针对大麦育种,笔者试制了高效率、高质量播种集团选穗或品系选穗的播种机。为了鉴定其特性,还试播了种子量少的不同材料。同时又考虑到,条播比撒播更便于进行系统的观察比较,所以采取了条播的构造。 For barley breeding, the author tried a series of planters with high efficiency and high quality of sowing or selecting ears. In order to identify its characteristics, but also pilot sowing a different amount of different materials. At the same time, it was also considered that the broadcast was more convenient for systematic observation and comparison than the broadcast, so the structure of the broadcast was taken.
