Abstract:

In order to find out the key factors of imitative wild cultivation of Dictyophora indusiata under moso bamboo stands, and to provide theoretical basis for interplanting Dictyophora indusiata in bamboo stands. L₉(3⁴) orthogonal test were adopted to study the factors affecting the yield of Dictyophora indusiata. The four factors:planting time, strain, planting mode, cultivation matrix thickness, and each factor was set at three levels. The results showed that the four factors had significant effects on the yield and biological efficiency of Dictyophora indusiata, but had no significant effect on the mushroom growth period (P>0.05). The planting time had significant effects on the mushroom growth period (P<0.05). The best cultivation mode for planting Dictyophora indusiata in the moso bamboo stands in Zhejiang Province is to dig a circular planting ditch around the bamboo stump or open a horizontal ditch along the contour line at the end of March, with a width of 30 cm and a depth of 10 cm, lay substrate of bamboo sawdust with a thickness of 20 cm and use the selected strain D₈₉ by research group for cultivation.
