Construction technology of Pleurotus ostreatus production shed in western Liaoning
I. the advantages of cultivating Pleurotus ostreatus in plastic greenhouse
1. The greenhouse is made of soil or brick, covered with no dripping film for roof, and covered with grass curtain. In the severe winter December and January of the following year, the greenhouse can keep more than 8 ℃ ~ 24 ℃, which is not lower than the lower limit temperature of Pleurotus ostreatus fruiting body growth, which can make New Year's Day and Spring Festival fresh aunt go on the market as usual. In Damiao Town, it can be used all the year round to ensure that the mushroom can be produced all the year round and will not affect the production.
two。 Ventilation and light transmission is easy to adjust the back wall of the shed has several ventilation holes, which are usually plugged with grass or other wastes. When ventilating, remove the ventilation, cover the roof with the grass curtain, and adjust the grass curtain properly, you can achieve the effect of adjusting the light intensity.
3. The cost is low to build a plastic greenhouse with a width of 7.5m and a length of 50m (except for nursing houses), with a total investment of about 7500 yuan.
II. Construction of plastic fire shed
1. The site should choose the land with high and dry terrain, flat, leeward to the sun, close to the water source, and no pollution source around to build the fire shed.
two。 The plastic greenhouse is 7.5 meters wide and 50-80 meters long. The width of the base of the back wall is 1.3 meters, the width of the top of the back wall is 0.80 meters, and the height of the back wall is 2.2 meters (with the earth wall as the standard). The length of the platform shed is 1.6 meters, and the platform shed is at a horizontal angle of 30 degrees with the back wall. The top of the spine is 2.7 meters to the ground and the aisle is 0.80 meters.
3. After the construction procedure determines the location of 7.5 m x 50 m, the soil in the planned shed is dug loose (or borrowed soil) and watered. After the water permeates, sprinkle a layer of short straw, chop the grass and mix the soil, use the grass mud to build a wall, the gables at both ends are semicircular, and leave the door at one end of the gables. After the wall is dry, the platform shed is built with wood and so on. Use 4 steel corners, east-west as crossbeams, and then use bamboo pole north and south as brackets, laying on the steel corner lines, the front shed angle is 65 degrees. No drip film 4 meters wide, two greenhouse films 8 meters wide are compacted with soil on top of the bamboo pole, and the film is covered with grass curtains.
4. The bottom width of the platform is 0.5 meters, the height of the platform is 15 centimeters, the width on the platform is 0.4 meters, and the distance between the two platforms is 0.80 meters.
5. Repair the cold-proof ditch 30 cm away from the bottom corner of the front shed, dig a cold-proof ditch 30 cm deep and 30 cm wide, and fill the ditch with weed straw in winter to protect against the cold.

Technology of Pleurotus ostreatus under forest
First, to ensure the quality of strains, it is very important to master the correct production technology and ensure the good quality of Pleurotus ostreatus in order to achieve high and stable production. The variety we choose is Pinggao No.1. Practice has proved that the yield of improved varieties is more than 30% higher than that of inferior varieties, and the mushroom is strong, and diseases and insect pests rarely occur. Second, the high-temperature Pleurotus ostreatus production site is selected as the woodland arch shed. The requirement is good ventilation and convenient drainage. Third, the production of bacterial bags can adopt the method of making bags with clinker instead of raw materials. Clinker cultivation means that the culture materials are sterilized at high temperature before entering.

Benefit technique of interplanting Pleurotus ostreatus in Pear Orchard
After the pear trees are harvested, the pear orchards have a long leisure time. Planting Pleurotus ostreatus in one season by using the empty rows among the pear trees can obtain better economic, ecological and social benefits. A nursery bed of about 10 square meters can produce more than 100 kilograms of Pleurotus ostreatus with an income of more than 200 yuan, with less input and quick effect; it can also increase fertilizer sources, improve soil fertility, improve soil fertility, increase the content of phosphorus and potassium, and kill winter weeds; it is beneficial to the secondary rooting of pear trees in autumn. In order to interplant Pleurotus ostreatus in pear orchard, the following points should be mastered in planting techniques. I. choose the location of the bed
