Time-saving, efficient coprinus comatus cultivation technology

In recent years, due to the market conditions of edible fungi, the cultivated area of ​​Coprinus comatus in Shandong has been continuously expanded, and the cultivation technology has also been continuously innovated. Introducing the innovative technology of a pioneering, labor-saving, time-saving and efficient cultivation of coprinus comatus for the exchange.

1. The choice of cultivation strains of good varieties and the quality of their strains directly affect the yield of Coprinus comatus. It is very important to choose a good variety and pay attention to replacement.

2. Formula of culture materials and preparation of cultivation bags: 40%-50% of new cotton shells, 30%-40% of oyster mushroom or mushroom, blanco 10%, urea 0.5%, lime powder 2%-3%, Material: Water is 1:1.2-1.5. Mix regularly and pile up the fermentation. When the culture material becomes slightly reddish-brown, there is a fermented aroma and when the inner surface has white actinomycetes, the fermentation ends. Material temperature dropped below 30 °C bagging. For the cultivation bag, a 45 cm 24 cm 0.02 cm polyethylene film cartridge was used. The seed amount was 25%, and 4 layers were sown. The bag was punched in the middle. Bacteria packed in 20-25°C latrine culture, pay attention to ventilation about 20 days full bag, when the mycelium is slightly sparse, gray, continue to culture for another 15 days or so, mycelium mycelium is dense, white At this time, it can reach the physiological maturity can be covered with soil cultivation.

3. Greenhouses are sterilized and sterilized before the use of greenhouses. The roof is covered with a film, and then the lime powder is used to spread the corners of the shed, the shed walls, and the sheds on the ground. Water can also be used to soak the ground, and the ground is sprayed for 2 days. 1 dichlorvos solution, application amount 1-1.5g/m2. In the first 5-7 days before cultivation, it is heavy smoked once with sulfur. When the smoke is smoked, a small resistance can be dug about every 5 meters along the northern wall of the shed, about 250 g of sulfur per pit, digging 5-6. Pit / 30 meters, lit disinfection, closed 2-3 days, the smell gradually disappears to use.

4. The conventional method of doing hoeing and cutting is to prepare soil-covering materials separately, and disinfect the sides while spraying them, and then seal the materials and smoke them. This method has a large amount of production work. If the soil is overturned and the disinfection is not thorough, it will easily lead to pests and diseases. Master Niu will reform and innovate this process. The specific approach is: The ground that will be prepared for the rake is watered 2-3 days before the rake. The specific situation depends on the weather and the degree of soil moisture to determine the amount of water. When the soil is picked up and the hands are in contact, the cultivation can begin. Specific operation: Shun the shed wide side to do the rake, 30 centimeters from the shed wall, will spread the first smashed surface soil, abandoned it, dig a good width of 1.0 meters, 0.1 meters deep, the length of the shed 30 centimeters wide The surface of the work surface is then sprinkled with lime powder in an amount of 2.5-3.5 kg. Then the bacterium bag was peeled off and placed at a distance of about 2 cm on the surface. About 100 cultivating sticks were placed in each pod, and the insecticide was sprayed after one mile. Total dose: Put approximately 20kg of water, 50ml of formaldehyde, 50g of potassium permanganate, and 1 bag of clotriphene in the back sprayer. Spray it evenly like a horse. Dig for the second hoe and smash the second smashed soil. Scoop up and cover it on the first surface. When you pay attention to the buried bacteria, do not leave gaps between the sclerotin bars. In this way, while digging, while shooting soil, while turning over the first squeezing spray liquid, covering the soil thickness of about 3 cm, and finally spray again on the cover surface of the drug, the amount of drug sprayed more than the material surface can be more, After spraying, the black plastic film is covered, and the edge film is fully pressed with soil to complete all work. This is repeated until the shed is finished, placed, sprayed, covered with soil, sprayed, and covered. Generally 200 square meters of greenhouses do 22, two times spray 5-6 barrels. After the operation, the thermometer is inserted in the material and the temperature of the material is monitored not to exceed 25° C. After about 20 days of cultivation, the white mycelium is displayed on the soil surface, and the mycelium is formed in the soil layer. When the primordium is formed, the groove is watered and wetted. The degree of penetration of the soil is a measure of the degree to which water cannot penetrate into the material. At this time, the film can be removed to increase the humidity in the space and enter a large number of buds and fruit body growth management stages.

5. Watering mushrooming management In order to maintain the humidity in the greenhouse, a small amount of water can be added to the furrow. When a large number of primordia appear, a large water can be poured into the operation ditch, and the subsurface layer of the infiltration material layer can grow to the fruiting body. If the air humidity in the shed is lower than 80%, water can be sprayed into the space. Hang wet curtains on the walls. Do not spray water directly on the mushroom body. Pay attention to open hole ventilation. If the humidity is too high, tilt the shed film to increase ventilation. The straw curtain does not need to be lifted to shading to improve the whiteness of the bacteria. The temperature control during the growth of the fruiting body is the most suitable at 15-20°C, and it can be appropriately increased to 12-25°C. The high temperature is not sustainable for a long time to prevent disease and damage. umbrella.

After the harvest, clean up the material surface, make up soil, etc. When the cleaning is completed, it is just the 3rd and 4th days after the harvest. At this time, the water is again irrigated to the operation ditch so that ground irrigation and less irrigation will be performed, and the material surface will remain moist. Not enough water can be sprayed on the material surface, and then after about 10 days, turn the mushroom into the original base, and then water again, continue mushrooming management. Continuous mushroom 3-4 tide, the end of its biological efficiency up to 100%.

This method of cultivation of the cattle master, that is, the use of waste, reduced costs and increased production efficiency, but also simplified the production process, greatly reducing the labor intensity, but also to achieve the purpose of effective control of pests and diseases. Its watering mushroom management, which is mainly based on water-filling method, prevents the water surface phenomenon of the fruit body and effectively controls the occurrence of bacterial diseases on the mushroom surface. At the same time, the humidity in the management shed is not too large and can be avoided occasionally. Unexpected disease caused by high temperature and humidity. In addition, if eggs are found in the feed and there is insufficient nutrition in the later period, liquid medicine and nutrition can be added at the same time when watering.
