摘要: 在具有高密度VAM 真菌生长的枳( Poncirus trif oliata Raf. ) 苗的培养土中分别加入1%的4 种杂草的发酵物, 70 d 后测量结果表明: 枳菌根感染率普遍较高, 但与对照相比,杂草发酵物在显著促进枳苗生长的同时降低了枳菌根感染率, 其中发酵杂草处理对生长的促进作用更大, 降低菌根感染率更低; 高氮也降低菌根感染水平; 过高的菌根感染率导致寄生,抑制宿主的生长。

Abstract: 1% fermentation matters from four weeds ( Artemisia princeps Pampan, Cayracia jap onica Gagn, Ste llaria media Villars, Trifolium rep ens L. ) were respectively added into pot soils which contained high density propagules
of vesicular􀀁arbuscular mycorrhizal fungi for culturing trifoliate orange ( Poncirus trifoliata Raf. ) seedlings. After 70 days, mycorrhizal infection rates were high in all treatments. But compared with the control, fernentation matters signi􀀁ficantly stimulated the growth of trifoliate orange seedlings, reduced the mycorrhizal formation in roots of seedlings, and there were lower infection rates in treatments of fermented weeds than in that of fermented liquids; High concentration of nitrogen also could reduce the mycorrhizal formation level; The phenomena of parasitism and growth depression in mycorrhizal citrus took place when the mycorrhizal infection rate was too high.
