3个油用牡丹栽培品种的适应性分析

The adaptability of three cultivars of oil peony

对‘凤丹’牡丹、‘香丹’牡丹和紫斑牡丹等3个油用牡丹品种在福建闽北地区的适应性进行比较试验,并对其植株性状、果实性状、产籽量及抗病性等进行调查分析。结果表明:‘凤丹’牡丹能适应引种地的气候和土壤条件,幼树长势良好,能正常开花结实,但丰产性表现一般、果实经济性状较好,在闽北高海拔地区可适量推广种植,以满足不同市场需求;‘香丹’牡丹幼树能正常开花结实,果实经济性状一般,丰产性较差,有待于进一步观察研究;紫斑牡丹品种表现较差,幼树能存活,但树体生长基本停滞,开花少,且不结实,不适宜在闽北地区推广种植。

The cultivars of oil peony, i.e., Paeonia ostii ‘Feng Dan’, P. suffruticosa ‘Xiangdan’and P. rockii were introduced and cultivated from 2015 to 2018 in Zhenghe County, Fujian. Their growth characteristics, fruit traits, plant yield and disease resistance were studied. The results showed that Paeonia ostii‘FengDan’adapted to the climate and soil conditions of the high altitude area in Zhenghe County, and grew well with normal blossom and fruits, but showed moderate yield and better economic traits of fruit, which means P. ostii ‘Feng Dan’could be planted appropriately to meet different market demands in the high altitude area of North Fujian. P. suffruticosa ‘Xiangdan’had normal growth and could blossom and fruit, but showed worse productivity and moderate seed oil quality, so it needed further observation and research.P. rockii could survive, but grew poorly, few blossoms and no fruit. Therefore, it was recommended that P. rockii should not be extended in northern Fujian.
