초록

펠렛종자를 점파용 파종기로 이용하여 기계화 정밀파종 함으로써 나종자를 손 작업에 의존하여 파종하는 것보다 파종시간과 솎음시간을 각각 225시간 및 460시간 절감할 수 있었고, 종자량도 72% 절감 할 수 있었다. 인력에 의한 손 파종은 파종과 솎음작업에 1 ha당 720시간이 소요되었으나, 펠렛종자를 이용한 기계화 파종은 35시간에 불과하였다. 따라서 펠렛종자를 기계화 파종함으로써 나종자를 인력에 의존하여 파종하는 관행방법에 비해 파종과 솎음작업의 생력효과를 95% 이상 높일 수 있었다. 펠렛종자의 묘출현율은 무처리 종자보다 출현율이 8% 정도 낮았고 출현속도도 약 1.9일 정도 지연되었으나 35일 경과된 유묘의 초기생육에는 큰 차이가 없었다. 유묘출현 반응은 품종에 따라 약간의 차이는 있으나, 펠렛종자는 나종자나 SMP 처리종자에 비해 출현율이 저하되었고 출현속도도 늦었다. 그러나 SMP 처리하여 종자활력을 증진시킨 후 펠렛하면 출현율도 향상되었고, 묘출현속도도 1일 정도 빨랐다.

This study was carried out to develop and investigate integrated mechanization system for culture of carrot. Compared with the conventional hand planting, use of a mechanical planter for pelleted seeds resulted in a saving of planting time by 225 hours. An additional saving of 460 hours was obtained for thinning the seedlings. Besides seeds could be saved by 72%, planting and thinning be done only in 35 hours per ha field when the pelleted seeds were planted with a planter. Work hour reduced by adopting the mechanical planting of pelleted seeds sharply contrasted to that of 720 hours required for hand-planting the thinning hours, resulting in a reduction of labor by more than 95%. SMP followed pelleting tended not only to increase the percentage of seedling emergence in the field but to induce an a day earlier germination.
