不同土壤处理对东北连翘生长影响的研究

Effects of different Soil Treatments on Growth of Forsythia mandschurica

以东北连翘盆栽苗为试验材料,研究樟子松、红皮云杉纯林下土、枯枝落叶覆盖园土处理对东北连翘生长的影响。旨在从园林景观建设的角度考虑,尝试研究筛选出适合樟子松、红皮云杉林下生长的灌木,为丰富松科植物林下园林景观配置提供参考。研究结果表明:樟子松林下土、枯枝落叶覆盖园土对东北连翘的生长都无明显的促进作用或抑制作用,对有机物的积累和叶绿素的合成有促进作用;红皮云杉林下土对新梢的加粗生长有促进作用,促进叶绿素b和总叶绿素的合成;红皮云杉枯枝落叶覆盖园土对东北连翘的生长无明显的促进作用或抑制作用。

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.
