Abstract
The growth and yield of ever-bearing strawberry $(Fragaria{\times}ananassa\; Duch.)$ 'Pechika' were compared after transplant treatment in the raised hydroponic culture on highlands in summer season. The transplant production methods compared were whole plant refrigerated, outdoor over-wintered, pot-refrigerated, and 1 -year-old transplants. Growth increment at planting was the highest in pot-refrigerated transplants. C/N ratio of the pot-refrigerated transplants was 39.2 which was higher than 19.5 of 1-year-old transplants. However, the growth increment up to the first harvest were not different among the treatments. The first harvesting date of 1-year-old transplants was August 14, which was 5-9 days late than in the other treatments. The average fruit weight was highest in the 1-year-old transplants with 12.6 g. Marketable yield was the highest in the pot-refrigerated transplants, followed 1-year-old, plant refrigerated, and outdoor over-wintered transplants. Therefore, the pot-refrigerated transplants are recommended for marketable yield increase in ever-bearing strawberry cultured on highlands.
본 실험은 고랭지에서 사계성딸기의 고설벤치식 양액재배시 묘의 생산 및 저장방법에 따른 생육 및 수량을 비교하고자 실시하였다. 처리는 주냉장묘, 노지월동묘, 폿트냉장묘와 1년생묘였다. 정식시 묘의 생육량은 폿트냉장이 가장 많았다. C/N율은 1년생이 19.5로 가장 낮았고, 폿트냉장은 39.2로 가장 높았다. 그러나 첫 수확기의 생육량은 처리간에 큰 차이를 보이지 않았다. 1년생의 첫 수확시기는 다른 처리에 비해 $5\~9$일 늦었다. 1년생의 평균과중은 12.6g으로 가장 무거웠다. 상품수량은 폿트냉장이 가장 많았고, 1년생, 주냉장, 노지월동 순으로 많았다. 따라서 고랭지에서 단경기생산을 위한 사계성 딸기의 정식묘는 폿트냉장이 가장 좋았다.
