Matters needing attention in the latest planting of American ginseng

American ginseng is a kind of American ginseng introduced from Europe and America, also known as American ginseng. It has the functions of tonifying qi and nourishing yin, clearing heat and promoting fluid, eliminating fatigue, enhancing memory and relieving insomnia. American ginseng is a relatively expensive medicinal material. In China, the main producing areas of American ginseng are Shaanxi, Jilin, Heilongjiang and other places, so how is American ginseng planted? What do you need to pay attention to when planting? Next, let's learn about the points for attention in the cultivation of American ginseng.

1. Soil

The soil of all kinds of American ginseng should generally choose more fertile farmland, and the acidity and alkalinity of the soil should be tested before planting, followed by sandy or loam soil which contains a lot of humus and loose soil. at the same time, the first stubble of farmland can not be radish, cabbage, melons, fruits and eggplant and other crops, so we must pay attention when choosing planting land, and finally, the planting land should be chosen in the shelter zone. So as not to affect the normal growth of American ginseng.

2. Sprouting

When planting American ginseng, attention must be paid to the treatment and germination of the seeds. Generally, carbendazim can be used for disinfection and sterilization, soaking for about half an hour, and then rinsing the seeds in clean water. Finally, the seeds are put in an environment of 18 to 20 degrees Celsius for germination, or soaked in potassium permanganate solution for about 15 to 20 minutes to drain water. This can improve the resistance of seeds and the speed of budding.

3. Temperature

American ginseng is suitable for growing in a mild and humid environment, but it also has strong cold tolerance. As long as the temperature of the planting ground is not less than 12 degrees below zero, it generally will not freeze to death. Generally, it can be sown when the temperature of the soil reaches about 5 to 7 degrees. At this temperature, it can begin to grow, and seedlings can emerge when the temperature reaches about 12 degrees. The most suitable temperature for the growth of American ginseng is when the temperature is 15 to 20 degrees, in which the temperature will blossom when the temperature is 21 or 12 degrees, but the temperature when sowing is preferably between 12 and 15 degrees, and higher than 20 degrees is not easy for the development of embryos, so what we should pay attention to when planting is the scientific regulation of the temperature in the field.

4. Density

The planting density is also very important to the growth of American ginseng. Generally, under Qingkang, we will plant according to the density of row spacing of 30 cm and plant spacing of 20 cm. In this way, the field permeability of American ginseng planted will be better. It is more conducive to the absorption of nutrients and the growth of American ginseng, while the later field operation is also more convenient.

5. Lighting

The growth of American ginseng is very similar to that of ginseng, so their demand for light is similar. American ginseng is a negative plant, but this disease does not mean that it does not need light. therefore, we generally do not choose to plant in places where there is direct sunlight, or to build a shade in the planting area, so it can be light divergence for oblique and scattering, so this is also a place that we need to pay attention to.

6. Humidity

American ginseng needs a lot of water for its growth. it is a kind of plant that likes wetting and is resistant to humidity. the humidity of planting should be kept at least about 55%, and the moisture in the field is the most suitable humidity for the growth of American ginseng at 60%. So we should water reasonably, do a good job of water management, and make different moisture in time.

7. Use fertilizer

The first thing to pay attention to in the use of fertilizer is the use of base fertilizer, which is mainly to improve the price of the soil and is more suitable for the growth of American ginseng. We generally use huge fertilizer, peat and bean cake fertilizer and the right amount of phosphate and potash fertilizer. The amount of fertilizer is determined according to the fertility of the planting land. In the later stage, topdressing is usually carried out in the peak growth period of American ginseng, mainly with phosphate fertilizer, potash fertilizer and urea, which is usually from June to August, and topdressing is needed once a month.
