细绿萍(A20lla Filiculoides Lank)又名细满江红、蕨状满江红,1977年开始在我国养殖利用,由于它具有高固氮、高光能租高产特性,养殖利用发展迅速,但细绿萍在养用上最大的弱点是萍体耐高温性差,盛夏除了利用冷泉和阴棚能获得小量萍体过夏之外,在自然界生长的萍体均受热害死亡。利用细绿萍有性世代进行孢子果育苗,是生产上急待解决的问题。1978年以来,我们开始观察细绿萍自然结孢特性,研究孢子采集、孢子萌发和幼苗培养等有关问题,初步明确了主要的技术关键,获得了孢子育苗的成功,并在生产上开始应用,现将研究结果综述如下:
A20lla Filiculoides Lank, also known as fine Jiang Hong, fern-like Azolla, began breeding in China in 1977, due to its high nitrogen fixation, high light can be renting high yield characteristics, the rapid development of breeding use, but fine green Ping in the use of The biggest weakness is the poor body temperature tolerance, in addition to the use of cold springs and shady summer can get a small amount of Ping summer, outside, the growth of the body in Ping are subject to heat death. The use of fine Luping sexual generation of spore fruit nursery, is the production of urgent problems to be solved. Since 1978, we have started to observe the natural spore forming characteristics of Spirillum philoxeroides, study the spore collection, spore germination and seedling culture. We have initially identified the key technical issues, obtained the success of spore nursery and started to apply them in production. The research results are summarized as follows:
