Pleurotus ostreatus imitation wild high yield and quality cultivation
April 23 05:02:37, 2019
Pleurotus ostreatus, which is produced by adopting the technique of wild cultivation, not only tastes wild and delicious, but also can truly realize high quality and high yield. Even in the early winter seasons of cold winters and low temperatures, the ground temperature can be fully utilized in a relatively closed shed to produce a high-quality, fresh, high-quality oyster mushroom. This method increases production by more than 60% compared to conventional cultivation methods, increases production by more than 40% compared to cultivation methods such as fungal walls, and has a biological conversion rate of 220% or more. First, mycelium culture. Sterilization by high pressure or pressure, conventional inoculation, culture to achieve a physiologically mature mycelium. Fermentation material mycelia obtained by treating raw materials with high temperature and strong alkali may also be used. Specific practice: add 4% quicklime, add lime in the form of ingredients, mix well. Then 1000 kilograms for a heap, stuffy fermentation. When the material temperature reaches above 60°C, maintain it for 24 hours, turn it over, and repeat 2-3 times. When raw materials feel sticky and elastic, brownish brown, no peculiar smell, pH value 7.5, moisture content 65%, spread out and cool down, and the stuffing bacteria (or lumps of bacteria) are cultivated into a pollution-free bag full of bacteria. Regardless of clinker, fermented material, raw material full of bacteria, the raw materials used can be cottonseed husk, corncob or other substitute materials. The bacteria used should be high-quality strains that have been tested and have good overall traits. Second, the shed construction. Choose sheds of high quality land with gardens, yards or sandy loam. The shed was dug 20 meters long, 1.3 meters wide, and 0.22 meters deep. In the middle of the road, there is a sidewalk. When arching, the bamboo with a diameter of 4 cm or more is folded into an arch, then reinforced with a horizontal bamboo, covered with a film and covered with a grasshopper (it can also be a variety of straw woven shade). Third, the bacteria bags put. Take a 30 cm long bag (if it is a long bag) and take off the plastic film. Place the bag at an angle of 75 degrees until it is full. When bag is inspected, it is necessary to carefully check whether the bag is infected with bacteria. If so, use the weapon to remove it to prevent the spread. Fourth, cover soil treatment. The soil-covered material is preferably loam, treated with 1% lime powder in late fall and winter and early spring, and treated with 3% lime powder in late spring, early autumn and summer: Mix the lime powder evenly into the soil, and strive to have no large particles. The treated soil can be covered with a well-laid bag. The top soil thickness of the bag is 1.5 cm, and it is leveled with a broom. Fifth, irrigation requirements. Water can be used to pump groundwater or other clean water sources, flooding from one end of the crucible until the crucible is fully infiltrated, and let the water stay in the crucible for 12 hours (if it is a mushroom bag, it is easy to drift, then it can be pressed after the water penetrates. ). After flooding through this method, part of the earth over the ground may sink. After the water in the raft has penetrated, spread a layer of soil and flatten it, then sprinkle the nutrient water (from 2% urea, 0.2% magnesium sulfate, zinc, trace amounts of granate, high-growth or other auxin, and high-efficiency liquid compound fertilizer. Composition), so that the new Satu wet and not trapped, the skin can be sticky after a little dry. Six, high yield principle. According to the conventional method of producing Pleurotus ostreatus, the main factor constraining the high yield is the loss of water and nutrients after the oyster mushroom is used. The hyphae are easy to be aged, and it is difficult to produce good oyster mushrooms. Using this technology, each mushroom can be fed with nutrient water once, so that the mycelia can maintain nutrients and water, which can extend mycelium life and fruiting period. One week after the irrigation of the soil, the new mycelium connects the whole fungus bag into a whole. During the mushrooming and growing process, the soil continuously supplies nutrients and moisture to the mycelia, so the mushroom body is still hypertrophied and fresh during the second and third seasons. Stronger stamina. As the humidity in the greenhouse is suitable, the shade is good. From the formation of small buds to the harvesting of mature mushrooms, the environment of the long mushroom is like a damp tree-lined place, which overcomes the disadvantages of difficulty in controlling the humidity of the conventional cultivation space and the difficulty of supplying nutrients and moisture to the bacteria bags; On the micro-fertilizer, hormones, auxin can be infiltrated with the irrigation water into the soil, easy to absorb and use the mycelium, so you can get stable and high yield, high quality and efficiency.
What should we do when there is a minor trauma in
one of our limbs or body parts, or before surgery / puncture? First of all, you
should promptly disinfect the wound or skin to ensure a sterile environment, so
that patients are not infected. Sometimes, using a cotton ball or Gauze dipped
in lotion will be more inconvenient, and waste time. Surrounding this theme,
Yingmed provides a series of small packs of disinfectant pad and products with similar
using methods, such as Alcohol Prep Pad, Povidone-iodine prep pad, sting
relieve, Adhesive tape remove pad, Povidone-iodine swabsticks and so on.
At Yingmed, you also find other products for wound
care such as Wound adhesive plaster, Self-adhesive eye pad, Gauze Swab,
Self-adhesive Wound Dressing, Hydrocolloid dressing.
