满江红又名红萍、绿萍,它既可以做农田绿肥又是畜禽的良好饲料。目前全国已大规模养用。最近国外一些研究机构,如菲律宾的国际水稻研究所也开始了满江红的研究和推广。现存于世界上的满江红的两个亚属六个种在我国都已得到活材料。不论是农业生产还是科学研究,都需要经常保存无病、无虫、健壮的满江红纯种。为此,我们介绍一种行之有效的,简易的保藏满江红种质的方法。具体方法如下: 将生长健壮的满江红植株用自来水冲洗干净,切取距离分枝顶端4—5毫米的切段,每一切段要带有几个茎尖和10—20片幼叶。接着将切段置于小尼龙袋中再用自来水冲洗半小时,然后用2％漂白粉加0.1％中性洗涤剂浸泡2— Azolla, also known as Hongping, Luping, it can do both green manure and livestock and poultry is a good feed. At present, the country has large-scale use. Recently, some foreign research institutes such as the International Rice Research Institute in the Philippines also started research and promotion of Azure. The six species of the two subgenus of the Azolla that are present in the world have all obtained living materials in our country. Whether it is agricultural production or scientific research, we need to regularly save disease-free, insect-free and robust Azolla purebreds. For this reason, we introduce an effective and easy method of preserving Azolla. The specific method is as follows: The growth of robusta plants rinse with tap water, cut from the top of the branches 4-5 mm cut, each cut with several tips and 10-20 young leaves. Then cut into small nylon bags and then washed with tap water for half an hour, and then with 2% bleach plus 0.1% neutral detergent immersion 2-
