沼气肥是沼气粪水和沼气渣的总称,它们都是沼气发酵的产物,是在厌氧条件下,使农村各种有机肥源经过加工改造形成的优质农家肥料。沼气粪水含有水溶性的有机、无机酸盐类,如铵盐、钾盐、磷酸盐,是一种速效性肥料。沼气粪渣含有较全面的养分和丰富的有机质,其中还有一部分已被改造成腐植酸类物质,是一种缓速兼备又具有改良土壤功效的优质肥料。随着沼气事业的发展,沼气肥种田,养鱼夺得高产已不乏其言谈了。最近,我们调查了大量的沼气肥养鱼的农户,平均亩产鲜鱼325公斤,比非沼气肥养鱼的同类池塘增产
Biogas fertilizer is the general term for biogas manure and biogas residue. All of them are products of biogas fermentation and are high-quality farmhouse fertilizers formed by processing and reforming various organic fertilizer sources in rural areas under anaerobic conditions. Biogas manure contains water-soluble organic and inorganic acid salts such as ammonium salts, potassium salts and phosphates, which are quick-acting fertilizers. Biogas fecal residue contains more comprehensive nutrients and rich organic matter, some of which have been transformed into humic substances, is a slow-paced and has the effect of improving the quality of soil fertilizers. With the development of biogas, biogas fertilizer farming, fish production has no shortage of its own talk. Recently, we investigated a large number of biogas fertilizer fish farmers, the average per mu yield of fresh fish 325 kilograms, than non-biogas fertilizer fish ponds to increase production
