【摘要】 通过对红天麻和乌天麻生长繁殖周期的研究,初步建立了一种缩短天麻一代生长繁殖周期所完成的时间和季节历期的技术体系。具体方法是:(1)应用控温技术;(2)利用海拔(100~1 500 m)和气候(宜昌—海南岛)的差异,分段种植天麻。此法可将天麻箭麻—开花—种子—白麻这一生长发育阶段调控并固定在任一时间或季节里。运用此方法已将云南有性乌天麻箭麻的生长周期由28个月缩短到17个月,且保持品质优良;宜昌红天麻和乌红杂交天麻种子—种子的生长周期由24个月缩短至12个月以内。更多还原

【Abstract】 The technology system has been established to shorten the time for finishing one generation life cycle of Gastrodia elata Bl.and the seasons lasting.Methods:(1) Use the technique of control temperature;(2) Grow G.elata Bl.in districts by making use of the climate differences caused by the altitude(100 to 1500 metres) and geographical positions(from Yichang to Hainan island).The growth cycle(mature tuber-flowering-seed-immature tuber) can be fixed in any time or season by these two(methods).It is true for us to shorten the life cycle of sexual G.elata Bl.f.glauca S.Chow in Yunnan from twenty-eight months to seventeen months,and keep the good quality.We have also shortened the life cycle of the seeds of G.elata Bl.f.elata in Yichang and the crossbreed between G.elata Bl.f.elata and G.elata Bl.f.elata from twenty-four months to twelve months.更多还原
