【 摘 要 】

This research used manihot esculenta crantz of 8-10 months old, eucalyptus and acacia mangium wood of 5-year-old. The active alkali (AA) charge variations of 16% to 20% with 1% intervals. The sample position of composition of manihot esculenta crantz wood was 0-22 cm above ground level. The density of manihot esculenta crantz, eucalyptus and acacia mangium were 480 g/cm3, 483 g/cm3 and 499 g/cm3, respectively. Base on FTIR analysis, have the same dominant functional groups. The average total yield manihot esculenta crantz were lower than eucalyptus or acacia mangium of 12.422% and 24.92% respectively and screen yield manihot esculenta crantz were lower than eucalyptus or acacia mangium of 13.678% and 26.85% respectively. Each AA charge increase of 1% in manihot esculenta crantz, eucalyptus and acacia mangium can decrease the total yield by 0.635%, 0.803% and 1.14%, the screen yield decreased by 0.543%, 0.563% and 2.196% respectively. The mean of KaNo difference of manihot esculenta crantz higher than eucalyptus or acacia mangium of 7.038 and 5.236 respectively. Each 1% increase in AA charge may decrease the average KaNo of manihot esculenta crantz, eucalyptus and acacia mangium were 7.693%, 3.778% and 6.628% also decreased viscosity by 3.70%, 2.99% and 0.974% respectively.
