不知春而负重拉力强的植物黄檀

The Plant Had Characteristic on Ignorance Spring,High Quality Loading and High Tensile Strength——Dalbergia hupena Hance

不知春植物实为蝶形花科植物黄檀(Dalbergia hupena Hance),因其比常规植物发芽慢,一般要在4月降雨量多后才发芽展叶,故名不知春、望水檀,但它对生长环境要求不严,耐干旱、瘠薄,其木材结构细密,是优质负重力及拉力强的用具材料,木工用的刨刀创身和农人用的扁担及工艺雕刻素材都采用其木材,极有市场价值,是荒山造林、城乡庭园绿化的理想树种。就其形态特征、生长习性、栽培技术、经济价值作一阐述,供同仁参阅。

The ignorance spring plant is Dalbergia hupena Hance belonging to Papilionaceae. In spring season,it slower than conventional plants to germinate and generally sprout leaves in April after rainfall. Thus the name is ignorance spring or Wang Shui Tan too. But it has strong adaptability and resistance to dry and barren. It is a fine wood structure,high quality loading and high tensile strength tool material. Using these woods can be made into knives for woodworking,a shoulder pole for farmers and carving a pole for craft sculpture. It has a great market value,which is ideal for artificial afforestation,rural and urban garden greening tree species. This article focuses on explaining its morphology,growth habit,cultivation techniques,and the economic value,for colleagues to discuss.
