Abstract

This study was carried out to investigate damp injury caused by tomato coir bag culture and prevent that. The tomato variety was used 'Minichal', and tomatoes were grown in greenhouse. The nutrient solution based on Yamazaki Tomato Standard Solution was irrigated from one hour after sunrise to two hour before sunset. The slits for darainage were made in three types; I, L, and bottom slit type. The coir bag of I and L type had six slits of 15cm length, that of bottom slit type had three slits of 15 cm length. The weight of coir bag in 24 hours after saturation was 14.2 kg in I type, 13.8 kg in L type, and 12.8 kg in bottom slit type, but there was not significant difference. The weight of coir bag after one day irrigation was 14.5 kg, 14.2 kg, and 13.3 kg at L, I, and bottm slit type, respectively. This means that the moisture content of coir bag during cultivation was lowest in bottom slit type. The number of adventitious root on stem was 160, 170, and 53 at I, L, and bottom slit type, respectively. The dry weight of root and root length were highest at bottom slit type, compared to other treatment. The marketable yield was highest 26.5 kg/20 plant in bottom slit type. For increasing yield and preventing damp injury, bottom slit type was most effective at U type bed coir bag culture.

본 연구는 토마토 코이어 자루재배시 습해의 원인을 구명하고 습해를 방지하기 위하여 실시하였다. 실험은 미니찰을 고시하고 단동형 2중 플라스틱하우스에서 실시되었다. 배양액은 Yamazaki 토마토 전용배양액을 사용하였으며, 배양액 공급시간은 해뜨고 1시간 후 시작하여 해지기 2시간 전에 종료하였다. 자루당 I자형 찢기 및 L자형 찢기는 6개씩 15cm 길이로 찢었으며, 밑 찢기는 3개씩 15cm 길이로 뚫었다. 배액구 위치에 따른 배지무게는 포습 24시간 후 I자형 찢기는 14.2kg, L자형 찢기는 13.8kg, 밑 찢기는 12.8kg로 밑 찢기가 가장 가벼웠다. 포습 24시간 후 1일 관수하여 무게를 측정한 결과 I자형 찢기는 14.5kg, L자형 찢기 14.2kg, 밑 찢기 13.3kg로 역시 밑 찢기가 가벼웠다. 이것은 밑 찢기에서 배지내 함수량이 가장 적은 것을 의미한다. 부정근 발생정도는 I자형 뚫기 및 L자형 뚫기에서 160 및 170개 발생하였으나 밑 뚫기에서는 53개 발생하였다. 뿌리의 건물중(5주)은 밑 찢기가 57g으로 I자형 찢기 23g 및 L자형 찢기 25g과 비교해서 2배 이상 높았으며, 뿌리길이도 밑 찢기가 31.4cm로 다른 찢기 방법과 비교하여 길었다. 상품수량은 밑 찢기가 26.5kg/20주 로 I자형 찢기 19.7kg, L자형 찢기 24.0kg와 비교해 높은 수량성을 보였다. 따라서 U자형 베드에서 코이어 자루배지를 이용하여 수경재배를 할 경우 배액구는 밑 찢기로 만들어야 습해를 방지하여 생산성을 높일 수 있을 것으로 사료되었다.
