High Yield and High Efficiency Cultivation Technique of Volvariella volvacea

The mature season of straw mushroom is in summer every year, so it can be seen at any time in summer. Straw mushroom is very popular in life, so many people want to grow it now. But before cultivation, we should not be blind, we must first have an in-depth understanding of it.

High yield and High efficiency cultivation techniques of volvariella volvacea

1. The establishment of bed frame: the bed frame of straw mushroom cultivation is the same as that of mushroom cultivation. The bedstead and the mushroom room should be arranged vertically, that is, the mushroom room in the east-west direction, the north-south arrangement of the bedstead, do not lean against the wall around the mushroom bed, the walkway against the wall, the aisle between the bedstead and the bedstead is 67 centimeters wide, the distance between the bedstead is 67 centimeters, and the bottom floor is more than 17 centimeters from the ground. The number of bed frames depends on the height of the mushroom room, generally 4mur6 layers, bed frame width 1. 3-1. Five meters. The bed frame can be made of bamboo and wood, and the reinforced concrete bed frame is better. There is a pair of upper and lower windows on the walls at both ends of each aisle. The size of the window is 40 cm wide and 50 cm high, and a wind tube is installed on the roof in the middle of the aisle between the bedstead, 1 high. 5 meters, about 40 centimeters in diameter.

2. Secondary fermentation of culture material: shake the culture material after composting fermentation, mix it well, and move it into the bed frame of the mushroom room while it is hot. At this time, the best water content of the culture material is about 70%, and the pH value is about 9. The thickness of the culture material of different cultivation materials is also different, the thickness of the waste cotton residue or cottonseed shell culture material is 7ml 10cm, the chopped rice straw culture material is 12cm 15cm, and the long rice straw paving material is 20cm. When the temperature is high in summer, the culture material should be thinner. The culture material should be thicker when the temperature is low in winter. After laying the material, immediately put steam or coal stove into the mushroom room to heat up, so that the culture temperature reached about 65 ℃, maintain 4 Mel for 8 hours, and then cool down naturally. When the door and window are opened at about 45 ℃, the secondary fermentation can kill the pests and harmful bacteria in the mushroom room and culture material, which is beneficial to the mass reproduction of beneficial microorganisms such as high temperature actinomycetes, is more beneficial to the growth of volvariella volvacea, and is easy to obtain high yield.

Growth conditions of volvariella volvacea

1. Nutrition. Mushroom has normal growth and development under the condition of high temperature, strong metabolism, fast growth rate and high yield. in addition to sufficient carbon source, mushroom needs more available nitrogen nutrition than Pleurotus ostreatus.

2. Temperature. The temperature range of mycelium growth was 20: 38 ℃, and the optimum temperature was 26: 32 ℃. The temperature range for the growth and development of fruiting body is 2438 C, and the optimum temperature is about 26 31 ℃. The temperature of mycelium growth and fruiting body growth and development is almost the same, and the mycelium is transformed from vegetative growth to fruiting body breeding stage, which does not need the temperature difference stimulation of cooling, which is different from the characteristics of Agaricus bisporus.

3. Moisture. Because of the high growth temperature, fast growth rate and more mushroom production, the water demand is more than that of ordinary varieties. The water content of compost is about 65% during the sterilization period. The water content of the overlying soil layer (vegetable garden sandy loam) during mushroom emergence is about 22%. The relative humidity of the air during the fruiting body growth is about 90%.

Management of emergence period of volvariella volvacea

Generally, 6 days after sowing, when the straw mushroom hyphae begins to kink, the humidity of the material surface should be increased in time, and the "mushroom water" should be used to increase indoor light to promote the formation of straw mushroom fruiting body. When a large number of buds of small white spots are formed, it is mainly moisturizing, the air relative humidity is maintained above 90%, and water spraying is suspended on the bed surface. When the fruiting body has buttons, the amount of water spray should be increased gradually.

Management and harvesting of Straw Mushroom

1. It only takes about 12 days from sowing to harvesting straw mushroom. Straw mushroom grows fast and is easy to open umbrella. in order to harvest in time, the suitable time for harvest of commercial straw mushroom is long buds and unopened umbrellas. During the peak production period, 2ml should be harvested three times a day. When harvesting, hold down the culture material with one hand and gently unscrew the fruiting body with the other, so as not to hurt the immature buds. For the mushrooms picked, the rotten grass and sediment at the base of the fruiting body should be removed with a sharp knife and sent to the market in time for fresh sale. In addition to fresh sales, it can also be processed into dried straw mushrooms and canned straw mushrooms.

2. After the first batch of mushrooms is picked, the second batch of mushrooms will usually be produced in 4 days. If the mushrooms are properly managed, they can be collected in 2 / 3 batches. But it is mainly the first batch of mushrooms, and generally the output of the first batch of mushrooms accounts for about 80% of the total output. Some mushroom houses usually harvest only one batch of mushrooms in order to improve the utilization rate of mushroom beds.

In fact, as long as you master good technology, it is very easy to grow straw mushrooms. It is necessary to understand the growth habits of volvariella volvacea before planting, and then cultivate them at the right time. In the later stage of cultivation, it is necessary to do a good job in mushroom production management, so as to ensure its growth. Attention should also be paid to the methods when processing and harvesting.
