细绿萍又称蕨状满江红,是一种水生植物。它具有耐低温,易养殖,繁殖快,生物固氮能力强等优点。而且它的蛋白质,粗脂肪等含量都很丰富,既是农作物的好肥料,又是牲畜很好的青饲料。同时也可作为沼气发酵原料。根据各地试验结果来看,细绿萍发酵产沼气效果甚好,每公斤细绿萍干物质可生产沼气0.12～0.21米~3,沼气池投入鲜萍5000～7000斤半个月后便可供气使用,能满足五口之家农户日烧三餐持续二个半月。新昌县沼气试验站2.5米~3沼气池放入3000斤鲜萍,加100斤按种物,投料后10—20天就大量产气,产气高峰可持续40～50天,发酵150天,总产气量达22.58米~3,甲烷含量均在54％以上。应用细绿萍作为沼气发酵原料,产气快,时间集中,只要注意调节酸碱度,并及时少加料,就能维持较长的产气盛
Fine green Ping, also known as fern-like river, is a kind of aquatic plants. It has the advantages of low temperature resistance, easy breeding, fast propagation and strong biological nitrogen fixation. And its protein, crude fat and other content is very rich, both a good fertilizer for crops, but also a good livestock green feed. Biogas fermentation can also be used as raw materials. According to the results of the test, the production of biogas by Fine Green Luping is very good. The biogas produced per kilogram of fine green Pingpian can produce biogas 0.12 ~ 0.21 m ~ 3. Gas use, to meet the family of five farmers burned meals for two and a half months. Xinchang County biogas pilot station 2.5 m ~ 3 digester into the 3000 pounds of fresh Ping, plus 100 pounds according to species, 10-20 days after feeding a large number of gas, gas peak sustainable 40 to 50 days, 150 days fermentation , Total gas production of 22.58 m ~ 3, methane content of more than 54%. Application of fine green as biogas fermentation raw materials, gas production fast, time-focused, as long as the attention to regulating pH, and less feeding in time, we can maintain a longer gas production Sheng
