Abstract:: To study the responses of Stropharia rugosoannulata growth and quality to different additive formulation of cultural material,wild Stropharia rugosoannulata of Dangzhougou prairie, Gannan Plateau were separation and control to obtain cultivated species which were treated with unusual additive agents by single factor block method.Afterwards,measurement was made for morphological indicators like primordium appearance time,cap thickness,cap perimeter,stipe length,stipe perimeter,fresh weight per plant,dry weight per plant,plot yield,as well as quality indicators like crude fat,crude protein,ash,polysaccharides,crude fiber content to study the responses of Stropharia rugosoannulata growth and quality to different additive formulation of cultural material.The results showed that the best growth and quality of Stropharia rugosoannulata were observed in treatment 4(10 g gibberellin+10 g auxin+50 g plant ash),the content of polysaccharides,crude protein and crude fat were the highest,while the contents of ash and crude fiber were the lowest,and order of that of treatment 4>treatment 5>treatment 1>treatment 3>treatment 2>CK was shown.This provides a theoretical basis for selection of the best additive for Stropharia rugosoannulata planting,as well as the scientific basis for high yield,high quality production of Stropharia rugosoannulata.
