A New way for High yield of Pleurotus ostreatus-- High benefit of three-dimensional cultivation in semi-basement
The cultivation of Pleurotus ostreatus with three-dimensional bed frame in semi-basement is a new way to win high yield and improve economic benefit in recent years. According to the experiment, the annual output of Pleurotus ostreatus is about 2500 kg with an input of 2000 kg on an area of 20 square meters, and its biological efficiency is more than 120%. The main technical points are as follows:
1. In order to build the greenhouse, we should first dig a pit with a depth of 1.8 meters ~ 2 meters and a width of 4 meters ~ 5 meters. Its length is determined according to the need and put into a three-dimensional bed frame. It is arched with bamboo poles and thin film, compacted with soil and covered with grass. There are about 30 square centimeters of vents in the east, west, north and south, and a small door is built in the west to facilitate the entry and exit of the staff.
two。 Formula of inoculation culture material: 100 kg of cotton seed shell, 120 kg of water, 1 kg of gypsum, 0.1 kg of wettable carbendazim powder. Mix well and accumulate and ferment. Then, vaccinate the sterilized house. The four-layer inoculation method was adopted and the amount of inoculation was 15%.
3. Put the inoculated bacteria bag in a room with good insulation. When the room temperature is slightly lower, stack 5 ~ 6 layers, and when the room temperature is slightly higher, stack 3 ~ 4 layers. Pour the bag every 5 to 6 days and check the temperature in the pile frequently to prevent high temperature burns. The room temperature was controlled at about 20 ℃ and the hyphae could be filled in about 20 days.
4. Strengthen the management to move the mycelium bag into the greenhouse in time and put it on the three-dimensional bed frame. The 4-meter-wide greenhouse can hold 3 rows of bed frames, with 9-10 layers of bacterial bags in each row. After setting it up, strengthen the ventilation, adjust the temperature difference between day and night, and the seed entity primordium can be formed in 4 ~ 6 days. Open the bag mouth to the mulberry stage, spray water on the ground or wall, keep the air relative humidity about 90%, pull up the bag mouth to the coral stage, so as to smoothly produce mushrooms, and harvest in time when medium well. After picking the second crop, soak the bacterial bag in water for 5 ~ 6 hours, then tie the mouth and put it on the bedstead, you can also harvest 1 ~ 2 tides.
Pleurotus ostreatus semi-basement three-dimensional bed frame cultivation can make better use of natural light and temperature, better heat preservation and moisturizing effect, does not occupy cultivated land, can be cultivated in general courtyard, and can be cultivated in all seasons of the year. High output and good economic benefit.

Rapid cultivation of Pleurotus ostreatus in high temperature season
High temperature is extremely disadvantageous to the normal growth and high yield of Pleurotus ostreatus. If conventional cultivation methods are still used, not only the cost is high, but also the yield is low. However, if the rapid high-yield cultivation technique is adopted, high yield and high efficiency can be obtained. Summing up our experience for many years, the main points of rapid and high yield cultivation of Pleurotus ostreatus in high temperature season are as follows: there are many varieties suitable for Pleurotus ostreatus, and the quality of pure high temperature type is poor, so it is suitable to choose wide temperature but high temperature tolerant varieties. Such as Su Ping, Ai Kang 558, West Germany 33, Yaguang 1 and Gaoping 1, three Gorges 13.

After the additional nutrient solution is harvested, soak the bacterial bag in nutritious water with 0.1% urea and 3% sugar for about 10 hours, and a large amount of water can be inhaled, and the two-tide mushroom will form quickly; then use the water dispenser to inject the nutrient solution (vitamin B1, 20 mg, 20 g magnesium sulfate, 5 g boric acid, 10 g zinc sulfate, 25 g urea, 50 kg cold boiled water), dehumidify and keep warm for 7 days. Or pound the skin at both ends of the bag, stand upside down on the ground and fill it with nutrient solution water (vitamin B).
