欧洲云杉引种试验研究

The Introduction Test of Picea abies

为确定鄂西地区欧洲云杉的适生区域,进行欧洲云杉德国种源引种栽培试验,试验结果表现良好,25 a生林分树高13.2 m,平均胸径19.8 cm,材积0.206 2 m^3,材积比人工林杉木、巴山松、油松提高38.7%-46.9%。海拔区域试验表明6 a生欧洲云杉林分树高生长量在海拔1 060-1 916 m差异不显著,适宜鄂西山区海拔1 500-1 900 m,年降水量1 000mm以上的区域营造工业原料林或种子园。

In order to know the most suitable area for the growth of Picea abies in the west of Hubei Province,we conducted the introduction test of Piceaabiesof German provenance and the experimental result showed that the test tree performed well.The average height,DBH（diameter at breast height）and volume of 25-year-old stand was 13.2 m,19.8cm and 0.206 2 m^3,respectively.Compared with planation of Cunninghamia lanceolata,Pinus henryi and Pinus tabuliformis,the volume of the stand increased by 38.7%-46.9%.The altitude test showed that the difference of the height of 6-year-old Picea abies at the altitude from1 060 m to 1 916 m was not significant,and the area at the altitude from1500 m to 1 900 m and with the annual rainfall of more than1 000 mm was suitable for planting Picea abies to build the industrial material forest or seed orchard.
