다국어 초록 (Multilingual Abstract)

Korean insam(ginseng) is recognized as an indigenous crop of Korea. Direct seeding and transplanting technology were introduced in 1700years already. Dimensions of the seed bed for insam(ginseng); width of ridge is 120cm and width of furrow was 90cm in those times but width of ridge is 90cm and width of furrow is 90cm in modern times. The planting distance of insam(ginseng) was 4.0cm × 3.6cm(20lines 50rows) and 1,000grains/3.3㎡ with seeding scale (2lines × 20holes) 100 years ago. Nowadays big grain insam(ginseng) seeds planted 3.6cm × 3.6cm(1,200grains/3.3㎡), small grain insam(ginseng) seeds 3.0cm ×3.0cm(1,740grains/3.3㎡) were planted. The planning density was 20% increased for big grain insam(ginseng) seeds and 70% increased 70% for small one. The height of sun roof in 1800years was higher than modern time`s sun roof. Cultivation of insam(ginseng) was increased various region of Korea recently. But cultivation of insam(ginseng) is one of the most laborious operations requiring an extended human labor hours. Due to the reason, it is necessary to reduce the cost of production and save the labor cost. Cultivation machinery of insam(ginseng) asked to develop for every working step. Thus, developed for insam(ginseng) cultivation equipments such as ridger, direct seeder, transplanted, digger was introduced to insam(ginseng) farmer now days. But it is very difficult to do work under the sun roof after plant insam(ginseng) because of small scale shadows system. It must be improved to be operating easily with big tractor inside of the sun roof of insam(ginseng) cultivation.
