Ginseng potted video tutorial

Ginseng is a cool, moist and shade-tolerant medicinal plant, which is not only afraid of stagnant water, but also resistant to drought, and avoids direct sunlight, and has strict requirements on growth environment conditions.

(1) Soil: Ginseng requires sandy soil with rich humus, deep soil layer, loose texture, strong water permeability and good drainage. Forest humus soil is the best, neutral or slightly acidic soil is better, and alkaline soil is not suitable for planting.

(2) Moisture: Ginseng has strict requirements on moisture, and prefers water to waterlogging. Too much water, when the soil humidity exceeds 60%, will cause insufficient air in the soil, affect the root respiration of ginseng, and easily infect diseases and rot roots. If the water content is too small, when the soil water content is lower than 30%, it will cause the water diffusion of ginseng roots, make ginseng fibrous roots dry up, and lead to a decline in yield. Ginseng needs suitable soil moisture during its growing period, which should be kept at about 40% in spring, 45%-50% in summer, 40%-50% in autumn and 40%-50% all year round.

(3) Illumination: Ginseng is a shade-loving plant, which likes to scatter weak light and is afraid of direct sunlight. The light is too strong, the plants are short and the leaves are thick and yellow. The light is too weak, the plants are thin and tall, the leaves are thin and dark green, and the growth is abnormal. Therefore, in ginseng cultivation, it is necessary to shade, adjust the light transmittance, avoid direct glare, and use scattered light and refracted light.

(4) Temperature: Ginseng is afraid of high temperature and cold. During the growth and development of ginseng, the average temperature is 15-20℃. When the temperature is higher than 30℃ or lower than 10℃, ginseng is in a dormant state. It is also safe to overwinter in the cold of -40℃ in winter. Ginseng regenerated buds can germinate and grow above the ground temperature 10℃ in spring, but they are most afraid of "slow sun freezing" in early spring (that is, the temperature rises and falls suddenly, and the surface freezes and freezes), which is easy to cause freezing injury and root skin damage ("broken belly"). After sowing, the seedling temperature should be above 10℃, the annual temperature of 1-2 years should be above 12℃, the optimum temperature for the growing period is 20-25℃, and the leaves will scorch under the scorching sun above 36℃. Below -6℃, the stem will lose its growth function.

(5) Fertilizer: Ginseng likes fertilizer, but it is afraid that fertilizer will not decompose. I like organic fertilizer and inorganic fertilizer, but I'm afraid that the application of immature manure will lead to water shortage in the soil after fertilization, which will lead to ginseng burning roots.
