In winter, the temperature is low and the water evaporates slowly. Most of the medicinal plants have entered a dormant state, which is the golden season for the cultivation of some herbs. Planting herbs in winter have many advantages such as quick emergence, growth, resistance to disasters, and good disease prevention. The following three Chinese herbal medicines are suitable for winter planting. 1. Bupleurum. Bupleurum is a commonly used bulk medicinal material. It is mainly wild in history, and the contradiction between supply and demand is prominent. After the 1980s, the family of Bupleurum was fully promoted, and the traditional planting was mainly in spring. Since Bupleurum seeds contain 4 layers of tough epidermis, it takes 18 to 25 days for the seedlings to be emerged at temperatures above 20 °C. The low germination rate of Bupleurum seeds has become the bottleneck for the development of Bupleurum. Experience has shown that planting Bupleurum in winter can solve the problem of low germination rate of Bupleurum. Because Bupleurum is planted in winter, its tough skin gradually changes under the influence of climate at low temperatures, and the expanded Bupleurum seeds are particularly prone to germination under the spring sun. 2. Campanulaceae. Platycodon grandiflorum is commonly used in large-scale medicinal herbs, both medicine and food, distributed in mountainous areas, hills and plains throughout the country. The traditional planting of this product is to use seed to breed in spring and summer. The sand is evenly spread on the soil in the whole land, and the grass can be shaken after the flat. The disadvantage is that the drought is not easy to emerge, and the weeds affect the growth of the platycodon seedlings. In the winter planting, the seeds are mixed with soil in a certain proportion, and then the earthquake is slightly suppressed. It is not necessary to cover the grass. The seeds are moisturized through the whole winter snow and rain, fully contact with the surface and begin to expand. In the early spring of the second year, the grass buds After the hair, the platycodon can be emerged. The advantages are Miao Zhuang, Miao Qi, and Miao Zao. 3. Atractylodes. Atractylodes is a commonly used bulk medicinal material. Generally, the whole growth cycle is two years, that is, one year of seedling cultivation, and a year of commercial atractylodes. Atractylodes traditional seedlings are in the Ching Ming Festival, when the climate is milder, generally 7 to 10 days after sowing can be emerged, and such albino seedlings have short seedlings, poor tolerance, and easily cause plant death (because of spring viruses, germs) More, the resistance of Atractylodes sinensis is poor, the yield is low, and the Atractylodes macrocephala is very easy to reduce production. In winter, the seedlings can overcome the above problems. Because the winter climate is cold, the soil surface is easy to be frozen, and the winter seeding atractylodes seeds are deep. The cultivated Atractylodes macrocephala seedlings are stable, grow fast, easy to open, and have relatively high yield. Secondly, the winter seedlings emerged early, and they were both strong and strong, so the disaster resistance was better. Disclaimer: Some articles on this website are transferred from the Internet.

Spinal fixation system consists of posterior spinal fixation system,minimally invasive spinal system,posterior cervical fixation system,anterior cervical plate system,laminar shapping plate system and interbody fusion cage system.
Cervical and lumbar segmental implants are the most common types of spinal internal fixation, which can be roughly divided into anterior and posterior internal fixation according to their fixed positions and surgical approaches.
The anterior cervical vertebra is mostly fixed with locking plates and fixed screws,what are mostly made of titanium alloy materials; The posterior approach was fixed using the pedicle screw and rod system.
In some cases of spinal vertebrae bone defect, it is also necessary to implant titanium cage or PEEK cages to promote bone fusion of adjacent vertebrae. The titanium mesh cage refers to a cage shaped container made of titanium alloy material, which is loaded with autologous or allogeneic bone and placed in the spinal vertebrae bone defect, which not only serves as a strength support but also plays a role in bone fusion.
