Influence of different site conditions on the wood physical properties of Alnus formosana
摘要
Abstract
The physical properties of six-year-old Alnus formosana collected from four standard testing grounds of Leshan and Guangyuan city in Sichuan Province were tested, and meteorological data in recent five years and soil samples of these places in which Alnus formosana grown were collected. The major correlation factors influencing the properties of Alnus formosana were explored using correlation analysis method. Results indicated that the differences of the physical properties of Alnus formosana from different site conditions were significant; canonical correlation existed between site conditions, and physical properties, contents of N, P, K, pH of soil, annual rainfall, sunshine duration and altitude were the main factors. The quality of Alnus formosana im proved with the increase of the contents of slowly available K and total N and the reduction of the content of total P. The raise of the content of total K and available P, pH, sunshine duration, and the decrease of annual rainfall enhanced the shrinkage of timber and the basic density of Alnus formosana. The air-dry density and volume and , tangential shrinkage of oven-dried Alnus formosana which planted in lower altitudes decreased, and basic density increased at the same time.关键词
