细绿萍又名满江红,是一种固氮能力很强的水生绿肥良种.我所于1978年从江西省农科院引进,通过四年来的试验观察及各地示范推广,都证明细绿萍具有体大、高产、优质、耐寒、耐肥,能湿生,结孢率高而稳定,雌性比例大等优点.它既是好肥料,又是优质的青饲料,还可用作沼气池的发酵原料,在农牧业生产上有着提供“三料”的巨大潜力. 但细绿萍不耐高温,越夏困难.据1979年观察,在自然光照条件下,当水温连续4天在39—41℃时,其伤亡率为42.1%,当水温再连续4天上升到40—43℃时,伤
Fine Green Liping, also known as Man Jiang Hong, is a kind of aquatic green fertilizer with strong nitrogen fixation ability. I was introduced from Jiangxi Provincial Academy of Agricultural Sciences in 1978, and through four years of experimental observation and various local demonstration and promotion, It is both good fertilizer and high quality green feed as well as fermenting raw material for biogas digester. It is widely used in biogas digester The production of agriculture and animal husbandry has the great potential to provide “three materials,” but the fine green Ping is not high temperature, the more difficult the summer.According to the observation in 1979, under natural light conditions, when the water temperature for 4 days in 39-41 ℃ , The casualty rate was 42.1%. When the water temperature rose to 40-43 ° C for another 4 days, it hurt
