The cultivation of Pleurotus ostreatus requires a mushroom house, which is not planted in the open air. It is better to choose a dark basement. The area of each mushroom house is 15 square meter, which is too big to manage and too small to manage. Such an area is conducive to drainage and lighting. In order to avoid the infection of miscellaneous bacteria, the walls of the mushroom house need to be wiped with lime water. Nowadays, the cultivation and management of Pleurotus ostreatus are all based on bedsteads, and it is appropriate to leave a width between two bedsteads that one person can easily walk through, which is convenient for daily work and picking Pleurotus ostreatus.
Second, the disinfection work before planting:
Pleurotus ostreatus is a mushroom and a fungus, so the disinfection work should be done well, otherwise it will be easy to be infected with miscellaneous bacteria, so planting Pleurotus ostreatus is very important for the disinfection of mushroom houses. It is better to disinfect the mushroom house with potassium permanganate solution of 1000 times. Spray the mushroom house with a special sprayer. After the spraying work is completed, it needs to be sealed for about 12 hours to completely kill germs.
Third, the cultivation method of Pleurotus ostreatus:
In the cultivation of Pleurotus ostreatus, crop wastes such as sawdust, grain shells and melon seeds shells are selected as the culture medium of Pleurotus ostreatus, which is commonly called mushroom bed, and then the prepared strains are spread on the mushroom bed, covered with auxiliary materials such as wheat flour and gypsum, and finally covered with a breathable film.
Within one week of planting, the temperature of the mushroom house should be controlled at about 10℃. When white spots are found on the strains, the breathable film should be removed, and the indoor temperature should be raised to about 22℃. During the cultivation period, the mushroom bed should always be kept in a moist state, and the air humidity should be above 80%. When Pleurotus ostreatus is in full bloom, the cooked farmyard manure for people and livestock is diluted and dripped on the fungus bed.
Four, Pleurotus ostreatus harvesting technology:
When the Pleurotus ostreatus grows into an embryonic form, the color will change from white to gray, and it can be picked when the mushroom flap is the size of a palm. Pull out the stem of Pleurotus ostreatus by hand, and quickly cut off the Pleurotus ostreatus with scissors, leaving small Pleurotus ostreatus around. After 10 days, you can continue picking, and the number of continuous picking can reach about four times.
Key points of cultivation techniques of Pleurotus ostreatus:
1, there are many cultivation bases for Pleurotus ostreatus, and many rural straws and wastes can be used as cultivation bases for Pleurotus ostreatus, but most growers still use straw and cotton seed shells as cultivation raw materials for Pleurotus ostreatus, which can also be used flexibly.
2. The step of cultivating and sterilizing Pleurotus ostreatus is very important. The width of the feed bag is 22-25 cm, and the plastic wrap is of good quality. Cut it into plastic tubes of 40-50 cm, put the culture material in the bobbin, sterilize the bag in a steamer, and steam it in 100 degree steam for about ten hours.
3. The production of Pleurotus ostreatus culture medium is not very complicated, and the technology is simple. Prepare the culture medium with the ratio of dry material water 1: 1.5, and then test the water content of the culture medium. The method is to pinch the culture medium tightly by hand. If there is water but it can't drip out, it means that the water is added just right.
4. Inoculation of Pleurotus ostreatus is a delicate job. The method is to take out the strains in the bottle with tweezers and put them in a bag. Just put three strains the size of soybeans in one mouth, which is a big waste of strains. It is worth noting that tweezers should be disinfected to avoid contamination failure caused by bacteria. Disinfection can be smeared with alcohol or potassium permanganate. When inoculation, you should be calm and try not to make any noise or talk, so as to avoid all the possibility of bacterial invasion.
5. Protect the mycelium. After planting, put the plastic bag in a ventilated place to let it grow slowly. In winter and early spring, it can be put in double rows, and then cover the plastic wrap, or cover the straw curtain. It can not be double rows in autumn or late spring, but only single rows.
6, the final management and protection work should also be done well. When the hyphae inside are full, they can be taken to the mushroom room, and then they can be placed in a single row, with an interval of 80cm between each row, and the air can be changed for an hour every day to maintain the air freshness of the mushroom room. You can use a spray pot to spray water to increase the air humidity.
