Ginseng is a precious Chinese medicinal material with high medicinal and economic value. Therefore, ginseng cultivation techniques are essential to improve ginseng yield and quality. This article will introduce ginseng planting techniques in detail, including land selection, seed selection, seedling raising, transplanting, field management, etc., in order to provide you with useful ginseng planting technology guidance.
Site selection
The ginseng planting area should choose a flat, well-drained, fertile, unpolluted sandy soil or sandy loam soil. At the same time, it is necessary to pay attention to avoid tuyeres, low-lying land, saline-alkali land and other plots that are not conducive to the growth of ginseng.
Selection
Choosing healthy, pest-free ginseng seeds is key to ensuring ginseng yield and quality. When choosing seeds, you should choose seeds that are full, uniform and bright in color. At the same time, it is necessary to avoid the use of old seeds and irradiated seeds.
Seedlings
1.Germination: Put the purchased seeds in a place with suitable temperature and good ventilation, cover them with moist sand, keep the temperature between 20-25, turn them once a day, and sow them after the seeds germinate.
2.Sowing: sowing after the soil thaws in spring, before sowing, the land should be leveled finely, according to the row spacing of 15-20cm ditch, the depth of the ditch is 2-3cm, the seeds are evenly sprinkled in the ditch according to the amount of 3-5kg per mu, and then covered with soil and lightly compacted.
Transplanting
1.Seedling: Seedlings are raised when the seedlings are 10-15cm, and they should be watered once before the seedlings are raised, and the seedlings should be carefully dug to ensure the integrity of the root system as much as possible.
2.Transplanting: The ginseng seedlings should be planted into the transplanting ditch according to the density of 1500-2000 plants per mu, and the plant spacing should be kept uniform, the root system should be stretched, and the soil should be gently compacted to avoid damage to the root system.
Day-to-day field management
1.Weeding: Weeding should be done in time during the growth of ginseng to avoid weeds competing with plants for nutrients. Be careful when weeding to avoid damaging the plants.
2.Fertilization: Fertilize once in spring and autumn, mainly organic fertilizer, with an appropriate amount of chemical fertilizer. When applying fertilizer, spread evenly around the plant to avoid direct contact with the plant.
3.Watering: Keep the soil moist during the ginseng growth period and water it in a timely manner according to the weather conditions. At the same time, it is necessary to pay attention to drainage and waterlogging to avoid diseases caused by water accumulation in the roots.
4.Pest control: Ginseng is prone to pests and diseases during the growth period, so it should be controlled in time. In the prevention and control, low-toxicity and low-residue pesticides should be selected to avoid affecting the environment and the quality of ginseng. At the same time, attention should be paid to the protection of natural enemy organisms and the use of biological control methods to control the occurrence of pests and diseases.
Harvesting and processing
1.Harvest: Ginseng can be harvested after 3-4 years of growth. Harvest with care to avoid damaging the roots and plants.
2.Processing: The harvested ginseng is cleaned and dried or dried. During the processing process, attention should be paid to maintaining a suitable temperature and good ventilation to avoid mildew or discoloration. Processed ginseng should be stored in a cool, dry place for later use.
In short, ginseng has good economic benefits and high returns when planted properly, but before planting, we must make an analysis according to the market, choose a suitable and reasonable time to enter the game, and master the correct planting technology and management methods in order to obtain high-quality and high-yield ginseng products and increase income for ourselves.
