Abstract:: Cultivation of Auricularia auricular using two kinds of pruning waste (tea branches and myrica-like mosquitomam branches) as new basal ingredient for substrates was investigated,the yield and quality of Auriculara auricular was determined,the optimum media formula was screened,in order to supply substitution for Auricularia auricular cultivation,and new utilization way for agriculture residues.The results showed that tea branches were very suitable for A.auricular cultivation.When using tea branches alone as main ingredient the yield was the highest,116.48 g per bag,and the yield value gradually reduced along with the decrease of tea branches proportion.Anyway these values were all higher than the control.The yields on substrates prepared by myrica-like mosquitomam branches were all lower when compared with control.But when the proportion of myrica-like mosquitomam branches was 20%,the yield was acceptable.Further more,some physic-chemical properties of A.auricular were also determined in this study.After adding substituting materials,the highest values of crude protein,crude fiber,crude fat,total sugar and total flavones in A.auricular were 190.97,61.40,16.25,490.25,2.47 g·kg-1 respectively.In addition,the microelements and amino acid contents of A.auricular were abundant too.So cultivation of Auricularia auricula with reasonable formula of tea branches and myrica-like mosquitomam branches could promote its high yield and good quality.
