红萍繁殖方法有无性和有性繁殖两种。目前生产上主要是利用红萍的无性繁殖。对于有性繁殖,国内外对孢子果的形态、形成过程及孢子果萌发等方面研究较多,但对孢子果形成的条件至今尚无进行系统的观察研究。1978年3—7月,我们与广东省农科院协作对我县红萍研究所红萍大量形成孢子果的主要原因作了调查研究,并初步探讨了孢子果形成与萍种和温、光、营养等因素的关系,现将研究结果总结如下。
There are two methods of sexual reproduction in sexual reproduction. The current production is mainly the use of red asexual reproduction. For sexual reproduction, domestic and foreign research on the morphology, formation process and spore germination of sporophyte is more. However, no systematic observation has been done on the conditions for sporulation. From March to July 1978, we investigated the main reasons for spore fruit formation in Hongping Hongping Institute in collaboration with Guangdong Academy of Agricultural Sciences. We also discussed the formation of spore fruit, , Nutrition and other factors, the results are summarized as follows.
