| Abstract: | This paper introduced briefly the rapid creation of combination parents, the improvement of hybridization and selection and screening of hybrid combinations as well as the method for improving hybrid rapeseeds,which its focus was on the efficient breeding technology of parents and mechanized production of hybrid seeds. The efficient reproduction of parents was realized by mechanical pollination in net house, the installation was composed by overhead travelling crane, pollination device and outside drive. In net house, the power of outside drive pulled,overhead travelling crane,, the pollination device apparatus walked up and down to make pollination full and saturated. Precise seed planter was used for efficient mechanized production of hybrid seeds , which could adjust flexibly row spacing according to the demand of spraying machine. during sowing, The lanes were reserved first for those machines to spray pesticide and fertilizer, then the spraying machines with high ground clearance was selected and modified its control and spraying systems, It was proved by the experiments and demonstrations in 2013 and 2014 that this machine could realize mechanization in seeds production by chemical hybridization agent and hybrids production in large areas. |
