Abstract

This experiment was carried out to determine the effect of mechanization on lavor-saving in sweetpotato cultivation. The field experiment was conducted from 2005 to 2006 in Mokpo Experiment Station of the National Institute of Crop Science. In order to determine the efficiency of mechanical harvesting, different harvesting methods were compared. Mechanical harvesting method was done as follows: cutting of vines by machine, removal of plastic film mulching, and harvesting by two-row and one-row harvesting system. The result showed harvesting labor was decreased by 66.6% in two-row harvesting. The ratio of damaged sweetpotato by mechanical harvesting decreased by 49.4% in two-row and 38.4% in one-row harvesting compared to conventional method. The total labor cost was saved by 48.2% - 70.4% using mechanical method. In addition, the total income also increased by ca. 62.9% - 81.2%. Thus, it was concluded that mechanical harvesting is more efficient and economical method than conventional one.

고구마 수확단계에서 작업체계에 따른 생력효과를 조사하고자 순치기와 1열식과 2열식 수확기를 이용하여 시험을 수행한 결과를 요약하면 다음과 같았다. 1. 고구마 수확단계 작업체계는 순치기+비닐제거+2열식 기계수확 +인력굴취가 ha당 106.4시간, 순치기+비닐제거+1열식 기계수확 +인력굴취가 ha당 111.3시간 및 순치기와 비닐제거 작업을 생략하고 1열식 기계수확+인력굴취가 당 107.6시간으로 관행(인력 333.2시간/ha) 대비 각각 68.1%, 66.6% 및 66.8%의 생력효과가 있었다. 2. 고구마 손상개수율은 인력수확이 8.6%인데 비해 기계 2열식이 4.4%, 기계1열식이 5.3%로 약 43.9%가 적게 발생되었으며, 품종에 손상개수율은 연미 6.2%, 신천미5.1%, 하얀미 4.7%, 건미 3.4% 순으로 차이가 있었다. 3. 수확단계 비용절감효과는 ha당 고구마 손상개수율을 포함한 수확단계의 비용이 관행(인력) 2,963천원에 비해 고구마 순치기와 수확기의 이용에 의해 62.9~81.2%인 1,865~2,406천원 절감되었다.
