‘凤丹’牡丹在福建寿宁的引种试验初报

A preliminary Report on Introduction Experiment of Paeonia ostii in Shouning County

对寿宁不同海拔引种的‘凤丹’牡丹早期生长适应性进行了调查。结果表明,3a‘凤丹’牡丹在寿宁不同引种地生长良好,能开花结实,造林成活率在85%以上,能适应福建寿宁的气候和土壤条件,但树高生长出现了"退梢枯枝"现象,结实率偏低、丰产性表现较差。由于引种的‘凤丹’牡丹尚处于幼龄期,其生长特性及丰产性仍有待于进一步观察,暂不建议大面积栽培与推广。

The early growth adaptability of Paeonia ostii in different altitude regions of Shouning was investigated. The results showed that 3-year-old P. ostii could grow well, blossom and fruit in different areas across Shouning in Fujian province, and its afforestation survival rate was over 85%, which means P. ostii adapted to the climate and soil conditions of Shouning. However, the height growth of P. ostii showed the appearances of ＂degenerated tip and dead branch＂, which led to low seed and poor productivity. However, P. ostii group in Shouning was still in earlier age, and the growth characteristics and high yielding need to be studied further. Therefore, it was recommended that the cultivation area of P. ostii should not be extended.
