담배의 엽탈락, 품질 및 수량에 미치는 석회와 붕사의 영향을 알고자 시험한 결과를 요약하면 다음과 같다. 1. 엽탈락 이식후 40～80일에 많이 발생되며 불위엽에서 상위엽으로 진행된다. 2. 석회의 시용은 엽탈락을 조장하나 붕사는 엽탈락을 현저히 감소시켰다. 3. 석회의 시용은 전당, Lignin, 붕소함량을 감소시키며 붕사시용은 붕소와 Lignin 함량을 증가시킨다. 4. 붕사의 1년시용으로 엽탈락의 완전방지는 어려웠다. 5. 석회와 붕사의 시용량은 각각 120kg/10a,1.2kg/10a가 엽탈락방지와 품질, 수량성으로 보아 적정시용량으로 인정되었다.

This experiment was carried out to study the influence on the abscission of tobacco green leaves, yields and quality by the application of lime and boras. The results obtained are as follows; 1. The breakdown of tobacco green leaves occurred from 40 to 80 days after transplanting. According to the progress of growing stage, the breakdown leaves advanced to upper leaves in stalk position. 2. The number of breakdown leaves were increased by application of lime and application of borax have a remarkable effect for the control of breakdown leaves. 3. Application of lime were decreased to total-sugar, lignin and borone but borax were increased to borone and lignin content in leaf tobacco at 50 days after transplanting time. 4. It was found that perfective prevention of breakdown leaves could not deped on annual application of borax. 5. The optimum amount of lime and borax were found that lime was 120kg/10a and borax was 1.2kg/10a for the prevention of breakdown leaves, yields and quality.
