초록
벼 무논골뿌림재배시 도복방지를 위한 물관리방법을 구명하고자 동진벼를 5월11일에 골깊이를 4cm로 하여 파종하고 중간 락수 회수를 달리하여 도복형질 및 생육을 검토한 결과를 요약하면 다음과 같다. 1. 상시담수에 비하여 락수회수가 많을수록 절간장이 짧았으며 N
This experiment was conducted to elucidate the effect of the midsummer drainage times on lodging characters, field lodging and yield in direct seeding rice culture in puddled soil. Dongjinbyeo was seeded at May 11 by seeding machine with 4cm of furrow depth and drained, one(50days after seeding DAS)) two (30DAS and 50DAS), and three times (30DAS, and 50DAS and 60DAS). The results are as follows. Culm length was shorten and the wall of N3, N4 were thicken as the drain-age times were increased. As the drainage times were increased breaking weights were increased but the lodging index were decreased. Lodging was occurred seriousely at none drainage, but wasn't occurred two or three times drainage. Yield was higher at 1~2 times drainage compared with none and three times drainage. Therefore, two times midsummer drainage is recommend-able water management method for direct seeding rice culture in puddled soil.
