Abstract
팽연왕겨(ERH)가 혼합된 상토를 이용하여 '설향' 딸기를 육묘하면서 용기 내 수분보유 특성, 그리고 모주 및 자묘의 생장에 미치는 영향을 구명하고자 본 연구를 수행하였다. 용기용수량 상태의 수분 함량은 팽연왕겨가 20-23% 범위로 딸기전용상토 60-66%, 양질사토 30-35% 및 마사토 30-34%와 비교할 때 매우 낮았다. 수분 함량은 관수 8시간 후에 10-12%로 급격히 낮아졌으며 연결포트의 각 셀당 수분편차가 크게 나타났다. ERH와 코이어 더스트(CD), 사양토(SL), 펄라이트(PL) 그리고 마사토(SMM)의 4종류 물질을 혼합하여 조제한 모든 상토는 pH 6.7-7.1, EC $0.03-0.08dS{\cdot}m^{-1}$ 범위로 측정되었고, 관수 20일과 40일 후에 뚜렷한 차이를 보이지 않았다. 자묘의 생육은 혼합상토 중 ERH + SL(55:45, v/v)에서 가장 우수하였다. ERH + CD 상토의 경우 CD의 혼합비율이 30% 이상일 때 생육이 저조한 경향을 보였고, ERH + PE는 혼합 상토 중 지상부와 근권부 생육이 가장 저조하였다. 팽연왕겨가 혼합된 상토에 정식한 모주의 생육은 정식 30일 후 ERH + PE와 ERH + CD 모두 PE + CD(50:50, v/v) 상토보다 저조하였다. 모주정식 90일 후의 생육은 ERH + CD 상토는 CD의 혼합 비율이 높을수록 생육이 우수하였지만 정식 30일 후와 유사한 경향을 보였고, PE + CD(50:50, v/v)보다 저조하였다. 본 연구결과는 팽연왕겨를 포함한 혼합상토 조성과 이를 이용한 육묘과정의 수분 관리에 관한 기초자료로 활용될 수 있을 것으로 기대된다. This research was conducted to investigate the changes in moisture retention capacities of expanded rice-hull (ERH)-based root media and their influences on the growth of mother and daughter plants in vegetative propagation of 'Seolhyang' strawberry. The proportion of water at the container capacity of ERH medium was in the range of 20 to 23%. This range was lower than the 60 to 66% of strawberry-specialized medium, the 30 to 34% of soil mother material (SMM) and the 30 to 35% of loamy sand. The moisture content of ERH was reduced to 10 to 12% at 8 hours after irrigation, and there were large variations among replications of ERH medium. Among four kinds of root media formulated to contain ERH, the medium of ERH + coir dust (CD) (55 + 45%, v/v) had 26.5 and 32.5% water contents at 20 and 40 days after irrigation to daughter plants, respectively. The m edia o f ERH + sandy loam (S L) and E RH + S MM showed similar trends i n moisture r etention. The pH and EC i n the all root media tested were in the range of 6.7 to 7.1 and 0.03 to $0.08dS{\cdot}m^{-1}$, respectively. The pHs and ECs measured at 20 and 40 days after irrigation were not significantly different in each root medium. Among the root media formulated to contain ERH, the growth of daughter plants was the highest in the treatment of ERH + SL (55 + 45%, v/v). As the blending rate of coir dust was elevated in the ERH + CD media, moisture retention capacity increased gradually, but the growth of daughter plants became worse even though the medium showed higher moisture retention capacity than other root media tested. The growth of roots and aboveground tissues of daughter plants deteriorated in the root media formulated by blending ERH + perlite (PE) at various ratios. The results of this research suggest the optimum formulations of root media and management of moisture content in raising of strawberry daughter plants when ERH is a component of root media.
