How to plant potted Panax notoginseng?

Panax notoginseng is a perennial erect herb of Araliaceae, which is distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. With its roots used in medicine, Panax notoginseng has a significant effect of promoting blood circulation and removing blood stasis, detumescence and pain. It has the reputation of "Jinbu" and "Southern divine grass". It is the most precious of traditional Chinese medicine. let's take a look at how to plant potted Panax notoginseng.

Growth habits of Panax Notoginseng

Like warm and shady and wet environment, afraid of cold and heat, but also afraid of water. The soil is loose red soil or brown red soil, slightly acidic, and the annual average temperature is 16.0-19.3 ℃. During the growth period, if the temperature lasts for 3-5 days and is above 30 ℃, the plant is prone to disease. The cultivation land should choose the east slope, and the slope is 515 °. Planting in low-lying land is prone to root rot.

Breeding methods of Panax Notoginseng

1. Seed selection: Panax notoginseng uses seeds to propagate, select seeds from three-year-old plants, collect seeds when a large number of fruits mature and turn red from November to December, remove the pericarp, and sow the mature seeds without diseases and insect pests in winter immediately. If it is too late to sow, the fruit should be spread out in a sieve, about 3 cm thick, and can be stored in a ventilated and cool place for 7 to 10 days. For outward transportation, the pericarp should be removed, cleaned, mixed into 2 times wet sand and stored in wooden boxes.

2. Soil preparation: the sowing land and transplanting land of Panax notoginseng should choose loam or sandy loam with high topography and good drainage, sunny gentle slope (slope 515 degrees) or uncultivated land. Ploughing several times in autumn, and then through 3 ploughs and 3 rakes, rake the soil fine, and then make a border with a height of 25 cm 35 cm and a width of 100 cm 120 cm. The border surface is made into a comb back shape, and the drainage ditch between the two borders is 45 cm 60 cm.

3. Sowing: before sowing and planting, Panax notoginseng applied 3000-5000 kg mature organic fertilizer per mu, and added 25-35 kg calcium superphosphate or calcium magnesium phosphate fertilizer, spread the fertilizer evenly on the border surface, and then turned into the soil layer 4-6 cm deep. In the south, winter sowing and on-demand sowing are mostly used, with row spacing of 6 cm and plant spacing of 5 cm. After sowing, they are covered with fine fertile soil to cover no seeds. Cover with weeds to avoid soil consolidation. It takes about 3 months to grow up and 4 months to come out. If spring sowing is carried out in the north, the seeds must be stored in wet sand, sown with germinated seeds, and emerge one month after sowing.

How to grow potted Panax notoginseng?

1. Watering: Notoginseng seedlings will not emerge until March to April after sowing, during which artificial watering should be carried out (if the soil has night tide, it can not be irrigated). The method should be watered to the border surface with a sprinkler, usually 2 or 3 times a month until the rainy season comes.

2. Lighting: the light transmittance requirement of one-and two-year-old Panax notoginseng is low, which is generally about 10%, while that of three-year-old Panax notoginseng requires a strong light transmittance, which is about 15%. By adjusting the light transmittance in the shade shed, the root weight of a single plant can be increased.

3. Topdressing: panax notoginseng bud stage (June) and flowering stage (September) are the peak of fertilizer absorption, so topdressing should be carried out at this time. Topdressing is mainly farm manure, supplemented by a small amount of compound fertilizer.

Note: the culture period of Panax notoginseng requires a relatively humid environment, the normal growth of Panax notoginseng requires to maintain 25% soil moisture, and requires the relative humidity of the basin soil to reach 70% 80%. The artificial regulation of moisture is mainly in winter and spring, when the weather is sunny, the sunshine is sufficient, the precipitation is scarce and the wind speed is large, the evaporation power is strong, and the soil moisture decreases rapidly. at this time, in addition to artificial irrigation, we must also pay attention to proper management. use bedding box grass to shade to maintain humidity.
