The paper carries on qualitative analysis to the acetone extractives before and after discoloring, shows the main components of the extractives and then takes comparison. The results shows :①The hydroxyl is oxidized and then shifted to the carbonyl,carboxyl, ester and ketone groups during inducing discoloration under the pretreatment conditions,which makes the wood color deep;② There are plenty of auxochromic groups in the acetone extractives of silver chain, the interaction between the auxochromic groups and the chromophoric groups makes the wood color deep.

Through research and analysis of data, it was observed that the length and width of bark fiber varied according to the lop and age, the results show the fiber of the Salix bark is longer than the Salix and width of fiber almost same, fiber length of the Salix bark mainly influenced by the times of lop. The ash in Salix bark,1% Sodium Hydroxide Solubility in Salix bark, water solubility in Salix bark, Ethanol-Toluene in Salix bark, acid-insoluble lignin in Salix bark changed with the lop and age is also been investigated, the component of Salix bark is higher than Salix except acid-insoluble lignin,and it's high effected by times of lop; the TG analysis and DSC analysis is been used on the Salix bark and Salix to study the character of the hot-action, and the rang of the pyrogenate temperature is confirm; the quantity of Salix bark effect on the MOR, MOE, swelling in 24h water, nail withdraw and inner strength was determined, the results show that the Salix bark notability effect on the properties of board and dropped it; the properties of the Salix bark board is nearly the board product by other bark residues, it was established the multi regression equation of each properties and optimized the fitting produce condition of Salix bark board.
