为了降低龙牙百合栽培过程中农药的使用量,提高龙牙百合的产量和品质,设置空白地、地膜覆盖+一次性施肥种植模式(PM+OTF)与传统露地栽培模式(OFC)3 个处理,对不同处理土壤中的细菌、真菌多样性进行比较,分析种植模式的改变对龙牙百合地下部生长微生物环境的影响.结果表明,PM+OTF模式的土壤真菌群落丰富度较OFC模式低,但群落多样性不存在显著差异;2 种栽培模式土壤的细菌丰富度及多样性不存在显著差异.PCA主成分分析表明,PM+OTF模式的土壤微生物群落结构组成更接近空白地.土壤真菌与细菌群落组成分析显示,2 种栽培模式在门水平上的微生物多样性不存在显著性差异;但细菌的被孢霉属(Aquisphaera)、...

In order to reduce the use of pesticides in the cultivation process of Lilium brownii var.Viridulum and improve its yield and quality,a blank field,plastic film coverage,and one-time fertilization planting(PM+OTF)model treatment and traditional open field cultivation(OFC)model treatment were set up to compare the diversity of microbiota and fungi in the soil of different treatments,and analyze the impact of planting mode changes on the underground growth microbial environ-ment of Lilium brownii var.viridulum.The results showed that the richness of soil fungal communities in the PM+OTF mo-del w...
