What is the price of gentian seeds? Introduction to planting methods
Gentian, also known as gentian flower, bitter gall grass, mountain gentian, etc., is a perennial herbaceous plant of the Gentiana genus in the Gentianaceae family. It often grows in hillside grasslands, roadsides, riverbanks, shrubs, forest edges and under forests, and meadows. Its roots and rhizomes are used as medicine. It has a very strong effect in purging excess fire of the liver and gallbladder, and can also calm wind, stop spasms and relieve pain. Let's take a look at gentian seed prices and planting methods below!
How much does a jin of gentian seeds cost?
The price of gentian seeds is about 120 to 160 yuan per jin, but prices vary greatly depending on seed quality, variety, place of origin and market. Gentian has a full-year growth period of about 180 to 210 days. Under natural conditions, it blooms in early August. The flowering period is relatively long, opening sequentially downward from the top of the inflorescence, and the seeds gradually mature. Mature seeds scatter from the opening at the tip of the capsule. Therefore, in early August when the tip of the capsule splits, it can be harvested. After drying, the seeds are removed and stored in a cool, dry place.
Sowing methods for gentian
1. Autumn sowing: Gentian autumn sowing is generally done in November, and it sprouts in the spring of the following year. To sow evenly, an appropriate amount of fine sand or humus can be mixed into the seeds, using drilling.
2. Spring sowing: Gentian spring sowing should first undergo sand storage treatment, that is, after the seeds are harvested, mix them with fine sand at 1:3 and bury them outdoors. After the low-temperature effect of winter, take them out and sow, using drilling.
Planting methods for gentian
1. Site selection and land preparation: Gentian should preferably be planted in relatively moist, flat, sunny sandy soil rich in humus. Areas with high, dry terrain and direct sunlight, or with overly sticky and barren soil, are not suitable for cultivation.
2. Timely weeding: When planting gentian, weeding should not be limited by the number of times. Follow the principle of removing early, removing small, and removing as soon as weeds 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 is transplanted and the seedlings recover, use your hands or a rake in time to remove the compacted surface layer of the bed caused by watering. Do not loosen the soil too deeply, so as not to damage the seedlings or pull them out. Generally, combining weeding with soil loosening 2 to 3 times is sufficient.
4. Timely topdressing: After gentian is transplanted and the seedlings recover, carry out foliar topdressing. Foliar topdressing can be done twice, from after leaf expansion to the bud stage and from flowering to fruiting, using foliar fertilizers such as monopotassium phosphate, Yemianbao, and Fengchansu.
5. Thinning flowers and removing buds: When planting 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.
Pest and disease control of gentian
1. Septoria leaf spot
[Damage] It damages leaves, and in severe cases causes the entire leaf to wither and die.
[Control] Spray once every 10 days after early summer with 50% Tuijunling 1000-fold solution. Before winter, clear away dead branches and fallen leaves to prevent the spread of the pathogen.
2. Underground pests
[Damage] White grubs, mole crickets, wireworms, etc. damage the roots.
[Control] When preparing land, making beds or forming ridges, apply 1000-fold zinc phoxim poisoned soil, or spray and disinfect with 1000-fold zinc phoxim solution.
3. Brown spot disease
[Damage] On severely infected leaves, the lesions merge into patches, causing the leaves to turn brown and yellow and wither, until the plant dies.
[Control] At the early stage of the disease, use 25% carbendazim wettable powder 300 to 600-fold solution, or 50% thiophanate-methyl 1000-fold solution for control.
