河北杨是杨柳科优良品种。耐干旱、瘠薄的土壤,抗病虫害能力强。不受天牛危害,是我国西北地区重要的乡土树种之一。但因繁殖困难,导致种苗供应不足。应用组织培养快繁技术,对河北杨培养基、培养条件和移栽过程进行系统的研究,建立河北杨的组培快繁技术体系,可以提高繁殖速度和移栽成活率,降低成本。对于该树种在本地区的推广具有一定的现实作用。
Hebei Yang is the elite varieties willow. Drought-resistant, barren soil, strong pest resistance. Not be benevolent endangering, is one of the important native tree species in Northwest China. However, breeding difficulties, leading to insufficient supply of seedlings. The tissue culture and propagation technology was used to systematically study the culture medium, culture conditions and transplanting process of Hebei Yang and to establish the tissue culture and propagation technical system of Hebei poplar, which could increase the propagation speed, transplanted survival rate and reduce the cost. The tree species in the promotion of the region has a certain realistic effect.
