白木通人工繁育技术研究

为探讨白木通人工繁育技术,以出苗率和成活率为指标,研究了播种季节、播种方式对有性繁殖的影响,以及扦插种条前处理、扦插用种条的采集时间、扦插用种条的质量、扦插时间4因素对扦插效果的影响。结果表明,播种季节以农历冬至前后播种效果最好;播种方式为种子直播到塑料大棚的营养钵中,并加盖1~2 cm厚的营养土;扦插繁殖中,激素处理对扦插效果影响较大,其中ABT(2号)处理成活率最高;冬季采集种条置湿沙贮藏成活率明显高于其它采集时间所采集的种条;扦插种条的质量直接影响扦插成活率,其中以直接5~8 mm的种条成活率最高;扦插时间对扦插种条的成活起关键作用,其中以3月份扦插效果最好。通过本研究,初步拟定了白木通有性繁殖与无性繁殖技术。

Research on Artificial Propagation Techniques of Caulis Akebiae

To study the technique of artificial propagation of Akebia trifoliate. The effects of sexual reproduction in different planting season and with different planting methods were studied according to seed germination rate and survival rate. The effects of cuttage with different pre-treatment, in different cutting acquisition time,with different cutting qualifies, and in different outrage time were studies according to the survival rate. The best planting season was about lunar winter solstice. The best planting method was to plant seeds diretly in nutrition bowl in greenhouse and cover with 1 - 2 cm thick nutrient soil. In cuttage propagation, the highest survival rate was obtained from ABT （ NO. 2） treatment. The survival rate of cutting collected in winter was higher than that of collected in other seasons. The survival rate of cutting with 5 - 8 mm in length was higher than other length, and the cuttage time was very important to the survival rate, the best cuttage effect was obtained from March. Through this study, the technique of sexual reproduction and asexual propagation of Akebia trifoliate were established.
