Research on the Model of Fungus Decomposition Rate of Wood Fiber Based on Principal Component Analysis Algorithm

Abstract

Regarding the lignin fiber decomposition rate under the interaction of multiple fungi in the short term, was simplified as the interaction of two bacteria without the influence of external regulation, based on the two shapes of growth rate and moisture tolerance. Based on the growth rate data of fungal pair interaction, the decomposition rate model of lignin fiber based on principal component analysis was established, and the contribution ranking of fungi to decomposition rate was obtained. Then the moisture tolerance data were fitted to find the difference between the water niche width and the competition ranking of fungi. Based on the ranking of the two traits, a linear weighting equation was established, and the cumulative decomposition rate of the interaction between various bacteria was finally obtained to be1298.7.
