Tea tree mushroom cultivation techniques

1 Cultivation environment conditions

The growth temperature of the agaricus mushroom mycelium is 3-35 °C, and the optimum growth temperature is 23-28 °C. At temperatures above 30 °C, mycelial growth weakened or even stopped. The developmental temperature of fruit body differentiation is 23-26 °C, and the optimum temperature is 18-24 °C. Higher or lower temperatures will delay the primordial differentiation. According to the experiment, when the temperature is about 20 °C, the fruiting is the best. From budding to maturity, it takes about 10 days. The agrocybe aegerita is in the growth stage of mycelium, and the suitable moisture content of the culture material is 60%-65%. The air when the mycelium grows. Relative humidity is 65%-70%. Mycelium growth stage does not require light, excessively bright scattered light inhibit mycelial growth. Agrocybe aegypti is aerobic and is very sensitive to CO2. Poor ventilation, high CO2 content, slender stems, blocked cap development, easy to open umbrellas or teratogenicity. The mycelium can grow in the pH range of 4-7, grow best at pH 4.5-5.5, and the mycelium will grow poorly when the pH is lower than 4 or higher than 7.

2 Preparation before planting

Agrocybe aegerita has an indoor shelf erecting bag, mushrooming, bagging, soil and mushroom cultivation, and wall cultivation. Spring planting is generally carried out in late February to early March. Inoculation takes place in April and May, and it is cultivated in April and May. In autumn, it is planted at the end of August and early September, and in October-November, it is cultivated. Chai Mushroom bags are usually grown in the shed. Choose a simple mushroom house with high ground, sunny ventilation, convenient transportation, near water source, and no pollution around. The structure is best for brick and tile structure. A bed frame can be set in a mushroom house or a mushroom house. Fengxian's general culture formula is 40% of wood chips, 30% of cotton seed hull, 16% of wheat bran, 8% of corn flour, 4% of rapeseed cake powder, 1% of gypsum, 0.5% of sugar, 0.5% of potassium dihydrogen phosphate, and sulfuric acid. Magnesium 0.1%.

3 bag making

The ingredients were weighed in a conventional manner, the water content was adjusted to about 60%, the feed water ratio was about 1.0:1.2, and the pH before sterilization was about 7. After the water has penetrated evenly and in the fashion bag. Inflated bag cultivation usually uses 15.00 cm55.00 cm 0.04 cm low-pressure polyethylene film bag material, each bag of dry material 700 g. The specific operation of high temperature sterilization is: open valve heating, until the pressure rises to 0.8-1.1 kg/cm2, when the discharged gas reaches 107 °C, control for 2-3 h, ensure that the heat in the pot has enough time to penetrate the bag, and the temperature inside and outside the bag is uniform and then heated, so that the pressure rises to 1.5- 1.7 kg/cm2, maintaining 105-120 min. When the fire starts, the fire burns, and the center temperature of the bag is required to reach 97-100 °C within 2 hours after ignition, and then it is maintained for 15-18 hours [1-2]. , can not cool, keep the simmer, keep 100 °C. The cultivated original species and cultivars were thick and thick white, and were inoculated at both ends of the bacterial bag when the material was cooled to 28°C. It is also possible to perform punching and inoculation after sterilization. After inoculation, inoculate the wells with clear tape. Each bottle of bacteria can inoculate 25 bags.

4 Fungal management

The first 3 days after inoculation, the room temperature was adjusted to 25-27 °C to make the mycelium grow robustly. When the mycelium grows to 1/2 the depth of the material, its growth begins to slow down. At this time, loosen the bag mouth to loosen the cord, or puncture 1-2 lines of microporous oxygenation within 1.0-1.5 cm in front of the hypha growth. The relative humidity of the indoor air during the germination phase should be controlled at about 70%. There must not be excessive light, and doors and windows must be shaded.

5 Lei Lei Management

Outdoor mushroom shed method is as follows: the site is organized into a 30 cm wide, 15 cm high boring machine, the bed is covered with 1 layer of sand, and then two layers of film, the bag ends of the bag cut open stacked on the trampoline. The direction in which the bags should be stacked should be consistent with the direction of the doors and windows of the shed. Cut bag and row bag at the same time. Prior to the opening of the fungus bag, 34% carbolic acid solution or deltamethrin (killed) 3000 times solution and dimethoate 2000 times were used to disinfect the bag and disinfested the site. Use a sharp knife to cut the bag's membrane along the tie-knot [3]. After the bag is cut, a brown layer of bacilli will form on the surface around the bag opening as the browning time of the mycelium increases and the color deepens. The normal bacteriostasis was tan and rust brown, shiny, and normal fruiting. Combining with the turning of the bag, the temperature difference was continuously increased by 3-7 days, and the temperature difference between day and night reached 8-10 °C, until many white granules appeared and differentiated into mushroom buds.

6 Mushroom Management

During the mushrooming period, the temperature of the mushroom shed is maintained at 15-26 °C, preferably 20-24 °C. After the formation of the primordium, the number of water sprays should be increased to keep the relative humidity of the air between 85% and 90%. In the early stage, water is mainly sprayed into the space and the ground, and water can be directly sprayed into the fruit body in the middle and later stages. During the growth of the fruiting body, the respiration is strong. During the mushrooming period, the mushroom shed must be ventilated to keep the air fresh [4]. The light intensity should be maintained at 500-1 000 lx during the mushrooming period. Do not move the mushroom bag at will during growth. The light source of the mushroom shed was disturbed. Agrocybe can be used to collect 3-4 mushroom. After each harvest of a tidal mushroom, the bag is covered with a plastic (10915, 15.00, 0.14%) film, water is stopped for 7-10 d, and the relative humidity of the air is maintained at 70% to 75%. After the wound is collected at the mushroom, the wound is healed. Methods for budding.
