南岔林区银中杨引种栽植试验研究

Study on introduction planting experiment of Populus alba×berolinensis in Nancha forest region

银中杨在黑龙江省南岔林区表现了良好的适应性,虽然扦插育苗成活率偏低,但通过覆膜可明显提高成活率;造林成活率与本地乡土树种大青杨无明显差异,而在苗期和造林早期,生长量显著高于大青杨;耐寒、抗病虫害性能与大青杨相当。

Populus alba×berolinensis exhibited excellent adaptability in Nancha forest region. Survival rate of Populus alba×berolinensis was lower by cutting propagation measure in Nancha forest region,but the survival rate could be advanced obviously by film mulching. The difference of planting survival rate was not insignificate between Populus alba×berolinensi and cathay poplar. In the earlier phase and later phase of afforestation,growth of Populus alba×berolinensi was higher than cathay poplar. And the cold tole...
