질소시비량 및 재식밀도가 수도 백엽고병 발병에 미치는 영향
Effect of Nitrogen Fertilizer Level and Planting Density on the Occurrence of Bacterial Leaf Blight of Rice
초록
실소시비량 및 재식거리간 벼 흰빛잎마름병 발병과 관계를 조사한 결과는 다음과 같았다. 1. 질소시비량과 발병과는 시비량의 증가에 따라 발병율이 많아지는 경향을 나타냈으며, 7.5kg/10a<15kg/10a<30kg/10a의 순으로 발병이 높았다. 2. 질소시비량이 배비(30kg/10a)일 경우에는 재식거리와는 관계없이 전체적으로 높은 발병율을 나타내었다. 3. 표준시비구(15kg/10a)에서는
In order to investigate the relationship among the occurrence of bacterial leaf blight, amount of nitrogen application and planting density, a field experiment was carried out with factorial combinations of N levels (7.5, 15, 30kg/10a) and planting densities (10\times20,\;15\times30,\;20\times40cm). The results obtained in this study were; (1) The incidence of bacterial leaf blight was increased with increase of nitrogen application; (2) In double amount of nitrogen application (30kg/10a), the incidence of bacterial leaf blight was higher, regardless of planting density; (3) The incidence of bacterial leaf blight in Standard nitrogen application was significantly higher
