通过研究淹水程度对滩地枫杨木材化学性质的影响 ,以期全面了解滩地主要造林树种的化学性质 ,提出合理的定向培育技术及进一步综合利用措施 .研究结果表明 :滩地枫杨木材的 p H值均小于 6.5 ,属于酸性木材 ,第一、二组木材的 p H值分别为 5 .41和 5 .0 0 ,在 0 .0 5水平上差异显著 .除碱性缓冲容量外 ,第二组木材的酸性缓冲容量、总缓冲容量以及每降低 1p H值消耗的 HC1量均比第一组高 .淹水程度对滩地枫杨木材纤素含量几乎无影响 ,其值均为 45 .2 %左右 ;但第一、二组的半纤维素分别为 14 .0 4%和19.5 0 % ,增加了 3 8.9% ;第一、二组的木质素含量分别为 19.9%和 2 0 .6% ,增加了 3 .5 % .
By studying the effect of flooding on the chemical properties of Pterocarysticodorps rugulifera, aiming at a comprehensive understanding of the chemical properties of the major afforestation species in the beach, a reasonable directional cultivation technology and further comprehensive utilization measures were put forward.The results showed that the p H value Are less than 6.5, belonging to acidic wood, the first and second groups of wood p H values were 5.41 and 5.0, significant difference in the level of 0 0 05. In addition to the alkaline buffer capacity, the second group of wood The total buffer capacity and the amount of HC1 consumed for every 1 p H decrease were higher than those in the first group.The degree of flooding had no effect on the wood fiber content of Pterocarya stenophylla, which was about 45.2% However, the hemicelluloses in the first and second groups were 14.04% and 19.5%, respectively, an increase of 8.99%. The lignin contents of the first and second groups were 19.9% and 20.6% respectively, increased 3.5%.
