Mushrooms Grown with the Wave-Style Cultivation Method Yield High Output

The wave-style cultivation method involves spreading the compost on the bed surface into an undulating, wave-like shape when spreading compost and sowing spawn. Compared with a flat cultivation bed surface, this cultivation method can increase the fruiting area by more than 50%; it is superior to the flat cultivation method in terms of expelling harmful gases from the compost and regulating compost temperature; and without any additional investment, the yield per unit area can be increased by 30%-40%.

As for the implementation method, the production procedures, such as ingredient mixing in the early stage, fermentation, preparation and disinfection of the cultivation site, and the various management tasks in the later stage, are the same as those of conventional cultivation methods. The differences lie in the following: First, the box surface width is designed to be 1.2 m, which helps increase the utilization rate of ordinary agricultural film; second, layered sowing is adopted, that is, 2 layers of compost and 2 layers of spawn, which can speed up the spawn-running rate; third, when spreading compost and sowing spawn, 3 strips of compost, each 30 cm wide and 10 cm thick, are spread longitudinally on the box surface at equal intervals, leaving 2 gaps, each 15 cm wide, in the middle without compost for the time being. After the compost surface is slightly leveled, 1/3 of the spawn is sown on it. Then another layer of compost 15 cm thick is spread over the compost surface, and at the same time the reserved middle gaps are filled with compost 3 cm thick. The compost surface is then shaped into a turtle-back form so that peaks and troughs are formed, with the peaks 22 cm high and the bottom width of each wave row 15 cm. Finally, the remaining 2/3 of the spawn is evenly sown over the entire compost surface and gently patted flat with a wooden board. Then film and straw curtains are covered to keep warm and moist for spawn-running management. After 15-20 days, when the mycelium has grown into 1/2 or 2/3 of the compost, artificially improved casing soil is promptly covered. When casing, the casing soil thickness at both the peaks and troughs should reach 5 cm. After casing, 15-18 days later, large numbers of mushrooms can appear at the peaks and troughs.
