| 摘 要： | 为了合理开发我国西北地区的沙生灌木，研究了内蒙古西部地区沙柳，柠条，沙棘，红柳，桦棒，杨柴６种主要沙生灌木的ｐＨ值，酸碱缓冲容量与ＵＦ胶混合物固化时间。结果表明：６种灌木均呈弱酸性，ｐＨ值为６．０３￣４．５４，酸缓冲容量为０．１０５￣０．０４０ｍｍｏｌ，碱缓冲容量为０．３１４￣０．２２２ｍｍｏｌ。种间的ｐＨ值，缓冲容量和ＵＦ胶固化时间差异显著，而每种灌木部位间的上术指标均无显著差异。

| Abstract: | In order to use shrub materials to produce wood based panels reasonably,pH value,buffering capacity and curing time of 6 main shrub species in the north western China were measured.Testing results indicated that the 6 species showed little acidity with pH values between 6.03 to 4.54,that the alkali buffering capacities were between 0.314 to 0.222 mmol and acid buffering capacities were between 0.105 to 0.040 mmol. |
