초록

벼 담수직파재배에서 잡초 경합밀도별 쌀 수량 감소는 새섬매자기의 경우, $m^2$당 24본 이상에서, 미국외풀은 48본 이상에서 유의적으로 낮아졌으며 새섬매자기($m^2$당 192본)와 미국외풀($m^2$당 386본)의 최대 경합밀도에서 각각 43%, 22% 정도 감소되었다. 새섬매자기 발생밀도에 따른 수량 예측 모델식은 Y=531.3kg/(1+0.003931x), $r^2$=0.964, 미국외풀은 Y=547.0kg/(1+0.000792x), $r^2$=0.922으로 나타나 벼에 대한 새섬매자기의 경합력이 미국외풀 보다 약 5.0배 정도 큰 것으로 나타났다. 또한, Cousens(1985) 방법에 따른 초종별 경제적 방제수준은 새섬매자기는 $m^2$당 7.2본, 미국외풀은 34.9본으로 나타나 이에 비해 잡초 발생밀도가 높을 때는 방제하는 것이 경제적으로 유리할 것으로 판단되었다.

This study was conducted to find the levels of reduction in rice yield and to determine economic threshold levels as affected by densities of Scirpus planiculmis and Lindernia dubia in wet seeding rice cultivation. In wet seeding rice cultivation, yield of rice in densities of S. planiculmis (192 per $m^2$) and L. dubia (384 per $m^2$) was reduced by 43 and 22%, respectively. Relationship between rice yield and densities of weeds were predicted with these equations of Y=531.3kg/(1+0.003931x), $r^2$=0.964 for S. planiculmis and Y=547.0kg/(1+0.000792x), $r^2$=0.922 for L. dubia. According to Cousens' method, economic threshold densities of S. planiculmis and L. dubia were calculated by 7.2 and 34.9 per $m^2$, respectively. This result indicated that yield of rice in wet seeding rice cultivation could be reduced by over economic threshold densities of S. planiculmis and L. dubia.
