본 시험은 국내에 가장 많이 보급되어있는 북부하이부쉬 블루베리 '듀크' 품종에 대한 시설하우스 양액재배 가능성을 평가하기 위해 실시하였다. 블루베리 용기재배에 보편적으로 활용되는 피트모스(130L)와 펄라이트(40L) 배지를 180L 플라스틱 용기에 혼합하여 1년생 묘목을 심은 후 8년간 양액을 지속적으로 공급하는 양액처리구와 지하수만 공급하는 무처리구를 비교하였다. 양액은 NO3-N 4.6, NH4-N 3.4, PO4-P 3.3, K 3, Ca 4.6, Mg 2.2mmol-1를 EC 1.5로 조절하여 공급하였다. 양액처리구는 처리 후 8년차까지 수체 생장이 양호하였으며, 무처리구보다 주당 신초수가 18% 많고 주당 총신초장은 24%가 길었다. 양액처리구는 무처리구에 비해 뿌리 발달이 양호하였으며 주당 총건물중은 1.4배로 컸다. 식물체의 잎, 신초, 묵은 가지의 무기원소나 유기화합물이 양액처리구에서 대체로 높게 나타나 양액을 통한 양분흡수가 원활하였음을 확인되었다. 수량은 양액처리구에서 4년생 때부터 성과기에 달하여 시험이 종료될 때까지 높게 유지되었다. 이와 같은 결과로 양액재배기술은 블루베리 재배에 유용하게 활용 가능할 것으로 평가되었다.

The hydroponic culture for growing 'Duke' blueberry was evaluated in a protective greenhouse provided with similar environmental conditions to the conventional blueberry cultivations. One year old 'Duke' blueberry bushes planted in 180 L containers filled with 130 L peat moss and 40 L pearlite (v/v) were selected for the experiment. A nutrient solution consisted with NO3-N 4.6, NH4-N 3.4, PO4-P 3.3, K 3, Ca 4.6, and Mg 2.2 mmol-1 was supplied to the plants, comparing non-hydroponic treatment (provided with only underground water). Hydroponic culture increased number of shoot per bush by 18% and total shoot length by 24% compared with non-hydroponic culture. Total dry weight of a bush increased in the hydroponic with vigorous root growth 1.4-fold more than the non-hydroponic. Higher concentrations of inorganic elements and organic compounds were found in the hydroponic, indicating active nutrient absorption of the bush. The hydroponic produced high yield similar to adult bush from 4 years old age, maintaining the yield until 8 years old age. The findings of this study indicated that hydroponic cultivation systems will be useful for growing blueberry crop.
