- 摘要:
- 以畦床式栽培的大球盖菇为试材，采用出菇后期施用增菇肽（Z）、K1、黄腐酸、黄腐酸钾等营养物质的方法，研究了子实体营养成分、矿质元素和重金属含量变化，以期实现大球盖菇的增产、提质效果。结果表明：添加K1降低了子实体粗纤维含量，明显提高了灰分、脂肪、蛋白质和可溶性总糖含量；添加Z在不影响子实体粗纤维含量的前提下，明显降低了灰分含量，明显提高了脂肪、蛋白质和可溶性总糖含量；HY、Z、K1均可以提高大球盖菇子实体中Cu和Zn的含量，且K1的作用最为明显；Z对14种氨基酸和6种重金属均有明显的增加效果，但重金属含量均未超过GB 2762-2022的限量标准。因此，增菇肽对大球盖菇子实体营养品质具有较为明显的提升作用，可以作为大球盖菇出菇后期增产增效的营养补充物使用。
- Abstract:
- Taking Stropharia rugosoannulata cultivated in a bed style as the experimental materials,mineral elements and heavy metals in fruiting bodies were studied by applying mushroom enhancing peptide (Z)，K1，humic acid，and potassium humate to the culture medium in the late fruiting stage of Stropharia rugosoannulata culture process,in order to improve the yield and quality of Stropharia rugosoannulata，the nutritional components.The results showed that the addition of K1 reduced the crude fiber content of the fruiting body and significantly increased the ash content，fat content，protein content，and soluble total sugar content.Adding Z significantly reduced ash content and significantly increased fat，protein，and soluble total sugar content without affecting the crude fiber content of the fruiting body.Adding HY，Z，and K1 could all increase the content of Cu and Zn in the fruiting body of Stropharia rugosoannulata，and adding K1 had the most significant effect.Adding Z had a significant increasing effect on 14 amino acids and 6 heavy metals，but the heavy metal content did not exceed the limit standard of GB 2762-2022.Therefore，the mushroom enhancingpeptide (Z) had a significant effect on improving the nutritional quality of the fruiting body of Stropharia rugosoannulata，and could be used as a nutritional supplement for increasing yield and efficiency in the later stage cultivation of Stropharia rugosoannulata.
