Variety of herbs suitable for winter sowing

According to its growth habits, some medicinal herbs are grown in winter and have many advantages such as rapid seedling growth, homogeneous growth, strong disaster resistance, and high disease resistance.

1. Balloons. Platycodon is a commonly used medicinal herbs, both for food and medicine, suitable for cultivation in mountainous regions, hills, and plains. The species is planted in winter. After sowing the seeds with soil in a certain proportion, it will be shocked and no need to cover grass. The seed will fully contact with the surface through snow and rain in the winter, and it will begin to expand. In the early spring of the second year, After the grass sprouts, the bellflower can emerge. Advantages: Miao Zhuang, Miao Qi, Miao early.

2. Bupleurum is a commonly used bulk medicine, and the contradiction between supply and demand is outstanding. Because the seeds of Bupleurum contain four tough epidermis, the general temperature of 20 °C or more requires 18 to 25 days to emerge. The low germination rate of Bupleurum seeds for many years has become a bottleneck in the development of Bupleurum. After the winter planting of Bupleurum chinense, its tough outer skin slowly starts to change under the influence of climate at low temperature, and the expanded Bupleurum chinense seeds are particularly easy to germinate under the sunshine of spring. Experience has shown that it is a benign planting method to spread the seeds of Bupleurum seeded in wheat fields. So after the receipt of wheat, Bupleurum began to grow rapidly. The facts show that: the winter effect of Bupleurum is good, the emergence of a consistent, improving the quality of medicinal herbs and other advantages.

3. Atractylodes is a commonly used medicinal herbs, generally the whole growth cycle is 2 years, that is, one-year nursery, one year planted Atractylodes. Atractylodes traditional seeding is in the Ching Ming Festival, at this time bred Atractylodis seedlings have the following problems: short seedlings, poor resistance to disaster, easily lead to plant death; yield is low, Atractylodes seedlings are easy to reduce the number of sick. Winter seedlings can overcome these problems. Due to the cold weather in winter, the soil surface is susceptible to freezing, and the seeds of Atractylodes macrocephala are deep in winter so that the cultivated Atractylodis seedlings have stable roots, fast growth, easy opening, and relatively high yield. Second, the emergence of winter seedlings is early, and they are both strong and strong, so the disaster-resistance performance is better.
