Abstract

This study was conducted to investigate the effect of anaerobic fermentation of wheat bran to prevent root-knot nematodes which are infected in plastic house due to over 10 years continuous cultivation of fruits and vegetables. Anaerobic fermentation treatment of wheat bran was done for 20 days by mixture of 2,000 kg fresh wheat bran per 10 are and soil with water in 30 cm soil depth. Chemical treatment of fosthiazate was done by mixture of 6 kg soil for 7 days. Both treatments show suppression of density of rootknot nematodes, especially in anaerobic fermentation treatment. Anaerobic fermentation treatment keeps the low level of root-knot nematode density until 90 days of cultivation and also showed good effect of melon growth. Related with death percentage of melon plant, anaerobic fermentation treatment shows only 3% and also large size of quality fruit but control 65%. Anaerobic fermentation treatment of wheat bran have proved to control the level of root-knot nematodes instead of synthetic chemicals for at least one cropping season and it showed good effect to fruit quality.

본 연구는 10년 이상 과채류를 재배하여 뿌리혹선충 피해가 많이 발생되었던 시설재배 토양에서 친환경적인 뿌리혹선충방제를 위하여 밀기울 토양환원처리 효과를 구명하였다. 토양소독처리후 뿌리혹선충의 밀도를 조사한 결과 시험전과 비교하여 모든 처리구에서 뿌리혹선충밀도가 감소하는 경향을 보였지만 특히 밀기울처리구에서는 높은 방제효과를 보였다. 처리후 90일경에도 밀기울처리구가 매우 낮게 유지되었으며 멜론의 생육도 가장 양호하였다. 수확기 멜론의 고사율을 조사한 결과 무처리구 65%인데 비해 밀기울처리구, 3%로 현저히 낮았으며 과실의 크기와 품질도 밀기울처리구가 우수하였다. 따라서 밀기울 토양환원처리는 뿌리혹선충 발생포장에 농약을 사용하지 않고 멜론을 1작기 동안 안전하게 재배할 수 있는 유망한 소독방법일 뿐만 아니라 멜론의 품질을 개선하는데 매우 효과적인 방법으로 생각되었다.
