Planting techniques of Panax ginseng

Palm ginseng, also known as hand ginseng, palm ginseng, fingered citron ginseng, is a rare medicinal material in Qinghai-Tibet Plateau, named because of its similar shape and palm, its medicinal value is high, and its planting quantity in the region is relatively large. So how should palm ginseng be planted? Let's take a look.

1. Land selection and preparation

Palm ginseng generally grows in alpine grassland or forest edge, it has strict requirements for soil, requiring soil pH value between 4.5-5.8, rich in humus, convenient irrigation sandy loam or loam planting is good. Avoid continuous cropping, generally under the forest cultivation, if the choice of farmland planting, cutting crops as gramineous crops. After selecting the land, plough 1-2 times in winter of the first year, combine ploughing after thawing in spring of the next year, apply decomposed farm manure 4000 kg per mu as base fertilizer, shape and rake flat, and dig drainage ditch at the same time.

2. Reproductive methods

The seeds are usually selected for reproduction during production. After the seeds are mature, the seeds are harvested and sown immediately. After the seeds overwinter in the soil, they can emerge in the spring of the next year. The seeds can also be stored in sand for germination treatment and sown again in spring. This can also improve the germination rate of seeds. When sowing, drill sowing is carried out on the ridge surface according to the plant spacing of 3 * 5 cm, soil covering is 2-3 cm, and then a layer of straw or straw is covered on the ridge surface to keep warm and moisture, so as to facilitate seedling emergence.

3. Seedling transplanting

Weeding, loosening, watering and fertilizing should be done well after seed emergence to make it grow well. Transplanting can be carried out after 2-3 years of cultivation, generally in October-11, if it is spring planting, it is carried out before seedling germinates. Transplanting should choose strong seedlings with strong root growth and no diseases and insect pests, transplant them according to the size of the plants, properly shape them before transplanting, cut off excess fibrous roots, but pay attention not to break the root bark. When transplanting, control the row spacing of plants at 8×25 cm or 13×30 cm, arrange the roots, do not twist them together, cover the soil 4-6 cm, and then cover the straw or straw to preserve moisture.

4. Field management

In November, the stems and leaves of plants growing for more than one year will wither. At this time, the ground should be cleared in time, and the stems and leaves should be buried deeply or burned. At the same time, it is better to overwinter water and cover with straw or straw to facilitate overwinter. After spring seedlings emerge, they should be sheltered in time to avoid being exposed to strong light and causing seedlings to wither or die. Before emergence, loosen the soil frequently to avoid soil hardening, weed in time when there are too many weeds, water in time during drought, and drain water in time after rainy season. In the transplanting year generally do not need topdressing, in the second year after emergence to timely remove the cover grass, spread a decomposed farm manure and a small amount of calcium phosphate, through loosening, and soil mix well.

The above is the introduction of palm ginseng planting technology, I hope to help you, want to know more about the relevant knowledge, please pay attention to us.
