Panax notoginseng planting technology and cultivation management, Panax notoginseng planting conditi

37. Planting technology and cultivation management are mainly insect pest control and disease prevention.

Planting conditions: Shading measures should be taken when planting Panax notoginseng, and well-drained, gently sloping humus-rich soil should be provided. Seed treatment:

The seeds were soaked in 800 times the solution of the new high-lipid film, and the beam infiltration type was disinfected to improve the disease resistance of the seeds. Field management: Weeding is required regularly at the seedling stage to prevent weeds from competing with the plants for nutrients.

1. Planting conditions

Panax notoginseng is a negative plant and is sensitive to light, so when planting, it is necessary to do a good job of shading measures to avoid strong light burning the leaves, resulting in dwarf plants, and notoginseng likes a moist environment, is not tolerant to drought and severe cold, and is suitable for growing in well-drained, gently sloping and humus-rich soil.

2. Seed treatment

From October to November every year, select high-quality Panax notoginseng fruits, remove their skins, wash them with water, and put them in a ventilated place to dry them, and then soak the seeds in the new high-fat film 800 times the liquid for disinfection treatment, improve the disease resistance of the seeds, and strengthen the strength of the root system.

3. Field management

In the seedling stage of Panax notoginseng, weeding needs to be carried out regularly, so as not to compete with weeds and plants for nutrients, and take transplanting measures after the seedlings, and when the seedlings rise, we must avoid damaging the spores and roots of Panax notoginseng, so as not to affect the growth of plants, in addition to the later maintenance process, timely weeding, soil cultivation.

Panax notoginseng is a precious Chinese medicinal material, which was mainly produced in Yunnan, Guangxi, Guangdong, Sichuan, Guizhou, Hunan and other places in history. In recent years, the safety production of Sanqi has attracted more and more attention. In order to make the production of Panax notoginseng meet international requirements, it is necessary to shift the production focus from the output of Panax notoginseng to the quality of Panax notoginseng, so as to ensure that the product has the characteristics of high saponins, low pesticide residues and low heavy metal content.

Prevent premature aging, reduce the harm of drugs and fertilizers, toxins, loosen soil, alleviate plant terminal cells, delay plant senescence and premature senescence, increase the number of harvests, increase yields, and increase value. Disease resistance and fertilizer conservation, active polypeptide immunoprotease can effectively enhance the immune system of crops, play a two-way role in regulating immune stress resistance, and enhance the cold and drought resistance of crops. Long-term use helps reduce morbidity.

As a perennial herbaceous plant, Panax notoginseng is generally 30-50cm tall, with erect stems, no branches, fleshy roots are more developed, and the roots are vigorous. Panax notoginseng petioles are short, the leaves are green or light green, the edges have fine teeth, generally sowing in November-December, flowering in July-August of the following year, and fruiting in August-September of the following year. When choosing seeds, you should choose 3 or 4-year-old fruits, full of particles, free of pests and diseases, and ripe and red fruits to pick, put the fruits in a sieve, rub off the peel, and take out the white seeds inside.

Panax notoginseng is generally planted from November to March of the following year, during which the temperature is suitable. Choose sandy loam soil and set up a greenhouse before planting to facilitate subsequent growth. Transplanting is the same as any other plant, just pay attention to the light in summer.

This is mainly due to the high temperature, sometimes rainy days, and drastic changes in soil temperature affect the roots, resulting in the death of fallen leaves. The dry weather is beneficial to the growth of Panax notoginseng; Too much rain will affect its growth; However, it was sunny for about 10 days, and it rained for a few days, which did not have much impact on the growth of Panax notoginseng.

After sowing the seeds, they should be covered with soil mixed with fertilizer, and then covered with a layer of turf, which can help the seeds germinate quickly. The ground is deep and ploughed, the foot fertilizer is applied, and the farmer's fertilizer is the best, and then the small ridges are raised and covered with plastic film, which is conducive to moisture preservation and drought resistance. The planting distance should be appropriate, about 30 cm, with a single row of small ridges and a double row of slightly wider.

Water immediately after planting to ensure the survival rate of seedlings.
