The latest course of cultivation techniques and methods of Pleurotus ostreatus

Pleurotus ostreatus, also known as white mushroom, is a kind of edible mushroom with the highest yield and the most consumption in the world. China's cultivation is mainly for export, but with the increase of domestic consumption, the market prospect is good. In addition, Pleurotus ostreatus has high nutritional value and health care function, the market demand is large, and the investment is less and the effect is quick. Let's go with the editor to understand how Pleurotus ostreatus is cultivated.

1. Mushroom shed management

The mushroom shed had better be built in a place with flat terrain and abundant water, and it should be far away from warehouses, chemical plants and other places, sitting north and facing south, which is conducive to warming in winter. The temperature of the mushroom shed is too high or too low, too much water content, water seepage and other factors, so the pressure of the mushroom shed should be well ventilated, and all doors and holes must have doors, so that they can be ventilated and closed so that the temperature and humidity can be controlled. At the same time, screens should be installed on the doors and holes to prevent mosquitoes and flies from entering. The roof is covered with a layer of black film, covered with a layer of 30cm straw, and covered with a layer of film, which is conducive to heat preservation.

2. Raw material formula

The cultivation raw materials of Pleurotus ostreatus are mainly rice straw and cow dung, and dried cow dung is better. Take one per square meter as an example, generally use 1300 kg of dried rice straw, 500kg of dried cow dung, 350kg of dried chicken manure, 17.5kg of urea, 75kg of cake fertilizer, 25kg of phosphate fertilizer, 17.5kg of lime and 17.5kg of gypsum as the formula. At this time, the pH value of the culture material is about 7.5-8. Or use 500kg of dried rice straw, 1250 kg of dried cow manure, 1250 kg of dried chicken manure, 40kg of phosphate fertilizer, 40kg of calcium carbonate and 50kg of lime as the formula, and the pH value is about 7.5-8.

3. Compost fermentation

First of all, the straw is soaked in water in batches, stirred while soaking, so that it can be fully absorbed by water, and then stacked together layer by layer. After pre-stacking, there will be water abortion. On the 3rd day after pre-wetting, spread a layer of pre-wet straw, sprinkle lime powder on the surface, spray water once, spread urea and lime powder on the surface, and then spread a layer of straw, and so on, until the pre-pile is finished. Before building the pile, cow dung, chicken manure and fertilizer are crushed and mixed evenly, then pre-wet with low concentration of lime and kneaded into a ball, then phosphate fertilizer, gypsum and lime are crushed and mixed evenly, sprinkled on the noodles of cow and chicken dung, mixed well and covered with plastic film. Fermentation is carried out on the fifth day of the pre-heap of straw, spread the straw on the ground, and then sprinkle a layer of mixture of cow dung and chicken dung on the surface, and so on, until the pile is completed. Finally, spray water to turn the pile, measure the pH, make a suitable culture material, the final culture material water content of about 64%, pH 7.5-8, no sour smell, but also has a special flavor.

4. Sowing seeds

When sowing, the bacteria container, the inoculation basis, and the operator's hands should all be sterilized with alcohol. First, spread half of the bacteria evenly on the material surface, and then insert the bacteria into the material surface with fingers for a little suppression, so that the bacteria fall evenly into the 3-5 material surface of the material. Then spread the remaining half of the bacteria evenly on the material surface. After sowing, the temperature should be maintained at 22-25 degrees and the air relative humidity should be 75%. Within one week of sowing, the vents should be closed in time to allow the bacteria to germinate and colonize as soon as possible. after a week, the mycelium grows normally and can be ventilated normally.
