毛白杨是一个很好的绿化树种,各地都在尽力发展.但毛白杨的生根能力较差,用常规方法培育,成活率较低;用一般嫁接方法,需要通过培育砧木、嫁接及接穗成活后的管理等工序,不仅生产周期较长,且管理费工,成活率还不理想.为缩短毛白杨培育周期,提高苗圃地利用率,降低育苗成本,河北省涿鹿县林业局苗圃采用快速育苗技术培育毛白杨,实现了两年出圃、苗木质量优良、经济效益高的目的.现将做法介绍给大家.
Populus tomentosa is a good afforestation species, all over the world are trying their best to develop.But Populus tomentosa rooting ability is poor, using conventional methods to cultivate, the survival rate is low; with the general method of grafting, need to cultivate rootstocks, grafting and scion survival Of the management process, not only longer production cycle, and management fees, survival rate is not ideal .In order to shorten the cultivation period of Populus to improve the utilization rate of nursery and reduce the cost of nursery, Zhuolu Forestry Bureau of Hebei Province, nursery using rapid nursery Technology to cultivate poplar, to achieve two years out nursery, nursery stock of good quality, high economic efficiency purposes now introduce the practice to everyone.
