【摘要】 红麻是重要天然纤维原料之一,目前其不育系三系配套制种技术已经基本成熟。红麻不育系高产制种试验,结果表明:春播红麻不育系制种以留桩50~75cm,行比1:3最适宜,种子产量达61.38kg/667m2;夏播红麻不育系制种选择扦插茎段高度125~150cm,行比1:2或者1:3皆可,产量分别达58.93kg/667m2和54.47kg/667m2。但春播易受自然干旱和病虫害影响,产量不稳定。因此,建议采用夏播红麻不育系制种方式进行。更多还原

【Abstract】 Kenaf is one of the important natural fiber raw materials,the three-line sterile lines breeding technology of kenaf has mainly been matured at present. The study of high-yield seed breeding test of sterile kenaf showed that stubbles with 50 ~ 75 cm and row ratio with 1: 3 had seed yield of 61. 38 kg /667m2 for the spring sowing breeding. Cutting tips for cuttage with 125 ~ 150 cm and row ratio with1: 2 or 1: 3 had the yields of 58. 93 kg /667m2 and 54. 47 kg /667m2 for the summer sowing breeding.However the spring sowing breeding is easily influenced by natural drought and pest,the yield is not stable. Therefore,the summer sowing breeding is recommended.更多还原
