在温室中,研究了盆栽基质接种丛枝菌根(arbuscular mycorrhiza,AM)真菌摩西管柄囊霉Funneliformis mosseae对初生(种子播种育苗2个月后的幼苗)枳Poncirus trifoliata生长、菌根侵染、菌丝长度、土壤球囊霉素相关土壤蛋白(GRSP)含量和土壤结构的影响;同时研究了在AM真菌接种和柱花草间作条件下柱花草刈割对初生枳和柱花草生长、菌根侵染、土壤GRSP含量和土壤结构的影响.结果表明,与不接种相比,接种AM真菌显著地促进了初生枳生长,增加了土壤GRSP含量,并且土壤结构也得到改善.在AM真菌接种与柱花草间作的相同条件下,与柱花草未刈割相比,柱花草刈割对初生枳生长、菌根侵染、土壤GRSP含量和土壤结构均无显著性影响,但柱花草未刈割处理的菌丝长度是刈割处理的2.5倍.相关性分析表明,根际土壤大团聚体显著地与菌根侵染率、土壤GRSP含量和菌丝长度正相关,而生草刈割影响了丛枝菌根真菌菌丝长度,可能对土壤结构有不利影响.
Effects of AM fungi inoculation and grass mowing on growth and soil structure of potted young Poncirus trifoliata
Effects of arbuscular mycorrhiza(AM)fungus Funneliformis mosseae on the growth of young trifo-liate orange(Poncirus trifoliata L.Raf.),mycorrhizal infection,hyphal length,soil glomalin-related soil pro-tein(GRSP)content and soil structure were studied in greenhouse.The influence of the intercropped grass mowing and AM fungus on the growth of young trifoliate orange and stylo(Stylosanthes guianensias SW),mycorrhizal infection,GRSP and soil structure were also studied.Results showed that AM fungus inoculation significantly promoted the growth of trifoliate orange,increased GRSP concentration and improved soil struc-ture.There was no significant difference in the growth of trifoliate orange,mycorrhizal infection,GRSP con-centration and soil structure between stylo mowing and non-mowing treatments,but the hyphal length of AM fungi in stylo non-mowing treatment increased by 2.5 times compared to the mowing treatment.Correlation a-nalysis showed that macroaggregates in rhizosphere soil were significantly positively correlated with mycorrhi-zal infection rate,soil GRSP content and hyphal length,while stylo mowing affected the hyphal length of arbus-cular mycorrhizal fungi,which may adversely affect the soil structure.
