马鞭草科植物石梓,是优良速生的亚热带用材树种。本地土名铁骨梧桐。与云南石梓、海南石梓相比,闽北所见之石梓,叶形、长度不同,且耐寒、材质更坚硬。它是国家重点保护树种,是高级家具,室内装饰、造船等的一级用材。石梓分布局限,在我省仅零星分布于南平、建瓯、顺昌、沙县及武夷山一带400—800米的疏林中,闽南华安亦少量分布,且被乱伐几濒于绝迹。它的种子育苗较难出苗。为了扩大苗木繁育系数,发展珍稀树种。我场去年用嫩枝少量扦插可以成活。今年三月中旬。经过扦插试验,蛭石床成活率可达89.5%,育苗也取得了成功。七月初翻床,生根的扦插苗移植圃地,十一月中旬调查(生长期8个月),苗木平均高77.99厘米;平均径粗1.24厘米,平均冠幅72.4×45.7厘米,生长优良。
Verbenaceae Shi Zi, is an excellent fast-growing subtropical timber species. Local native name Iron Plank. Compared with ShiZi of Yunnan and ShiZi of Hainan, ShiZi, which is seen in northern Fujian, has different leaf shape and length, and is hardy and harder in material. It is a national key protected species, is a high-level furniture, interior decoration, shipbuilding and other timber. Shizi distribution is limited in sparsely distributed in our province in Nanping, Jian’ou, Shunchang, Shaxian and Wuyishan 400-800 meters of sparse forests, the southern Fujian Huaan is also a small amount of distribution, and was nearly felled extinct. Its seed nursery is more difficult to emerge. In order to expand nursery stock breeding coefficient, the development of rare species. My field last year with a small amount of cuttings can survive. In mid-March this year. After cutting test, vermiculite bed survival rate of up to 89.5%, nursery has also been successful. Early July overturning bed, rooting cuttings transplant nursery, survey in mid-November (growth period of 8 months), the average seedling height of 77.99 cm; average diameter of 1.24 cm, the average crown of 72.4 × 45.7 cm, good growth.
