How to choose the seeds of Panax notoginseng? What are the methods of raising seedlings?

Panax notoginseng, also known as Jinbu, has a long history of cultivation in China, mainly distributed in Yunnan, Guangxi and other places, among which Panax notoginseng produced by Wenshan in Yunnan is famous at home and abroad. Planting Panax notoginseng, raising seedlings is very critical, if the work of raising seedlings can not be done well, the yield will be affected. So how to choose the seeds of Panax notoginseng? What are the methods of raising seedlings? Next, let's have a look with the editor.

How to choose the seeds of Panax notoginseng?

To plant Panax notoginseng, you must first choose a good seed. Select healthy and well-developed seeds for sowing, full seeds, stored nutrition, strong germination potential, strong seedlings, strong disease resistance.

You can gently rub off the peel, wash the seeds with flowing tap water, remove the adhesives on the peel, pulp and seed surface, and fish out floating empty seeds and stunted seeds. After rinsing, put it in a cool and ventilated place and blow-dry the surface water of the seed.

After the fruit is harvested, the peel and pulp should be removed as soon as possible, otherwise it will cause seed decay and fever, resulting in low germination rate, weak germination potential, and even loss of activity or decay.

The seeds of Panax notoginseng have the characteristics of recalcitrant seeds, which are easy to lose their vigor after losing water. Therefore, in the seed drying process should be carried out in a cool place, do not lose too much water in the sun.

What are the breeding methods of Panax notoginseng?

1. Land selection and preparation

Choose the shady gentle slope on the back, the slope is about 5-10 degrees, if the slope is too steep, the soil erosion is serious, on the contrary, the drainage in the plain area is not smooth, and the root is easy to rot. The soil chooses red soil or brown red soil with good drainage, loose texture and aggregate structure, the sandy loam that can regain moisture at night is better, while heavy clay soil is easy to cause root rot, so it is not suitable to choose.

2. Sowing seeds at the right time

After the fruits of Panax notoginseng are harvested, the treated seeds can be sown immediately, or they can be stored for 45-60 days before sowing. Generally speaking, the best sowing time is from late December to January of the following year.

3. Seedling stage management

After sowing, Panax notoginseng usually does not emerge until March to April, during which there is no need for watering, some drought time is longer, watering is carried out according to soil moisture, and stagnant water is discharged in time after rain. The management of seedling stage after unearthed mainly includes irrigation, light transmission, topdressing and so on. Irrigation at seedling stage is determined according to soil moisture, at this time, the soil water content should be higher than that before emergence, keep the border surface moist, so that the root system can absorb enough water, but avoid flood irrigation and timely drainage after heavy rain to reduce the occurrence and spread of diseases and insect pests.

4. Points for attention

Don't sow too much. The germination ability of Panax notoginseng seeds is weak, so it is not suitable to plant too deep, otherwise it is not easy to emerge seedlings and is prone to the problem of lack of seedlings.

The above is the introduction of Panax notoginseng, but due to the continuous cropping of Panax notoginseng, the disease and insect pests in the old producing areas are becoming more and more serious, so farmers should pay attention to it.
