摘　　要：文章通过设计不同投料量的玉米秸秆发酵和粪便发酵的产气率和产气量对比试验,认为在一定条件下,增加玉米秸秆的投入量不会增加沼气的产气量,反而会下降.但玉米秸秆发酵产生的沼气比粪便发酵产生的沼气热值高.豫北地区沼气池产气高峰期均集中在4～11月份.如果采用一定的保温措施,豫北地区可全年使用沼气.Biogas production rate and the biogas yield of corn straw fermentation digester were compared with manure digester. The result showed that under certain condition, increasing straw inputs would not increase the biogas preduction, instead,it might fall, but the calorific value of corn stalk fermentation bioges was higher than the biogas from manure fermentation. The biogas digester in the North Henun mainly produce biogas duing the April to November. By adopting a certain measures of heat insulation, the digester in the North Henan could work all year round.
