中文摘要:
      通过盆栽试验,利用分室隔网培养方法,模拟研究接种丛枝菌根真菌(AMF)对玉米–续断菊(Sonchus asper L. Hill)间作体系Cd吸收和累积的影响。结果表明:①无论Cd添加到A室还是B室,玉米的侵染率都要比续断菊高出6.3% ~ 38.35%。接种AMF之后,都不同程度地提高了玉米和续断菊的生物量,但对玉米和续断菊吸收Cd的影响有所不同。②Cd添加到A或者B室,AMF均会促进该侧植物对Cd的吸收,降低另一侧植物对Cd的吸收。③接种AMF后,续断菊对Cd的转运系数降低,玉米对Cd的转运系数有的升高有的降低。总之,AMF改变了间作条件下玉米和续断菊对Cd的吸收,菌丝在两者之间可能起着非常重要的作用。
Abstract:
      Pot experiment was carried out to simulate the effects of arbuscular mycorrhizal fungi (AMF) on Cd absorption by maize and Sonchus asper L. Hill through compartmentation cultivation system. The results indicated that: 1) In both situations (Room A or Room B) after Cd addition higher infection rate was occurred by maize (6.3% – 38.35%) comparing to those of S. asper. Furthermore, AMF inoculation led to an increase in both maize and S. asper biomass. Unlike, both plants behaved differently in terms of Cd absorption followed by AMF inoculation. 2) In both Room A and B Cd addition caused either higher or lesser Cd absorption as influenced by AMF. 3) Transfer coefficient of S. asper was lower after inoculation with AMF, while it was different in maize. In conclusion, AMF impacted Cd absorption by maize and S. asper through intercropping system as hyphae was assumed to be an important role in both plants in relation to Cd absorption.
