Where to buy Golden Thread Orchid seeds? Latest buying channels summary
Golden Thread Orchid, also known as Golden Thread Orchid (Anoectochilus), Bird Ginseng, and Golden Coin Grass, is a perennial herb of the genus Anoectochilus in the orchid family. The whole plant can be used as medicine. Folk legend holds that it has the effect of treating all diseases, and it has long been known as the “King of Medicines.” It is very rare in number. At present, greenhouse cultivation or simulated wild cultivation already exists. Now let us take a look together at where Golden Thread Orchid seeds are sold!
Where are Golden Thread Orchid seeds sold?
Golden Thread Orchid seeds are sold at some medicinal herb planting bases, but what is generally sold on the market are Golden Thread Orchid seedlings, at about 0.3 to 0.5 yuan per plant. Before cell tissue culture, Golden Thread Orchid relied solely on natural seed germination, but the seeds are extremely fine, and each seed contains only one incompletely developed embryo, so germination power is very low. In addition, the seed coat does not readily absorb water, and sowing by conventional methods cannot produce germination. Therefore, orchid mycorrhizal fungi or artificial culture media are needed to supply nutrients for germination. From sowing to transplanting takes half a year to one year. Therefore, in current production, Golden Thread Orchid is mostly propagated by cell tissue culture.
Growing conditions for Golden Thread Orchid
1. Temperature: Golden Thread Orchid has strong adaptability to temperature. The suitable temperature for growth is 20 to 32 degrees C. Under greenhouse cover, a continuous 30 days of low temperature of 0 to 5 degrees C still causes no obvious damage to Golden Thread Orchid, while 15 days of daily temperatures above 34 degrees C easily causes leaf curling and damage to quality.
2. Moisture: Golden Thread Orchid is naturally distributed in forest environments with high humidity and near some streams. Moisture is the most important factor affecting the survival of Golden Thread Orchid, but it can survive in environments with dry climate and water-deficient soil. For artificial cultivation, the relative humidity should be above 70%.
3. Light: Golden Thread Orchid is a shade-loving plant. Its light saturation point for photosynthesis is low, and the suitable light intensity is about 3000 lux. Under natural conditions, the canopy density of the upper tree layer is 7% to 80%, and the coverage of the lower vegetation layer is about 40%.
4. Soil: Golden Thread Orchid is suitable for rooting under slightly acidic soil conditions. The soil should be loose, breathable, and moist. Under natural conditions, it is distributed in humus soil, yellow soil, and red soil types. For small-scale planting, peat soil and perlite are recommended.
Planting methods for Golden Thread Orchid
1. Variety selection: At present, the widely cultivated Golden Thread Orchid varieties include the Fujian variety and the Taiwan, China variety, both of which have good adaptability and are liked by consumers. In particular, wild Golden Thread Orchid from Liangye Mountain and Guanzhai Mountain is very popular after artificial cultivation, while the Taiwan, China variety is relatively sensitive to low temperatures.
2. Seedling method: For large-scale cultivation of Golden Thread Orchid, tissue-cultured seedlings should be used. Tissue-cultured seedlings can maintain the excellent traits of the mother plant and are uniform. It is required to select tissue-cultured seedlings that have been hardened in a shed for more than 15 to 30 days, with a seedling height above 6 cm and 2 to 3 leaves, for transplanting.
3. Reasonable dense planting: Golden Thread Orchid is planted at a spacing of 2×5 cm, with 140 to 150 plants transplanted per tray. The seedlings are washed clean with clear water. When planting, the depth should be controlled at about 1 cm. Deep planting is avoided. After planting, spray with a 800 to 1000 times dilution of 45% metalaxyl-hymexazol wettable powder.
4. Post-planting management: One week after transplanting Golden Thread Orchid, spray once every 7 days with a 500 times dilution of 10% amino acids. Within 15 days after transplanting, use film covering, and control the temperature inside the shed between 20 and 27 degrees C, the relative air humidity at 70% to 80%, and the substrate humidity at 70% to 75%.
5. Harvesting and processing: Golden Thread Orchid can be harvested when it is more than 10 to 15 cm tall, has 5 to 6 leaves, leaf width 2 to 2.5 cm, leaf length 3 to 3.5 cm, the leaf underside is purplish red, the golden vein network on the leaf surface is obvious, and the stem is green. When harvesting, shake off the soil, wash clean, and sun-dry or oven-dry.
6. Pest and disease control: Install insect-proof nets around the Golden Thread Orchid planting shed, use sugar-vinegar liquid to trap and kill black cutworms, or use biological pesticides such as bacteria, fungi, viruses, plant extracts, and antibiotics to kill pests and diseases. For chemical control, choose highly effective, low-toxicity, low-residue pesticides.
