Detailed Explanation of the Latest Planting Methods and Cultivation Techniques for Notoginseng

Notoginseng is a traditional Chinese medicine used for stopping bleeding, nourishing blood, and boosting immunity. It can be used to brew tea, and can also be used to make medicinal soups and herbal dishes. It can also be used as medicine, with extremely high value. Notoginseng is grown in many places in our country. Today we will mainly learn about how to grow notoginseng well.

1. Land preparation and fertilization

The planting site for notoginseng is generally chosen in a place with a slight slope, which facilitates drainage and irrigation. At the same time, the water source near the planting site should be relatively abundant. The soil is best if it is humus-rich soil with abundant organic matter, or sandy soil or loam. It should not be planted in heavy clay soil, as such land is very prone to compaction and is not suitable for the tuber growth of notoginseng. At the same time, the planting site must not be a plot whose previous crop was a solanaceous crop. The planting site must be left vacant for at least one year before planting. During land preparation, deep plowing is required, and before planting the soil needs to be disinfected and sterilized. Use about 5,000 jin of farmyard compost per mu as base fertilizer, then make the beds and dig the drainage ditches.

2. Sowing and seedling raising

Sowing is carried out every year in October or November. Before sowing, the notoginseng seeds need to be screened, and the seeds should be disinfected with New High Lipid Film. This can increase the germination rate of the seeds, and at the same time can isolate viruses without affecting the germination of the seeds. Sowing is generally done by dibbling with a row spacing of 6 cm and a plant spacing of about 5 cm. Finally, a layer of rice straw needs to be covered on top, which can maintain soil moisture and also have an insulating effect.

3. Seedling stage management

The main things to pay attention to in seedling stage management are field water management and weeding. When the weather is relatively dry, watering should be done frequently, generally once every three to five days or so. Next, when there is a lot of rain, the field drainage system should be dredged in time for drainage. Then, weeding should be carried out regularly, generally by manual pulling of weeds. Finally, when necessary, supplemental fertilizer should be applied to maintain the normal growth of notoginseng.

4. Field management

First, we need to transplant the seedlings in the field. Generally, transplanting can only be carried out after a one-year seedling raising stage. When pulling up the seedlings, be careful not to damage their roots. When selecting seedlings, remove weak seedlings and diseased seedlings, then plant them with a row spacing of 20 cm and a plant spacing of 15 cm. After planting, water in time, which can increase the survival rate of notoginseng. Then, in summer when the sunlight is stronger, build a shade shed so as not to affect the growth of notoginseng. During the growth process in the weather, our supplemental fertilization needs to follow the principle of applying fertilizer many times in small amounts, so that the notoginseng fruits can be plump. Also, in order to prevent unnecessary nutrient consumption, all flower stalks can be removed, so that nutrients can be supplied in a concentrated way to the underground roots and promote the rapid growth of the rhizomes.

5. Pest and disease control

The most common pests and diseases of notoginseng include damping-off disease, anthracnose, root rot, as well as aphids and scale insects. For a series of fungal infection diseases caused by excessive field moisture combined with relatively high temperatures, we can usually use Bordeaux mixture or chlorothalonil and carbendazim for control, while for aphids and scale insects we can use dimethoate emulsion for control.
