Abstract

This study was conducted to evaluate potential weed control in organic farming field using false seedbed and stale seedbed techniques. The experiment was conducted in open upland fields during spring and fall crop seasons. The false seedbed was prepared before 2-4 weeks of crop culture and was treated with shallow tillage or flame weeding before transplanting. The weed suppression rates of false seedbed treatment in the spring crop experiments for Chinese cabbage, soybean, hot pepper and corn were 65-73%, 50-55%, 9-55% and 8-33%, respectively. According to crop growth and yield in this experiment, the false seedbed technique has some potential weed control for Chinese cabbage, soybean and corn. The weed suppression rates of stale seedbed treatments in the fall crop experiments for Chinese cabbage, spinach and carrot were 18-39%, 40-77% and 37-38%, respectively. Weed control efficacy of the stale seedbed in this study was lower, when compared with false seedbed.

유기재배 밭에서 가묘상과 헛묘상을 이용한 잡초관리 가능성을 탐색하기 위하여 봄, 가을 노지작물 재배시험을 수행하였다. 가묘상은 작물재배 2-4주 전에 설치한 후 갈퀴를 이용하여 천경하거나 화염처리로 제초하였다. 배추, 콩, 고추, 옥수수를 재배한 봄작기 시험에서 가묘상처리에 따른 잡초억제율은 각각 65-73%, 50-55%, 9-55%, 8-33%로 많은 차이를 나타내었다. 작물의 생육과 수량을 고려할 때 배추, 콩, 옥수수 등은 가묘상을 이용한 잡초관리 가능성이 있다고 판단된다. 헛묘상을 이용한 가을작기 시험은 배추, 시금치, 당근을 재배하였는데 잡초억제율은 각각 18?39%, 40?77%, 37?38%로 가묘상을 이용한 봄작기보다 낮았고 생육과 수량도 좋지 않아 적용 가능성이 적었다.
