High-yielding cultivation techniques of two Tides of Pleurotus ostreatus

1. in that past, most of the mushroom shed used for mushroom shed treatment were simple greenhouses with single slope or semi-underground simple greenhouses, and it was difficult to use sunlight to increase temperature in low temperature season, so that after cultivation and production entered November, the temperature of the shed decreased with the temperature, and when the lowest temperature of the shed reached 8℃, the mushrooms would no longer be produced, and only after the temperature rose again in March of the next year could the mushrooms be produced again, which would certainly prolong the fruiting period. After the mushroom shed was reconstructed to imitate winter warm or sunlight warm (winter warm), the low temperature time of more than two months from the middle of December to the last ten days of February could be fully utilized for mushroom production, and the mushroom production time was prolonged. The basic practice is: first according to the production plan to rebuild the original shed or directly new, wall thickness is not less than 0.8 meters, the highest part of the shed is not less than 2.5 meters, generally about 40 meters long, 6 meters wide-7 meters is appropriate, using "two films and two covers" cover, hanging a layer of black plastic film in the shed, so that when the cover is uncovered in the low temperature season, heat can be allowed to enter without direct sunlight. Secondly, according to the cultivation bed line digging ditch, generally north-south to the bed width of 1.2 meters, operation channel width of 0.4 meters-0.6 meters, the operation channel digging depth of about 0.2 meters, close to the south can gradually deepen, bed slightly turtle-back shape. Third, disinfection. New mushroom shed can be sprayed with 40 - 60 times mushroom disease-eliminating king solution and 600 times dichlorvos solution, and then closed mushroom shed, two days later can be used. Reapply the pesticide once every other day in the reconstructed shed to strengthen the disinfection and insecticidal effect. Finally, the shed is watered. About 5 days before feeding and sowing, irrigate the shed and allow it to flow naturally to make the land fully irrigated. One is to increase the humidity in the shed, and the other is to reduce the temperature of the shed. 2. Cultures are processed according to the preparation or storage of raw materials, and the appropriate formula is selected. Two formulas are provided for selection: ① Formula 1: wheat straw 3000kg, cow dung 3000kg, calcium superphosphate 60kg, urea 60kg, lime powder 80kg, gypsum powder 80kg, light calcium carbonate 90kg, bean cake powder 100kg, edible fungi three-dimensional nutrient essence (mixed type) 10 bags. (2) Formula 2: corncob powder 2000 kg, cottonseed hull 2000 kg, cow dung 2000 kg, calcium superphosphate 80 kg, urea 40 kg, lime powder 60 kg, gypsum powder 80 kg, light calcium carbonate 50 kg, bean cake powder 60 kg, edible fungi three-dimensional nutrient essence (mixed type) 12 bags.
