Wave cultivation of Coprinus comatus can increase yield
The so-called wave cultivation mode is to design the culture material on the bed surface into a kind of undulating wave crests and troughs, which resemble the waves on the surface of the water. The most important advantages of this cultivation mode are: First, it increases the surface area of ​​the bed surface for fruiting. Compared with the flat cultivation bed surface, the fruiting area is increased by more than 50%. The second is to effectively control the microclimate environment on the bed surface and the material. It is superior to the flat cultivation method in terms of ventilation and oxygen supply, removal of harmful gases in the material, and control of the temperature of the material. Third, without increasing any investment, the yield per unit area of ​​cultivation can be increased by 30% to 40%, the biotransformation rate of raw materials will be maximized, and economic benefits will increase significantly.
Operation and implementation methods: The production procedures such as ingredients, fermentation, arrangement and disinfection of cultivation sites in the early stage of production, and various management tasks in the later stage of cultivation are the same as conventional cultivation methods. The difference is: First, the width of the box surface is designed to be 120 cm, which is beneficial to improve the utilization rate of ordinary agricultural film. The second is to use layered seeding, that is, 2 layers of material and 2 layers of seeding to speed up the germination speed. Third, when spreading and planting, spread three strips of 30 cm wide on the surface of the box longitudinally at equal distances, with a thickness of 10 cm, leaving two 15 cm wide gaps in the middle. After the material surface is slightly leveled, sown 1/3 of the strain used, and then spread a layer of 15 cm thick material on the material surface, and at the same time spread the material 3 cm thick at the reserved space, and then arrange the material surface In a semicircular shape (turtle-back shape), it forms wave crests and troughs, the crest height is 22 cm, and the trough bottom is 15 cm wide. Finally, evenly spread the remaining 2/3 strains over the material surface, gently pat it flat with a wooden board, cover with a film and straw curtain, keep warm and moisturize, and manage the bacteria. After about 15 to 20 days, when the hyphae in the material are half or 2/3 of the length of the material, the artificially improved soil shall be covered in time. When covering the soil, the thickness of the covering of the wave crests and troughs should be up to 5 cm. After 15 to 18 days after covering the soil, a large number of mushrooms can be grown at the wave crests and troughs. Tests have proved that when the thickness of the soil covered with Coprinus comatus is about 5 cm, the individual mushrooms that grow out are fat, stubby, late to open the umbrella, high yield, good quality, high price and sell well.

Lower Limb Locking plate is a kind of implant fracture orthopedics with locking thread holes.
The lower limb locking plate allows the bone to bind to the plate more firmly, so that the reduced limb is more stable. Locking plates were first used in spine and maxillofacial surgery 20 years ago to stabilize fractures while reducing extensive dissection and damage to soft tissues. When the threaded hole in the locking plate is screwed in by a screw with a threaded head, the plate becomes an Angle fixing device. It can have both locking and non-locking holes for different screws to be screwed in. Any plate that can be screwed into an Angle fixed (stable) screw or bolt is essentially a locking plate.
Locking plate system does not rely on bone friction to achieve connection, but completely depends on the interlocking structure of the plate itself. A certain gap between the plate and the bone surface can be left, which can eliminate the adverse effect of heavy pressure contact between the plate and bone, and greatly improve the blood supply and the growth and recovery of the periosteum. The main biomechanical difference from conventional plates is that the latter relies on friction at the bone-plate interface to accomplish plate compression on bone. Stability is maintained by an angularly stable interface between the screw and the plate. Because the locking internal fixator has a stable integrity, the pull-out force of the locking screw is much higher than that of the ordinary screw. It is difficult for a single screw to be pulled out or broken unless all the surrounding screws are pulled out or broken.
