On cloudy days, lack of light, the relative humidity in the mushroom shed is large, and in the case of poor ventilation, Pleurotus ostreatus is very prone to two complications of soft rot and bacterial scab.
Soft rot is a fungal disease. Its pathogen is dendrococcal fungi. It belongs to the class of semi-known fungi, clumps, and clumps. Its conidia parasitize the host of Pleurotus ostreatus, and its color mycelium appears and spreads quickly, showing a reddish water. Pleurotus ostreatus becomes brown after the entity becomes infected, and finally rots. Hand rubbed with a lot of yellow-brown water mucus, stench. The incidence of the disease is fast, and the epidemic is widespread. If it is not controlled in time, it can cause devastating disasters.
Bacterial spot disease is a kind of bacterial disease. Its pathogen is Tobrabrinella pseudomonas bacillus, which is mainly harmful to Pleurotus ostreatus. The disease is only restricted to bacteria, and it is easy to occur when there is condensation on the surface of bacteria. After infection, Pleurotus ostreatus had a dark brown blister spot. After the spot was dry, the cap of the mushroom was split and irregular fruiting bodies formed. The disease directly affects the yield and quality of Pleurotus ostreatus and reduces the income of Mushroom farmers.
So how can we prevent this kind of complication? According to our practical experience, we specifically introduce the following comprehensive prevention and treatment methods to Mushok.
1. Breeding disease-resistant varieties, cultivating healthy mycelium, improving the disease resistance of oyster mushrooms, white growth of mycelia, fruiting body with strong disease resistance, and high yield.
2. Increase ventilation and clean the air environment.
3. Use groin water to maintain the relative humidity of the mushroom shed at 65%.
4. Mushroom disinfection. Baiyou powder is sprinkled on the shed walls and sheds. It is economical and has good disinfection and sterilization effects.
5. Drug treatment formula (1) 2.5 million units of streptomycin for agricultural use 50% clotrimazole, 10 g green wind 9550 ml, water 14 kg (2) 2.5 million units of agricultural streptomycin, green wind 9550 ml, Green Fenwei No. 1 17g, water 14kg
Fang Yi: Streptomycin is a broad-spectrum fungicide that kills a variety of bacteria. Ketrimyl has a very good inhibition and killing effect on fungi. The two drugs are used together, and the functions are combined to increase the inhibition and kill the bacteria. Green Wind 95 regulates metabolism and promotes growth. Green Fenway No. 1 is a nutritional supplement. Various drugs are blended according to the above, which not only enhances the resistance of Pleurotus ostreatus, but also kills parasitic bacteria and fungi, and achieves the effect of removing the drug from the disease. Method: One of the above formulas can be used to prepare mixed liquids, fruiting bodies, and sprays of bacteria, once a day, so that it is appropriate to use fruit liquids without dropping liquids. It usually works twice and he recovers three times. Do not spray water on the fruiting body during spraying.
Orthopedic external fixation system
The screw orthopedic is inserted into the bone near the fracture, and the fracture is fixed with an external fixator assembled by a chuck and a nail rod.
Indications
open fracture, nonunion, closed fracture with extensive soft tissue injury, fracture with multiple trauma, osteotomy and correction.
The use of orthopaedic external fixators is currently a superior fracture fixation technique, filling the gap between cast and internal fixation. At the same time, orthopedic external fixator has the characteristics of simple fixation method, stable, reliable and effective, and does not limit the joint movement, can be early ambulation advantages. It can reduce the time for the operator and is more friendly to the user. The external fixator was used together with the bone traction needle. In terms of the classification of orthopedic external fixators, it is mainly divided into four types: orthofix type external fixation, ilizarov type external fixation, ao synthes type external fixation,combined external fixator and common external fixators.
The external fixators in orthopaedics was used for reduction (shortening and overlapping displacement were corrected first, then lateral and angular displacement were corrected, and finally rotational and separation displacement were corrected; If closed reduction is difficult, open reduction can be considered, but the separation of soft tissue and peeling of periosteum should be minimized.
The selection of the insertion site.According to the anatomical characteristics of the soft tissue at the insertion plane, the important nerves, vessels and tendons should be avoided; The ideal entry point is the part of the bone close to the subcutaneous, in a word, generally choose the skin and bone between the muscle soft tissue is the weakest point into the needle. The installation shall facilitate observation and control of soft tissue damage, and permit any surgery that may be required, such as repair and reconstruction, dressing change, skin grafting, or bone grafting." According to the location of the bone, different diameters of the threaded needle were selected. Removal was performed after completion of late treatment.
