Matters needing attention in planting Panax notoginseng

1. Planting site selection

It is best to plant Panax notoginseng in mountainous areas with high topography and convenient drainage and irrigation, and the loam with strong drainage capacity is better.

2. Soil preparation and fertilization

Ploughing should be carried out before sowing, and the depth of ploughing should be about 25-30cm. After ploughing, fertilizer should be applied proportionally, and then the bed should be made.

3. Sowing seeds

If it is planted in the north, the best sowing time is March-April; in the south, the sowing time is between the end of October and the end of November.

Select the pest-free, full, neat and red seeds, soak the selected seeds in 30% benzimidazole 44 solution for 15 minutes, then take the soaked seeds to a dry place to dry, then mix the dried planting and plant ash evenly, put them in a place of 25-28 ℃ for germination; wait for more than 90% of the seeds to germinate. Hole sowing was carried out on the finished border surface according to plant spacing of 10-15cm, row spacing of 15-20cm, and bamboo with a height of 2.5m and fist thickness was inserted every five holes after sowing, and then a layer of sunshade net was covered on the pillar.

4. Daily management

Carry out the work of seedling intercropping, fertilization, drainage, watering and weeding in time, and harvest every October when the fruit is full.

5. Disease control

Black spot: at the initial stage, the stems and leaves of the diseased plant will slowly appear brown spots, and finally spread to the whole plant. The planting can be disinfected before planting, and at the initial stage of the disease, 80% chlorothalonil powder 1000 times solution can be sprayed on the diseased plants for prevention and treatment.

Blight: usually occurs at the base of the stem, the base of the stem will show yellow spots in the early stage of the disease, and the diseased part of the stem will be broken in the later stage. 35% Likuling 800 times solution can be sprayed on the diseased stem for control.
