Abstract:

Populus deltoides ‘Lux’ × (P. deltoides ‘Shanhaiguan’ × P. simonii) ‘Zhaiguan I’and Populus deltoides ‘Lux’ ×(P. deltoides ‘Shanhaiguan’ × P. simonii)‘Zhaiguan Ⅱ’are elite poplar varieties selected from Populus deltoides ‘Lux’ ×P. ‘Lu6’,‘Lu31’and ‘Lu69’. They are male, and grow fast with the volume close to the control. Their crowns are 1/2-1/3 narrower than wide-crown poplar. They are easy to root, and highly capable of resisting saline-alkali. They grow well in the medium and low saline-alkali soil with 0.3 percent of salinity content and pH 8~8.5. So they are new excellent agroforestry varieties, and suitable for north and eastern northwest China.

Key words: poplar, elite variety, fast growing, narrow crown
