Edible Fungus Grid Cultivation Mode

The grid cultivation system uses a double-layer rigid grid as the load-bearing support structure for cultivation bags. Different frame structures of the grid rack are developed to suit various cultivation needs. One of the key advantages of this system is its design featuring square mesh holes. The cultivation bags (or sticks) are inserted into the grid, with the four corners forming heat dissipation channels. This innovative design effectively addresses the “burning fungi” issue that can arise in traditional stacked shelving systems during the cultivation process.

Grid-based cultivation racks are typically constructed from materials such as galvanized steel, plastic-coated steel, or wooden slats, with additional steel wire mesh welded to both sides for enhanced structural stability and durability. In just a few short years, the grid cultivation method has become the mainstream system for cultivating various edible mushrooms, including king oyster mushrooms, oyster mushrooms, and shiitake mushrooms.

Grid Cultivation for Pleurotus: A Case Study with King Oyster Mushrooms
In the development of Pleurotus species like king oyster mushrooms, a key requirement is the gentle airflow created by a light breeze. The success of their cultivation is largely attributed to the careful design of the cooling system in the fruiting chamber. Between the coil fans and the cultivation grid racks, a wide, horizontal insect-proof or shading net is installed to guide airflow.

When the coil fans operate, the airflow is directed forward, gradually reducing wind speed as the air travels further. Upon encountering resistance from the shelves, the air changes direction and flows downward, drawn by the negative pressure created by the fans. This creates a “return air” phenomenon, where the slow-moving air gently sweeps across the cultivation bags containing mushroom primordia. This airflow promotes transpiration and helps transport nutrients accumulated in the mycelium upward, supporting the development of the fruiting bodies.

The use of this air circulation system, in combination with the structure of the grid, ensures optimal growing conditions for the mushrooms, ultimately contributing to higher yield and quality. The gentle airflow prevents the overheating of the mycelium and maintains a stable environment for the mushrooms to thrive.
