摘要
通过温室盆栽试验,研究了在退化草地土壤中添加废蘑菇基质(SMS, 0%、10%、20%和30%,w/w)对紫花苜蓿生长和养分吸收的影响。同时,通过与无机肥(CF、200 N mg/kg和30 P mg/kg)施用处理的比较,探索SMS对紫花苜蓿产量的最适宜添加量。结果表明,与对照(CK)相比,10%、20%、30%和CF处理的苜蓿地上部生物量分别增加了1.19倍、1.67倍、1.77倍和1.77倍。20%SMS处理的叶片总碳和茎部总氮含量显著高于其他处理。添加SMS使结节数量增加,其中20%的SMS处理效果更好。随着SMS添加量的增加,土壤溶解有机碳、速效磷、微生物生物量碳氮浓度显著升高,除速效磷外,CF处理与CK处理间差异不显著。地上部生物量与速效磷呈极显著相关。综上所述,在退化草地土壤中添加20%和30%的SMS可以显著改善土壤养分和微环境,提高苜蓿产量,但考虑到经济效益,20%的SMS是最合适的施用量。本研究为SMS在野外的大规模应用提供了理论依据和技术支持。引用
The addition of spent oyster mushroom substrates has positive effects on alfalfa growth and soil available nutrients
This study aimed to investigate the effects of spent mushroom substrate (SMS, 0%, 10%, 20%, and 30%, w/w) addition to degraded grassland soil on the growth and nutrient uptake of alfalfa through a greenhouse pot experiment. Meanwhile, we compared with the inorganic fertilizer (CF, 200 N mg/kg and 30 P mg/kg) application treatment, and explored the most suitable SMS addition amount for alfalfa yield. Our results showed that compared with the control treatment (CK), 10%SMS, 20%SMS, 30%SMS, and CF treatments increased alfalfa shoot biomass by 1.19, 1.67, 1.77, and 1.77 times, respectively. Total carbon in leaves and total nitrogen contents in stems of 20%SMS treatment were significantly higher than other treatments. Adding SMS increased the nodule number, especially the 20%SMS treatment. In addition, the concentrations of dissolved organic carbon, available phosphorus, and microbial biomass carbon and nitrogen were significantly enhanced with increasing SMS addition, and there was no significant difference between CF and CK treatments except for available phosphorus. Shoot biomass was significantly correlated with available phosphorus. In summary, adding SMS (20% and 30%) to degraded grassland soil can significantly improve soil nutrients and microenvironment to increase alfalfa yield, but considering economic benefits, 20%SMS is the most suitable application amount. This study provides the theoretical basis and technical support for the large-scale application of SMS in the field. Citation
