Abstract：In order to promote the recycling utilization of waste litters , five kinds of litters for the fermen-tation beds were designed in this experiment .The control one was the mixture of sawdust , rice husk and corn powder, and the others were added with Flammulina velutipe or Pleurotus eryngii residues at the proportion of 15%or 45%to replace the equal amount of sawdust .After pig feeding on the five kinds of fermentation beds for 100 days, the chemical compositions of the waste litters were determined , and the effects of 0, 50 and 100 times of their extracts on wheat germination rate , main root length and activities of SOD , POD and CAT were studied.The results showed that the contents of nitrogen , phosphorus, potassium, copper, iron, zinc, manga-nese in the five waste litters were in a reasonable interval;the wheat seed germination rates were 100%on the second day ( P>0 .05 ) .The main root length and the activities of SOD , POD and CAT in 0 time extract were significantly higher than those in 100 times one(P<0.01).The germination rate, root length and activities of SOD, POD and CAT had no significant differences between the five waste litters at the same time (P>0.05). In conclusion , using 15%or 45%of Flammulina velitupe or Pleurotus eryngii residues to replace the equal a-mount of sawdust in control fermentation bed had no negative effect on the seed germination of wheat .
