The summer production of Coprinus comatus is an anti-seasonal cultivation. Ordinary cultivation sites in summer even reach 30 °C in May, therefore, it is impossible to produce normal high-quality mushroom products, and the temperature of off-season cultivation must be stable at 15 °C ~ 20 °C, the amount of feed is small, the market should be less, the goods Tight price is the general rule of the market. Routine production can not be carried out, but the market consumption is still the same, so the market has a relatively tight "supply and demand contradiction", resulting in double the value of fresh mushrooms. It is predicted that the wholesale price of Coprinus comatus in this summer will be 6-8 yuan per kilogram, or there may be a rising trend. For some time periods, such as July to August, the probability of exceeding 8 yuan is greater. According to this calculation, the production efficiency will be doubled, which will greatly stimulate the production enthusiasm in some areas.
Strain selection
The selection of strains of Coprinus comatus in summer is mainly based on the wide temperature range, large head size, strong resistance and high biological efficiency. At present, there are mainly “Cc518†that meet the requirements of this category, and “Cc168†can still be used.
The choice of cultivation materials and the scientific nature of the formula will show the final results in terms of the quantity and quality of the mushrooms. In fact, this is also an important technical problem that plagues the majority of mushroom farmers. The experience of many years of research and development practice tells us that it is the best decision to select raw materials on the spot; it is wise to pay attention to the comprehensive and balanced nutrition. In specific production, general crop straw can be used, cottonseed shell, corncob, bean straw, etc. Even if wood chips are used, as long as the raw materials are properly processed and the ratio of raw materials is scientifically designed, there will be ideal cultivation effects.
Cultivation site
Natural caves and similar abandoned military facilities are good places for cultivation, such as the Yimeng mountainous area and coastal mountainous areas in Shandong. There are many such facilities; abandoned air-raid shelters, basements, etc., as long as the ventilation problem is solved, it is also a good cultivation site. The “mush hole†specially built by the mushroom farmers in Zibo, Weifang and Jinan shows the advantages of such facilities. The temperature in the above-mentioned place is constant at around 15 °C all year round, which is very suitable for the mushrooming requirements of the chicken leg mushroom. In the plain area without the above conditions, water temperature air conditioning can be installed at the end of the mushroom shed, and the temperature of the shed can be controlled at about 22 °C, which is also suitable for the growth and development of Coprinus comatus.
Basic formula
1, cottonseed shell 220 kg, wheat bran 20 kg, corn flour 10 kg, urea 0.75 kg, lime powder 5 kg, edible fungus three-dimensional nutritional sperm 120 g.
2, corncob 210 kg, wheat bran 30 kg, corn flour 10 kg, bean cake 3 kg, urea 1 kg, lime powder 10 kg, edible fungus three-dimensional nutritional sperm 120 ~ 240 g.
Adding 2 kg of superphosphate and 2 kg of gypsum powder to each of the above formulas can reduce the temperature of the base material, prevent the room temperature from rising rapidly, and improve the success rate of the bacteria.
Cultivation points
1. Strictly handle the cultivation facilities: use the disease killing or Saibai 09 to sterilize the drug in the facility, adopt the method of carpet spraying without leaving a dead angle, and the old mushroom shed that has already suffered from the disease should be continuously treated twice for high-concentration drug treatment. .
2, strain detoxification treatment: the introduction of detoxification strains or self-detoxification treatment to ensure that the strain does not carry any viruses, germs.
3. Formulation of base nutrient: According to the specific cultivation materials, choose the appropriate formula, so that the nutrients in the base material are rich, comprehensive and balanced, so that the hyphae of Coprinus comatus is in a good nutrient environment and maximize the biomass. To lay a solid material foundation for the mushroom.
4, hyphae fully cooked: hyphae after maturing, is a soft technology, should be moderately controlled according to the situation. The main point is: planting in advance, after the surface hyphae is full, try to lower the temperature and try to prolong the time of the bacteria. On the one hand, make the hyphae develop horizontally in the bag, on the other hand, make the hyphae reach the maximum amount, and at the same time make The hyphae achieve a sufficient post-ripening effect, laying the foundation for fulminant mushrooming.
5. Treatment of overburden material: The treatment of covering soil material is the last material condition to ensure the success of anti-season Coprinus comatus cultivation. It must be strictly sterilized. Generally, it can treat about 2 cubic meters of soil per 50 grams of disease, maximizing the increase. The effect of the chicken leg mushroom.
