红萍是一种固氮能力强、繁殖快、产量高的优质水生绿肥和饲料。在我省养殖利用中,由于采用红萍的萍体保种,终年生长在田间,寒冬的连续冰冻和酷夏的持续高温,常常造成萍体大量死亡,加之,越冬越夏的时间又长,困难多,萍种生产不稳定,给红萍生产的进一步发展,带来一定的困难。为了 Hongping is a nitrogen-fixing ability, rapid propagation, high-yield high-quality aquatic green manure and feed. In our province’s farming and utilization, due to the use of Pingping Pingping species, year-round growth in the field, continuous freezing cold and cool summer continued high temperatures, often resulting in a large number of death Ping, coupled with the winter over the summer time is long, Difficulties, Ping production instability, to the further development of Hongping production, bring some difficulties. in order to
