초록

우리나라 포도원에서 고품질 포도생산에 이용되고 있는 잡초관리 방법들이 병발생 및 수체생육과 과실품질에 미치는 영향을 구명하여 포도재배 농가에 실제적인 잡초관리 방법을 제공하고자 연구를 실시하였다. '캠벨얼리' 품종을 재배하는 비가림 포도원에서 잡초관리방법으로 포도가지 파쇄(C.B.), 흑색부직포(W.F.), 흑색차광망(S.N.), 흑색비닐(P.F.), 왕겨(R.H.), 기계제초 2회(M.W.2), 기계제초 3회(M.W.3)를 무처리와 비교하였다. 비가림 포도원의 피복처리구(C.B., W.F., S.N., P.F., R.H.)와 무피복처리구(M.W.2, M.W.3, U.T.)간 평균온도는 각각 $26.2^{\circ}C$$25.8^{\circ}C$로 비슷하였으나, 피복처리구의 지상부 습도는 피복처리구에서 7월에 90%로 유지되다가 7월 하순 이후 40% 이하로 급격히 낮아져 무피복처리구와 확연한 차이를 보였다. 토양수분은 무피복처리구에 비해 피복처리구에서 모두 높았으나 지온은 대체적으로 피복처리구가 낮았다. 피복처리별 갈색무늬병 발병은 흑색비닐피복에서 무처리 대비 7월에는 85%, 병발생이 높아지는 8월에는 69%의 감소효과를 보였고, 결과모지에서 병반 발생이 가장 적은 것으로 나타났다. 생육특성 중 절간장, 절간경은 무처리에 비해 흑색비닐 피복에서 생육이 좋았고 SPAD값은 흑색비닐 피복에서 가장 높았다. 과실품질 중 당도는 $14{\sim}15^{\circ}Brix$로 큰 차이는 없었으나 흑색비닐 피복에서 약간 높게 나타났다.

This study was conducted to evaluate the effect of weed control on disease incidence, plant growth and fruit quality, and to provide effective method to farmers at the vineyard. At the raincoat greenhouse cultivating 'Campbell Early', several weed controlling methods were compared to the control. Mean temperature of plots between soil covering (C.B., W.F., S.N., P.F. and R.H.) and non soil covering (M.W.2, M.W.3 and U.T.) were similar with $26.2^{\circ}C$ (July) and $25.8^{\circ}C$ (Aug.), but humidity of soil covering was sharply decreased in late-July under 40%. Soil water were all higher in soil covering plots than that of non-soil covering, however, soil temperature was recorded lower in soil covering plots. Disease incidence of Peudocercospora vitis according to soil coverings had effect on black plastic film mulching by decreasing grapevine leaf spot to 85% in July, 69% in August, compared to the control, with showing the smallest lesion incidence in FMB. Among growth characters, internode length and internode width of black plastic film mulching was higher than that of the control. SPAD value of black plastic film mulching was recorded the highest. It was not significant among the treatments, but brix was recorded highly in black plastic film mulching with $14{\sim}15^{\circ}Brix$.
