Abstract: : The characteristics of the lignocellulose degradation were studied during the fermentation of wolfberry branches substrate. By design of orthogonal experiment, wolfberry powder branches and sophora alopecuroides stem powder mixed in ratio of 4∶1 were used to study the influence of fermentative factors on fermentation rotten rate and lignocellulose during the fermentation of wolfberry branches. The results showed that, by the end of the fermentation, the treatment, which the pile body is more branches, the decomposing rate is higher, accelerate the decay of the Chinese wolfberry powder branches on turns heap temperature of 60 ℃, water of 60%,added oil cake and inoculated with coarse cellulose degrading bacteria, promoted the decomposing and pile body, and can shorten the time of wolfberry rotten branches. Temperature, water, nitrogen and exogenous microorganisms had significant or extremely significant effect on the degradation of lignocellulose. Degree of lignocellulose degradation was shown as following order: hemicellulose, cellulose, lignin, the degradation rates of hemicellulose and lignin stayed above 20% and 11%. The treatment, which turns heap temperature of 60 ℃, water of 60%, added oil cake and inoculated with coarse cellulose degrading bacteria,the higher degradation rates of lignocellulose were got, resulting in promoting more effective degradation on organic matter.

Key words: wolfberry branches powder, fermentation factor, the decomposing rate, ignocellulose
