How does the Seven Fields reproduce?

Tianqi, also known as Panax notoginseng, Panax notoginseng and Wenzhou Panax notoginseng, is a kind of traditional Chinese medicine mainly produced in Wenshan, Yunnan, so how does it breed? What are the planting conditions?

First, how does Tianqi breed?

Tianqi can be propagated by cutting and sowing, mainly by sowing. The mature and full seeds of 3-4-year-old Tianqi were selected from October to November, and the row spacing was 3 × 2 inch or 3 × 3 inch. After sowing, cover a layer with fertilizer mixed soil, and then cover with a layer of turf to promote the germination of the seeds. The transplant will be almost ready in a year's time.

Second, what are the planting conditions of Tianqi?

1. Soil

Choose the land that is relatively high from the ground, close to the water source, loose soil, not easy to caking, good drainage and a little slope. In the production of Panax notoginseng, the use of soil should be both important and important, and rational fertilization should be carried out according to the characteristics of soil quality and fertility in this area. Through correct farming methods, we can coordinate the conditions of water, fertilizer, gas and heat in soil, create suitable living conditions for microorganisms, accelerate the mineralization of organic matter, promote the increase of nutrients, gradually improve soil structure, improve soil fertility and prevent soil deterioration.

two。 Temperature

When the seedlings of Panax notoginseng break the soil, the temperature should be controlled at about 22 degrees and the soil temperature should be kept at 12 degrees. If the temperature is below zero, it will cause freezing damage to the seedlings. Then during the growth period of Panax notoginseng, the temperature is kept at 24 degrees, and the soil temperature needs to be controlled at about 18 degrees.

3. Moisture content

The growth and development period of Panax notoginseng requires a relatively humid environment, the normal growth of the plant requires to maintain 25-40% soil moisture, and requires the relative humidity in the panax notoginseng garden to reach 70-80%. During the rainy season, more than 80% of the annual precipitation is concentrated in May-October, during which the park can rely on atmospheric precipitation. In years or areas with more annual precipitation, flood control and drainage should be achieved after heavy rain or rainstorm, and the stagnant water in the park should be removed in time.

4. Light

Panax notoginseng is a typical shade plant, the shade degree should be increased appropriately at the initial stage of seedling growth, and the transmittance in the greenhouse is about 25-30%. After entering the rainy season, the number of sunshine hours is less than that in spring, and the total radiation is also lower, while Panax notoginseng is entering a period of vigorous growth, at this time, it is appropriate to reduce shade, increase the light in the garden, the transmittance can be increased to 40%, and specifically control the shade degree in the garden. it depends on the local situation at that time.

The reproduction and planting of Tianqi need some technical support, so friends with planting ideas need to master the technology first.
