Choose a flat site, dig a bed with a depth of 30cm, a width of 1m and an unlimited length. The bed bottom is slightly turtle-backed, with a distance of more than 80cm between beds, and leave a good drainage ditch. The bed was first sprayed with 1000 times dichlorvos to kill insects, and then disinfected with 5% lime water. Wrap the plastic bag with good bacteria, and lay the rods horizontally in the bed, with a distance of 2-3 cm between them, and fill the bed.

Cover the sterilized soil covering material on the fungus stick and water it once. At this time, the soil will inevitably sink between the fungus sticks, and it will be paved with soil again, and then watered until all the fungus sticks are muddy.

Spread a layer of covering soil with a thickness of 4-5 cm on the fungus stick, and water it evenly until the covering soil layer is completely permeable, and the covering work is over. If the bed is built outdoors, a small arch shed should be set up and covered with plastic film or grass lotus and other shade objects. Generally, mushrooms can grow in 7- 10 days.

2. Management of fruiting period

In the fruiting period, the management mainly focuses on moisturizing, and at the same time, it gives scattered light and provides fresh air, so that the original base can occur as soon as possible. The method of covering the soil to grow mushrooms is very simple to manage before growing mushrooms. If the temperature is suitable, buds can appear almost without water supply, but the temperature difference between day and night should be widened and scattered light should be given to stimulate them.

For the young mushroom period, the ventilation should be slowly increased to prevent the emergence of long-legged mushrooms, and water should be sprayed 1-2 times a day, which should be lightly sprayed and swept by to keep the mushroom cover moist.

If there is water on the surface of young mushrooms or the difference between water temperature and greenhouse temperature is more than 10 degrees, young mushrooms will shrink and die. During the period after the young mushroom is formed, its growth is accelerated, its resistance to adverse environment is gradually strengthened, and the demand for moist fresh air is also increased, so it is necessary to ventilate and replenish water for many times every day.

3, timely harvesting

The Pleurotus ostreatus can be harvested when the cap is slightly flat. Spray heavy water once before harvesting, gently insert your hand into the root of the fruiting body, shake it off with a little force, and then scrape off the soil or material at the root with a knife. After harvesting, it is necessary to clean up the covering soil surface and dispose of residual roots and debris. After drying for 2 days, replenish water in time and enter the management of the second tide mushroom.

Secondly, nutrient solution can be added when the mushroom is replenished with water. 0.3% magnesium sulfate, 0.1%white sugar, 0.3% potassium dihydrogen phosphate, 0.1%mushroom rich element. In the process of mushroom growth, if there are pests, dichlorvos can't be sprayed, because all kinds of mushrooms have strong allergic reactions to the medicine, and all the mushrooms die after spraying, so only special mushroom pesticides can be used.

Extended data:

There are many nutrients available to Pleurotus ostreatus, and both woody and fibrous plant residues can be used. In artificial cultivation, waste cotton, cottonseed hull, corncob, cotton stalk and soybean stalk have higher yield in turn, and other agricultural and forestry wastes can also be utilized, such as sawdust, straw, wheat straw and corncob.

The mycelium growth temperature range and suitable temperature of different species are not completely the same. Most species and varieties can grow at 5 ~ 35℃, and 20 ~ 30℃ is the same suitable temperature range for their growth. The optimum growth temperature of low-temperature and medium-low temperature varieties is 24 ~ 26℃, the optimum growth temperature of medium-high temperature and wide-temperature varieties is about 28℃, and the optimum growth temperature of Pleurotus ostreatus is 25 ~.

The optimum water content of substrate for mycelium growth is 60% ~ 65%. When the water content of substrate is insufficient, the fungus will grow slowly and the fruiting will be delayed after the fungus growth is completed. Raw material cultivation, when the water content of the substrate is too high, has poor air permeability, slow mycelium growth, and is easy to breed anaerobic bacteria or molds.

The optimum fruiting period is 70% ~ 75%. When the atmospheric relative humidity is 85% ~ 95%, the fruiting body grows rapidly and vigorously. When it is lower than 80%, the mushroom cap is easy to dry or crack, and when it is longer than 95%, it is easy to appear rotten mushrooms. In the cultivation of raw materials, the method of partial drying and supplementing water during the fruiting period is often adopted to ensure that the fungus is not infected by mold during the fruiting period and that there is enough water for the mushroom during the fruiting period.

Pleurotus ostreatus is an aerobic fungus, and its mycelium can grow normally under the cover of plastic film, and it can also grow normally in a strain bottle sealed with plastic film. The mycelium grows better at a certain carbon dioxide concentration than at normal carbon dioxide content in natural air.

A certain concentration of carbon monoxide can stimulate the growth of Pleurotus ostreatus mycelium, but the formation, differentiation and development of fruiting body need sufficient oxygen. When oxygen is insufficient and carbon dioxide concentration is too high, it is not easy to form fruiting bodies.

The growth of Pleurotus ostreatus mycelium does not need light, but light inhibits the growth of mycelium. Therefore, dark or weak light environment should be given during fungus growth. However, the occurrence or growth of fruiting body needs light, especially the formation of fruiting body primordium.

In addition, the light intensity also affects the color of the fruiting body and the length of the stalk. In contrast, under strong light conditions, the fruiting body is darker in color, shorter in stalk, thicker in meat and better in quality; When the light is insufficient, the fruiting body has light color, long stalk, thin meat and poor quality.

Pleurotus ostreatus mycelium can grow in the range of pH 3.5-9.0, and the suitable pH is 5.4-7.5. In cultivation, after the natural culture medium and natural water are mixed, the pH of the substrate is mostly 6.0-7.5, which is suitable for the growth of Pleurotus ostreatus mycelium. However, in practical cultivation, quicklime is often added to raise the pH value to 7.5-8.5, so as to inhibit mold growth and ensure fungus growth.
