　　将经过预处理的玉米秸秆与猪粪混合，设置3个实验组，分别加入30％，40％和50％的接种物，在中温（35±1℃）、总固体浓度TS为20％的条件下进行厌氧发酵，研究接种量对秸秆猪粪混合厌氧发酵的产气效率、pH值以及甲烷含量的影响。实验结果表明：加入40％的接种物的实验组产气效果良好，总产气量为64445mL，比接种量为30％的实验组高19．1％，且略低于接种量为50％的实验组，平均甲烷含量均高于其它两个实验组；实验初期， pH 值出现一定下降，但很快又恢复至合适水平，整个阶段pH值比较稳定。接种量为40％的实验组的TS产气率、VS 产气率、池容产气率和平均甲烷含量，与30％接种量的实验组差异性显著（ P＜0．05），与50％接种量的实验组差异性不显著（P＞0．05）。综合考虑，40％的接种量是较优的接种物浓度。

In this experiment ,we mixed the pig manure with corn wastes under simple pretreatment , then set them into three same groups and added the inoculum which were 30%, 40%and 50%.The experiment was conducted to investi-gate the effect of inoculum in different mass fractions on gas production efficiency , pH values and methane content during the process of anaerobic fermentation about corn wastes and pig manure , under the condition of 20%mass fraction of to-tal solid, 35℃±1℃.The results showed that , the total gas production with 40%of the inoculum was 61 805 ml, which was 14 .2%higher than the one with 30%of the inoculum ,slightly less than the one with 50%of the inoculum;The pH value fluctuated in initial stage , but it returned to the appropriate levels soon .The pH value was stable in the entire stage.In addition, the average methane content with 40%of the inoculum was higher than other two groups; the differ-ences of TS gas yield , VS gas yield , biogas production and average methane content was significant between 30% and 40%of the inoculum ( P<0 .05 ) .By contrast , the differences was not significant between 40% and 50% of the inocu-lum ( P>0 .05 ) .Comprehensive consideration , 40% of the inoculum is much better .
