摘要:
丛枝菌根(Arbuscular mycorrhiza, AM)真菌在退化农林生态系统的生物修复研究是当今生态及环境科学领域的热点问题。许多研究表明AM真菌促进植物对土壤磷的吸收利用,然而不同的AM真菌对土壤磷形态及其转化规律的影响未见报道。为此本试验通过盆栽试验以不接种处理为对照,分别接种幼套近明球囊霉(Claroideoglomus etunicatum, Ce)、摩西管柄囊霉(Funneliformis mosseae, Mo)、根内根孢囊霉(Rhizophagus intraradices, Ri)3种AM真菌,通过连续种植两茬玉米后(2015-2016年)测定AM真菌侵染率、玉米磷素吸收和土壤磷素形态的变化。结果表明:(1)接种3种AM真菌均成功侵染玉米根系,两茬玉米根系AM真菌侵染率顺序均为Ce ≥ Mo ≥ Ri,虽然第二茬侵染率(38.3%-68.8%)较第一茬(14.5%-32.5%)有所提高;(2)随着AM真菌的侵染,接种处理显着提高了玉米磷素吸收,提高幅度达25.5%-82.0%;(3)接种3种AM真菌均显着提高了土壤活性态无机磷(H2O-Pi、NaHCO3-Pi)和中等活性无机磷(NaOH-Pi)含量;而对土壤中度稳定态磷(HCl-P)和稳定态磷(Residue-P)含量不受影响;接种Mo和Ce对土壤NaHCO3-Pi含量提高最显着,分别提高了141.02%和88.47%,其次为Ri (43.12%); (4)接种Mo和Ri显着提高了土壤中等活性态无机磷(NaOH-Pi)的含量,分别比CK提高了36.15%和18.82%。总之,接种不同AM真菌均能提高根系侵染率、磷素吸收以及促进土壤磷素活性态、中等活性态无机磷(H2O-Pi、NaHCO3-Pi、NaOH-Pi)的转化,提高了土壤磷素的生物有效性,其中接种Ce和Mo能够更好的促进土壤中的磷素向植物可供利用的形态转化,提高植株吸磷量,是适合该矿区土壤的经济高效菌种。(表2 参33)
Abstract:
It is a hot issue in the field of ecology and environmental science that arbuscular m ycorrhizal (AM) fungi is used in bioremediation research in fragile mining area. Many researches have shown that AM fungi promote plants to absorb soil P, while the effect with different AM fungi on soil P forms and its transformation and soil P availability was barely reported. Therefore a pot experiment was conducted with inoculation with three AM fungi, including Claroideoglomus etunicatum (Ce ) , Glomus Mosseae (Mo) and Rhizophagus intraradices (Ri), respectively, with no inoculation AM fungi as the control (CK). Across consecutive two years corn planting (2015-2016), the AM fungal colonization rate, corn P uptake and changes of soil P forms were analyzed. The results showed that: (1) inoculation with three AM fungi was successfully formed a symbiotic relationship with corn roots with the colonization rate in the order of Ce ≥ Mo ≥ Ri during the consecutive two years planting, although the colonization rate with the second planting (38.3%-68.8%) was higher than that (14.5%-32.5%) with the first season,(2) the inoculation treatment with AM fungi significantly increased maize P uptake by 25.5%-82.0%, (3) the inoculation treatment with three AM fungi significantly increased the content of soil active inorganic P (H2O-Pi, NaHCO3-Pi) and medium active inorganic P (NaOH-Pi),while no significant effect on moderately stable P (HCl-P) and stable P (residue-P); inoculation treatments with Mo and Ce had the highest values on soil NaHCO3-Pi, which increased by 141.02% and 88.47% respectively, followed by Ri (with the increase of 43.12%); (4) and inoculation with Mo and Ri increased soil medium active inorganic P(NaOH-Pi) by 36.15% and 18.82% relative to the value of CK. In a word, inoculation with AM fungi increased root colonization rate, maize P uptake and soil P transformation into active and medium active inorganic P (H2O-Pi、NaHCO3-Pi、NaOH-Pi)thus soil P availability was increased. Of the treatments, inoculation with Ce and Mo were the economic and effective genus since they improved corn P uptake and soil P transformation into bio-availability in this coal-mining subsidence reclamation area.
