First, the culture material formula
5,000 kg of wheat (rice) grass, 2500 kg of dried cow dung, 400 kg of dried manure, 75 kg of cake fertilizer, 75 kg of urea, 75 kg of ammonium bicarbonate, 75 kg of phosphate fertilizer, 100 kg of gypsum, 125 kg of lime, 6 kg of formaldehyde, 6 kg of formaldehyde, 1.5 kg of dichlorvos .
Second, the pile up method
The site of the pile should be selected at a higher terrain, closer to the mushroom house and water source. The north and south of the pile can make the sunshine uniform and beneficial to fermentation; in order to reduce the labor intensity, the manure and cake fertilizer are added when the first turn. When building the pile, only the wheat straw is soaked in water, and a layer of 2-2.5 m wide and 25 cm thick grass is laid on the front. The length depends on the cultivated area, and one layer is piled up, and one layer of water is poured. Stack up, pile 10-20 layers, stack height 1.5 meters, the pile is vertical around, the top of the pile is arched, there is water seeping after the pile, not enough to replenish water the next day.
In order to make the manure fermentation evenly, it should be turned over every few days. The interval between each pile is 7 days, 7 days, 6 days, 5 days, 3 days. The whole stacking time is about 26 days, and the straw is shortened. The day is 23 days. The pile is required to be turned upside down, turned upside down, turned inside and inside, and the manure is fully shaken and filled with water. The first turnover must be carried out 7 days after the pile is built. The shape of the method is the same as that of the pile, and the cow dung, cake fertilizer, water, and layers are added in the previous day, and the bottom is less, the upper part is more, and the culture material can be gripped by hand. It is advisable to drop 6-7 drops of water. The second turn was carried out 7 days after the first turn, the pile shape was reduced, the height was unchanged, and the ammonium bicarbonate was mixed when the pile was turned over. The grass layer was added, and the water content was 4-5 drops, and it was not enough to replenish water. After the third turn over 6 days from the second turn, mix the manure with the mixture, add gypsum, lime powder, insufficient stack temperature or lack of manure, cake fertilizer, can be added to the wheat bran, water 2-3 drops. The fourth turn was carried out 5 days after the third turn, and each layer was evenly sprayed with 0.2% dichlorvos and 1% formaldehyde mixture. Adjust the water content to about 65%, that is, it is better to drop 1-2 drops of water by hand pressing the culture material, the pH value is 7.5-8, the material pile is widened to reduce the edge material, and 2-3 days after the fourth turnover Can enter the shed, the day before entering the shed, use the mixture of dichlorvos and formaldehyde to spray wet, then cover the film and seal it for a day and night.
During the stacking process, it must be wet and dry first. The straw has less water consumption. After the first flooding, if it encounters heavy rain, it needs to be covered with film, and the rain will be removed in time to facilitate ventilation.
Third, build shed and sowing
Choose a high-altitude field, bamboo raft shed, shed 1.7 meters high, 5-6 meters wide, covered with film, shed trench film around the shed, shade with corn stalks and straw, north and south of the greenhouse is good, shed length 20 -40 meters is appropriate. The day before the feed, spray the mixture with formaldehyde and dichlorvos, spray a layer of lime, and disinfect the insects.
The culture material is heated into the shed, piled into small sputum, and the two ends of the shed are closed to promote warming and sweating. The next day, the material was mixed and loosened, so that the dung grass was evenly mixed, paved into sputum, and the thickness was 20 cm. The wheat germs in the bottle were scattered, evenly spread on the surface, gently flattened, and then covered 1 cm. Broken culture. After sowing, the temperature in the shed exceeds 30 °C. At noon, it is necessary to spray water to the top of the shed to cool down. The film at both ends of the shed moves up and down to cool down with the temperature.
Fourth, Daejeon Management
14-18 days after sowing, when the hyphae penetrated into the material 2/3, the soil was covered. If there is a pest or disease hazard before covering the soil, it should be covered in time after curing. The soil particles can be taken locally, using the aisle to excavate the soil, according to the standard of 0.6 kilograms per 100 kilograms of soil plus lime, mix the soil particles, adjust the water content, make the soil knead into a mass, mix and open, and restore the material surface at one time. 3-4 cm. The plastic greenhouse has a quick return to the ground, and the film has good moisturizing properties. When the soil is covered, the water is well grasped. Generally, it is not necessary to spray water. Only a small amount of water is sprayed in the ventilation place at both ends of the greenhouse until the mushroom is released.
18-20 days after the soil is covered, small mushrooms appear one after another, the mycelium of the soil is white, and the temperature of the shed falls below 22 °C. It is stimulated by the temperature difference between the morning and the evening or the cold air south, and the water is stimulated. The plastic sheds are planted with Agaricus bisporus. Generally, the water is only transferred when the head is 2-3 ,, and then it is necessary to stop the water until winter. Each time the water is sprayed, it is mainly close to the air outlet at both ends of the greenhouse, with less spray in the middle and no spray in the wet place. Note that the hyphae cannot be destroyed by excessive water spray. It is necessary to pick the mushrooms in time, and the harvesting standard is 4-5 cm in diameter, and the surface is cleaned in time after harvesting.
