(redirected from China-fir)



a genus of evergreen conifers of the family Taxodiaceae. The crown is narrowly pyramidal. The leaves are linear-lanceolate, sharp-pointed, more or less spirally arranged, and shining. The cones are 3–4 cm long, roundish ovate, with greatly reduced seeds; they mature in the first year and do not fall off the tree. The seeds are narrowly winged. There are two known species. Cunninghamia konishil is native to Taiwan. The China fir (C. lanceolata) is widely distributed in the temperate regions of China, where its soft, lightweight, aromatic, and rot-resistant wood is used for buildings and various wood products. The China fir is cultivated as an ornamental on the Black Sea Shore of the Caucasus, where it grows and propagates well.

As shown in Figure 2, the linear fitting curve for China-fir is less steep than the other curves, which are nearly parallel to one another.

Three native wood species, Weeping-willow (Salix babylonica), China-fir (Cunninghamia lanceolata) and Moso-bamboo (Phyllostachys pubescens), were degraded by the white-rot fungus Trametes versicolor B 1.
The native wood species, China-fir (Cunninghamia lanceolata), Moso-bamboo (Phyllostachys pubescens), and Weeping-willow (Salix babylonica) are widely used in the Chinese wood industry.
Three wood species, China-fir (Cunninghamia lanceolata), Weeping-willow (Salix babylonica) and Moso-bamboo (Phyllostachys pubescens), were obtained from Wuhan, China.
Weeping-willow and Moso-bamboo wood exhibited higher weight, lignin and cellulose losses than China-fir wood (Fig.
Although cellulose loss on China-fir wood was significantly lower than other woods, there were no significant differences in total cellulase activities on China-fir, Weeping-willow, and Moso-bamboo woods by the paired t-test on the data from Table 1 at 99 percent confidence level.
The decay resistance of China-fir (Cunninghamia lanceolata) was evaluated in several tests using white- and brown-rot fungi in an American Wood Preservers' Association soil-block test.
China-fir (Cunninghamia lanceolata (Lambert) Hooker) grows at higher elevations in many areas of Southeast Asia, particularly in southern China, Laos, and Vietnam.
While China-fir has a reputation for durability, there are concerns among potential users that this second-growth material may lack the durability of lumber from old-growth trees since there is evidence of this effect in other wood species (Taylor et al.
China-fir lumber was evaluated in three separate tests over a 3-year period.
Moisture levels in the China-fir blocks were not excessive, leading us to include these results in our study.
