There is a direct relationship between the amount of water in the golden needle mushroom and the level of yield and quality. Therefore, changing the conventional management methods during the fruiting period and strengthening water and fertilizer management in a timely manner can achieve ideal results. The cultivation and management of Flammulina velutipeti and Pleurotus ostreatus are different, because the fruiting period should not be directly sprayed into the fruit body and the material, so after harvesting mushrooms, the culture material is seriously deficient in water, and it will be difficult to produce mushrooms. Abandon management, resulting in low output. Therefore, spa is an important measure.
First, keep water. After the mycelium is sent to the bottom of the bag, the bag is immediately opened and the old fungus is removed, and the newspaper or plastic film is covered to moisturize the buds. Covered with newspapers, the water spray should be applied a small number of times, 3-4 times a day to keep the newspapers moist. Covered with plastic film, water can be sprayed on the ground and space to keep the air humidity about 90%. During this period, the windows were ventilated once a day, and the room temperature was controlled at 10-14°C. After 5-7 days, mushroom buds occurred in large numbers.
Second, spray water. When the mushroom body grows to 3-4 cm, after entering the extension period, spray water 4-5 times a day. The amount of water spray increases with the growth of the mushroom, and the air humidity is controlled to be about 90% (that is, appropriate water beads attached to the wall of the fruit body base), and the rapid growth of the fruit body is promoted. At the same time, appropriate ventilation, alternating wet and dry to inhibit the increase in mushroom cap and mushroom elongation. The amount of water sprayed at this stage should be determined according to the weather. Spray more on sunny days and spray less on rainy days to prevent root rot, brown spot, and excessive water in the mushrooms to reduce the quality due to excessive water use. Do not spray water on the mushroom lid, found that newspapers should be replaced in a timely manner. Newspapers should immediately drain water to prevent mushroom body contact with water droplets to produce black spots, affecting the appearance of goods.
Third, replenishment. After the mushroom bag was harvested in the first tidal mushroom, the water content decreased by 20% to 30%, and the tidal mushroom decreased by 30% to 50% after harvest. Therefore, after the first and second tidal mushrooms are harvested, they must be filled with water and moistened immediately. The mushroom planted in the greenhouse is generally replenished after harvesting a mushroom. Its approach is: direct injection of nutrient water into the bag, the amount of water injection is based on the amount of mushrooms, that is, how much water will be filled up after the completion of the mushroom, and the water in the bag should not be allowed to accumulate. The formula of nutrient water can refer to the ratio of the nutrition solution of oyster mushroom.
Black and White Ultrasound Scanner
"Black and White Ultrasound Scanner" is to emit ultrasonic waves, so that the ultrasonic waves encounter barriers to generate echoes, use the computer to collect these echoes, convert them into corresponding images and display them on the screen, and the images measured by the ultrasonic probe are black and white, so it is called " Black and White Ultrasound Scanner" is also the earliest diagnostic technology adopted by b-ultrasound.
"Black and White Ultrasound Scanner" has the advantages of non-invasive, high sensitivity, low cost and convenient operation
