Abstract
본 연구는 친환경 차나무 재배에서 월동 풋거름작물 재배시 차나무의 생육특성 및 잡초발생에 미치는 영향을 알아보고, 차나무 관리에 유용한 초종을 선발하기 위한 기초적 자료를 얻기 위하여 수행하였다. 무처리의경우 13종의 잡초 229주, 생체중 4,344 g (건물중 745 g)이 조사되었으며, 크림슨클로버 처리에서 가장 적은 3.7 종의 잡초 14.7주, 생체중 18.0 g (건물중 1.1 g) 조사되었으며, 모든 풋거름작물 처리구에서 98% 이상 잡초방제효과가 있었다. 토양유기물 함량은 무처리 14.1 g/kg으로 가장 낮았으며, 크림슨클로버 처리에서 가장 많은 2.2 배 증가한 30.5 g/kg 함량을 보였다. 차나무 생엽의 엽록소함량은 무처리 38.1, 들묵새 처리 38.3, 자운영 처리40.1, 크림슨클로버 처리 41.9로 조사되었으며, 엽록소형광에서도 크림슨클로버 처리 0.804 Fv/Fm로 가장 높았다. 잡초억제, 토양개선효과, 차나무 생육 등을 고려하였을 때, 차나무의 풋거름작물로 크림슨클로버가 가장 적합한 것으로 사료된다.This study examined the effects of green manure on the growth characteristics and weed control for tea trees in organic tea cultivation. The weed control, soil chemistry, SPAD value, and chlorophyll fluorescence were examined with five different treatments [Festuca myuros (FES), Astragalus sinicus (AST), Trifolium incarnatum (TRI), mixing sowing (Astragalus sinicus 1 + Trifolium incarnatum 2) and control]. The weed occurrence was 229 weeds of 13 flora (fresh weight 4,344 g, dry weight 745 g) in control; TRI treatment was the lowest, 14.7 weeds of 3.7 flora (fresh weight 18.0 g, dry weight 1.1 g). The mulching treatment groups showed a weed inhibition effect compared to the control (over 98%). Organic matter was lowest at 14.1 g/kg, but highest at 30.5 g/kg (2.2 times) in the TRI treatment. SPAD value and chlorophyll fluorescence of tea leaves were also highest in the TRI treatment (38.1, 41.9 Fv/Fm). Therefore, Trifolium incarnatum is considered the most effective when considering weed control, soil chemical properties, growth of tea trees, and convenience of work.
