초록

이 연구는 3년근 도라지 이식 재배기간 동안 피복재료에 따른 뿌리의 생육특성 및 잡초발생 양상을 알아봄으로써 유기재배 도라지생산을 위한 기초자료로 활용하고자 실시되었다. 1. 뿌리의 직경은 피복구의 평균은 28.1 mm로 무피복구보다 5.1 mm 굵게 나타났으며 필름 피복구에서 30.9 mm 로 가장 굵게 나타났으며, 길이는 왕겨 피복구에서 가장 짧은 22.0 cm로 나타났다. 곁뿌리 수는 필름피복구에서 36.0개로 가장 많았고 무피복구에서 가장 적은 수가 조사되었다. 2. 뿌리 생체중에서는 피복구처리와 무피복구 간의 비교에서도 평균 100과 56 g/root으로 뚜렷한 차이를 보였으며 필름 피복구에서 130 g/root으로 가장 무거웠으며, 다음으로 톱밥 및 왕겨 피복구 순으로 104, 67g/root 나타났다. 3. 피복구는 무피복구에 비하여 잡초 억제 효과가 있었으며, 무피복구의 우점잡초는 강아지풀, 바랭이, 피복구의 우점잡초는 강아지풀로 나타났으며, 일년생 화본과 잡초가 평균 잡초발생의 72%를 보이며 각 피복구에서 높은 우점율이 나타났다. 4. 잡초 발생개체수에서는 무피복구에서 125 개/$m^2$ 가장 많았으며, 피복구에서는 생분해성필름 피복구에서는 전혀 발생하지 않았으며, 톱밥 피복구는 18 개/$m^2$로 무피복구에 대비 14.4% 발생율이 나타나, 피복처리시 잡초 억제 효과가 뚜렷하게 나타났다.

This study was conducted to elucidate the effects of mulching materials on root growth characteristics and weed occurrence of Platycodon grandiflorum transplants (3 years old) in organic farming. After transplanting, roots were mulched with one of three mulching materials (biodegradable film, sawdust, or rice husks) or a control (no mulching). The average root diameter of all mulching groups was 28.1 mm, which was 5.1 mm thicker than the no-mulching treatment. Roots with the biodegradable film treatment were the thickest at 30.9 mm. Root length was the shortest, 22.0 cm, with rice husk mulching. The number of rootlets was the highest with film mulching (36.0 rootlets/root) and the lowest with no mulching. For root fresh weight, which directly affects yield, the average of treated and untreated roots was 100 and 56 g/root, respectively. The highest fresh weight was in the biodegradable film plot (130 g/root). The mulching treatment groups showed a weed inhibition effect compared with the no-mulching treatment. The dominant weeds with the no-mulching treatment were Setaria viridis and Digitaria ciliaris, and that with the mulching treatment was Setaria viridis. Average annual weed occurrence across all treatments was 72%. Weed occurrence was the highest with the no-mulching treatment ($125weeds/m^2$), and there were no weeds with the biodegradable film treatment.
