红杉（Seguoia Sempervirens〈Lamb〉 EndⅠ.）系最古老的树种之一,原产于美国西部太平洋沿岸,从俄勒冈州西南的切特戈河流域到加利福尼亚洲的马丁角,主要生长在沿海一带,垂直分布高达海拔700-1000公尺。该地冬季多雨,夏季多雾,水分充沛,是红杉生存的有利条件。红杉要求排水良好,土层深厚和湿热气候,但可耐-10℃短期低温。 红杉为常绿乔木,耐阴性强,病虫害少,生长迅速,在原产地40年生优良单株高达30公尺,胸径达90厘米,木材品质优良,用途很广,轻软而致密,比重为0.42,易于加工,油漆性能好、有光泽、耐腐朽,木材红色可代替红木,作室内装饰之用。 红杉易萌芽更新,故除种子繁育外,亦可用杆插繁育。
Sequoia Sempervirens End I. is one of the oldest tree species, native to the Pacific coast of the western United States, from the Chettino River basin in the southwest of Oregon to Martin Point in California, and grows mainly along the coast, Vertical distribution of up to 700-1000 meters above sea level. The winter rainy summer foggy, abundant water, is the favorable conditions for the survival of Sequoia. Sequoia requires good drainage, deep soil and hot and humid climate, but can withstand -10 ℃ short-term low temperature. Sequoia is evergreen trees, strong negative resistance, less pests and diseases, rapid growth, 40 years in the origin of fine single plant up to 30 meters, diameter of 90 cm, wood quality, use a wide range of soft, light and dense, the proportion of 0.42, easy to process, paint performance, shiny, decay resistance, wood red instead of mahogany, for interior use. Sequoia easy buds update, so in addition to seed breeding, but also can be inserted pole breeding.
