한지형 마늘의 엽초유인 방법에 따른 마늘 엽 생육과 수량 에 미치는 영향을 구명하고자 관행유인, 비닐절개유인, 일시제 거유인 등 3처리를 두어 실험을 실시한 결과, 초장은 생육 초 기 일시제거유인에서 좋았으나, 생육 후기로 갈수록 차이가 없 었으며, 엽초경은 4월 상순까지는 비슷한 생육을 보였으나, 생 육후기로 갈수록 일시제거유인에서 저조하였다. 엽록소 함량 은 비닐 일시제거 유인에서 SPAD값이 46.0~62.5로 변화폭이 컸던 반면, 관행유인은 3.0(SPAD값)으로 변화폭이 적었다. 엽 초유인 방법별 토양온도는 관행 및 비닐절개 유인에서 최고· 최저 온도차가 비닐 일시제거유인에서는 14oC로 온도의 변화 폭이 컸다. 구중은 관행 및 비닐 절개 유인에서 무거웠으며, 1,000당 투하노동력은 비닐절개구와 비닐 일시제거구에서 관 행 66.5시간/2인 대비 각각 17.3%와 18.3%의 점감효과가 있 었고, 1,000당 수량은 비닐절개 유인이 751 kg로 관행유인 686 kg에 비해 9% 증수되었다.
To investigate the effect of leaf sheath training by P.E film incise on the plant growth and yields in northern type garlic, three treatments including the general training (Control), the P.E film incise training and the all-at-once removal training were conducted. The plant height was the best in the all-at-once removal training at the early growth stage, but there seemed to be little difference in the late growth characteristics. The growth of leaf sheath was not different at the early of April, but lower at the latter period in the all-at-once removal training. The changes of chlorophyll contents were severe, particularly, the SPAD values were 46.0 to 62.5 in the all-at-once removal training, on the other hand, that values were 3.0 in general training. The soil temperature difference between the general training and the P.E film incise training treatments (12) were heavier than that of the all-at-once removal training (14), and the soil moisture difference was little in the P.E film incise training. In the general training and the P.E film incise training, the bulb weights were somewhat higher. The index of bulb shape was 0.85 in the general training, but 0.82 in the all-at-once removal training. The products amount per 10a (751kg) increased by 9% in the P.E film incise training.
