摘 要:对湖南翅荚木人工林进行了生长测定。结果表明:翅荚木在湖南丘陵红壤土年均胸径生长量可达2.0cm以上,年均树高生长量可达1.5m以上,蓄积年生长量为16.1m3/hm2以上。对翅荚木材性进行了分析与比较,木材密度为0.314g/cm3,5a生翅荚木纤维长度1010μm,纤维宽度19.6μm,纤维长宽比为52。其木材材性与杨树、桉树相比十分接近。因此,翅荚木是一优质纸浆原料。由于其生长快,又可作为胶合板、家具用材定向培育。提出了相应的苗木培育与造林技术,并建议今后加强翅荚木优树选择、子代测定、良种基地建设等遗传改良的力度,加强其栽培技术研究,为我省营造翅荚木人工林提供技术支撑。The research was based on the growth determination of rare growth rapid growing species of Zenia insignis Chun plantation in Hunan province, The results showed that: the average growth of diameter breast height was over 2.0 cm per year in red soil in hills of Hunan province, the average growth of height was over 1.5 m per year, the amount of growing stock was over 16.1 m^3/hm^2 . Based on tire analysis and comparison of the chamctristics of Z. insigmis Chun, the results showed that : the density of wood was 0. 314 g/cm^3 , the fibre length of five-year old Z. insignis Chun was 1 010μn and the width of fibre was 19.6μn, the aspect ratio was 52.The wood characteristics of Z. insigrds Chun is a high quality paper pulp material. It can be directive breed for veneer and furniture. The technology of breeding and plantation culture were examined. The heredity genetic improvement of superior trees selection and filial generation determination, construction of free breed should be strengthened along with plantingteehnology. Z. insignis Chun is a growth rapid growing species for plantation in Hunan province by strengthen tire study of planting technology.
