Study on Dyeing Properties of Acid Dyes for Different Tree Species

Use acid scarlet3R ,acid orangeⅡ,acid black ATT and black powder as pigment,prepare for Acid Color, choose four fast growing woods-Chinese fir, poplar, eucalyptus and rubber wood as research objects, study on dyeing properties and dyeing effects of acid dyes for different tree species. It is found, there are differences in staining effects for four fast growing woods. Attachment properties of dyestuff solution on Chinese fir is good, but dyes proportion is very poor; Attachment properties of dyestuff solution on poplar is good, but dyes proportion is very poor; Both attachment property of dyestuff solution and dyes proportion of eucalyptus are not good; Both attachment property of dyestuff solution and dyes proportion of rubber wood are good.

Stand Growth

Abstract The self-thinning rule has played a critical role in controlling stand stocking and modeling stand development in forest stands. Chinese fir (Cunninghamia lanceolata) is a native and fast-growing tree species used for timber production and is widely grown in southern China. Effective management of this important tree species requires accurate and reasonable predictions of stand growth and survival. Remeasured data from 48 plots distributed in Fujian, Jiangxi, Guangxi, and Sichuan provinces were used to develop models to predict stand survival and basal area based on the self-thinning trajectories. These trajectories were constructed using a self-thinning slope of –1.605, as suggested by Reineke (1933) (Method 1), and the slopes estimated either from two groups of sites (Method 2) or from climate variables (Method 3). Results indicated that the stand growth and survival models using Method 3 performed best, followed by Method 2 and Method 1. In addition, stand growth and survival curves predicted from Method 3 were more similar in shape to those from the observed values, as compared with Method 1. Overall, the models based on the self-thinning lines using climate-sensitive slopes provided reasonable predictions of the stand development dynamics. Therefore, these results facilitate modeling of the relation between stand growth/survival and self-thinning under climate change.
