사계성 ‘페치카’ 딸기의 고랭지 여름철 양액재배시 배지선택

국문 초록 (Abstract)

사철딸기 ‘페치카’ 품종의 고설벤취 양액재배에 의한 고랭지 여름생산(6월-9)월)에 적합한 배지를 선발코자 본 실험을 수행하였다.
재배기간 중 시설 내 상온은 최고온도는 33~34℃였고 최저온도는 2003년에는 16℃, 2004년은 4.9℃로 연차가 변이가 심하였다. 배지의 불리성에서 비중은 펄라이트가, 용수량은 입상암면 +피트모스가 다른 배지에 비해 높았고 처리별 근권온도는 입상암면과 피트모스 혼합배지가 최고온도 25.5℃, 최저온도 18℃로 가장 낮았으며, 펄라이트와 피트모스 혼합배지, 왕겨와 피트모스 혼합배지, 펄라이트 순으로 낮았다. 입상암면과 피트모스 혼합배지가 펄라이트 단용배지 보다 주간에 최고 3℃, 야간에 최저 1℃ 정도 낮았다. 배지에 따른 초기생육(엽수, 엽장, 엽폭, 생체중)은 펄라이트 단용배지에서 가장 억제되었으며 다른 배지간에는 차이가 없었다. 총수량은 펄라이트와 피트모스 혼합배지에서 연평균 1,632㎏/10a로 다른 처리에 비해 가장 높았지만 2003년에 3,013㎏/10a, 2004년에는 732㎏/10a로 연차간 변이가 심한 경향이었고 과실의 가용성 고형물 함량은 모든 처리에서 9.5~10%로 처리간 차이가 없었다.
따라서 여름 고온기 딸기 양액재배를 위한 적정배지는 과실품질은 비슷하면서 수량이 높은 펄라이트와 피트모스 혼합배지가 적정하다고 판단된다.

This experiment was conducted to investigate the optimal media for ‘Pechika’ ever-bearing strawberry grown in hydroponic culture system in summer highland. Three mixed media (I : 1, v/v) of peatmoss with perlite, rice hull, and granular rockwool, and four solution strengths of EC 0.5, 0.75, 1.0 and 1.25 dSㆍm­¹ were tested. Root zone temperature in peatmoss + perlite media was 1 to 3℃ lower than in the other media. The culture medium of mixing to peat moss and perlite was most effective in producing good yield and fruit quality. The culture medium of mixing to peat moss and perlite was the highest about 1,632 ㎏/10a to yield yearly average, but was very undulating 732 ㎏/10a to yield in 2004 year and 3,013 ㎏/10a in 2003 year. The deformed fruits were increased when the solution strength was increased, especially in EC 1.25 dSㆍm­¹. The soluble solids and the acidity content of fruits were increased with higher solution strength regardless of media. The uptake of Ca and Mg was inhibited at higher solution strength, and the uptake of N, P and K was promoted. Therefore, the culture medium of mixing to peat moss and perlite was the most suitable culture medium to product strawberry in summer, because it had the highest yield even though fruit quality among treatments was not significant.
