What are the precautions for growing American ginseng?

American ginseng is a type of ginseng introduced to China from Europe and America, and it is also called huaginseng. It has effects such as tonifying qi and nourishing yin, clearing heat and promoting fluid production, as well as eliminating fatigue, enhancing memory and relieving insomnia. It is a relatively expensive medicinal herb. In China, the main producing areas of American ginseng are Shaanxi, Jilin, Heilongjiang and other places. So how is American ginseng grown? What should be noted when planting it? Below we will learn together about the precautions for growing American ginseng.

1. Soil

For growing American ginseng, the soil should generally be relatively fertile farmland, and before planting, the pH of the soil should be tested. Next, the soil should contain a large amount of humus and be relatively loose sandy soil or loam. At the same time, the previous crop in the farmland cannot be crops such as radish, cabbage, melons, fruits and eggplants, so this must be noted when choosing a planting site. Finally, the planting site should also be chosen in a wind-sheltered area to avoid affecting the normal growth of American ginseng.

2. Germination

When growing American ginseng, be sure to treat and germinate the seeds. Generally, carbendazim can be used for disinfection and sterilization. Soak for about half an hour, then remove the seeds, rinse off the remaining chemical in clean water, and finally place them in an environment with a temperature of 18 to 20 degrees for germination. Alternatively, soak them in potassium permanganate solution for about 15 to 20 minutes, remove and drain the water, and then germinate them. This can improve the seeds' resistance and germination speed.

3. Temperature

American ginseng is suitable for growing in a mild and humid environment, but it also has strong cold resistance. As long as the temperature of the planting site is not lower than minus 12 degrees, it generally will not freeze to death. Generally, when the soil temperature reaches about 5 to 7 degrees, sowing can be carried out, and at this temperature it can begin to grow. When the temperature reaches about 12 degrees, it can emerge. When the temperature is 15 to 20 degrees, it is the most suitable temperature for the growth of American ginseng. Among these, at a temperature of 21 to 22 degrees it will bloom, but the temperature at sowing is best between 12 and 15 degrees. Above 20 degrees, embryo development is not easy, so what we need to pay attention to when planting is the scientific regulation of field temperature.

4. Density

Planting density is also very important for the growth of American ginseng. Generally, under normal conditions, we plant at a density of 30 cm between rows and 20 cm between plants. In this way, the field ventilation of American ginseng will be better, which is more conducive to nutrient absorption and the growth of American ginseng, and later field operations are also more convenient.

5. Light

The growth of American ginseng is very similar to that of ginseng, so their light requirements are also similar. American ginseng is a shade-loving plant, but this does not mean it does not need light. Therefore, we generally do not choose a place with direct sunlight for planting, or we build a shade shed at the planting site. In this way, light can be diffused for slanting and scattered light. So this is also something we need to pay attention to.

6. Humidity

The growth of American ginseng requires a large amount of water. It is a plant that likes humidity and is also tolerant of moisture. The planting humidity should generally be maintained at at least about 55 percent, and when the field moisture is 60 percent, it is the most suitable humidity for the growth of American ginseng. Therefore, we should water reasonably, do a good job in water management, and adjust moisture in a timely manner.

7. Fertilizer use

In terms of fertilizer use, the first thing to pay attention to is the use of base fertilizer. It is mainly to improve the soil and make the planting site more suitable for the growth of American ginseng. We generally use giant fertilizer, peat, soybean cake fertilizer and an appropriate amount of phosphate fertilizer and potassium fertilizer. The amount of fertilizer applied is determined according to the fertility of the planting site. Later, topdressing is generally carried out during the vigorous growth period of American ginseng, mainly with phosphate fertilizer, potassium fertilizer and urea. This period is generally from June to August, and topdressing is needed once a month.
