How to Eliminate Residual Pests in Pleurotus pulmonarius (Phoenix Mushroom) Greenhouses
The Phoenix mushroom (Pleurotus pulmonarius) is a relatively common edible fungus with a delicious flavor, deeply loved by consumers. Growing Phoenix mushrooms in greenhouses is a fairly common cultivation method, but poor management can still lead to pest infestations. So how do you eliminate residual pests in Phoenix mushroom greenhouses?
1. How to eliminate residual pests in Phoenix mushroom greenhouses?
Residual pests in Phoenix mushroom greenhouses can be reduced by covering the outside of the greenhouse with a shade net or black plastic film.
After harvesting Phoenix mushrooms, promptly remove the mushroom bags, mushroom roots and other residues as well as all kinds of other waste, which can reduce the breeding of pests and diseases. After clearing the debris, lime can be appropriately scattered to disinfect the mushroom shed, and no corner of the shed should be missed. After harvesting, promptly roll up the covering plastic film and shade net, and open the windows and doors to allow air circulation inside the shed; in winter, low temperatures can also be used to kill mushroom flies and residual pests and diseases.
2. Key Points of Phoenix Mushroom Cultivation Techniques
1. Selecting the spawn
Summer temperatures are relatively high, so when cultivating Phoenix mushrooms, choose varieties with strong adaptability, tolerance to high temperatures, high yield, good quality, a short growth cycle, strong resistance to pests and diseases, and tolerance to high temperatures.
2. Planting time
The Phoenix mushroom is a crop cultivated in the high-temperature season. Mushroom sticks can be made starting in April to May, and after inoculation the first harvest can begin by mid-June. Generally, another harvest can be taken about every half month, continuing until October, for a total of 5-6 harvests.
3. Cultivation techniques
(1) Preparing the substrate
Generally, cottonseed hulls, wheat bran, lime, gypsum powder, rice husks, cottonseed hulls, peptone, glutamic acid, etc. are mixed to make the substrate.
(2) Steaming and disinfecting the substrate
Generally, the substrate needs to be steamed for disinfection. Unlike ordinary steaming, the mushroom sticks are usually placed in plastic crates or packed in woven bags, or the mushroom sticks are directly stacked for steaming and disinfection. Plastic crates are best, as they are also convenient for transport. Do not steam too much at one time.
(3) Preparing the greenhouse
Phoenix mushrooms do not like direct strong light and prefer a darker environment, so shading measures should be taken when building the greenhouse, such as covering with black plastic film or a shade net. Anything that blocks light while allowing relatively good ventilation will do, as this provides a relatively dark, low-temperature environment for the growth of Phoenix mushrooms, which is more conducive to promoting their growth.
4. Inoculation and mycelium cultivation
Open the spawn bag, cut the mushroom sticks into evenly sized spawn blocks, put the divided spawn blocks into spawn bags or insert them into the substrate, then put the rings back on and plug them with sterilized cotton, and stack them for mycelium cultivation.
5. Fruiting management techniques
Temperature control. Phoenix mushrooms like high temperatures, but their temperature requirements differ at different growth stages, so it must be controlled flexibly.
Light control. During the mycelium growth stage, the light requirements are not high. However, during fruiting, light stimulation is needed for normal differentiation.
Humidity control. During mycelium growth, the humidity requirement is generally controlled at 70%, so that the substrate surface is slightly dry, which can inhibit the growth of contaminating bacteria; while the humidity requirement for the fruiting bodies is controlled at around 90%.
Ventilation management. Phoenix mushrooms have a high oxygen demand, so good ventilation better promotes mycelium growth and fruiting body growth. When the oxygen supply is insufficient, poor mycelium growth and deformed mushrooms will occur, so be sure to pay attention to ventilation when building the greenhouse.
