山东农业大学园艺科学与工程学院等单位研究人员在盆栽条件下,研究了啤酒糟和白酒糟对连作平邑甜茶幼苗生长及其连作土壤中微生物的影响。结果表明,连作土壤添加酒糟可显著提高平邑甜茶幼苗株高、干样质量、鲜样质量等生物量指标。添加酒糟后土壤中细菌、真菌数量与连作土对照相比也有明显提升。通过聚类分析、主要成分分析和多样性分析发现,加入酒糟后 Shandong Agricultural University College of Horticulture Science and Engineering and other units of researchers under potting conditions, brewer’s grains and white grains of continuous cropping of Malus hupehensis seedlings and its continuous cropping of microorganisms. The results showed that the addition of distiller ’s grains in continuous cropping soil could significantly improve biomass, such as plant height, dry sample quality and fresh sample quality. The amount of bacteria and fungi in the soil after adding the stillage was also significantly increased compared with that of the control. By cluster analysis, the main component analysis and diversity analysis found that after the addition of distiller’s grains
