摘要:

以60个黑杨杂种候选新品系为试验材料,108杨为对照,在北京进行苗期测定,辽宁凌海,山东诸城、鄄城、宁阳、莒县等地多点田间测试,结合抗病性、木材品质、纸浆造纸性能和养分利用效率等性状的综合评价,最终获得‘渤丰1号’杨和‘渤丰2号’杨2个优良纸浆材良种。在辽宁凌海,6年生‘渤丰1号’杨平均单株材积达0.348 7 m3,“渤丰2号”杨平均单株材积达0.323 9 m3,分别超过108杨(0.282 3 m3)23.52%和14.73%。同时该品种还具有抗病能力强、材质优良、氮素养分利用高效、适应性广等特点,是适合于我国环渤海湾区域内推广应用的高效高产优质欧美杨优良纸浆材新品种。

Abstract:

In this study, 60 hybrid clones of Section Airgeiros were used as plant material and I-108(Populus×euramericana‘Guarien’) was the control, combining with the disease resistance, wood and pulping properties, nutrition using efficiency, and the growth testing in seedling in Beijing and multi-regional trials in different ecological areas, such as Linghai of Liaoning Province, Zhucheng,Juancheng,Ninyang and Juxian of Shandong Province, two new pulpwood varieties P.×euramericana cl.‘Bofeng 1’and‘Bofeng 2’were selected. The mean individual volume of‘Bofeng 1’and‘Bofeng 2’were 0.348 7 m3 and 0.323 9 m3 at the age of 6 years in Linghai, Liaoning Province, the growth rate were respectively 23.52% & 14.73% higher than CK I-108(0.282 3 m3). Both the new selected varieties had the characteristics of fast growing, high disease resistance, good wood properties, high nitrogen using efficiency and wide-ranging adaptability. As the new poplar varieties for pulp wood,‘Bofeng 1’and ‘Bofeng 2’are especially suitable to plant in the region around the Bohai Bay in northeast China.
