과산화석회 분의와 파종량이 침수 토중직파재배 벼의 입모와 수량에 미치는 영향
Seedling Establishment and Yield of Direct Subsurface Seeded Rice as Influenced by $CaO_2$ Coating and Seeding Rates
초록
벼 침수직파재배법 확립을 위해 파종량과 산소 발생제 처리를 달리하여 침수토중직파재배 싱험을 실시한 결과를 요약하면 다음과 같다. 1 침수토중직파에서 CaO
To establish the direct seeding cultivation method in rice (Oryza sativa L.). direct subsurface seeding with different oxygen suppliers and seeding rates was conducted from May to Oct. 1989. at the experimental field of Suncheon National University. In direct subsurface seeding. calcium peroxide enhanced the ratio of seedling establishment. However. as number of plants per unit area increased. the occurrence of field lodging became progressively severe. so that the enhanced seedling establishment did not increase the yield. The optimal seeding rate and the number of sowing seeds per equally spaced spot were estimated to be 3.3Kg seeds/l0a and 3 seeds per spot with CaO
