白浆土土壤养分及微生物群落结构对增施菌渣的响应
Response of Soil Nutrients and Microbial Communities to Increased Application of Mushroom Dreg in Albic Soil
摘要
Abstract
Albic soil is one of the typical low-yielding soil types in Heilongjiang Province,which poor nutrient and soil barrier issues limit the crop growth and sustainable development.Mushroom dreg,rich in nutrients and microbial activity,is considered as an effective soil amendment.However,the changes in soil biochemistry caused by mushroom compost application on albic soil were unclear.Therefore,this study conducted field experiments and combined high-throughput sequencing technology into three treatment groups:CK(unfertilized control),T2(standard fertilization supplemented with 3 t/hm2 of mushroom compost),and T1(standard fertilization control).The effects of mushroom compost on soil nutrients and microbial community characteristics and their interaction were analyzed.The study results found that adding mushroom dregs could improve the pH of albic soil and increase the overall nutrient content,enhance the richness and diversity of soil fungi,reduce the diversity and abundance of soil bacteria,increase the richness and diversity of soil fungi in some key phyla,such as Actinobacteria,Acidobacteria,Mucoromycota,Ascomycota and Chytridiomycota,with a trend of separation in the community structure of soil microorganisms.The main factors influencing the changes in soil bacterial and fungal communities were soil pH,total phosphorus,organic matter,and total potassium.This study not only contributed to an in-depth understanding of the mechanism of action of mushroom dreg in improving albic soil,but also provided technical support for the sustainable utilization of albic soil.关键词
