摘要:

为丰富桑枝屑栽培灵芝相关技术参数,明确桑枝屑的最适颗粒度,以20、18、14、12、8 mm 5个不同粒径桑枝屑配方(45%桑枝屑、45%玉米芯、5%麸皮、4%玉米粉、1%石膏)代料栽培‘川圆芝1号',比较不同处理灵芝菌丝生长速度、子实体性状、产量和活性成分。结果表明,中等颗粒度(8~14 mm)桑枝屑栽培灵芝可促进菌丝较快生长(6.27 mm/d);而桑枝颗粒度为18 mm时,灵芝单朵鲜重及产量最大,分别达95.59、34.10 g/袋,且子实体三萜酸和多糖含量较高(1.33、1.20 g/100 g)。综上,以18 mm颗粒度的桑枝屑栽培灵芝更加优质高产。

Abstract:

To enrich the technical parameters of Ganoderma lucidum cultivation with mulberry chips and determine the optimum particle size of mulberry chips, the G. lucidum cultivar ‘Chuanyuanzhi No.1' was cultivated with different-particle-size mulberry chips (20, 18, 14, 12 and 8 mm) in bags and the mycelial growth rate, morphological characters and active components of the fruiting bodies and yield of different treatments were compared in this study. The substrates consisted of 45% mulberry chips, 45% corncob, 5% bran, 4% corn flour and 1% gypsum. Results showed that the mycelia grew fastest in the substrates with medium-particle-size mulberry chips (8-14 mm) with the growth rate of 6.27 mm/d. However, G. lucidum cultivated with 18 mm-particle-size mulberry chips (D18) had the biggest fresh single weight (95.59 g) and yield (34.10 g/bag). In addition, treatment D18 had higher content of triterpenoid acid and polysaccharide in the fruiting bodies, reaching 1.33 and 1.20 g/100 g, respectively. Conclusively, G. lucidum cultivated with 18 mm-particle-size mulberry chips had higher yield and better quality.
