Environmental conditions required for the growth of volvariella volvacea
1. Temperature: volvariella volvacea is a high-temperature type of umbrella bacteria. The temperature required for spore germination is 25-45 ℃, and the suitable temperature is 40 ℃. It can not germinate above 45 ℃ or below 25 ℃. The suitable temperature range for the mycelium growth of volvariella volvacea is 20-40 ℃, and the most suitable temperature for mycelium growth is 35-36 ℃. At this temperature, the mycelium grows fastest. Under the condition of less than 15 ℃ or more than 42 ℃, the mycelium grew slowly, stopped growing at 10 ℃, and died quickly below 5 ℃. The optimum temperature for fruiting body development is 2832 ℃.

Aerated composting technology of volvariella volvacea culture material
Straw mushroom can be planted with rice straw plus some auxiliary materials or a single cottonseed shell. Before building the pile, expose the rice straw or cottonseed shell for 1 day, then soak it in pH11~12 lime water and fish it out.

Types and preparation of Culture Materials for volvariella volvacea
The raw materials needed for volvariella volvacea cultivation come from a wide range of sources. At present, the most commonly used are rice straw, wheat straw, waste cotton and cottonseed hulls. The waste of some edible fungi can also be used to cultivate straw mushrooms. 1. Choose golden, mildew-free dried straw and use it in the sun for 1 or 2 days to prevent the emergence of umbrellas or other miscellaneous bacteria during cultivation. There are generally two ways to treat rice straw. one is to cut the straw into about 5 cm long, then soak it in 3% lime water for 1 to 2 days, and then add 20% 25% dried pig manure or dried cow dung to make it.

Processing of candied straw mushroom and mushroom
First of all, it is necessary to understand the tissue structure and chemical composition of edible fungi such as grass shavings and mushrooms. This kind of edible fungus has large water content, loose and fragile tissue, and it is easy to brown the surface in the processing process to affect the color of the finished product. Therefore, the processing technology should consider the above characteristics, the processing technology is as follows: 1, raw material selection: pick out rotten, sick and chromatic aberration, aged straw mushrooms and mushrooms, as far as possible fresh materials. 2. Pretreatment: after the raw materials have been selected and arranged, the color protection measures should be taken promptly and soaked in 1% salt water, or with

Production Technology of preserved Straw Mushroom
1. Material selection and treatment. Select straw mushroom with full body, no umbrella and no mechanical damage, immediately after harvest, put it into 0.03% sodium pyrosulfite solution to deal with 6Murray for 8 hours (hours), then rinse with clean water. 2. Blanching and hardening. Blanch the treated volvariella volvacea in boiling water for 2--3min (minutes) to kill the enzyme activity, remove immediately after blanching, cool in cold water, remove after cooling, and soak in 0.5% murmur1% calcium chloride solution for 10 hours (hours).

Key points of cultivation techniques of straw mushroom and wheat straw
Volvariella volvacea is a kind of high-quality edible fungus and a typical high-temperature mushroom species, which is suitable for cultivation in summer. The optimum temperature for mycelium growth of volvariella volvacea was 3039 ℃, the optimum temperature was 36 ℃, the growth was very weak below 15 ℃ or above 42 ℃, the mycelium stopped growing at 10 ℃, and the mycelium died below 5 ℃. The optimum temperature of fruiting body is 28-33 ℃, but it is difficult to form fruiting body below 24 ℃. Therefore, the temperature management of cultivated volvariella volvacea is very strict. 1. Site selection and treatment. Select leeward, sunny, highly dry loam, rich in organic matter to do east-west sunny border, wide 80cm

Two-stage cultivation techniques of volvariella volvacea
Straw mushroom, also known as orchid mushroom, bract mushroom. Nutritious, delicious and delicious, in the hot summer, using several straw mushrooms to make soup for consumption, unique flavor, endless aftertaste, deeply welcomed by consumers. The growing season of volvariella volvacea is from June to September, which is a variety with fast growth, short production period and quick effect, from sowing to mushroom production for 8-10 days. By using the new two-stage cultivation technique, 50 kg of fresh mushrooms can be produced per 100 kg of raw materials in 40 days, with an output value of 300-400 yuan. The two-stage cultivation technique of volvariella volvacea is the author's production practice for many years.

Production quality requirements of volvariella volvacea
Volvariella volvacea strains, whether isolated or introduced, must go through the mushroom production test, and can be expanded and cultured only after it is confirmed to be high-yield and high-quality mushroom species, so as to avoid economic losses. Qualified strain quality requirements (for reference): ① hyphae are yellowish and transparent, with or without chlamydospores (vary from variety to variety), the mycelium is evenly distributed in the whole bottle, and the water content of the medium is suitable (about 65%). ② strain is suitable for age, fresh, robust and strong in growth. ③ is free of miscellaneous bacteria and insect pests. Where there are the following feelings

Distinguishing the advantages and disadvantages of volvariella volvacea
The quality of volvariella volvacea should be identified before cultivation, and high quality strains should be selected as far as possible. The appearance of high-quality bacteria is as follows: the hyphae are stout, the upper and lower hyphae develop uniformly, and the aerial hyphae are white or translucent. The specific identification methods are as follows: first, the bacteria used for cultivation are about 30 days old, the hyphae are thick and white, there are light brown chlamydospores on the hyphae, and the fragrance of straw mushroom can be smelled after pulling out the cotton plug. This kind of strain is a high-quality strain, which eats food quickly and grows vigorously after sowing. If there are few chlamydospores, the hyphae are still young and can continue to grow.

Causes and control of mycelial atrophy of volvariella volvacea
1. The use of inferior bacteria: the age is too long or too short, the strain degenerates, the mycelium is weak, the stress resistance is poor, or the strain is stored in an environment where the temperature is too low or too high for a long time, there will be the phenomenon of non-germination and mycelium shrinkage after sowing. Prevention and treatment: select the right age, high-quality bacteria, and ensure that the temperature in the culture process is not too low. two。 Improper control of culture material temperature: when the air temperature is high, the culture material is thick, and the heat preservation performance of the mushroom room is good, the temperature in the culture material exceeds 42 ℃ for a long time after sowing, which will lead to mycelium shrinkage, death and burning bacteria.
