摘要
为丰富河西走廊张掖市城市绿化彩叶树种资源,从辽宁铁岭引种密枝红叶李、红叶李、太阳李、紫叶矮樱4个彩叶树种,对其生长情况、叶色物候期、抗逆性进行观测和评价。结果表明,4个彩叶树种的引种成活率为 81%~100%;地径、树高、冠幅年均生长量分别为2.18~2.82 cm、72.21~96.69 cm、58.34~89.29 cm;色叶最佳观赏期为163~170 d,色叶期为163~186 d;抗逆性由强到弱次序为紫叶矮樱、太阳李、密枝红叶李、红叶李。4 个彩叶树种中紫叶矮樱、太阳李、密枝红叶李在内陆河流域甘肃省张掖市综合生长表现较好,适应性较强,适宜在张掖市园林中广泛推广和应用。
In order to enrich the resources of urban greening tree species in Zhangye city, Hexi Corridor, we observed and evaluated the growth, leaf color phenology, and stress resistance of four kinds of color-leaf species introduced from Tieling of Liaoning province, which are Prunus cerasifera f. atropurpurea ‘Russia’, Prunus cerasifera f. atropurpurea, Prunus cerasifera ‘Pissardii’, and Prunus×cistena ‘Pissardii’. The results showed that the survival rate of the four species of color-leaf tree species was 81%-100%;the annual growth of ground diameter,tree height and crown width were 2.18-2.82 cm,72.21-96.69 cm and 58.34-89.23 cm,respectively;The best viewing period is 163-170 days,and the color-leaf period is 163-186 days;The decreasing order of resistance is:Prunus×cistena‘Pissardii’,Prunus cerasifera ‘Pissardii’,Prunus cerasiferaf.atropurpurea‘Russia’,and Prunus cerasifera f.atropurpurea.Among the four species of colorful leaf trees,Prunus×cistena ‘Pissardii’,Prunus cerasifera ‘Pissardii’,and Prunus cerasiferaf.atropurpurea ‘Russia’have good comprehensive growth performance and strong adaptability in the inland river basin of Zhangye city,Gansu province,therefore they are suitable for wide application and application in Zhangye city gardens.
