垂枝杉是杉木的一种优良类型,这种杉木的树干通直圆满,枝条纤细,老枝下垂,树冠窄小,不荫田,能耐瘠薄。但由于资源较少,加之营养生长旺盛,结实量不多,致使大面积造林受到一定影响。为了大量生产垂枝杉的优良苗木,湖北省英山县林科所和科学实验站曾于1978年进行了垂枝杉茎尖培养的初步尝试,我们从1980年开始进行了垂枝杉茎尖培养的研究。本试验用茎尖培养方法获得植株,并对影响茎尖培养的有关因素进行了初步 Weeping fir is a fine type of Chinese fir, the trunk of this fir straight round, slender branches, old branches drooping, narrow crown, not Yau Tin, can be barren. However, due to less resources, combined with vigorous vegetative growth and low yields, large-scale afforestation is affected to a certain extent. In order to mass-produce excellent seedlings of weeping fir, we made a preliminary attempt to cultivate the shoot tip of weeping fir trees in 1978 at the Forestry Branch and Scientific Experiment Station in Yingshan County, Hubei Province. Research in culture. In this experiment, the plantlets were obtained by shoot tip culture method, and the factors affecting the shoot tip culture were preliminarily studied
