Edible fungus production process
First, the cultivation time
The seasonal production of edible fungi is very strong, which is related to the success or failure of production and the input-output ratio. In particular, the time-consuming nature of large-scale production of mushrooms is very important. Once the time is not properly planned, it will lead to great losses caused by the failure, and will also lead to the time difference between the product launch and the market, that is, the effectiveness of cultivation success is also very meager. China's geographical location is very different from the climate, and there are obvious differences in the cultivation time. According to observations, the best time for production in the Chaoyang area is March-April, which is not conducive to the growth of S. edodes at too early or too late.
Nearly half a million bags are produced this spring by our agency. It starts in mid-March and ends in mid-April.
Second, culture material formula
Shrimp mushroom cultivation is very strict on the ratio of culture materials, and the formula meets the nutrients needed for the mycelia of the mushroom. The mycelium can grow vigorously, have strong stress resistance, high success rate, and high yield and high quality. The.
According to the water quality of our office and the texture of raw materials, we used a ratio of carbon to nitrogen ratio of 5:1; PH value of 7.5-8.5, water content of 50-55%; that is: 100 kg of sawdust, 20 pounds of skin , Gypsum powder 2 kg, 1 kg white ash, dry, wet material mix two times, mix evenly after bagging.
Third, sterilization
Sterilization is an important link in the production of edible fungi. Immediately after bagging, it is sterilized. According to the size of the boiler, the number of steaming bags is determined. Generally, 5000-10000 bags per pot are sterilized, and 8-10 hours when sterilization reaches 100°C. Can pan, cooling, ready to receive bacteria.
Fourth, access to bacteria
When the temperature of the bag is below 25°C, the bacteria can be inoculated, and the bacteria shed must be disinfected 4-6 hours in advance. The four-point method was used to cover the mulching culture.
Fifth, bacterial bag cultivation
After inoculating the bacteria, the temperature should be observed frequently. When the temperature rises to 20-24°C, the membrane should be immediately removed from the membrane and the original nine-layer spade be turned into a five-layer spatula and the cover membrane removed. Ventilation culture to bag full.
Six, color management
Whether or not the color change is sufficient is the morphological performance of the mushroom bacterium bag mature. If the poor management is not sufficient, the yield is low, the quality of the mushroom is poor, and the change of the bag from white to light yellow is a physiological mature form. No need to specifically promote cooked. In the meantime, you need to change 3-4 times.
VII. Safer Summer
Mushroom chloroplasts can grow at 5°C, grow best at 18-22°C, stop growing at 30°C, and die at 33°C for three hours. Therefore, we must pay great attention to the observation and management of temperature in the production of slider mushrooms. When sorghum temperature rises to 28°C, it must be turned and cooled in time. Before the high temperature in summer comes, we must make preparations for safe summers; we should put a shady net in advance and have complete water and electricity. When the temperature of the greenhouse reaches 30°C, use sprinkler water on the shed and sprinkle water on the ground to reduce the temperature. Ensure that the greenhouse temperature does not exceed 30 °C, and the temperature does not exceed 28 °C. Otherwise, the cultivation will fail.
Eight, timely open bag, mushroom
After the beginning of autumn, when the temperature of the shed falls to 24°C, it is possible to build a casket and open the bag. After opening the bag, water it 2-3 times a day, and the space temperature is between 90-95%.
Nine, timely picking and processing
Mushrooms harvesting should be based on the needs of customers, domestic sales customers are not very strict specifications, generally within the household 2*4?, open degree is not more than 10% (half open) can be, exporters are mostly Japan, South Korea , Italy, the United States, and some countries in Western Europe, these sales require high quality, generally 2*2?, 2*0.5?.
X. Benefit
Each metre of greenhouses can produce 20,000 bags, about 2.2 yuan per bag. The average bio-conversion rate per standard bag is about 80%. The output value is about 5 yuan, and the net profit is between 4-5 million yuan.
Slippery mushroom is a relatively stable enrichment project. It is a good project for adjusting the industrial structure of counties, townships, and villages and creating brand industries, leading industries and leading enterprises.
