摘要
影响大白菜杂交制种产量的因素很多,其中亲本种株壮苗率、栽培密度、花枝数量、授粉好坏是影响产量的几项重要因素。作者结合大白菜87-114杂交制种,进行了双膜覆盖育苗、栽培密度试验、主苔摘顶试验、人工辅助授粉及放养蜜蜂授粉试验等试验研究,取得比较好的效果,在实践中加以应用,产量有了明显提高,已经成为大白菜杂交制种必不可少的几项关键技术措施。
There are many factors that affect the yield of Chinese cabbage hybrid breeding,among which the rate of seedling,cultivation density,number of flower branches and pollination are some important factors affecting yield.To this end,we combined with Chinese cabbage 87-114 hybrid breeding,double-film cover seedling,cultivation density test,main moss top removal test,artificial auxiliary pollination and breeding bee pollination test and other experimental research,achieved better results,in practice,the application,yield has been significantly improved,has become the Chinese cabbage hybrid breeding essential to several key technical measures.
