The inventive technique process of grainy calcium material for preventing and treating peanut blight primarily includes: adopting the shell powder and weathered coal as raw materials, machining into peanut blight prevention material through agglomeration granulation. The invention has innovative and reasonable design, which not only has simple process, easy implementing, but also has low cost of raw materials, product application convenience, remarkable peanut blight prevention effect, and capability of promoting high-efficient production pf peanut. In particular, the invention applies coastal oyster shell wastes for machining calcium materials for preventing and treating peanut blight, which not only reduces environmental pollution, but also promotes recycling of resources, has very significant economic, social and ecological benefits and greater promotional value.

The invention relates to the field of medical instruments, in particular to a positioning and binding device for orthopedic reduction fixation, which comprises a bottom shell, positioning grooves are formed in the front side and the rear side of the upper end of the bottom shell, slave insertion holes are formed in the inner walls of the two sides of the front portion and the rear portion of the bottom shell, and first combination rings are fixedly connected to the outer walls of the two sides of the bottom shell. A carrying block is fixedly connected to the inner wall of the middle of the lower end of the bottom shell, and a covering mechanism is installed at the upper end of the bottom shell. The two locking mechanisms are arranged in the bottom shell, in the using process, rotating discs of the two locking mechanisms are twisted, then locking ropes are continuously twisted, the clamping plates are tightly bound to the limbs of a patient through the two locking ropes, the rotating discs are clamped in clamping grooves in the top disc in the fixing process, the locking ropes are kept in a locked state, and therefore the patient can be fixed conveniently. And in the later period of loosening, only the rotating plate needs to be rotated out of the clamping groove, the rotating disc is rotated reversely, and the process is convenient.
