青海杨扦插育苗技术

经过两年的田间实验，对青海杨扦插育苗技术中的整地与施肥、种条选择与插穗制备、扦插技术与田间管理等技术环节积累了比较成熟的经验，使无芽硬枝插穗扦插成活率达到76％，一年生苗高达到131cm；有芽种条扦插成活率达到93％，一年生苗高达到148cm，为开发利用这一乡土杨树资源提供了依据。

Technique on Cutting Propagation of Populus praewaiskii

After two years of field experiments on soil preparation,fertilization,species selection,cuttings preparation,cutting techniques and field management and other technical aspects are accumulated more mature experience,so that no bud hard branch cuttings survival rate 76%,a year seedling height reached 131cm;the bud kinds cutting survival rate of 93% year seedling height to 148cm,provides a basis for the development and utilization of the native poplar resources.
