It is suitable to cultivate these edible fungi in summer.

Agaricus tetrasporus, also known as Pleurotus ostreatus, is a medium-temperature edible fungus. The suitable temperature for mycelium growth of this variety is 20 ℃ ~ 34 ℃, the optimum temperature is 25 ℃ ~ 27 ℃, and the suitable temperature for fruiting body growth and development is 27 ℃ ~ 29 ℃. Higher than 30 ℃ or lower than 26 ℃ is not conducive to mushroom emergence. According to the suitable temperature range of this variety, the cultivation method of sowing in summer and producing mushrooms in early autumn is the most suitable, which can not only make use of its characteristics of high temperature tolerance, but also produce a large number of mushrooms on the market in the off-season of edible fungi in early autumn to fill the gap in the market. improve production efficiency.

The cultivation and management of Agaricus bisporus is basically the same as that of Agaricus bisporus. The main raw materials are wheat straw, cow and pig manure, indoor bed frame cultivation and outdoor greenhouse cultivation. Because the mushroom production period is relatively short, generally only 3-4 stubble mushrooms can be harvested, so the bed culture material should not be too thick, about 12 cm is appropriate. The temperature control and water management in the mushroom stage are very important, and it is the top priority to win high quality and high yield. As long as the technical measures of each production link are managed in place, it can generally produce 6.5 to 7.5 kilograms of fresh mushrooms per square meter, with an income of 50 to 60 yuan, which is a reliable variety for mushroom farmers to skillfully use the off-season sales of edible mushrooms to increase their income.

Volvariella volvacea is a high-temperature edible fungus, which is very sensitive to temperature in its growth and development. In order to make volvariella volvacea grow normally after sowing, it should be cultivated when the daily average temperature is above 23 ℃. It is generally cultivated from the first ten days of June to the end of August, which is beneficial to the growth of mycelium and the development of fruiting body. Straw mushroom can be cultivated indoors and outdoors, but outdoor cultivation is more favorable. When cultivated outdoors, the farmland with fertile, loose, breathable soil and convenient drainage and irrigation should be selected, and the previous crops had better be rape and watermelon. Weeds should be removed and furrows should be made before cultivation to ensure that they can be drained during waterlogging and irrigated in times of drought.

No matter which kind of raw material is selected to cultivate straw mushroom, the raw material should be exposed for 2-3 days before production to ensure that the raw material is dry without mildew. The newly harvested straw must be thoroughly dried, otherwise it will spoil easily. Before sowing, pre-wet the material with 5% lime water to make the pH value above 12, and then build a heap for fermentation for 4-5 days, and the water content of the culture medium should be kept at 65%-70%.

The selection of bacteria is very important in production. The selection of high-quality and high-yield strains can obviously improve the yield and quality of volvariella volvacea, and volvariella volvacea V23 and V238 are ideal. Properly increasing the amount of sowing can accelerate the growth of mycelium and inhibit the occurrence of miscellaneous bacteria.

The practice has proved that it is difficult to obtain high yield by traditional pile cultivation, border cultivation and bed cultivation, because the temperature and humidity can not meet the requirements. On the other hand, the "two-stage cultivation method" of planting bacteria in bag and then covering soil in plastic arch shed or vegetable greenhouse can obviously increase the yield of straw mushroom.

The cultivation of volvariella volvacea is in the high temperature season. In the management, special attention should be paid to the relationship between temperature and humidity, and the cooling, humidification, ventilation and shading should coordinate with each other to avoid the death of mushrooms caused by improper treatment. When covering the soil, the bacterial bags should be placed flat, the distance between the bags should be 5: 10 cm, the space should be filled with soil, and the surface soil should be 1.5-2 cm thick. After covering the soil, the mycelium should be fully watered, so that the hyphae can make full use of the soil moisture. In water management, one is not to replenish water when the fruiting body is formed, and the other is to directly replenish tap water or underground well water, so as not to cause large temperature difference and lead to dead mushrooms in batches.

Abalone mushroom is a kind of medium-high temperature rare edible mushroom, the mushroom period is in the off-season of edible mushroom sales, coupled with this variety of meat thick and resistant to transport, with a unique abalone flavor and excellent taste, the market price is high.

From March to July, cotton husk, corncob, sawdust and wheat straw were selected as raw materials and planted in clinker bags to cultivate abalone mushrooms. Generally, 4-5 crops of mushrooms could be harvested, with a bioconversion rate of 90%, 1000 kg of raw materials, and 900kg of fresh mushrooms in 3 months. it is a reliable way for mushroom farmers to increase their income in the off-season of edible mushroom sales.

High temperature Pleurotus ostreatus can produce mushrooms normally at the temperature of 15 ℃ ~ 36 ℃, which is called high temperature Pleurotus ostreatus. There are Gaoping 1, three Gorges 13, Pleurotus ostreatus, delicious Pleurotus ostreatus and so on. After May every year, the supply of fresh mushrooms on the market will be less and less, especially from June to August, except for a small number of straw mushrooms and high-temperature mushrooms on the market, other edible mushroom varieties are very rare. this provides a very favorable market space for producers to develop high-temperature Pleurotus ostreatus. The cultivation of Pleurotus ostreatus in high temperature season has the advantages of short production cycle, large market demand and high price, which can not only meet the market demand, but also increase the income of mushroom farmers.
