以光钝感苎麻 NG1 为材料 ,于三麻现蕾始期摘除花器 ,每 7天收获一次种子和原麻 ,并与同期收获的自然开花结实株 (ck)比较。结果发现 :虽然同期收获的开花结实株的原麻产量低于摘除花器株 ,但前者的单纤维支数反而高于后者。种子成熟期迟于纤维工艺成熟期两个星期 ,于种子成熟期收获 ,NG1 的单纤维支数比工艺成熟期下降仅5 .2 0 % ,原麻产量提高 4.0 4% ,而种子增重达 2 6 .11%。说明种子成熟期的光合产物主要运往种子而不是韧皮纤维。三麻油、纤兼收对单纤维支数的提高是有利的 ,因为苎麻生产中三麻的实际收获期远远迟于纤维工艺成熟期
Light ramie ramie NG1 was used as material to excise flower organs at the beginning of bud trimming period and seeds and primary burdock were harvested every 7 days and compared with those of the natural flowering stubble (ck) harvested at the same period. The results showed that although the yield of the first seed of the flowering and fruiting plants harvested in the same period was lower than that of the aborted plant, the single filament number of the former was higher than the latter. The maturity of the seeds was two weeks later than the maturity of the fiber technology and was harvested at seed ripening stage. The single fiber count of NG1 was only 5.200% lower than the maturity of the technology and the yield of the crude hemp increased 4.04% 2 6 .11%. It shows that the photosynthate of seed maturity is mainly transported to seeds rather than bast fiber. Three sesame oil, fiber and income on the single fiber count increase is beneficial, because the actual production of ramie three Ma harvest period is far behind the fiber maturity
