我队种植高粱面积较大,主栽品种为当地的“牛心头”。该品种产量较低,亩产二、三百斤,且易发生“不稔瞎粒”现象,严重地影响着产量。为此我队技术队在1964年与烟台专区农科所合作,在本队进行了高粱引种试验。茲将结果简报于后。试验材料与方法:引种的高粱皆为杂交种,以雄性不育系的不育七号为母本,以烟台专区的地方品种为父本,共六个组合(见表),以当地 My team planted sorghum larger, mainly cultivated varieties for the local “cow heart.” The yield of this variety is lower, yielding two or three hundred jins per mu, and the phenomenon of “blind and blind grain” is apt to occur, seriously affecting the yield. To this end my team technical team in 1964 with the Yantai Prefecture Agricultural Institute, the team conducted a sorghum introduction test. The results will be briefed later. MATERIALS AND METHODS: The introduced sorghums were all hybrids. Six male sterile lines (male sterile lines) were used as male parents and the other for yamtai local male sterile lines
