How to plant the latest seeds of Panax notoginseng?

Panax notoginseng is a perennial erect herb of Panax ginseng of Acanthopanax family, distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. It was born at 1200-1800 meters above sea level. It has remarkable effects of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain. It has a good reputation of "Jinbu" and "Southern Divine Grass". It has a very high cultivation value. Let's take a look at how to plant Panax notoginseng seeds.

Germination conditions of Panax Notoginseng

The germination temperature of Panax notoginseng seeds is 10: 30 ℃, the optimum temperature is 20 ℃, and the dormancy period of Panax notoginseng seeds is 45-60 days. During dormancy, the seedlings need to be treated with low temperature for a period of time before they germinate, and they are very sensitive to light. Traditionally, it is believed that 30% of natural light is needed for normal growth and development, so the shade shed of Panax notoginseng has a saying that "30% of the light is transparent and 70% is shaded." According to the latest research, the most suitable transmittance of Panax notoginseng shed is 812%, and the growth of more than 17% Panax notoginseng will be adversely affected.

Seed treatment of Panax Notoginseng

The seeds of 3-year-old plants with strong growth and free of diseases and insect pests are generally selected from Panax notoginseng, and the seeds are collected and washed and sowed in time when the fruit is ripe from November to December, because the germination rate is greatly reduced after the seeds have been stored for a week. Before sowing, disinfect with 0.2-0.3% Baumedu sulphur mixture for 10 minutes, or with 200-300 times zinc for 15 minutes, and then sow seeds.

Seed sowing of Panax notoginseng

2 ~ 3 months before planting, the selected land was ploughed many times, so that the soil was fully weathered and broken. Plough and rake again before sowing, then the height of the border is 1820 cm, the width of the border is 1 m, the basic fertilizer is 3000kg / mu, mix well with the soil, level the border surface, open the hole according to the row spacing of 6 cm × 6 cm, the hole depth is 1.5 cm, put 1 seed in each hole, cover the soil with straw to avoid soil consolidation. The seedlings sown in winter in the south emerged in 3 months and emerged in 4 months. About 100000 seeds per mu (weight 8.5kg) could be sown and transplanted in the nursery after one year of cultivation.

Seedling transplanting of Panax notoginseng

Panax notoginseng must be transplanted one year after growing in the seedbed (commonly known as "seed"), and the new land must be arranged in the same way as the seedbed, preferably during the heavy snow or the Winter Solstice. Dig up the "seeds" of the seedling bed, cut off the stems and leaves, commonly known as "Kezi" into the hole, apply a pinch of mixed fertilizer, cover the local area by 24 × 20 cm or 27 cm × 20 cm, the depth of the ditch is 3 cm 5 cm, when planting seedlings, make the seedling and the bottom of the ditch at an angle of 20 to 30 degrees, cover the soil while planting, the thickness is not to reveal the bud head, should not be too thick, and then cover the broken grass about 1 cm 1.5 cm thick, with no soil as the principle.
