Abstract

To determine the effect of winter green manure crops for tillage and no-tillage organic pepper cultivation in plastic film house, five different green manure crops were cultivated during winter season. In nutrition composition of green manure crops, total nitrogen contents were higher in Vicia hirsuta and Vicia angustifolia than any other crops. The average dry weights of green manure crops were 8.3 ton per ha in tillage and 7.0 ton per ha in no-tillage, among green manure crops that of Secale cereale was the highest. Fertilizer supply was depended on the biomass of the cultivated green manure crops and nutrition contents, total nitrogen supply of V. angustifolia was 226 kg and that of S. cereale was 251 kg per ha in tillage field. In no-tillage field, N-supply of V. angustifolia was 197 kg and that of S. cereale was 222 kg per ha. In yield components of red pepper, fruit numbers per plant were 55.5 in green manure crop tillage and 37.0 in no-tillage cultivation. Among green manure crops, the yield of dried red pepper was the highest for V. angustifolia in both green manure crop tillage and no-tillage cultivation.

본시험은 고추 연작으로 인해 염류가 집적되고 병충해가 빈번히 발생되는 고추 비가림하우스내 동계 녹비작물이 고추의 생육 및 수량에 미치는 영향을 검토하고자 경상북도 농업기술원 영양고추시험장 친환경 고추재배 비가림하우스에서 우리나라에서 겨울철에 월동 가능한 자생콩과 녹비작물을 중심으로 시험을 실시하였다. 다섯가지 녹비작물인 재배완두, 새완두, 살갈퀴, 헤어리베치와 호밀을 가을에 파종하여 이듬해 봄에 녹비작물을 경운과 무경운 상태에서 고추를 재배한 결과는 다음과 같다. 동계 녹비작물의 경운 유무에 따른 건물량은 경운에서 ha 당 8.3 ton이었고, 무경운재배에서는 7.0 ton이었다. 녹비작물별 건물량은 경운 무경운 동일하게 호밀에서 16.6, 14.6 ton으로 가장 많았고, 콩과 녹비작물에서는 살갈퀴가 6.6, 5.7 ton으로 양호하였다. 식물체내 질소 함유량은 살갈퀴와 새완두에서 높게 나타났으며, ha당 질소 공급량은 경운에서 살갈퀴가 226 kg, 호밀이 251 kg이었으며, 무경운재배시 살갈퀴는 197, 호밀은 222 kg이었다. 녹비작물의 경운과 무경운재배에 따른 고추 수량에서 주당 수확과수는 경운재배에서 55.5개로 무경운의 37개보다 18.5개가 더 많아 수량은 7.5 ton으로 무경운에 비해 약 67% 증수되었다. 경운과 무경운에서 공히 녹비작물별 고추의 수량은 질소질 비교의 공급량이 많았던 살갈퀴에서 현저히 많았던 것을 알 수 있었다.
