川香2058是用优质香型不育系川香29A与自选优质高配合力恢复系黔南恢2058组配选育而成的迟熟籼型三系杂交水稻新组合。为促进该组合在生产上的应用,于2009~2010年在贵州省岑巩县对川香2058的制种技术进行了探索。在介绍了川香2058父母本特征特性的基础上,从制种基地选择;合理安排播差期;采用分段式育秧;科学安排父母本行比;统筹肥水管理;巧用激素调整花期;做好人工辅助授粉;综合防治病虫草害;及时除杂除劣,确保种子质量等方面阐述了川香2058的制种技术。
Chuanxiang 2058 is a new combination of late-maturing indica three-line indica hybrid rice with high quality Aromatic CMS line Chuanxiang 29A and optional high quality and high yield restorer line Qiannanhui 2058. In order to promote the application of this combination in production, the seed production techniques of Chuanxiang 2058 in Cen Gong County, Guizhou Province from 2009 to 2010 were explored. On the basis of introducing the characteristics of parental characteristics of Chuanxiang 2058, the paper chooses seed production base, arranges sowing period reasonably, uses segmented seedling raising, arranges parental ratio, arrange fertilizer and water management scientifically Good Artificial pollination; comprehensive prevention and control of pests and diseases; timely removal of impurities in addition to ensure the quality of seeds and other aspects of Chuanxiang 2058 seed production technology.
