화는 10－20℃에서 촉진되고, 5－10℃, 25－30℃에서는 효과가 없으며, 5℃ 이하 및 30℃ 이상일 때는 저해되는데, 대조구 온실이 외기온이 낮은 12월, 1월, 2월에, 특히 야간의 딸기 관부 온도가 월별로 각각 7.3℃, 7.6℃, 8.8℃로 나타나 10℃ 이하로 유지되면서 화아분화가 촉진되지 않았고, 시험구에 비해 출뢰, 개화가 늦은 것으로 판단된다. 3월 말까지의 딸기 수확량은 시험구 392.6g/plant, 대조구 346.0g/plant로 관부 온돡 높았던 시험구에서 약 13.5% 높게 나타났으며, 딸기의 품질은 2L 등급과 L 등급의 비율이 시험구 62.4%, 대조구 58.5%로 시험구에서 높은 등급의 딸기 비율이 더 많은 것으로 나타났다. 딸기의 화아분화의 주요인은 온도이고, 2차적 요인은 일장이므로 추후 연구를 통해 관부 온도뿐만 아니라 일장 등 다양한 요소를 고려하여 딸기 생육, 수확량의 변화를 분석해보는 연구도 필요하다고 판단된다.
