Gentian is a plant of the genus Gentiana in the family Gentianaceae. It has the effect of clearing heat and drying dampness, and purging excess fire of the liver and gallbladder. It mainly treats hypertension, dizziness and tinnitus, cholecystitis, acute infectious hepatitis, genital dampness and itching, damp-heat jaundice, sores, boils and abscesses, bitter taste in the mouth and infantile convulsions, and is a good medicine for protecting the liver and promoting gallbladder function. Nowadays many people cultivate gentian

What are the methods for cultivating gentian

1. Propagation methods

Gentian can be propagated both sexually and asexually. Sexual propagation has relatively strict technical requirements: after sowing, the soil moisture content should not be lower than 30%, the surface air humidity should be 60-70%, and the suitable temperature is 25-28 degrees C; germination begins in about 7 days, and the seed germination rate is relatively high when the soil pH is 6.3-7.8. Asexual propagation can use root division propagation and aboveground stem cutting propagation. For root division propagation, dig out the underground part in autumn, cut the rhizome into 3 pieces, and use them together with the fibrous roots as planting material; for aboveground stem cutting, take branches from perennial plants before bud differentiation, use every 3 nodes as cutting material, make a slanted cut below the lower node, remove the two leaves at the end node, and immediately immerse 2-3 cm of it in a mixed solution of compound hormones GA, BAP and NAA at 1 ppm each in equal amounts; after 48 hours, use it as cutting material. Light promotes seed germination.

2. Planting methods

Gentian planting methods: Seed seedling raising: sow in spring. Before sowing, wash the seeds with water, mix in an appropriate amount of fine sand, and broadcast them on a leveled seedbed. The sowing rate is 1-1.2 grams per sq m. After sowing, cover with grass to maintain temperature and humidity, and do not let the temperature exceed 30 degrees C. After 2 years of growth, transplant in spring or autumn. Open furrows on prepared large ridges; the furrow depth depends on the size of the planting material, the plant spacing is about 15 cm, and the soil covering depth is 3-4 cm.

Root division propagation: Plant the propagation material on prepared large ridges in autumn, with a plant spacing of about 10 cm and a soil covering depth of about 5 cm. After planting, water thoroughly to preserve soil moisture.

Cutting propagation: Insert the prepared cutting material into a leveled seedbed, with a plant and row spacing of 10 x 10 cm and a cutting depth of 2-3 cm, then water immediately. The soil temperature is 18-20 degrees C, and roots can form in about 3 weeks.

How to cultivate gentian? Gentian sowing methods and cultivation techniques

Gentian, also known as longdan, dancao, kudancao, etc., is a perennial herbaceous plant of the genus Gentiana in the family Gentianaceae. Gentian is a common Chinese medicinal material in China, and its rhizome is also used as medicine. It has effects such as clearing heat and drying dampness, purging liver fire and calming convulsions, and promoting gallbladder function and protecting the liver, and is well received by the market. So how is gentian cultivated? The sowing methods and cultivation techniques of gentian are introduced as follows.

I. Sowing methods for gentian

1. Autumn sowing: Gentian autumn sowing is generally carried out in November, and it sprouts in the following spring. To make sowing uniform, mix an appropriate amount of fine sand or humus into the seeds and use drilling.

2. Spring sowing: Gentian spring sowing should first undergo sand storage treatment, that is, after collecting the seeds, mix them with fine sand at 1:3 and bury them outdoors. After being affected by low winter temperatures, take them out and sow, using drilling.

II. Cultivation techniques for gentian

1. Site selection and land preparation: For gentian, it is suitable to choose relatively moist, flat terrain, sunny, sandy soil rich in humus. Areas with high and dry terrain, direct sunlight exposure, overly sticky soil, or poor soil are not suitable for cultivation.

2. Timely weeding: When cultivating gentian, weeding should not be limited by the number of times. Follow the principle of removing early and removing small, and remove weeds as soon as they are seen. Do not wait until weeds grow up and form a weed infestation before pulling them, as this both wastes labor and damages the seedlings.

3. Reasonable loosening of soil: After gentian transplanting and seedling recovery, the surface crust of the seedbed caused by watering should be removed promptly by hand or with a rake. Do not loosen the soil too deeply, so as to avoid damaging the seedlings or pulling them out. Generally, loosening the soil 2-3 times in combination with weeding is sufficient.

4. Timely topdressing: After gentian transplanting and seedling recovery, carry out foliar topdressing. Foliar topdressing can be done twice, from after leaf expansion to the budding stage and from flowering to fruiting, using foliar fertilizers such as monopotassium phosphate, yemianbao and fengchansu.

5. Flower thinning and bud removal: When cultivating gentian, in order to reduce nutrient consumption, promote root material accumulation, accelerate rhizome growth and improve cultivation benefits, all flower buds should be removed after budding for fields not used for seed production.

[Editor's conclusion] Gentian is an alpine plant and likes a moist and cool climate, so special attention is needed during cultivation. The above has introduced the sowing methods and cultivation techniques of gentian for everyone, and I hope it can be helpful to everyone!

Cultivation methods for gentian

Soil selection:

Choose relatively moist sandy soil rich in organic matter.

Environment selection:

Gentian likes ample sunlight, so a place where sunlight can shine directly can be chosen.

Preparation before planting:

The base fertilizer should be sufficient, then level the soil surface and make furrows for planting gentian.

Care after planting:

After the seeds sprout into seedlings, remove unhealthy seedlings and those with weaker growth, leaving relatively sturdy seedlings for cultivation.

During the seedling stage, weed frequently. They can be pulled directly; do not let weeds absorb soil nutrients and cause the seedlings to lack nutrients. Even less should you wait until the small weeds grow up before removing them, as this can easily damage the roots of gentian.

If the soil cracks or clumps, loosen the soil in a timely manner. When loosening the soil, be careful not to go too deep, otherwise it is easy to damage the seedlings and also pull them out of the soil. Transplanting and final planting can also be carried out when loosening the soil. After transplanting, loosen the soil another 2 to 3 times.

After transplanting, carry out one topdressing, and spraying can be used to apply fertilizer to the leaf surface. Carry out another topdressing at budding and at flowering and fruiting. Over 3 to 4 years, apply fertilizer to the soil once, and after fertilizing, level the soil.

Flower thinning and bud removal

For fruiting plants, if the number of flowers is far greater than the number of fruits, remove and prune the flowers in time to avoid consuming unnecessary nutrients. If not pruned in time, the fruits that finally form will also fall before reaching full formation. Remove them.

Profit analysis

After sowing, gentian grows in the field for 3 years before being harvested. The yield of fresh gentian is 500 kg per mu, and the annual yield of dried gentian is 160 kg. At a market price of 70 yuan/kg, the output value is 11,200 yuan. Net profit: 3,360 yuan. If a family farm cultivates gentian over an area of 100 mu, it can obtain an annual net profit of 336,000 yuan.
