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, disaster resistance and 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 is slowly changing under the influence of climate at low temperatures. The expanded Bupleurum seeds are particularly prone to germination under spring sunlight.
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 according to a certain proportion, and 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 atractylation. Atractylodes traditional seedlings are in the Ching Ming Festival, when the climate is mild, 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 the yield is relatively high. Secondly, the winter seedlings emerged early, and they were both strong and strong, so the disaster resistance was better.
