199. 876 t/hm2, 7. 60 t/(hm2. a) and 0.0380 , respectivily of L.gmelinii forest. The biomass, productivity and NP/B of Larix spp. population are 214. 31 t/hm2, 11. 44 t/(hm2. a) and 0. 053 4, respectively of L.principis-rupprechtii population;
Taking the larch plantation'at Laoshan Experimental Station. Maorshan Experimental Forest Farm of Northeast Forestry University as an example. the authors analyzed the effects of different thinning densities on the physical mechanics properties of larch wood.
In our experiments, one-year-old Larix olgensis seedlings were cultivated in sand, and supplied with solutions with different concentrations of nitrate or phosphate.
mongolica, Pinus koraiensis and Larix gmelinii) and natural secondary forests (Fraxinus mandshurica, Quercus mongolica and Populus davidiana).
The results showed that the river flow increased in the initial ten years after forest harvesting, but decreased gradually with the growth and crown closure of the Larix gmelini plantations.
Density structure and growth dynamics of a Larix principis-rupprechtii stand for water conservation in the Wutai Mountain Region
To discover the site adaptability and density suitability of Larix principis-rupprechtii as a water conservation forest in Wutai Mountain, Shanxi Province, the growth process and diameter distribution characteristics of 10-year-old artificial L.
The role of readily hydrolyzable polysaccharides of larch wood in manufacture of board materials
Role of readily hydrolyzable polysaccharides of larch wood in production of board materials is studied.
The quick determination method of resin content in larch wood
The resin content in larch wood is usually determined by the traditional Benzene-Alcohol Extract Method (BAEM).
GCP and APP were used as flame retardants for poplar wood and larch wood, and their flame retardancy(OI), permeability (Surface electron spectroscopy), water-repellency and corrosion toward nail evaluated.
