The Latest High-Yield Cultivation Techniques and Methods Tutorial for Panax notoginseng

Panax notoginseng is a famous and important traditional Chinese medicinal herb, mainly harvested for its underground rhizome for medicinal use. Its main producing area is currently Wenshan, Yunnan. Panax notoginseng is mainly used to treat diseases such as coughing up blood and blood in the stool. It belongs to the Araliaceae family, genus Panax, so it is a precious medicinal herb with excellent efficacy. Artificial cultivation has been practiced for a certain period of time now, but to cultivate Panax notoginseng, you need to achieve a high yield in order to obtain higher economic benefits. Let us learn about the specific high-yield cultivation techniques together.

1. Site Selection and Land Preparation

It is best to choose gentle slope land with a gradient of about 10 degrees for planting. Gentle slopes drain well and do not accumulate water. The soil is best if it is humus-rich soil with plenty of fallen leaves. It is best if the land has not previously been planted with solanaceous vegetables; land that has been planted with soybeans is the best. Before plowing, you can spread grass over the entire field and burn the field to disinfect, sterilize, and kill insects. When plowing, apply 2000 jin of organic fertilizer per mu. Plow the land, level the soil, and make beds, preferably 1.2 m wide, with length determined by the terrain.

2. Seeds and Seed Disinfection

Each year during the seed-setting period, select robust mother plants to pick seeds. Screen the seeds and keep the plumpest, best-colored, and intact seeds for storage. Seeds easily lose viability when dried, so it is best to store seeds in clean, shaded indoor stratification. Before sowing, soak the seeds in 50 degree hot water with stirring for 20 minutes, then soak in seaweed liquid for 10-plus minutes, drain, and then sow.

3. Sowing and Seedling Raising

Directly sow in rows, sowing evenly in the furrows, cover with soil mixed with organic fertilizer, and then cover with rice straw to maintain soil moisture. You can also water and then cover with gray plastic film, which has good heat preservation and moisture retention. Water every day before emergence. It is best to raise seedlings in a greenhouse, and then during greenhouse seedling raising, temperature and humidity can be regulated. After emergence, water less. After the seedlings are uniform, thin them once, removing weak and diseased seedlings. Water before transplanting, with a plant spacing of 15 cm and row spacing of 20 cm.

4. Field Management

Weeds must be removed as soon as they are found; they must not compete for nutrients. Panax notoginseng has shallow roots and roots are easily exposed after rain, so soil should be hilled up to cover them promptly when found. Strong light is not conducive to growth, so shade frames should be built for planting, but too little light transmission can also cause disease and poor growth. Therefore, the final light transmission rate should be about 50%. Fertilization should be applied in small amounts multiple times, mainly potassium fertilizer and phosphorus fertilizer. During the seedling stage, plant ash can be broadcast twice, and during the expansion stage, apply 30 jin of calcium fertilizer. When flower shoots emerge, they can be pinched off to reduce consumption. Mainly prevent and control damping-off disease, blight, and mites.

5. Harvesting and Processing

To meet the standard for sale, Panax notoginseng must be harvested and processed, dried properly, and then sold. When harvesting, clean off the attached soil, then trim the fibrous roots, sun-dry, rub, and then sun-dry thoroughly or directly dry. Place it in rice husks and bury it for a period of time; once the surface is glossy, it is ready.

For high-yield Panax notoginseng cultivation, the key is actually to do better in the details of the planting process, then manage more meticulously and thoughtfully, provide the most suitable environmental conditions for growth and development, ensure sufficient nutrition, maintain good growth vigor, and then seize the key management period during the flowering and expansion stage.
