옥수수와 콩을 혼작하였을 때 단백질 함량을 높이고 생산량을 높이기 위해서는 두 종자 간격이 5~10cm 이내가 되어야 한다. 기존 파종기는 조간 간격을 20cm 이내로 좁히지 못하기 때문에, 혼작 파종의 생산량이 저하되고 작업시간과 노동력이 많이 소모된다. 이에 본 연구에서 혼작 파종에 사용되는 콩과 옥수수 종자의 기계적 기하학적 특성 분석을 바탕으로 혼작용 파종기를 개발하였으며 성능실험을 통하여 농가적용 가능성을 판단하였다....

Seeds of corn and soybeans should be sown 5 to 10 cm apart in simultaneous cultivation to increase productivity. However, it’s impossible for general sowers to plant at spacing of less than 20 cm. Thus, mixed cultivation of corn and soybeans is currently seeded with a tractor and then manually planting soybean seeds. This method results in irregular spacing between seeds, laborious and time consuming work. In this study, the physical characteristics of corn (P32P75) and soybeans (W4) seeds were measured to develop a dual sower, Capable of simultaneous sowing of corn and soybeans for mixed cultivation. A seed metering equipment was designed using the EDEM software. Based on the design obtained, a prototype sower for mixed cultivation was built. The sowing spacing between seeds, depth of soil over planted seed, and sowing performance were evaluated. The EDEM simulation results indicated that a 6 mm in width and 3 mm in depth grooved seed-delivering roller had the highest particle mobility of the designs considered, with a 2.5% misplanting rate. A performance test showed that no misplanting occurred in the sections sown with soybean seeds at a seeding spacing that averaged 27 mm but occurred in one section sown with corn at a seeding spacing average of 215 mm. The sowing field capacity for both corn and soybean was found to be 0.7 h/10a. The average depth of soil over seed was 28.7 mm for soybean and 41.6 mm for corn. These average depths are within the recommended range for the depth ranged 5 to 10 times of the seed size.
