为探索云南滇中高原黑荆树引种适应性和对土壤肥力的生长响应,对南非种源与澳大利亚种源的生长进行对比,并对南非种源黑荆树的施肥效应进行研究。结果表明,南非种源黑荆树引种至云南滇中高原后,株高、地径、胸径、冠幅等生长调查指标明显优于已引进的澳大利亚种源,林内植株生长性状表现一致,未出现早花早实现象,表现出良好的生态适应性。南非种源幼树不同生长调查指标对施肥处理响应不同,胸径对少量施肥并不敏感;但随着施肥量的增加,不同施肥处理间差异显著,肥料对南非种源黑荆树的生长有明显的促进作用,施肥是黑荆树丰产栽培的重要技术措施。
In order to explore the introduction adaptability of A. striata and the growth response to soil fertility in the Yunnan-Yunnan Plateau, the comparison of the provenances between South African provenances and Australian provenances was carried out. The effects of fertilization on the provenance of the black wattle of South Africa were studied. The results showed that the index of plant height, diameter, diameter at breast height and crown width were significantly better than those of the introduced Australian provenance after introduction of the provenance of Wattle black wattle in Yunnan to the Central Yunnan Plateau. As early as early flowers like flowers, showing good ecological adaptability. South African provenance saplings of different growth indicators of different responses to fertilization treatment, DBH is not sensitive to small amounts of fertilization; but with the increase of fertilizer, fertilizer treatment significantly different between the different fertilizers on the provenance of South African provenance Of the promotion role, fertilization is an important technical measure of high yielding black wattle cultivation.
