一、繁殖方法1.无性繁殖。利用采挖的野生白芨,通过无性繁殖方式逐步培育、积累种苗。缺点是野生资源少,积累大规模的种苗导致周期较长,而且长期多代无性繁殖,会出现种苗退化,抗病性降低。2.种子繁殖。利用白芨种子进行繁殖。缺点是白芨种子没有胚乳,寿命短,而且对荫发条件要求较高,很难荫发,其幼苗期长,对环境较敏感。3.分株繁殖。此种繁殖方法是目前人工繁育白芨的常规方法。即选当
First, breeding methods 1. Asexual reproduction. Use excavation of wild whitefowl, gradually cultivated through asexual reproduction, the accumulation of seedlings. The disadvantage is the lack of wild resources, the accumulation of large-scale seedlings lead to a longer cycle, and long-term generations of asexual reproduction, there will be degradation of seedlings, reduced disease resistance. 2. Seed breeding. Breeding with Bletilla striata seeds. The disadvantage is that there is no endosperm seeds, short life expectancy, but also on the shade of the higher requirements, it is difficult to shade, the seedling is long, more sensitive to the environment. 3 ramets breeding. This breeding method is currently the conventional method of breeding whitefly. That election
