1.引言日本福岛县水稻种子繁殖上的收获和干燥作业体系是割捆,自然干燥、自动脱粒皮。但因很少专门繁殖种子的农户,所以操作上就分为繁殖种子和普通栽培两部分。因此,有自动脱粒型康拜因的农户坚持使用康拜因收打种子,所以进行了水稻收打种子的机械化试验。以繁殖种子为目的的收获作业,如用以前使用的自动脱粒型康拜因,由于滚筒上的刀刃或接受种子的网罩与种子的冲撞等,造成伤谷而难以保证高质量的稻种。为此,当进行试验 1. Introduction Fukushima Prefecture, Japan rice seed multiplication harvesting and drying operating system is cut bales, natural drying, automatic threshing skin. However, due to very few specialized breeding of farmers, so the operation is divided into breeding seeds and ordinary cultivation of two parts. As a result, farmers with automatic threshing Kangbayin insisted on using the Kangbayin harvesting seeds, so mechanized tests of harvesting rice seeds were conducted. Harvesting for the purpose of breeding seeds, such as the previously-used automatic threshed combinan, is difficult to ensure high-quality rice due to wounding of the grain due to the collision of the blade on the drum or the seed-receiving grille with the seed. For this reason, when conducting the test
