A mycelium growth bed for growing a solid substrate-bound mycelium through which the mycelium composite is easily and readily removed. This is achieved through the use of a perforation layer embedded between the mycelium substrate and the mycelium composite so as to create a uniform structural weakness and thereby enhancing harvesting abilities of the ex-substrate mycelium via a greatly reduced and uniform tear strength. The perforation layer, through which the mycelium grows, allows for the gated and controlled extrusion of a matrix of colonial cells that may be easily and uniformly delaminated from the underlying mycelium substrate.

A cultivation method for Morchella on patterned layer frames is provided. The method includes: (1) preparing and laying a culture substrate, and sowing; (2) supplementing an exogenous nutrient material; (3) mycelium culture; (4) primordium induction; (5) primordium differentiation; (6) management of a young mushroom period; (7) maturity management; and (8) erchao mushroom management. The method adopts a low temperature of (5-9 C.) to promote a transformation of an exogenous nutrition and adopts a low temperature of (2-4 C.) to induce a differentiation of primordium and other measures, to address a bottleneck of industrial development that cannot continuously supply fresh Morchella to the market, which is caused by some problems in the cultivation of Morchella, such as an unstable yield and seasonal limitation in the existing cultivation of Morchella. The method can carry out industrial facility cultivation for Morchella, and can obtain Morchella with stable yield and good quality.
