Brazilian mushroom cultivation techniques
Brazilian mushrooms, also known as Agaricus blazei, are nutritious and delicious. They are popular with consumers because they are similar to the precious Matsutake flavor. They are a very popular mushroom strain in foreign countries. In addition to its unique flavor, it also has a high medicinal value. Its polysaccharides have peculiar effects on tumors and can improve the human immune function. In the current cultivated edible fungi, cultivation quantity ranks first, and the price is expensive. Pleurotus 5 to 10 times, the outlook is very promising. According to the requirements of readers, some artificial cultivation techniques are briefly introduced.
First, the production season choice: spring and autumn can be produced, spring broadcast should choose to be carried out in early March to mid-May, autumn broadcast should choose to be carried out in September to mid-November.
Second, culture material formula
1. Straw (375 kg) + rice bran (10 kg) + chicken manure (15 kg) + lime (8 kg) + ammonium sulfate (10 kg) + superphosphate (5 kg).
2. Corn stalks (360 kg) + cottonseed hulls (360 kg) + wheat straw (115 kg) + dry chicken manure (150 kg) + calcium carbonate (10 kg) + ammonium sulfate (5 kg).
3. Thatch (750 kg) + cottonseed husk (130 kg) + dry chicken manure (100 kg) + compound fertilizer (5 kg) + quicklime (15 kg).
Third, the preparation of culture materials
Straw straw and other raw materials are first soaked in wet for 2 to 3 hours. When the heap is built, a layer of straw is laid below, a layer of lime powder is sprinkled, and poultry dung is scattered in the inner layer while other materials are placed on the droppings. , Stacked in layers, piled into a width of 80cm to 90cm, a width of 120cm to 150cm, a height of about 100cm, and a moisture content of about 65%. After the stack is built, pay attention to the measurement temperature, and maintain the temperature when the temperature rises above 65°C. ~7 days, the first turn of the heap, if the water shortage should be timely replenishment, after the interval of 5,4,3,2 days after another turn. The fermented material turns brown and has no smell and no sour taste.
Fourth, sowing
Points sowing and sowing. Cave sowing: Every 20cm to 25cm on the culture material, dig a 10cm deep inoculation hole, broadcast the strains, covered with a layer of culture material about 1cm thick. Spreading method: The bacteria seeds are crushed and evenly sprinkled on the surface of the material. The material surface is lightly compacted by hand or with a wood board, and about 3 to 4 bottles per square meter are needed. After planting, pay attention to ventilation in the shed. Observe the growth of mycelium.
V. Mushroom management
Under normal circumstances, the Brazilian mushroom needs about 20 to 25 days from sowing to mushrooming. It takes about 3 to 5 days for each tidal mushroom and about 20 days for two tidal mushrooms. It can harvest 3 to 4 tidal mushrooms each time during the growing season. The learning efficiency can reach 40%. The management of the fruiting period is mainly based on thermoregulation and humidity adjustment. When the temperature is low, you can cover the film insulation, shorten the ventilation time and frequency, so that the temperature increases; if the temperature exceeds 28 °C, you can increase the ventilation time and the number of times, so that the temperature drops.
After 25 days of sowing, the hyphae begin to kink, and at this time, water spray can be started, generally spraying 2 to 3 times. When water is sprayed, pay attention to spray heavy water and ensure no leakage of material. When the fruit body grain is large, do not spray heavy water; after spraying heavy water, it should be ventilated for 1 to 2 hours to improve the ventilation condition. Do not spray heavy water at high temperatures. Water spray is usually performed in the morning or evening.
6. Harvesting
When harvested mushroom body cap has not yet opened the umbrella, the surface is light brown, there are fibrous scales, the membrane has not yet ruptured, cap diameter 4cm ~ 10cm, handle length 6cm ~ 14cm for the harvest period. After harvesting a tidal mushroom, replenish soil and remove weeds at the unbalanced part of the mushroom bed; increase ventilation, stop spraying for 1 to 2 days, then spray water, cover the film, and prepare for the next mushrooming. .
