小麥의 粒質向上과 增收를 위한 栽培方法 改善에 關한 硏究 = Studies on the improvement of the cultivation method for high quality grain texture and high yield of winter wheat

국문 초록 (Abstract)

小麥의 粒質向上과 增收를 위한 栽培方法 改善策을 究明하기 위하여 1977年 9月부터 1978年 8月까지에 걸쳐서 建國大學校 農科大學 附屬 實習農場에서 實施한 播種期, 追肥時期 및 施肥量 等에 관한 一連의 試驗結果를 要約하면 다음과 같다.
1. 小麥의 粒質向上과 增收를 위한 適正播種期範圍는 9月 25日부터 10月 25日까지라고 認定되었다.
2. 小麥栽培期間中 單一回만의 追肥를 實施하는 境遇 適正追肥時期는 3月 25日頃이라고 認定되었다.
3. 小麥의 種實數量은 窒素, 燐酸 및 加里 等 三要素 다함께 二倍肥量까지는 施肥量이 增加할수록 增大되었다.
4. 種實內 蛋白質含量은 窒素, 燐酸 및 加里 等 三要所 다함께 二倍肥量까지는 施肥量이 增加할수록 많아졌다.
5. 種實內 灰分含量은 燐酸施肥量이 많을수록 減少되었으며, 窒素 및 加里의 施肥量 그리고 播種期 및 追肥時期 等 要因의 影響은 적은 것으로 나타났다.
6. 製粉率은 播種期가 늦어지는데 따라서 增加되고 窒素施肥量이 增加할수록 低下되는 傾向을 나타냈으며 燐酸 및 加里의 影響은 적은 것으로 認定되었다.

These studies were carried out to investigate the improvement of the cultivation method for high quality grain and high yield of wheat grains at the experiment farm of Kon-Kuk University from Sep. 1977 to Aug. 1978. The result of seeding time, the top-dressing time and the application amount of nitrogenous, phosphatic and potasium fertilizer to be obtained from the above experiments are as follows:
1. It was recognized that the range of adequate seeding time for increasing the yield and high quality grain texture of wheat grains were from Sep. 25 to Oct. 25.
2. It was recognized that the adequate top-dressing time in case of the top-dressing applied only one time, during the growth-period of wheat was around Mar.25.
3. The yield of wheat grains showed tendency to increase, as the application amount of nitrogenous, phosphatic and potasium fertilizer were increased to N-P-K = 24kg-16kg-14kg per 10a.
4. As the application amount of nitrogenous, phosphatic and potasium fertilizer were increased to N-P-K = 24kg-16kg-14kg per 10a, the protein contents of wheat grains showed tendency to increase.
5. As the application amount of phosphatic fertilizer was increased, the ash contents of wheat grains were decreased and the influence of the factors such as the application amount of nitrogenous and postasium fertilizer, seeding time and top-dressing time, showed little effect.
6. As seeding time was delayed, the flour milling percentage of wheat grains were increased, and as the application amount of wheat grains showed a tendency to decrease and the influence amount of phosphatic and potasium fertilizer showed little effect.
