苧麻的繁殖方法,分无性繁殖和有性(即种子)繁殖两类。无性繁殖中又分种根、分株、压条和插条四种。老麻区发展苧麻主要采用种根繁殖,近年来巳推广分株(主要利用脚麻)繁殖。这两种繁殖方法的优点是操作简便,能保持品种优良性状;缺点是种根和茎株来源有限,发展速度慢,包装运输困难,还容易传播病虫害。为了解决以上问题,新区发展苧麻可采用种子繁殖。因这种繁殖系数高,包装运输简便,成本低,又无传播病虫害危险。但种子多由老麻区群体品体留种,有性繁殖又
Ramie breeding methods, sub-vegetative and sexual (ie, seed) breeding two categories. Asexual reproduction in the sub-root, ramets, battens and cuttings four. The development of ramie in the old area mainly uses seed multiplication. In recent years, ramie has been propagated in ramets (mainly using the hemp) to breed. The advantages of these two breeding methods are that they are easy to operate and can maintain good traits. The disadvantages are the limited sources of stems and stems, slow development, difficult packaging and transportation, and easy transmission of pests and diseases. In order to solve the above problems, the development of ramie new area can be used for seed breeding. Due to the high multiplication coefficient, the packaging and transportation are simple, the cost is low, and there is no danger of transmitting pests and diseases. However, the seeds and seeds from the old area to stay species, breeding and sex
