1. Prepare the culture material and formula. Based on the cultivation of 1m2, it is necessary to prepare 15kg of high-quality dry wheat straw, 6kg of dry cattle manure, 5kg of phosphate fertilizer and 25kg of urea.
ii. composting and turning over of culture materials
(1) The whole process of composting culture materials takes about 25 days, and the stacking time is 5 days before sowing.
(2) Stacking and turning. The cultivated material pile is made in a place where there is no water, no pollution and water. 2-3 days before the pile is built, take out the wheat straw after soaking in water, evenly sprinkle 1.5 lime powder layer by layer, then pile the wheat straw into a rectangular pile, layer by layer, and at the same time pre-wet the horse manure; When building a pile, first spread a layer of wet wheat straw in the pile yard, with the thickness of 15-2 cm, and then sprinkle a layer of manure on the wheat straw, with a total of 1-12 layers. From the second layer, add a proper amount of water and turn over the pile in four times, the first time on the seventh day after building the pile, and then every time after 5-6 days, each time turn over the pile in strict accordance with technical requirements.
third, sowing
(1) sowing time: the outside temperature is about 25℃, and the material temperature is below 28℃, which is suitable for sowing. According to the temperature situation in our city, September 5 is suitable at present.
(2) sowing amount: 5g/ bottle per m2.
IV. Management before covering soil after sowing
(1) After sowing, the relative humidity is kept at about 8%. If the material temperature exceeds 28℃ and the temperature in the shed exceeds 3℃, properly ventilate and cool down.
(2) within 4-1 days after sowing, it is necessary to ventilate slightly in time. If the humidity is about 7%, which is low, paper can be used to cover the material surface, and then 1% lime water is sprayed on the paper until the paper is wet without water accumulation.
(3) Take off the paper in time after 1 days of sowing, and cover the soil after 15-2 days when the mycelium is basically full of material layers.
V. Covering soil and management after covering soil
(1) Covering soil: 2.5m3 soil is needed according to 1m2, 5kg phosphate fertilizer and 1-2 lime powder are mixed in the soil, and it is advisable to infiltrate with water, grab it and scatter it, and spread the soil evenly on the material surface with a thickness of 2-2.5cm..
(II) Management after covering soil
1. Moisture content: The moisture content of the covering soil layer is generally 2%, and when the mushroom buds grow into rice grains, they are sprayed out of the water once.
2. Humidity: The humidity of the space is required to be between 8% and 9% after covering with soil.
3. temperature: the optimum temperature for mycelium growth is 13-18℃, and the optimum temperature for solid growth is 13-18℃.
4. timely harvesting: the harvesting diameter is 2-4cm.
experts predict that the price of edible fungi in our province will continue to rise this year, but Pleurotus ostreatus will gradually be replaced by Pleurotus ostreatus, Pleurotus ostreatus and Pleurotus nebrodensis, mainly because the quality of Pleurotus ostreatus is declining, and the price may drop slightly. However, some edible fungi with good taste and high nutritional value, such as Pleurotus eryngii, Pleurotus ostreatus, Pleurotus nebrodensis and Agrocybe aegerita, will be greatly welcomed by consumers, and the sales volume will definitely double that of 25, especially the market share of Agaricus bisporus will increase greatly, and there will be a good harvest when rare edible fungi are planted. At present, the wholesale price of Agaricus bisporus is between 2.7~3.5 yuan/kg.
