The Latest High-Yield Planting Techniques and Methods Tutorial for American Ginseng

American ginseng is a traditional Chinese medicine of the ginseng type with very high medicinal value. It is also called flower flag ginseng, and it and flower flag ginseng are the same plant, just with different names. American ginseng originated in Canada, and now American ginseng has a very wide range of uses in all aspects. It can be stewed into soup and can also be boiled into traditional Chinese medicine, attracting a large number of investors to participate in planting. So how should American ginseng be planted to achieve high yield? Shuai Shuai will explain it to everyone below!

1. Site selection

First, choose a good planting site. American ginseng needs to be planted in slightly acidic humus soil, and there should preferably be irrigation resources around the land. For example, in China, mountain broad-leaved forest areas at an altitude of 800-1100 m or fertile garden fields are all good places for planting, and the soil is also very fertile acidic soil.

2. Land preparation

After choosing the planting land, deep plowing should be carried out in the spring and summer of the year before planting, then it should be left there. After exposure to the sun, spray it with carbendazim, then disinfect the soil, then add decomposed manure and bone meal, mix the soil evenly, and plow the land well so that it is more conducive to drainage and air flow.

3. Transplanting

After the ginseng seedlings are cultivated for two years, carry out spring planting. Use the slanted planting method and cultivate according to grade as large, medium, and small. When planting, keep the ground at a slant angle of 40 degrees to 45 degrees with the planting furrow. Spread some bone meal in the furrow. The soil covering thickness should be about 5 cm. Some leaves can be placed over the bed, which can play a role in heat preservation and help the seedlings pass through winter smoothly.

4. Seed treatment

The seed embryo is of the after-ripening type, and the seeds will enter a long dormant period, so the seeds must be treated in advance to allow physiological after-ripening. First clean the seeds, then store them with fine sand, then keep a little humidity so that they have a self-supply of moisture, then place them in a basement for storage and let them mature on their own. After complete after-ripening, treat them at a low temperature of 0-5 degrees. After four months, they can germinate. Once the germination rate reaches 85%, they can be sown.

5. Field management

American ginseng is a shade plant, so it cannot be exposed to direct sunlight. A shade shed should be set up above it, and the light transmittance only needs to be 25%-36%. Then fertilization should mainly be decomposed fertilizer, bone meal, and compound fertilizer. During the growing period, fertilizer should be applied frequently. In summer, covering should be carried out to avoid direct sunlight. Water irrigation is also one aspect, and the soil moisture content should be kept at about 40%.

6. Pest and disease control

1. Damping-off

This disease is mostly caused by poor soil permeability and soil compaction. It can be treated by spraying with zineb solution.

2. Leaf spot disease

Leaf spot disease is also called black spot disease. It mainly harms the leaves of American ginseng, and sometimes also infects its flowers and other parts. Bordeaux mixture, zineb solution, and polyoxin can be used for spraying. The field should be disinfected more often, and seeds should be disinfected when selected. When selecting seeds, the seeds can be soaked in formalin, which can greatly prevent leaf spot disease.

3. Leaf rust

This is a disease that makes leaves turn yellow and wither. In severe cases, it spreads directly to the entire leaf and causes direct death. The control method is the same as for black spot disease.

4. Rust rot

Rust rot is a disease that occurs at any stage of the plant, and it is also one of the diseases with the highest frequency and relatively great impact on American ginseng. It can cause the underground stem to rot and produce yellow-brown rust-like disease spots. After rotting, seedlings can no longer emerge, so the impact is very great. It can be addressed starting from the soil. The soil must be fully decomposed, and it must have good drainage and ventilation. Maintaining soil looseness is very important. When transplanting, ensure the health of the plants. Antimycin can be used to soak the roots, and the soil should be disinfected more to prevent the invasion and breeding of pathogens.

The above are the high-yield planting techniques for American ginseng. Has everyone learned them? Friends who want to start planting should consider in advance whether the conditions are met. Planting medicinal materials is different from planting crops and other crops. The hard requirements are very high, and the cost is also high, so a series of issues must be considered in order to ensure profitability. The above planting techniques were summarized and written by the editor, and are for everyone's reference only. I hope they can help everyone.
