Abstract

Mechanized operation model and mechanical cultivation technology for winter barley, rye, Italian ryegrass and sudan grass wrap silage production system at the paddy field for cropping system was developed. Also, a series of experiment were performed and lots of data were collected and analyzed to develope mechanical technology, coverage area, and optimum size of the farm (break-even point) for wrap silage production system. The coverage area for winter barley or rye wrap-silage production system is determined around 61.9, 73.4, 77.5, 88.2 ha in the case of drill seeding and different ripening species by tractor power 50, 75, 100, 130 ps, respectably. The break-even point of the farming size is analyzed as 20 ha and its production cost is estimated around 367, 383, 430, 443 won/TDN-kg in the case of winter barley wrap-silage by tractor power 50, 75, 100, 130 ps, respectably. The break-even point of the farming size is analyzed as coverage area and its production cost is estimated around 237, 215 won/TDN-kg in the case of winter barley wrap silage and sudan grass by the tractor power 50, 100 ps, respectably.

본 연구는 겨울철과 여름철에 답리작 사료작물의 랩사일리지 생산에서 연구보고된 조사료 재배품종과 재배방법을 기준으로 하였을 때, 소요 기계에 따른 기계화 생산 작업의 특성과 부담면적, 기계 이용비용을 분석하여 조사료 생산비용을 산출하였다. 생산비용은 작물종류(호밀, 청보리, IRG, 수단그라스), 파종방법(산파, 조파)과 트랙터 마력(50, 75, 100, 130 ps)에 따른 경작규모별(부담면적 ha별), 부담면적대비 경작지비율별(25, 50, 75, 100%), 작부체계별(품종 숙기별, 동 하계 작물별)로 분류하여 산출하였다. 트랙터 100 ps, 조파를 기준으로 단일 품종 재배보다 호밀, IRG와 청보리 등을 품종 숙기별로 재배할 때 파종은 20일에서 30일로, 수확은 약 30일에서 40일로 시기가 늘어나기 때문에 부담면적이 57.1 ha에서 77.5 ha로 증가하였다. 동 하계 작물 연중 재배시 생산비용은 100 ps 트랙터, 조파, kg-TDN 기준으로 호밀+수단은 250원, 청보리+수단은 215원, IRG+수단은 234원, 호밀+청보리+IRG+수단은 233원으로 나타났다. 이는 연중 재배하지 않는 경우에 비해 고정비가 줄어들기 때문에 생산비용은 약 30~50% 절감되었다. 따라서 답리작 사료작물의 랩사일리지 생산시 노동피크와 수확시기의 분산, 기계장비의 효율성을 제고할 수 있도록 품종 숙기별 연중 재배 작부체계의 이용이 바람직한 것으로 판단되었다.
