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.
通过试验和数据处理,得出了沙柳树皮纤维长度、宽度随平茬和材龄的变化规律,结果表明沙柳树皮长度要比沙柳材的要长,宽度基本相同,沙柳树皮纤维长度主要受平茬次数的影响;找出了沙柳树皮中灰分、冷热水抽出物为、1%NaOH抽出物为,甲苯乙醇抽出物、酸不溶木素与平茬次数和材龄之间的关系,除酸不溶木素外,其他成分均明显高于沙柳材,沙柳树皮的化学成分主要受平茬次数的影响;利用TG和DSC法分析了沙柳树皮和沙柳材的反应热特征,确定了热解的温度范围;研究了沙柳树皮量对于刨花板MOR、MOE、吸水厚度膨胀率、握钉力以及内结合强度的影响,结果证明沙柳树皮量对于刨花板的各项性能指标影响显著,它的掺入降低了刨花板的各项性能;对沙柳树皮板的研究表明,沙柳树皮板的各项性能与同类树皮板的性能基本相近,建立的二次回归模型稳定,并利用回归方程求出了适宜的沙柳树皮板制造工艺。

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.
