【摘要】 <正> 近年来国内外有关报道,从合理开发山地,保护生态环境,寻找优良生物能源出发,开始注意沼气发酵原料植物问题。美国的米利恩(D.L.Million)等人,提出了种植陆上沼气发酵能源作物的设想,密苏里大学正在筛选这类作物,但尚未见到详细报道。在我国有些沼气已经普及的地区,由于原料不足,管理不善,导致沼气池产气率不高,仍然是一个比较普遍存在的问题。我们从绿肥植物着手,寻找比较适应我国情况的沼气原料植物。更多还原

【Abstract】 From the authors experiment and the bibliography cited, the following conclusion may be accepted:The methane fermentation test showed that seven fresh green plants gathered from the Kunming Mountain are better than dry plants. The methane output of the green manure is about 23% above that of others.On the other hand, in hilly area the methane harvest of Gramineae is nearly 13% higher than that of Leguininosea. However,the wild grasses are proved to be better than others. Therefore, it ;s very important to make use of fresh green manure for saving on energy source.更多还原
