目前大田养殖红萍仍沿用无性繁殖,即通过萍母田以营养体养殖方式保种繁种。而用红萍孢子果繁殖有性苗保种繁种的方式(有性繁殖),对于解决萍种越夏和越冬问题具有更突出的优点。对研究红萍繁种工厂化的可行性也是一个值得注意的途径。红萍有性繁殖的研究,近年来已为国内外的科学工作者所重视。但已往生产上使用的萍种结孢率十分低,雌雄孢子果比例小,故红萍有性繁殖方式难以应用于生产。
At present, there is still asexual reproduction of red cedar farming in the field. However, the method of breeding sexual seedlings with sexual seedling with sexual spores by means of Sphagnum sp. (Sexual reproduction) has more prominent advantages for solving the problem of overwintering and overwintering species. It is also a noteworthy way to study the feasibility of multi-species plantation. In recent years, the research on sexual reproduction of Hongping has been paid great attention to by scientists at home and abroad. However, the past production rate of coccidiosis is very low, the proportion of male and female spores is small, so it is difficult to apply sexual reproduction of Hongping.
