水稻의 極晩期栽培에 關한 硏究 = Studies on the Lowland Rice Farming Planted Very Late

국문 초록 (Abstract)

水稻의 定時極晩期栽培에 있어서 收量의 減收를 節滅시킬 몇가지 栽培法 卽 苗垈日數 栽植密度 및 株當苗數等에 關한 合理的인 數値를 決定하고저 要因處理에 依한 圃場試驗을 實施하였던 바 그 結果는 다음과 같앗다.
1. 穗數確保를 爲해서 株當苗數를 確保해야 한다는 것을 認定할 수 있었다.
2. 播種期가 遲延됨에 따라서 出穗期 및 成熟期가 遲延되었다.
3. 南部海岸地方에서의 實用的 播種限界期는 6月 17日, 移秧期는 8月 1日이였다.
4. 本畓에서의 生育日數가 짧으므로 生長量의 不足을 苗垈日數의 延長으로 補充하여야겠다.
5. 栽植密度 卽 3.3㎡當 72株와 90株에는 有意性을 認定할 수 없었다.

In order to determine the adequate value of seedling ages, planting space and seedling numbers per hill to diminish yield under the supremely rate seasonal culture of rice, factorial experiment was undertaken, and the result obtained were as follows;
1) It was concieved that seedling number per hill should be secured to retion the numbers of tilles.
2) The later the seedling date, the more the lateness of heading period and mat wring period.
3) Actual limitation date of seedling was june 17th, and transplanting date was August Ist in southern seaside, Korea.
4) Seedling age shoulds he postponad for the complement of the shortage of growth, as the growing date was short in paddy.
5) No statistical significant was conuinced in the terms of plonting density, 72 shares and 90shares per 3.3m².
