Abstract

This study was conducted to suggest an appropriate shading level for ‘Kuemsil’ strawberry during the summer nursery period by evaluating greenhouse environmental changes, transplant growth, post-transplant growth and yield under different shading levels. The experiment consisted of three treatments during the nursery period, based on 50% shading (S50), with additional shading nets applied to adjust the final shading levels to 55% (S55) and 60% (S60). Transplants were raised under the different shading levels for 40 days prior to transplanting, and subsequently cultivated for 142 days after transplanting. As a result, increasing shading levels reduced greenhouse temperature, but the daily average temperature at S60 exceeded 30°C on 23 of the 40 nursery days, indicating that high-temperature conditions occurred frequently. Under these conditions, petiole length was greater at higher shading levels, whereas leaf length, leaf width, and crown diameter were reduced in S55 and S60 compared to S50 at 40 days after treatment. In particular, the photosynthetic rate was significantly reduced in the S60. Regarding growth after transplanting, S55 exhibited similar growth to S50 from the early stages, whereas S60 required more than 60 days to reach a level comparable to the other treatments and showed delayed emergence and flowering of the first inflorescence by approximately 6－8 days. In terms of yield, there was no significant difference in average and total yield between S50 and S55; however, yield was significantly lower in the S60. In conclusion, these results suggest that shading levels should be maintained at or below 55% to promote healthy transplant growth and ensure stable post-transplant growth and yield of ‘Kuemsil’ strawberry during the summer nursery period.

본 연구는 ‘금실’ 딸기의 하절기 육묘 시 적절한 차광 수준을 제시하기 위해, 다양한 차광 수준에서 온실 환경 변화, 묘 생육, 그리고 이식 후 생육 및 수량을 평가하고자 수행되었다. 실험은 육묘 기간 동안 50% 차광(S50)을 기준으로, 차광망을 추가하여 최종 차광 수준을 55%(S55)와 60%(S60)로 조절한 3개 처리구로 구성하였다. 묘는 정식 전 40일간 다양한 차광 수준에서 육묘하였으며, 이후 정식하여 142일간 재배하였다. 연구 결과, 차광 수준이 증가할수록 온실 내부 온도는 감소하였으나, S60 처리에서는 육묘 기간 40일 중 23일에서 일평균 온도가 30℃를 초과하여 고온 조건이 빈번하게 나타났다. 이러한 조건에서 육묘기 동안 차광 수준이 증가할수록 엽병장은 신장한 반면, 처리 40일 차에 엽장, 엽폭 및 관부직경은 S50 처리 대비 S55와 S60 처리에서 감소하였다. 특히 S60 처리에서는 광합성 속도가 유의적으로 저하되었다. 정식 후 생육에서 S55 처리는 초기부터 S50 처리와 유사한 생육을 보였으나, S60 처리는 다른 처리와 비슷한 수준에 도달하는 데 60일 이상이 소요되었고 1화방 출현 및 개화가 6－8일 지연되었다. 수량 조사 결과, 평균 수량과 총 수량은 S50과 S55 처리 간에 유의미한 차이가 없었으나, S60 처리에서는 유의적으로 감소하였다. 결론적으로 하절기 ‘금실’ 딸기 육묘 시 건전한 묘 생육을 도모하고 정식 후 안정적인 생육과 수량 확보를 위해 차광 수준은 55% 이하로 유지해야 함을 시사한다.
