我县从1964年开始种植“云油6号”油菜。由于坚持隔离繁殖油菜种子,使油菜生长整齐,成熟一致,病害减轻,纯度提高,产量比对照田增加15—30%。我们重点抓了两方面的工作:一是采取县、社两级集中繁殖的方法。县一级选择具备隔离繁殖条件的生产队为基地,为公社生产原种,各公社选重点生产队,用县一级提供的原种,再繁殖一级种子,供生产队大田生产用种。全县各生产队的生产用种,一般2—3年即可更换一次。二是建立群众性的良种繁育组织。在县、社两级良种繁育基地,建立三结合的科技小组,县农业技术部门,除定期举

County-level production team with isolation and breeding conditions as the base for the commune production of the original species, the commune selected key production team, with the county level to provide the original species, and then breed a seed for the production team Daejeon species. Production of the county’s production team species, usually 2-3 years to be replaced once. Second, the establishment of mass breeding breeding organizations.
