Taking‘Zhijin Dictyophora 2＃’as the experimental material,the effects of different treatments on the growth of mycelium and fruiting body of ‘Zhijin Dictyophora 2＃’ were studied by imitating wild cultivation of Dictyophora rubrovalvata in forest land with different formula of Pennisetum giganteum instead of rod,so as to provide reference for the development and utilization of Pennisetum giganteum and ecological cultivation of Dictyophora rubra in Guizhou Province.The results showed that the mycelia of ‘Zhijin Dictyophora 2＃’ grew slightly faster in the medium with Pennisetum giganteum,but the mycelia was thin and poor.Compared with CK treated with birch sawdust,the number of first egg was less,but the weight difference of single egg was not significant.The appearance of ‘Zhijin Dictyophora 2＃’in the CK was better than that of the Pennisetum giganteum treatment 1,treatment 2 and treatment 3,and the economic yield of CK (2 184.34 g?m-2) was significantly higher than treatment 1 (2 056.66 g?m-2),treatment 2 (2 031.26 g?m-2) and treatment 3 (1 955.94 g?m-2).‘Zhijin Dictyophora 2＃’ showed a strong preference for birch sawdust.Analysis of amino acid content of ‘Zhijin Dictyophora 2＃’ planted in substitute of Pennisetum giganteum showed that,the total amino acid content of the seed of ‘Zhijin Dictyophora 2＃’ was 9 070 mg?(100g)-1,in which the essential amino acid content of human body accounted for 37.8% of the total amino acid content,and the pharmacodynamic amino acid content accounted for 77.6% of the total amino acid content.
