摘    要:【目的】明确酸性土壤中丛枝菌根真菌(arbuscular mycorrhizae fungi,AMF)菌剂多样性在玉米籽粒产量和磷、钾养分吸收方面的作用,能够为农田微生物肥料配施、养分利用率提高等方面提供理论依据。【方法】2019和2020年玉米生育期,选用4种不同种丛枝菌根真菌类型(摩西斗管囊霉Funneliformis mosseae,A;扭形球囊霉Glomus tortuosum,B;地表球囊霉Glomus versiforme,C;地斗管囊霉Funneliformis geosporum,D),设置不接菌处理(CK),接种单一AMF菌剂、2种AMF混合菌剂、3种AMF混合菌剂和4种AMF混合菌剂共16个处理,研究玉米籽粒产量、植株各器官生物量及其磷、钾累积量对不同菌剂类型以及菌剂多样性的响应。【结果】与对照相比,两个试验年度所有接菌处理均能增加玉米籽粒产量及其磷、钾累积量,其中接种A、B、C、D 4种单一菌剂处理的玉米籽粒产量均值分别增加57.9%,26.9%,40.5%和32.9%;磷累积量增加77.8%,48.2%,26.2%和75.8%;钾累积量增加85.5%,62.1%,59.0%和63.5%。随AMF菌剂多样性增加,两个试验年度玉米籽粒产量呈增加趋势,表现为4种混合菌剂>3种混合菌剂>2种混合菌剂>单一菌剂,其中4种混合菌剂处理籽粒产量比单一菌剂处理均值高12.3%;籽粒磷累积量表现为2种混合菌剂>4种混合菌剂>3种混合菌剂>单一菌剂,其中2种混合菌剂处理籽粒磷累积量比单一菌剂高23.2%;但AMF菌剂多样性处理之间玉米籽粒钾累积量差异不显著。【结论】在酸性土壤条件下玉米接种不同类型丛枝菌根真菌均能显著增加籽粒产量及其磷、钾累积量,其中Funneliformis mosseae改善玉米籽粒产量及其磷钾累积量的作用最佳。丛枝菌根真菌菌剂多样性增加能显著提高玉米籽粒产量和磷累积量,其中4种混合菌剂处理的增产效果较好,而2种混合菌剂处理的养分吸收积累量较高。生产上应根据高产优质不同目的,选择接种合适的丛枝菌根真菌类型并进行菌剂之间合理的搭配。

Abstract:【Objective】The aim of this study was to clarify the effects of different arbuscular mycorrhizae fungi (AMF) inoculants and their diversity on maize grains yield and the absorption and accumulation of phosphorus (P) and potassium (K) in acidic soil, so as to provide a theoretical basis for the application of farmland microbial fertilizer and the improvement of crop nutrient uptake. 【Method】Four different AMF species (Funneliformis mosseae, A; Glomus tortuosum, B; Glomus versiforme, C; Funneliformis geosporum, D) were selected as experimental materials in 2019 and 2020, and a pot experiment with sixteen treatments was established during maize growth periods, including CK (non-inoculating AMF species), inoculating single AMF treatment, two AMF mixed treatments, three AMF mixed treatments, and four AMF mixed treatments. The maize grain yield, plant biomass and their P and K accumulation were analyzed. 【Result】Compared with CK, the presence of each type of AMF species could increase maize grain yield and their P and K accumulation. Compared with CK, the presence of A, B, C and D increased maize grain yield by 57.9%, 26.9%, 40.5% and 32.9%, respectively, increased the maize grain P accumulation by 77.8%, 48.2%, 26.2% and 75.8%, respectively and increased maize grain K accumulation by 85.5%, 62.1%, 59.0% and 63.5%, respectively. With AMF inoculant diversities increasing, the average values of maize grain yield showed an increasing tendency, with four AMF mixed treatments>three AMF mixed treatments>two AMF mixed treatments>single AMF treatments, and the average grain yield of four AMF mixed treatments was 12.3% higher than that of the single AMF treatments. The tendency of grain P accumulation among the AMF diversity treatments was two AMF mixed treatments>four AMF mixed treatments>three AMF mixed treatments>single AMF treatments, and the average grain P accumulation for two AMF mixed treatments was 23.2% higher than that of single AMF treatments. However, there was no significant difference of grain K accumulation among AMF diversity treatments. 【Conclusion】In acidic soil, the inoculation of different AMF species could significantly increase maize grain yield and their P and K accumulation, and the effects of Funneliformis mosseae was best on improving maize grain yield and their P and K accumulation among four AMF species. The increase of AMF inoculant diversities could significantly improve maize grain yield and their P accumulation, while the four mixed AMF showed a better effect on grain yield, and on grain nutrient uptake for two mixed AMF. All of these indicated that, according to the purposes of high grain yield or high grain quality in production, the suitable types of AMF species should be selected to inoculate their host, and the mix of different types of AMF species should matched reasonably.
Keywords:arbuscular mycorrhizal fungi  inoculant diversity  maize yield  phosphorus accumulation  potassium accumulation
