Abstract

In this study we investigated the suitability of horticultural main organic root substrate materials (peatmoss, coir) for the development proper root substrate for working with bulb onion transplanter. We investigated seedling sprout ratio, growth and characteristics (bulk density, root substrate cohesion) those are suitable for mechanical transplanting by mixing with inorganic materials(red clay etc.). Although both seedling growth and root substrate bulk density were similar in peatmoss and coir based root substrates, we found that peatmoss mixing had higher root substrate cohesion compared to coir mixing. We assume that higher cohesion properties of peatmoss based root substrate will give more weight of root part during mechanical transplanting of young onion seedlings in the field. Because of this, we suggest that peatmoss is the appropriate ingredient for developing root substrates for working with bulb onion transplanter.

양파 정식기 작업에 적합한 상토 개발을 위해 원예용 유기질 주재료(피트모스, 코이어)의 적합성을 조사했다. 유기질 재료를 무기질 재료(황토 등)와 혼합하여, 묘 출현율, 생육 및 기계정식 적응 특성 등을 조사하였다. 조사 결과 피트모스 혼합 처리구, 코이어 혼합 처리구 모두 묘 출현율, 생육 및 상토 용적밀도에서 유사했으나, 피트모스 혼합 처리구가 코이어 혼합 처리구에 비해 더 높은 상토 응집성을 보였다. 피트모스 혼합 상토의 높은 응집성은 양파 묘 정식 시 뿌리부 무게 증가 등의 효과를 가져와서 정식기 작업 효율성을 증진시키는데 도움을 줄 수 있을 것이라고 생각된다. 이러한 이유로, 양파 정식기 작업에 적합한 상토 개발 시 피트모스를 유기질 주재료로 선정하는 것이 적합하다고 최종 판단하였다.
