참깨의 비닐피복 기계화 일관작업 체계 연구

This study was carried out to develop and investigate integrated mechanization system on polyethylene(P.E.) film mulching culture in sesame. Field trials were carried out to develop optimum mechanics for each step of manual operation in sesame culture and demonstrated those developed mechanics of sesame dibbling vinyl mulcher, sesame binder, sesame thresher and sesame grader at the farmers field of Hwasong (Kyunggi-do) in 1994 and 1995. Newly developed sesame dibbling vinyl mulcher brought saving manpower 280 hrs/㏊ for sowing and P.E. film mulching with it`s 98% of labour saving for the harvesting operation of sesame. Sesame Binder showed 93% labour saving for cutting and binding with only 22 hrs/㏊ compared to 330 hrs/㏊ that of conventional. Sesame thresher was appeared to have 85% effects of labour saving for threshing with completely dry sesame bundles at one time by 23 hrs/㏊ compared to 151 hrs/㏊ that of conventional. Sesame grader was appeared to have 72% effects for sesame grain grading with 12 hrs/㏊ compared to that of conventional 54 hrs/㏊. Grain yield of integrated mechanization culture system showed 6% higher than that of coventional. Integrated mechanization culture system (sesame dibbling vinyl mulcher + sesame binder + sesame thresher + sasame grader) showed 62% of labour saving effects through whole steps of sesame culture by 472 hrs/㏊ compared to that of conventional 1,230 hrs/㏊.
