Abstract

Abstract: The wood properties of two kinds of eucalyptus, artificial cross (LH1) and free-pollination (U6), were analyzed. Meanwhile, modern fuzzy mathematics theory and modeling method were applied to establish the comprehensive multi-indexes evaluation system of the fast-growing wood. Compared with free-pollination U6, the holocellulose contnet, length-width ratio and basic density of artificial cross LH1 were increased to 82.5%, 42 and 473 kg/m³ from 81.93%, 40 and 441 kg/m³ respectively. Meanwhile, the lignin and pentose contents were decreased to 24.11% and 19.33% from 25.68% and 21.40%, respectively. Based on the analysis of wood properties, it is believed that the pulping adaptability of artificial cross LH1 is better than that of free-pollination U6. Comprehensive evaluation model was established, and it is reliable after comparison with wood properties and prediction. Mechanical pulping properties of artificial cross LH1 located in medium level(level III), while free-pollination U6 was in lower medium level(level IV). With the comprehensive comparison of wood properties and evaluation model, pulping applicability of the LH1 is better than U6.
