Detailed Explanation of Glehnia Root Seed Prices and Planting Methods
Glehnia root is a perennial herbaceous plant of the genus Adenophora in the Campanulaceae family. It mostly grows in low mountain grasslands and rock crevices, and is distributed in Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan and other places. As a medicinal herb, it has the effects of nourishing yin and clearing heat, moistening the lungs and resolving phlegm, and benefiting the stomach and promoting fluid production. It is divided into southern glehnia root and northern glehnia root, and its cultivation value is extremely high. Let us take a look at glehnia root seed prices and planting methods together below!
How much is glehnia root seed per jin?
The price of southern glehnia root seeds is about 20 to 30 yuan per jin, and the price of northern glehnia root seeds is about 30 to 40 yuan per jin. Prices vary depending on variety, quality, place of origin and purchase quantity. Generally, about 2 jin of seeds are used per mu. Glehnia root is divided into southern glehnia root and northern glehnia root. Southern glehnia root is Adenophora verticillata or Adenophora stricta, plants of the genus Adenophora in the Campanulaceae family, distributed in Jiangsu, Hunan, Anhui, Zhejiang, Jiangxi and other places, while northern glehnia root is Glehnia littoralis, a plant of the genus Glehnia in the Apiaceae family, distributed in Shandong, Hebei, Liaoning, Inner Mongolia and other places.
Sowing Methods for Glehnia Root
1. Site selection and land preparation: For glehnia root cultivation, choose flat land or gentle slopes with sandy loam or loam soil that is sunny, fertile, rich in humus and well-drained. Apply 2000 to 2500 kg of compost or barnyard manure per mu, plus 20 to 50 kg of phosphate fertilizer as base fertilizer. After spreading the base fertilizer evenly, plow deeply 30 to 40 cm, rake fine and level to make beds, with bed width of 1 to 1.3 m.
2. Sowing method: Glehnia root is propagated by seeds, divided into spring sowing and autumn sowing. Spring sowing is in early to mid-April, and autumn sowing is before freezing in November. Open shallow furrows 4 to 6 cm deep at a row spacing of 30 to 40 cm, evenly scatter the seeds in the furrows, cover level with fine soil, press lightly and then water. If conditions permit, cover with a layer of grass to preserve warmth and moisture and promote germination. Spring-sown seeds emerge in about 20 days, and autumn-sown seeds emerge in March to April of the following year.
Planting Methods for Glehnia Root
1. Thinning and final singling of seedlings: Thin glehnia root seedlings when they have 2 to 3 true leaves, to the extent that the seedling leaves do not overlap. Final singling is done when the seedlings are 12 to 15 cm tall, with a plant spacing of 10 to 15 cm. Water after thinning and apply appropriate topdressing.
2. Cultivation and weeding: During the seedling stage of glehnia root, choose cloudy days to pull out weeds. After final singling, loosen the soil and weed together with topdressing. After the plants close the beds, weeding should be stopped to avoid breaking stems and branches. Pay attention to drainage on rainy days, and water appropriately during drought.
3. Reasonable fertilization: During the seedling stage of glehnia root, apply 10% diluted human manure or 2% urea water. Apply topdressing once after final singling. Before winter, spread 1000 kg of farmyard manure per mu. Apply topdressing once after emergence in the second year. Before flowering in June to July, apply 1000 kg per mu mixed with a small amount of phosphorus and potassium fertilizer.
4. Timely topping: From the second year onward, glehnia root plants grow rapidly. To reduce nutrient consumption and promote root growth, topping can be done when the plants are 40 to 50 cm tall.
5. Harvesting and storage: Glehnia root is harvested 2 to 3 years after sowing. In autumn, dig out the roots, remove stems, leaves and fibrous roots, wash off the soil, scrape off the outer skin with a bamboo strip while fresh, slice, and dry in the sun.
Pest and Disease Control of Glehnia Root
1. Root rot
[Damage] Root rot is a disease caused by fungi, damaging the roots, and mostly occurs in rainy seasons.
[Control] Clean the garden, treat diseased holes with lime, and spray the root and stem area with 50% Tuzet 500-fold solution.
2. Brown spot disease
[Damage] Brown spot disease is a fungal disease caused by Rhizoctonia solani, damaging the leaves.
[Control] Drain water and clean the garden, and spray the leaf surface with 1:1:1000 Bordeaux mixture or 65% Amobam wettable powder 500-fold solution.
3. Aphids
[Damage] They damage plants by sucking sap from stems.
[Control] Clean the garden in winter, and spray 50% fenitrothion 1000 to 2000-fold solution or 8% dichlorvos emulsion 1500-fold solution.
4. Cutworms
[Damage] The larvae bite off the roots and stems of plants during the seedling stage, causing missing seedlings, and in severe cases causing large areas of dead and missing seedlings.
[Control] Clean the garden, apply fully decomposed manure, or use black light traps, or catch them, or use poisoned bait to trap and kill them. During damage, spray with 90% trichlorfon 1000 to 1500-fold solution.
