摘要
应用固定日长加蓝光与远红光作辅助光照诱导甘蔗开花，使甘蔗与抗逆性及再生性强的斑茅、芒等，通过解决母本花穗去雄、父母本花期不遇和属间杂交不孕等一系列障碍，实现属间杂交成功，定向培育出亚热带地区既耐旱耐瘠又高产优质、终年可供青料的牧草新物种。经过几年的探索，目前已初步选育出若干优异的牧草蔗新品系，其产量及品质均优于对照的甘蔗良种，且在天然条件下终年不开花结实，冬季不枯萎，四季常青，可解决冬季、早春青料供应短缺问题。
Some fine sugarcane varieties were induced to bloom by photoperiodic treatment with blue and farred light The intergeneric hybridization between sugarcane and Sarundinaceum, sugarcane and Miscanthus anderss have been achieved by settling the technical barriers, ie spike castration of female plants; unsynchronization of flowering periods between male and female plants; and infertility of intergeneric hybridization The new foragegrass hybrid progenies have been supplied as green fodder all the year round because of their nonflowering and nonwithering characters in the natural condition of subtropic area
