This study aimed to investigate the nutrient solution developed by based on nutrient-water absorption rate of strawberry 'Maehyang' by comparing growth and yield for 8 months with 5 kinds of nutrient solution with different ion composition. Strawberry plants were planted at elevated bed and supplied...

매향의 특징은 무엇인가? | 8%로 매우 낮다. 딸기 주요 수출 품종인 ‘매향’의 주요특성은 화방 당 화서가 10~15개 정도이며, 당도가 높고 산도가 낮으며, 경도가 우수하여 저장성이 좋은 특징을 갖고 있다(Kim 등, 2004). | |
국내 개발된 배양액은 무엇이 있는가? | 특히 수경재배는 뿌리를 통한 양수분 흡수가 잘 이루어지도록 근권 환경을 조절하여 재배하는 특성을 갖고 있으며, 재배시기, 생육단계 뿐 아니라 작물의 품종, 배지 및 원수의 특성 등이 작물 생육에 영향을 줄 수 있다. 국내에서는 주요 원예작물을 중심으로 재배 시스템, 배지 특성을 고려하여 과채류 배지경 배양액(Kim, 1998), 토마토(Choi 등, 1998; Yu와 Bae, 2005), 파프리카(Choi 등, 2001), 허브(Yeo and Lee, 2004), 감자(Chang 등, 2000) 등의 배양액이 이미 개발되었다. | |
주당 과수 증가로 식물체에 착과수가 많아지면 어떤 결과가 나타나는가? | 4% 를 차지하였다. 한편 과다 착과로 양분소모가 많아지면, 즉 식물체 수용부위 활성이 높은 과실이 많을수록 잎이나 뿌리로 분배되는 동화산물이 줄어들어 결과적으로는 과실생장에 나쁜 영향을 미칠 수 있다(Lee와 Cha, 2009). Lee 등(2014b)은 주당 착과수가 많을수록 총 과실 수량은 증가하나 상품과수가 감소하고, 당도가 감소한다고 보고하여 착과량 조절이 상품수량에 매우 중요하다고 하였다. |
