Abstract

This study was carried out to elucidate the relationship between yields and inorganic nutrient contents, and then establish of critical range of inorganic nutrient contents in leaves of net melon in protected cultivation in Naju from 2004 to 2006. In considering the yields and nutrient contents of net melon, the critical ranges of macro-nutrient contents in leaves of net melon at 25 days after transplanting were in N 3.4~4.8%, P 0.4~0.7%, K 3.4~5.1%, Ca 2.7~4.1% and Mg 0.6~0.8%, respectably. The critical ranges of micronutrient content, such as Fe, Mn, Zn, Cu and B, were not found the regular trend with different growth stages. However, the critical range of micronutrient contents in leaves of net melon at 25 days after transplanting were in Fe 102~164, Mn 52~116, Zn 28~98, Cu 7~15 and B $36{\sim}72mg\;kg^{-1}$, respectably. Finally, these results might be used at the indicator for critical nutrient contents for diagnosis of nutritional disorder in net melon in protected cultivation.

시설재배 멜론에 대한 적정 양분함량 기준을 설정하기 위하여 2004년부터 2006년까지 나주에서 하우스 멜론의 수량 및 잎 중 무기양분함량을 조사하였다. 그 결과 3년간 조사한 멜론 재배 농가 포장을 대상으로 생육단계별 적정 양분함량 범위를 설정하였다. 멜론수량과 관련하여 생육단계별 잎 중 무기양분함량은 정식 후 25일이 가장 유의성 있는 상관을 보였으며 이 때 잎 중 다량원소 적정 범위는 N 3.4~4.8%, P 0.4~0.7%, K 3.4~5.1%, Ca 2.7~4.1%, Mg 0.6~0.8% 이었다. Fe, Mn, Zn, Cu 및 B 등의 미량원소 적정함량 범위는 Fe 102~164, Mn 52~116, Zn 28~98, Cu 7~15 및 B $36{\sim}72mg\;kg^{-1}$ 이었다. 여기에 제시한 멜론의 생육단계별 적정 양분함량 범위 기준은 농업현장에서 빈번히 발생하는 멜론의 영양장애를 해결하기위한 양분지표로 사용할 수 있을 것이다.
