초록

수출용 단호박의 품질 및 생산성 향상을 위한 비가림 입체재배에서의 적정 재식거리를 구명코자 수행하였다. 재식거리는 120 cm 이랑에 2조식으로 주간거리 30 cm, 40 cm, 50 cm로 하여 하였다. 주지 적심전 생육은 주간거리가 좁았던 처리에서 만장과 생체중, 엽면적이 감소되었다. 수확시의 생육에서는 처리간 생체중의 경우 주간거리 50 cm로 넓었던 처리에서 증가하였다. 암꽃 개화일과, 암꽃 착생마디에서도 차이를 보이지 않았다. 과일 특성에서는 1번과의 과경과 2번과의 과중이 주간거리 50 cm에서 커지는 경향이었다. 평균 과중도 주간거리 30 cm의 1,184 g에 비하여 50 cm에서 1,386g으로 가장 무거웠다. 수확시의 당도에서는 주간 거리간에 차이를 보이지 않았다. 총 수량이 경우 재식주수가 많았던 30 cm 처리구에서 6,510 kg/10a로 가장 많았으나, 과중 130 kg 이상의 상품과의 비율은 40cm 와 50cm에서 98% 이상으로 비슷하였으나, 주간거리가 좁았던 40cm에서 5,012 kg/10a로 가장 많았다.

This study was conducted to determine the optimum planting distance under rain-shielding condition for improving quality and productivity of squash by staking cultivation. The squashes were grown by 3 planting distances, such as 120${\times}$30, 120${\times}$40 and 120${\times}$50 cm during 3 months under non heat condition. The vine length, fresh weight and leaf area were reduced as planting distance was decreased until main branch was pinching. The first female flowering day and first fruit setting nodes were not different among treatments. The first fruit length and second fruit weight were increased in 120${\times}$50 cm planting distance, but the soluble solid contents were not different among treatments. In 120${\times}$30 cm plant distance, total yield was highest (6,510 kg/10a), but marketable yie이 was lowest. When the planting distance was between 120${\times}$40 cm and 120${\times}$50 cm, the marketable rate was similar (over 98%), but marketable yield was highest in 120${\times}$40 cm planting distance (5,012 kg/10a). The results of this study indicated that the optimum planting distance of staking cultivation in squash seemed to be 120${\times}$40cm.
