水稻增收에 關한 硏究 = Studies on Increased Yield of Rice

국문 초록 (Abstract)

本試驗 結果 米穀 增收의 要件으로 客土와 深耕에 依한 作土層을 增加시킴과 아울러 有機物의 含量을 높이고, 따라서 水?生育에 重要한 要素로 알려진 珪酸質 肥料의 施用 및 不足 ?類를 보충함과 同時에 灌排水 管理 및 耕種關係를 合理的으로 함으로서 現在의 平均 玄米收量 보다 높은 數値의 結果를 얻었다.
(1) 客土를 反當 7,500kg 程度 施用함과 有機物 및 ?類 補充으로 莖數, 穗數가 10%, 玄米收量이 12% 增加하였다.
(2) 深耕에 依한 作土層의 깊이를 10∼12cm에서 18cm 程度 깊게 함과 同時에 有機物 및 ?類補充으로 客土와 같은 傾向의 成績을 얻었다.
(3) 客土와 深耕을 같이 處理한 結果, 客土, 深耕, 單用區에 比하여 莖數, 穗數의 增加는 약간 보았으나 收量面에서는 크게 增加를 보지 못하였다. 이는 當年에 客土, 深耕으로 作土層을 增加시켰다 하드라도, 土壤의 熱度가 잘 이루어 지지 못하였기 때문에 야기된 것으로 본다.
(4) 二條竝木區로 坪當 株數를 늘이므로써 收量增加는 認定되지 않았다. 이는 3의 경우와 같다고 하겠으나 他區 역시 坪當 株數가 90株였기 때문으로 본다.

To study about an increased yield of rice, this experiment was carried out at five county selected in Kyung Nan province.
The essential conditions of increased yield obtained from this experiment were as follows:
1) Supplying with red clay soil to 7,500kg per 10are some of organic matter and mineral nutrition into each field, the stem and ear was increased in number to ten per cent and an unpolished rice to twelve per cent.
2) The coincident results were obtained in deep plowing treatment in order to plow more deep the sub-soil floor of 10∼12㎝ to 18㎝ with supplement of organic matter and mineral nutrition.
3) When the above mentioned two treatments were done together, the stem and ear was moderately increased in number compare with each if the depth of sub-soil was increased according to the supplement of red clay soil and decper plowing, howerer, the soil was not efficiently development during one year for plant to grow well.
4) The two strips planting to increase the number of plant per 0.245 acre was not increased in yield of an unpolished rice. It was seems that the reason also was same as in 3., and that the number of plant was epually ninety in the other all experimental treatment.
