檫树(Sassafras tzumu Hemsl)是我国南方主要用材树种之一,生长快,材质好,用途广,深受群众欢迎。七十年代以来,在我省丘陵地区发展很快,目前造林面积约200万亩。檫树属中亚热带树种,主要分布在温暖湿润、雨量充沛的南方十三省区。地理分布范围是北纬23°-32°,东经102°-122°。垂直分布一般在海拔800米以下,山区丘陵,但在群山之中,高达1800米生长仍然良好。多系天然散生林,常与马尾松、杉木、油茶、毛竹、樟树、苦槠、圆槠等树种混生。对土壤物理性能要求较高,最适宜在土层深厚、疏松、湿润、通气、排水良好的酸性土壤上生长,特别是在填方的堆积土壤上生长更好。
Sassafras tzumu Hemsl (Sassafras tzumu Hemsl) is one of the main timber species in South China. It grows fast, the material is good, the use is wide, and it is well received by the public. Since the seventies, in the hilly areas of our province developed rapidly, the current afforestation area of about 2000000 acres. Castanopsis is a subtropical tree species, mainly distributed in the warm humid, abundant rainfall in the thirteen provinces and autonomous regions. The geographical distribution range is 23 ° -32 ° north latitude and 102 ° -122 ° longitude. Vertical distribution generally at an altitude of 800 meters below the mountain hills, but among the mountains, up to 1,800 meters growth is still good. More natural saplings of natural forests, often with Masson, fir, Camellia oleifera, bamboo, camphor tree, bitter gourd, Yuan Shui and other tree species mixed. The physical requirements of the soil is high, the most suitable for the soil deep, loose, moist, aerated, well drained acid soil growth, especially in the packing of the soil to grow better.
