Detailed Explanation of the Technique for Fruiting on Both the Front and Back Sides of Oyster Mushroom Beds
Using indoor frame-style cultivation of oyster mushrooms, fruiting simultaneously on both the front and back sides of the mushroom bed can, without increasing the substrate per unit area and without changing the substrate formula or the spawn sowing rate, produce an average of 16 kg of mushrooms per square meter of mushroom bed, and bring fruiting about 7 days earlier. 1. Setting up the mushroom bed frame structure: Build a frame indoors using materials such as moso bamboo, and fix the mushroom bed baseboard onto the frame. Generally the frame is 2 m high, with three tiers of mushroom beds, and the distance between tiers is 60-65 cm; beds managed from both sides are 110 cm wide, and beds managed from one side are 55 cm wide; the bed baseboard is made by nailing thin wooden boards, with 1.5-2 cm between each wooden strip. 2. Sowing: Select the Florida strain, which has a relatively broad suitable temperature range. Use the "layer sowing method": first lay a layer of plastic film on the mushroom bed baseboard, with a width 2.5 times the width of the bed baseboard, then spread a layer of substrate about 3 cm thick on the plastic film, then spread a layer of spawn, with the spawn layer no more than 1 cm thick; after spreading 4 layers of substrate and 3 layers of spawn in this way, press firmly, then cover the surface of the culture medium with a layer of water-soaked wet newspaper, and finally wrap the entire culture medium tightly with plastic film. 3. Fruiting management: About 60 days after inoculation, when the mycelium has basically finished colonizing the substrate, use a blade to make intermittent longitudinal cuts in the plastic film at the gaps on the back side of the mushroom bed baseboard. Each cut segment should be no longer than 15 cm, and both the horizontal and vertical spacing between cuts should be greater than 15 cm. Thereafter, each time the mushroom bed is watered, use a sprayer to spray an appropriate amount of water onto the cuts on the back side of the bed; other management is the same as conventional. After the first flush of mushrooms on the back side of the bed is harvested, the uncut plastic film on the back side of the bed can be slit open again with a knife. During the entire cultivation process, 2-3 flushes of oyster mushrooms can be harvested from the back side of the bed, with yield close to that of the front side of the bed.

Detailed Explanation of the Double-Sided Fruiting Method for Oyster Mushroom Beds
Using the double-sided fruiting method for oyster mushroom beds (Pleurotus ostreatus) makes effective use of the mushroom house space and increases the yield per unit area of the beds. The key technical points are as follows: 1. Bed equipment. Build a frame inside the mushroom house with moso bamboo or standing timber, generally 2 m high, with 3 tiers of beds, each tier spaced 60-65 cm apart, and the length depending on the actual conditions of the mushroom house. There are two widths: 55 cm for single-side management and 110 cm for double-side management. The bottom board of each bed tier is made by nailing thin wooden slats, with each slat spaced (gap) 1.5-2 cm apart. 2. Spreading substrate and inoculation

Fast-Track High-Yield Cultivation Techniques for Oyster Mushrooms in the Hot Season
High temperatures are extremely detrimental to the normal growth and high yield of oyster mushrooms. If conventional cultivation methods are still used, not only will the cost of oyster mushrooms be high, but the yield will also be low. However, if fast-track high-yield cultivation techniques are adopted, high yield and high efficiency can be achieved. Summarizing our years of experience, fast-track high-yield cultivation of oyster mushrooms in the hot season mainly involves the following key points: Selecting suitable spawn There are many varieties of oyster mushrooms. Pure high-temperature-type varieties have poorer quality, so it is advisable to choose wide-temperature-type varieties that are relatively tolerant of high temperatures, such as Suping, Aikang 558, Xide 33, Yaguang No. 1, as well as Gaoping No. 1, Sanxia 13

Semi-underground three-dimensional cultivation of oyster mushrooms yields high output and good returns
Semi-underground three-dimensional bed-frame cultivation of oyster mushrooms is a new approach explored in recent years to achieve high yields and improve economic returns. According to trials, on an area of 20 sq m, with 2000 kg of substrate, the annual output of oyster mushrooms is about 2500 kg, with a biological efficiency of over 120%. The key technical points are as follows: 1. Building the greenhouse: first dig a pit 1.8 m to 2 m deep and 4 m to 5 m wide, with the length determined as needed, and place the three-dimensional bed frames inside. On top, use bamboo poles and plastic film to build an arched shed, pack the surrounding edges firmly with soil, and cover with straw mats. Leave ventilation openings of about 30 square cm on all four sides, east, west, north and south, and build a small door on the west side for workers to enter and exit.

Four key measures for high-yield cultivation of oyster mushrooms
Supplementing nutrient solution: After harvesting the first flush of mushrooms, soak the mushroom bags in nutrient water with 0.1% urea and 3% white sugar for about 10 hours, allowing them to absorb a large amount of water, and the second flush will form quickly; then use a water injector to inject nutrient solution (vitamin B1, 20 mg, magnesium sulfate 20 g, boric acid 5 g, zinc sulfate 10 g, urea 25 g, cold boiled water 50 kg), reduce humidity and keep warm for 7 days, and the second flush will grow smoothly. Alternatively, break the mushroom skin at both ends of the bag once, place upside down on the ground, and irrigate with sufficient nutrient solution water (vitamin B

High-yield cultivation method of cutting oyster mushroom blocks into pieces, standing them upright and covering with soil
Mushroom farmers in Dongkan Town, Binhai County, Jiangsu Province, through years of oyster mushroom cultivation practice, worked out the six-character high-yield formula for oyster mushrooms of "cutting into blocks, standing upright, covering with soil", which increased the oyster mushroom yield per mu by more than 2000 jin compared with the past, with an increase rate of about 30%, and at the same time, production costs dropped greatly. Their high-yield experience mainly consists of three steps: "cutting into blocks, standing upright, covering with soil". The so-called "cutting into blocks" means that at the end of harvesting the second flush of mushrooms in furrow-bed cultivation, the dead mushrooms, stipes and the like remaining on the bed surface are cleaned up, and a sharp knife is used to cut the cultivation substrate into multiple pieces of about 50 cm

Management Methods and Technical Key Points for Oyster Mushrooms After Casing Soil
1. Heat preservation and moisture retention: After the oyster mushroom substrate logs are covered with soil, keep the shed temperature at 10°C-15°C, and keep the bed surface moist for about 15 days, until granular mushroom buds appear on the bed surface. After 3-4 days, when the caps grow to 1 cm in diameter, ventilate appropriately for 1 hour at noon. After the mushroom clusters grow larger, ventilate for 1 hour each morning and evening until harvest. Do not water during the growth period of the oyster mushroom fruiting bodies, so as not to drown the young mushrooms or splash soil onto the gills, which would affect the quality and edible value of the oyster mushrooms. 2. Harvesting: Harvest when the oyster mushroom caps curl inward slightly or are flat. When harvesting, support the lower left side of the mycelium with your left hand,

Detailed Explanation of Key Techniques for Simulated Wild Cultivation of Oyster Mushrooms
In recent years, diseases have occurred frequently during the cultivation of oyster mushrooms. This is mainly because the entire production process is under protected conditions from beginning to end, causing the vitality and disease resistance of the mycelium to continuously decline. Adopting simulated wild cultivation techniques can effectively solve this problem. 1. Substrate preparation and mycelium bag incubation are carried out according to conventional methods. 2. Standardized stacking to build mushroom walls. When primordia appear on individual mushroom bags, the mushroom walls can be built. The mushroom wall is generally 0.8 m wide and 15 m long; the gaps at the fruiting end of the mushroom columns are sealed tightly and evenly with mud, and all other gaps are filled solid with fertile soil, then watered to

What to Do When the Surface of Oyster Mushroom Substrate Turns Black? Cause Analysis and Control Methods
The main causes of blackening on the substrate surface and the control methods are: (1) Oyster mushroom mycelium soaked in water for a long time causes rot and blackening. In this case, the condensation water on the substrate surface should be absorbed and dried promptly. If it is grown on beds, excess water at the bottom should also be absorbed and dried promptly. (2) Contamination by foreign microorganisms and breeding of insect pests cause blackening. When blackening occurs, pests must be controlled or the affected part dug out promptly to prevent it from spreading.
