我省新配制的622A 系统高粱杂交种(简称6A 高粱),经1982、1983年区域试验和大面积生产示范结果表明:在相同条件下,比各地主栽的3197A 系统高粱杂交种(简称3A 高粱)增产10.5～30%,且具有高抗丝黑穗病,品质优良,易保苗,耐干旱,制种产量高等优点。但6A 高粱存在茎秆组织较软弱,不抗倒伏的严重缺点。为此,在1982年调查研究的基础上,于1983年组织全省有关单位,开展了6A高粱防倒栽培技术研究的攻关协作。通过一年多点试验研究,对防倒组合的选择,防倒高产 The new 622A system sorghum hybrid (hereinafter referred to as 6A sorghum hybrid) in our province, after 1982, 1983, regional experiments and large-scale production demonstration results show that: under the same conditions than the local 3197A system sorghum hybrids (3A sorghum ) Yield 10.5 ~ 30%, and has high resistance to head smut, good quality, easy to seedlings, drought-resistant, high yield seed production. However, the presence of 6A sorghum stalk tissue is relatively weak, not resistant to the serious shortcomings of lodging. To this end, based on the investigation and study conducted in 1982, the relevant units in the province were organized in 1983 to carry out the research collaboration on the research on the anti-dumping cultivation of 6A sorghum. Through more than a year of experimental research, the choice of anti-down combination, down-proof and high yield
