What are the growing conditions for ginseng? A detailed explanation of the latest cultivation requirements
Ginseng is a traditional Chinese medicinal herb in our country, known as the king of a hundred herbs, and its efficacy and effects are world-famous, with large quantities exported abroad every year. With the scarcity of wild resources and the development of artificial cultivation, after many years of cultivation, the current ginseng planting area in our country still cannot meet market demand. The main reason for this is the requirements ginseng has for its growing environment, so what conditions are needed to grow ginseng? Let's learn about it together.
1. Growing environment
Ginseng likes a cool and shady environment. When planting, choose an understory environment of broadleaf forest or mixed broadleaf-conifer forest, preferably a forest dominated by oak and linden trees, so that it can meet its needs for light, temperature and moisture.
2. Soil
Ginseng has strict requirements for soil. The soil organic matter content must reach more than 3%, the pH value must be between 6-6.5, and in addition the concentration of pentachloronitrobenzene in the soil must not exceed 0.3 mg per kg of soil. It is suitable for planting in well-drained, loose and fertile deep forest soil with a deep humus layer, or mountain podzolic brown forest soil. In addition, it is neither drought-tolerant nor waterlogging-tolerant, so soil moisture control must be extremely strict, with 70%-80% being best. Therefore, doing a good job of drainage and irrigation when planting is a key point in growing ginseng.
3. Light
Ginseng is a shade plant and is quite strict about light. If the light is too strong, the plant will be short with thick and yellow leaves; if the light is too weak, the plant will be tall and spindly with thin and dark green leaves, and its growth will be abnormal or deformed. Therefore, when planting, shading must be reasonable: it is necessary both to avoid strong light exposure and to reasonably use scattered light and refracted light so that it grows normally. Generally, the suitable light intensity for ginseng growth changes with latitude and temperature. The higher the latitude and the lower the temperature, the stronger the light it needs, and vice versa.
4. Fertilization
Ginseng is a fertilizer-loving plant. When planting, humus-rich soil is generally used, which can provide the nutrients needed for its growth, but fertilization is generally carried out during planting to make it grow faster. It likes organic fertilizer and inorganic fertilizer, but it is afraid of fertilizer that is not decomposed or not fully decomposed, as this will cause the soil to lose water and burn its roots. Therefore, when fertilizing, fully decomposed organic fertilizer or inorganic fertilizer must be applied.
