Yuji mushroom is delicious and has good palatability and is loved by consumers. In recent years, Japan’s demand has doubled and the market has great potential. It has become one of the five largest cultivated mushrooms in Japan. In 1995, our institute introduced high-yield strains from Japan, followed by a systematic study of its biological characteristics and cultivation conditions. It was successfully cultivated in indoor trials and was cultivated in large outdoor areas to obtain higher yields. Its high-yielding cultivation techniques are described below. First, biological characteristics. Hymenoptera is a low-temperature, temperature-varying, solid fungus. The test results show that the mycelium growth requires a higher temperature and the fruiting body requires a lower temperature. The suitable temperature for mycelial growth was 20-25°C, and the suitable temperature for fruit body differentiation and growth was 13-17°C. Hypsizygus marmoreus is a kind of aerobic and hygroscopic fungus. The growth stage of fruiting body needs fresh air, the space humidity requirement is 85-90%, the pH of the culture material is suitable for 6.5-7.5, and the water content is 65-70%. Moderately scattered light facilitates the differentiation and growth of fruit bodies. Second, cultivation techniques 1, cultivation season. Since the oyster mushroom is a low-temperature type mushroom, the mushrooming season is more suitable in late autumn and spring, so it is more appropriate for the southern region to start producing bacterium bags in September, and the outdoor pods in the second december to the middle of March will be better. 2, preparation of culture materials. The formula of the suitable culture material for the growth of oyster mushroom is: broad-leaved wood chips 75%, wheat bran 15%, corn flour 3%, soybean powder 3%, gypsum 2%, lime 1%, sucrose 1%, potassium dihydrogen phosphate 0.2% , Magnesium sulfate 0.1%. Preparation of culture materials: After wood chips, wheat bran, corn flour and soybean powder are weighed in proportion, pour it on the cement field, and dissolve gypsum, lime, sucrose and potassium dihydrogen phosphate, and magnesium sulfate in proper amount of water. Stir in the mixture with the above ingredients, so that the moisture content of the culture medium is 65-70%, and the pH is adjusted to 6.5-7.5. 3, bagging sterilization. A 17 cm 30 cm pressure-resistant plastic bag was used. Each bag was charged with about 400 g, autoclaved (122°C) for 3-4 hours or normal pressure sterilization (100°C) for 8-10 hours. 4, access to bacteria and bacteria. The culture materials were sterilized and pre-cooled to below 25°C to inoculate them. The amount of bacteria should be more, and it is advisable to use about 30 bags per cultivar. Since the germination period coincides with the summer and high temperature seasons, the doubling chambers should be selected in a cool, dry area, with double bags backed up into strips. Each stack should be 7-8 layers high. Turn over 2-3 times. Use exhaust fan for ventilation for a short period of time to reduce the concentration of carbon dioxide, which is beneficial to germs. After 45-55 days in general, the hyphae can fill the bag. When the mycelium reaches a physiological maturity, the mycelium turns from light grey to dark white, the culture material has become a lump, and the hyphae begin to kink. 5, outdoor arch way cultivation. The plots with higher groundwater levels were selected and after weeding and soil preparation, a grass shed was set up. The shed was 2.5 meters wide and divided into 2 poles. The upper part was then covered with a plastic arch shed with a height of 2.2 meters. The shed and the plastic sheds formed a covered shed. Bacteria bags are either faceted or double decked. 6, fruiting period management. When the mycelia of the fungus bag began to appear kink, open the bag of bacteria and inject fresh water into the bag. After 3-4 hours of letting go, pour out the water and then pounce. Cover the bag with a plastic film or wet newspaper to moisturize and rejuvenate the buds. Temperature is controlled at 14-16 °C. After secondary bacterial growth occurs in the bag after 3-4 days, remove the covering, properly ventilate, reduce the concentration of carbon dioxide, increase the transparency, and promote primordial differentiation. When a dense needle bud was formed on the surface of the bacteria bag, the primordium around the bacterium bag was gently scraped off with a wire file, leaving a central primordium of 5-6 cm in diameter. Ensure that these fruiting bodies are well-fed and promote good growth (generally 15-20 flowering mushrooms per bag). The temperature should be kept below 18°C ​​during this period, and over 20°C will affect fruit body growth. The space humidity should be kept at 85-90%. The method of ground pouring and space spraying should be adopted to increase the space humidity. Be careful not to spray water directly on the buds, otherwise it is easy to cause bad buds. 7, timely harvest to ensure quality. It takes 15-18 days from the formation of needle-shaped fruit bodies to harvesting. The oyster mushroom is clustered, and each pod can grow 15-20 pods. When the largest one has 3.5 cm of veil, it should be holstered. The mushrooms were all harvested, and they were collected in clusters after the harvest, and the flowers were collected again. Use a knife to cut off the mushroom's feet and debris. Leave the stalk length 5 cm long and then grading and packing according to the size of the cap. 8, after the harvest management. After the first tide mushroom is harvested, the residual mycorrhiza and dead mushroom should be promptly removed, and the surface 1 cm culture material should be dug. After the water is sprayed, the bacterial bag is covered with a plastic film, so that the mycelium can fully recover the germ, and then transferred. The second tide mushroom management, if necessary, can increase nitrogen, phosphorus, potassium mixed nutrient solution to increase nutrition. Generally can harvest three tide mushrooms, biological efficiency of 40-80%. III. Pest Control 1. Green mold: When the oyster mushroom bursts in the field, buds will develop green mold on the surface of the bacterium. When it is found, 600 times of carbendazim solution should be excavated and used on the portable sprayer to prevent further expansion. . 2, wild pheasant: In the field when planting pods, fleas occur more, the worm in the daytime to hide in the soil, at night out to take the mushroom body, resulting in lack of engraving, affecting the quality. Control methods: Using 3% Mida granules, scattered in the surface of the soil to trap and kill the insect. 3. Mushroom fly: When the mushroom body is harvested, it will attract Mushrooms adults into the mushroom shed. The adult lays eggs on the mushroom body, and forms a pest-infested mushroom body that affects the yield after hatching. Control methods: Use 25% kung permethrin 1000 times to spray around the mushroom shed, kill Mushroom fly adults, reduce the amount of insects, and control hazards.
It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
[Functions of medical eye masks]
1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.
4. The breathability must be good, generally there are vents
