Abstract:

Took Forsythia mandschurica as experiment material, investigated the effect of the soil under Pinus sylvestris var. mongolica and Picea koraiensis, the garden soil covering deadwoods on Forsythia mandschurica’s growth.. From the perspective of landscape construction, try to selected for the shrubs for growth under the Pinus sylvestris var. mongolica and Picea koraiensis The results showed that: the growths which the soil under Pinus sylvestris var. mongolica and the garden soil covering deadwoods both played no evident role on promoting or inhibit Forsythia mandschurica’s growth, but only on the accumulation of organic matter and chlorophyll’s composed had role in promoting; in addition to the soil under Picea koraiensis promoted the young sprout’s growth and promote the synthesis of chlorophyll b and chlorophyll; the garden soil covering Picea koraiensis deadwoods played no evident role on promoting or inhibit Forsythia mandschurica’s growth.
