China is one of the countries richest in medicinal plant resources, with a long history of discovering, using and cultivating medicinal plants such as ginseng. Medicinal plants are numerous and varied, and the medicinal parts differ from species to species; some are used entirely as medicine, such as motherwort and common selfheal. There are about 270,000 known plant species in the world. China has a vast territory, ranging from the cold temperate zone all the way to the tropics, with complex topography and diverse climates, making it one of the countries with the richest biodiversity in the world.
Characteristics of Medicinal Plants:
We are used to calling medicines used in traditional Chinese medicine collectively "Chinese medicines," while the drugs handed down among the people for prevention and treatment of illness are collectively called herbal medicines. Many herbal medicines are recorded in the "materia medica," hence the name "Chinese herbal medicines." Medicinal plants refer to a class of plants that contain bioactive components and are used to treat or prevent disease or have health-promoting functions. Medicinal plant cultivation science is a discipline that studies the growth and development patterns of medicinal plants and their artificial regulation techniques, in order to improve the quality and yield of medicinal materials.
The Value of Medicinal Plants: [Bonsai Ornamental Value]Walking into the greenhouse, large formed reishi mushrooms come into view, their surfaces still carrying a faint luster. "The prototype of the ruyi scepter is the reishi mushroom, and reishi also releases spore powder, so keeping it indoors has health benefits too." Luo Peijuan told reporters that after reishi bonsai came on the market, they attracted many collectors to come and look and buy.
[Medicinal Effects]Sweet in nature, neutral, non-toxic. Active ingredients: reishi polysaccharides, amino acids, etc. It tonifies the kidney and benefits the liver, tonifies the spleen and moistens the lungs. Modern pharmacology shows that it has antibacterial, anti-tuberculosis, anti-fatigue, anti-aging, blood sugar-lowering and blood pressure-lowering effects, and recent studies show that it also improves the body's immune function, lowers serum bilirubin and alanine aminotransferase levels, keeps liver function running normally, and effectively prevents and treats liver damage.
Cultivation characteristics of medicinal plants: First: strong seasonality of cultivation.For most species, the planting period is only about half a month to one month, while for Chuanxiong (Sichuan lovage) and Huanglian (goldthread) the planting period is only a few days to half a month.
Second: field management requires precision.For example, ginseng, Sanqi (Panax notoginseng) and Huanglian (goldthread) need shade sheds to regulate sunlight, while Rensong (Japanese honeysuckle) and Wuweizi (Schisandra chinensis) need pruning and trimming.
Third: harvesting must be done at the right time.For example, Huanglian (goldthread) needs to grow for 5-6 years before harvest, Caomahuang (Ephedra) harvested after 8-9 months of growth has a high content of active ingredients, and safflower harvested when the corolla changes from yellow to red during flowering has the best quality. In addition, medicinal fungal plants such as silver ear fungus, poria and reishi also require special cultivation methods and operating techniques.
Fourth: annual seedlings are best transplanted in spring.After that, plant once every 1 year. When transplanting, the tree hole should be deep and sufficient base fertilizer should be applied. In the seedling stage, proper shading is needed to prevent sunscald. During the growth process, no pruning or shaping is required. In dry weather, pay attention to watering more.
Conclusion:There are many kinds of medicinal plants, and different plants have different medicinal effects. Currently, the prices of medicinal plants on the market are relatively expensive, but their effects are of course much better than ordinary Chinese medicines and Western medicines. The above is our introduction to medicinal plants, and we hope it can help everyone.

Medicinal plants are numerous and varied, and their medicinal parts differ; some are used entirely as medicine, some partially, and some must be refined before use. What characteristics do they generally have? Today, the editor will introduce the characteristics and cultivation methods of medicinal plants.

China is one of the countries richest in medicinal plant resources, with a long history of discovering, using and cultivating medicinal plants. Ancient Chinese historical records include accounts such as "Fuxi tasted a hundred medicines" and "Shennong tasted a hundred herbs, and in one day encountered seventy poisons." The cultivation of medicinal plants has strict requirements for environmental conditions, and climate and soil are the main environmental conditions affecting the growth and development of medicinal plants. Various medicinal plants have different requirements for light, temperature, water, air and other climatic factors as well as soil conditions.

.....
For example, mint likes plenty of sunlight, and clear weather during the bud and flowering stage can increase its oil content. Betel nut, coca and pepper can only flower and bear fruit in hot, humid areas. Oriental waterplantain and sweet flag require low-lying wetlands to grow. Ephedra, licorice and aloe have strong drought resistance and are mostly distributed in dry areas. Dwarf lilyturf and Ningxia goji like alkaline soil, while magnolia bark and gardenia like acidic soil. Species whose roots and underground stems are used as medicine are suitable for planting in fertile, loose sandy loam or loam, etc.

The cultivation techniques for medicinal plants should pay attention to the following points.
1. Cultivation season: for most species, the planting period is only about half a month to one month, while for Chuanxiong (Sichuan lovage) and Huanglian (goldthread) the planting period is only a few days to half a month.
2. Field management requires precision; for example, ginseng, Sanqi (Panax notoginseng) and Huanglian (goldthread) need shade sheds to regulate sunlight, while Rensong (Japanese honeysuckle) and Wuweizi (Schisandra chinensis) need pruning and trimming.

What about the cultivation methods for medicinal plants? Follow the editor to learn about them. Annual seedlings are best transplanted in spring, and after that plant once every 1 year. When transplanting, the tree hole should be deep and sufficient base fertilizer should be applied. In the seedling stage, proper shading is needed to prevent sunscald. During the growth process, no pruning or shaping is required. In dry weather, pay attention to watering more. For mature trees, after the leaves fall each winter, trenches should be opened for fertilization, so as to promote more branches and leaves and more flowers the following year.
.....
.....
Medicinal plant seedlings like moisture and fertilizer. The spacing between plants and rows for transplanting small seedlings can be decided according to how long the seedlings will remain in the nursery bed; if the stay is long, the spacing can be larger. Before transplanting small seedlings and large seedlings, sufficient base fertilizer should be applied. Horse chestnut is generally best transplanted after the soil thaws and before the seedlings sprout, or after leaf fall in autumn and before the soil freezes. Before transplanting large seedlings, thinning of branches is needed, removing overly dense branches, overlapping branches, interwoven branches, diseased and dead branches from the crown, and cutting back broken branches, with the amount of thinning about one third; when necessary, to reduce evaporation, some leaves need to be removed.

Medicinal plants occupy an important position in medicine, and the protection and development and utilization of their resources will receive further attention. The further application of plant chemotaxonomy methods will help find and expand new resources of medicinal plants. Today's introduction by the editor on the characteristics and cultivation techniques of medicinal plants ends here. Thank you all for reading.
