초록
본 연구는 유기액비 관비가 ‘녹광(세미니스)’ 고추의 생육과 수량에 미치는 영향을 구명코자 실시하였다. 유기액비 조성에 따라 대조구(화학비료시비), 유기액비 Ⅰ(계분 : 어분 : 대두박, 2:1:1), 유기액비 Ⅱ(계분 : 골분 : 대두박, 2:1:1), 유기액비 Ⅲ(계분 : 골분, 1:1), 유기액비 Ⅳ(계분 : 쌀겨 : 대두박, 2:1:1) 등 5처리를 두었다. 유기액비 조성재료와 비율에 따른 액비의 pH와 EC는 각각 6.5~6.8와, 2.91~3.69dS·m-1의 분포를 나타냈다. 유기액비 조성 비율에 따른 C/N율은 유기액비 Ⅳ가 5.75로 가장 높았으며, 그 외 처리는 처리간에 차이가 없었다. 주당 총과중은 유기액비 Ⅳ 처리구에서 1,558g으로 가장 무거웠으며 총과수는 대조구에 비해 23.7% 증가하였다. 홍고추의 캡사이신 함량은 유기액비 Ⅰ과 Ⅱ에서 대조구에 비하여 증가하였으며, 유기액비 Ⅲ과 Ⅳ 관비구에서는 감소하였다. 당도는 유기액비 Ⅳ 관비구에서 10.0°Brix로 가장 높았다.
Abstract
The present study was carried out to evaluate the effects of organic liquid fertilizer (OLFs) fertigation on the growth and fruit quality of hot pepper (Capsicum annuum L.) cv. ‘Nokkwang (Seminis Korea)’. Treatments were given with control (chemical feritilzer), OLF Ⅰ(fowl dropping:fish meal:soybean meal, 2:1:1), OLF Ⅱ(fowl dropping:bone meal:soybean meal, 2:1:1), OLF Ⅲ(fowl dropping:bone meal, 1:1), and OLF Ⅳ(fowl dropping:rice bran:soybean meal, 2:1:1). The composition ratio of OLF based on weight to weight. The pH and EC of OLFs according to different material and compositions ranged from 6.5 to 6.8, and from 2.91 to 3.69dS·m-1, respectively. The C/N ratio was the highest as 5.75 in OLF Ⅳ, and there was no difference among the treatments in C/N ratio of the exception of OLF Ⅳ. In OLF Ⅳ total fruit weight was the highest as 1,558g per plant and total fruit number increased as 23.7% compared to control. The content of capsaicin in the ripened pepper increased with OLF Ⅰ and Ⅱ treatments, and decreased with OLF Ⅲ and Ⅳ treatments compared to control of 662mgㆍkg-1, but the soluble solid content was the highest with OLF Ⅳ treatment as 10.0°Brix.
