Cultivation Techniques and Methods for Gymnadenia conopsea (Hand Palm Ginseng)
Gymnadenia conopsea is also called fingered citron ginseng, shou'er ginseng, yin-yang grass, and so on. It gets its name because its shape resembles a palm, has high medicinal value, and is a medicinal herb with high economic value. Today, the editor will introduce to you the cultivation techniques for Gymnadenia conopsea.
1. Land selection and preparation
Gymnadenia conopsea generally grows in alpine grasslands or forest margins. It has relatively strict soil requirements, requiring soil pH between 4.5-5.8. It is best to plant it in sandy loam or loam rich in humus and with convenient drainage and irrigation. Continuous cropping is avoided. It is generally cultivated under forests. If farmland is chosen for planting, the preceding crop should be a grass-family crop. After selecting the land, plow it 1-2 times in the winter of the previous year. After the soil thaws in the following spring, apply 4000 kg of decomposed farmyard manure per mu as base fertilizer during plowing. After shaping and leveling, make beds, and at the same time dig drainage ditches well.
2. Propagation methods
In production, Gymnadenia conopsea is generally propagated by seed. After the seeds mature, harvest them and sow immediately. After overwintering in the soil, the seeds can germinate in the following spring. The seeds can also be stratified in sand to promote germination and then sown in spring, which can also increase the seed germination rate. When sowing, drill in rows on the bed surface at a spacing of 3×5 cm, cover with 2-3 cm of soil, and then cover the bed surface with a layer of rice straw or straw stalks to keep warm and moist, so as to facilitate emergence.
3. Seedling raising and transplanting
After the seeds emerge, do a good job in weeding, loosening the soil, watering, and fertilizing to promote good growth. After 2-3 years of cultivation, they can be transplanted, generally in October-November. If planting in spring, carry it out when the seedlings have not yet sprouted. For transplanting, it is advisable to select strong seedlings with robust root growth and no pests or diseases, and transplant them by grade according to plant size. Before transplanting, they can be properly trimmed and excess fibrous roots cut off, but be careful not to break the root skin. When transplanting, control the plant and row spacing at 8×25 cm or 13×30 cm, arrange the root system well, do not let it twist together, then cover with 4-6 cm of soil, and then cover with straw stalks or rice straw to preserve moisture.
4. Field management
In November, the aboveground stems and leaves of plants that have grown for more than one year will wither. At this time, promptly clean the ground, gather the stems and leaves for deep burial or burning, and at the same time water well for overwintering, and add rice straw or straw stalks to facilitate overwintering. In spring, after the Gymnadenia conopsea seedlings emerge, promptly set up a shed for shade to avoid wilting or death of the seedlings caused by strong light exposure. Before emergence, loosen the soil frequently to avoid soil compaction. When there are too many weeds, weed promptly. When drought occurs, water promptly. After the rainy season, drain promptly. In the year of transplanting, generally no topdressing is needed. After emergence in the second year, promptly remove the covering grass and broadcast one application of decomposed farmyard manure and a small amount of calcium phosphate, and mix evenly with the soil by loosening the soil.
