为给冀西太行山增添优良速生用材树种,笔者自1982～1991年连续10年,在邯郸地区武安市中、低山进行了华北落叶松育苗造林试验。结果表明,根据华北落叶松生物学特性,选择适宜的立地条件,改进技术措施,人为创造适宜环境,华北落叶松能在冀西太行山海拔700～950m,气候干热的中低山区良好生长。1a生幼林树高可达6.27m,5～10a生每年平均高生长0.86m,胸径7.76cm,材积50.625m~3·hm~(-2).比太行山北段驼梁山华北落叶松天然分布区纬度降低2°,海拔降低550～800 m,为低纬度、低海拔地区营造华北落叶松林提供了依据。
In order to add excellent species of rapid growing timber to Taihang Mountain in west Hebei Province, the authors conducted the experiment of afforestation of Larix principis-rupprechtii in middle and low mountains of Wuan City in Handan Region for 10 consecutive years from 1982 to 1991. The results showed that according to the biological characteristics of Larix principis-rupprechtii, selecting suitable site conditions, improving technical measures and creating suitable environment artificially, Larix principis-rupprechtii could grow well in the middle and low mountain areas with an altitude of 700-950 m at the Taihang Mountains in western Hebei Province. The height of tree in young 1a was up to 6.27m, and the average annual growth was 0.86m, the diameter at breast height was 7.76cm and the volume was 50.625m ~ 3 · hm -2 in 5 ~ 10a years than in natural distribution area of Larix principis-rupprechtii The latitude decreases by 2 ° and the elevation decreases by 550 ~ 800 m, which provides the basis for the construction of Larix principis-rupprechtii in low latitudes and at low altitudes.
