A Detailed Guide to the Cultivation Techniques and Management Methods of Solidago decurrens
Solidago decurrens is a perennial herb of the Asteraceae family. It is a traditional Chinese herbal medicine in China, with the effects of dispelling wind, clearing heat, detoxifying and reducing swelling, and it is widely used. It is rich in flavonoids and has excellent anti-cancer effects. Due to its high medicinal value, people harvest it extensively, and wild plants are increasingly dwindling. It is now a rare plant, and it is cultivated in many regions. So how should Solidago decurrens be grown? Let's take a look together.
1. Site selection and land preparation
Solidago decurrens prefers a cool and humid climate and is cold-tolerant. It is best planted in loose, fertile, well-drained sandy loam rich in humus. The plot is required to have not been planted with crops such as garlic or onions for more than two years. After selecting the site, plow it repeatedly to allow the soil to weather naturally, remove weeds, and apply decomposed farmyard manure as base fertilizer according to the soil fertility status. Mix it evenly with the soil, then make beds and raise ridges, dig drainage ditches, and wait for planting.
2. Propagation methods
Solidago decurrens can be propagated by seeds and by division, but seed propagation is generally used in production. In November-December, cut off the mature fruiting branches, place them in a cool place to dry naturally in the shade, thresh them, remove impurities, and store them for later use. In March of the following year, begin sowing and raising seedlings. Open furrows on the bed surface at a row spacing of 33 cm, sow the seeds evenly into the furrows, cover with a thin layer of soil, just enough to cover the seeds, press gently with your hands, then water and cover with grass to retain moisture.
3. Transplanting
Generally, seedlings emerge 10-15 days after sowing. When the seedlings emerge, promptly remove the covering grass. When the seedlings grow to 3 cm, promptly loosen the soil, weed, and apply supplemental fertilizer, mainly human manure and urine. Plant out in May, with a planting spacing of 24×24cm, transplanting two plants per hole, firm the soil by stepping on it, and water thoroughly to help survival.
4. Field management
After transplanting, promptly carry out intertillage and weeding, and do this 3-4 times each year thereafter to promote plant growth. At the same time, combine this with fertilization, as the plants consume large amounts of nutrients during several growth stages. These stages are the new leaf stage, stem elongation stage, bud stage, and seed-setting stage. Apply supplemental ammonium sulfate or human and livestock manure. During the rainy season, pay attention to earthing up to prevent the plants from lodging. After each harvest, apply organic fertilizer as a supplemental dressing.
