The Latest Planting Techniques and Methods Tutorial for Goldenrod
Goldenrod is a perennial herb of the Asteraceae family and 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 flavonoid components and has excellent anti-cancer effects. Due to its high medicinal value, people harvest it excessively, and wild plants are increasingly decreasing. At present, it is a rare plant, and it is cultivated in many areas. So how should goldenrod be planted? Let's take a look together.
1. Land selection and land preparation
Goldenrod prefers a cool and humid climate and is cold-resistant. It is suitable to plant it 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 land, plow it repeatedly so that the soil naturally weathers, remove weeds, and apply decomposed farmyard manure as base fertilizer according to the soil fertility status. After mixing it evenly with the soil, make beds and then ridges, dig drainage ditches well, and wait for planting.
2. Propagation methods
Goldenrod can be propagated by seeds and division, but in production the seed propagation method is generally used. In November-December, cut off the mature fruiting branches, place them in a cool place to dry naturally, 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, preferably just covering the seeds, press gently with your hands, then water, cover with grass to preserve moisture, and it is done.
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 topdress fertilizer, mainly with human feces and urine. Plant out in May, with a planting spacing of 24×24cm, transplant two plants per hole, cover with soil and firm it, and water thoroughly to settle the roots so as to promote survival.
4. Field management
After transplanting, promptly carry out intertillage and weeding, and thereafter carry out 3-4 times each year to promote plant growth. At the same time, combine this with fertilization. The plants need to consume a large amount of nutrients during several growth periods. These stages are respectively the new leaf stage, stem elongation stage, bud stage, and seed-setting stage. Topdress with ammonium sulfate or human and livestock manure. During the rainy season, pay attention to hilling soil to prevent the plants from lodging. After each harvest, topdress with organic fertilizer.
