Abstract

Spent mushroom compost (SMC) substrates are commonly used as growth media for greenhouse crops and horticulture production. This study aimed to investigate the responses of physiochemical soil properties, enzyme activities, and microbial community compositions to different cultivation durations and SMC soil treatments on tomatoes. The experiment included the following treatments: SMC substrate and the surrounding soil after planting at 1, 3, and 7 years and comparing control treatments including non-planting SMC substrates and continuous mono-cropping soil. The results revealed that the SMC substrates had higher contents of total N P and organic C nutrients than the surrounding soil treatments. The physicochemical soil properties and soil enzyme activities of the SMC substrates were significantly decreased with longer cultivation duration. Microbial alpha diversity was higher in the SMC substrates regardless of cultivation duration than in the control treatments. It was observed that many beneficial microbes, such as bacteria of the Deinococcus-Thermus, Halanaerobiaeota, and Nitrospirae phyla, and the fungi of the Basidiomycota, Mortierellomycota, and Chytridiomycota phyla were enriched in the SMC substrates. The SMC substrate and surrounding soil had enriched several potentially beneficial microorganism genera such as the bacterial Saccharimonadales, Gaiella, Bacillus, and the fungal Thermomyces, Kernia, and Mortierella. Therefore, the agro-based SMC substrate grooved cultivation system is recommended as an environmentally compatible practice for tomato growth in the greenhouse.

农用废蘑菇堆肥基质改善温室番茄土壤性质和微生物多样性

废蘑菇堆肥(SMC)基质通常用作温室作物和园艺生产的生长介质。研究番茄不同栽培年限和SMC土壤处理对土壤理化性质、酶活性和微生物群落组成的影响。试验包括种植后1、3、7年SMC基质与周围土壤处理，以及不种植SMC基质与连作土壤对照处理。结果表明，SMC基质的全氮和有机碳含量高于周围土壤处理。SMC基质的土壤理化性质和土壤酶活性随着栽培时间的延长而显著降低。无论培养时间长短，SMC基质上的微生物α多样性均高于对照处理。结果表明，SMC基质中富集了许多有益微生物，如热球菌门、耐氧菌门和硝化菌门的细菌，以及担子菌门、Mortierellomycota和壶菌门的真菌。SMC基质和周围土壤丰富了几种潜在的有益微生物属，如细菌Saccharimonadales, Gaiella，芽孢杆菌，真菌thermoyces, Kernia和Mortierella。因此，推荐采用农基SMC基质沟槽栽培系统作为温室番茄生长的一种环境相容的做法。
