Average height 20.32m， average DBH 27.62 cm and average individual volume 0.4951m3 at 19 year-old in Beijing area， the volume is 1.41 times of the control （Chinese white poplar in Yi County）. Wood basic density 0.409g/ cm3， fiber length 1，095μm. The wood is white with straight grains. No moist heart wood， wood turning does not cause rough surface. Up to 19 year-old， basically no blister canker occurred. Resistance to leaf rust and leaf spot diseases is more than 50% stronger than that of the Chinese white poplar in Yi County.
Silvicultural Techniques：
Trees planted at a spacing of 4m by 6m. Planting pits are dug according to the size of seedlings and an appropriate amount of base fertilizer is applied into the pits. Root system should be well maintained during lifting in the nursery. The length of the root system should be longer than 15 cm. Lateral and terminal branches and poor roots should be can be pruned as appropriate. The root system should be kept moist. Seedlings should be planted as soon as possible after lifting from nursery， no later than three days. Trees were irrigated immediately after planting. When buds appear， remove unnecessary ones to ensure a straight and round stem. The seedlings should not be planted near plants of mulberry family. Suitable for farmland shelterbelt forest， street and roadside trees.
