Mushroom and wood ear mushroom greenhouse
For the construction of mushroom film greenhouse and wood ear mushroom greenhouses, single-arch greenhouses and multi-span film greenhouses are generally used, while glass greenhouses are rarely adopted due to tunnel greenhouse high investment and operational costs. For the production tunnel greenhouse of mushrooms and wood ear mushrooms, single-arch tunnel greenhouse and multi-span film greenhouses can meet the usage requirements. The construction guidelines mainly cover the following aspects.
I. Site Selection and Planning
Choose a location that is flat, spacious, well-ventilated, has abundant water sources, and is accessible by transportation. Plan the orientation of the mushroom greenhouse based on film greenhouse the cultivation scale and site conditions. Generally, a north-south orientation is preferable as it promotes uniform light exposure. At the same time, properly arrange the passageways, film greenhouse working areas, and areas for placing the mushroom substrates to ensure efficient and convenient operations.mushroom greenhouse
II. Design of Greenhouse Structure
1. Frame material: Galvanized steel pipes can be selected. They have strong anti-corrosion properties and are durable. The appropriate pipe diameter and wall thickness should be determined based on the span and height of the greenhouse. For a greenhouse with a span of 8 - 10 meters, the main arch frame can use pipes with a diameter of 32 millimeters and a wall thickness of 1.5 - 2 millimeters, ensuring they can withstand loads such as wind and snow. Alternatively, galvanized elliptical pipes can also be used, but the construction cost is higher, but they perform better in resisting wind and snow.
2. Roof and Plastic Film: The roof is designed in an arc shape, which is conducive to drainage and light penetration. The plastic film is made of polyethylene tunnel greenhouse or polyvinyl chloride with good light transmittance, excellent heat preservation properties, and good resistance to aging. The thickness is 0.1 - 0.12 millimeters. It is also equipped with fixing accessories such as pressure lines and slots to prevent the film from being blown off by strong winds film greenhouse.
3. Ventilation and Cooling System: Ventilation openings are set on both sides of the tunnel greenhouse. The ventilation area can be controlled using a roll-up film device to ensure proper air circulation and regulate temperature and humidity. In cases where higher requirements are needed, a fan and water curtain cooling system can also be configured.
III. Internal Facilities Configuration
Sun shading and heat preservation system: Install sunshade nets to block strong sunlight and lower the temperature inside the mushroom greenhouse during hot summer days; in winter, add insulation covers or straw curtains, covering the mushroom greenhouse at night to enhance the insulation effect, and retract them during the day to ensure adequate light.
2. Micro-sprinkler system: Install pipelines and micro-sprinkler heads to evenly spray water mist, meeting the water requirements tunnel greenhouse of black fungus at different growth stages. At the same time, it can be combined with the fertilization system to film greenhouse achieve integrated water and fertilizer management, thereby improving water resource utilization and production efficiency.
3. Bacterial Rod Storage Rack: Construct a multi-level storage rack. The material can be stainless steel or steel treated for rust prevention. The spacing between tunnel greenhouse layers is 30 - 40 centimeters. Film greenhouse design facilitates the mushroom greenhouse placement film greenhouse and management of bacterial rods, effectively utilizes space, increases the number of cultivation, and mushroom greenhouseenhances the yield per unit area.
When building a tunnel greenhouse for edible fungus such as maitake, various factors need to be comprehensively considered to ensure that the mushroom greenhouse facilities are complete and the functions are all in place, so as to create a favorable environment for the growth of maitake and achieve the goal of high-quality and high-yield production.
