American ginseng is the most important plant in the world.

American ginseng is a kind of ginseng traditional Chinese medicine with very high medicinal value, which is also called American ginseng. It is the same plant as American ginseng, but its name is different. American ginseng originated from Canada, and now American ginseng has a wide range of uses in all aspects. It can be stewed and made into traditional Chinese medicine, attracting a large number of investors to participate in planting, so how can American ginseng be planted with high yield? Next Shuai Shuai will tell you about it!

I. selection of sites

First of all, it is necessary to choose a good planting site. American ginseng needs to be planted in slightly acidic humus soil, and it is best to have irrigation resources around the land. for example, in China's mountain broad-leaved forest belt with an altitude of 800-1100 meters or fertile garden fields are good places for planting, and the soil is also very fertile acidic soil.

II. Land preparation

After selecting the land for planting, you should carry out deep ploughing in the spring and summer of the year before planting, then leave it there, then spray it with carbendazim after exposure, then disinfect the soil, and then add rotten barnyard manure and bone meal to mix the soil evenly, ploughing the land well, so that it is more conducive to drainage and air flow.

3. Transplanting

After two years of cultivation, the ginseng seedlings were planted in spring, and the oblique planting method was used to cultivate them according to large, medium, small and medium-sized grades. When planting, keep the ground and the planting ditch at an oblique angle of 40 to 45 degrees, and sprinkle some bone powder in the ditch. The thickness of the covered soil is about 5 cm. Some leaves can be covered on the border, which can play a heat preservation role and help the seedlings survive the winter smoothly.

IV. Seed treatment

The seed belongs to the type of embryo after ripening, and the seed will enter a long dormant period, so the seed should be treated in advance to allow it to mature physiologically, clean the seed first, then store it with fine sand, and then keep a little bit of humidity to make it self-supplying water. then it is stored in the basement to allow it to mature, and after complete ripening, it should be treated at a low temperature of 0-5 degrees, and it can germinate in the first four months. It can be sown after the germination rate reaches 85%.

V. Field management

American ginseng is a shady plant, so it can not be exposed to direct sunlight, so it is necessary to assume a shade shed above it, with a transmittance of only 25%, 36%, and then fertilize mainly rotten fertilizer, bone powder and compound fertilizer, often topdressing during the growing period, summer mulching to avoid direct sunlight, and water irrigation on the one hand, to keep the soil water content at about 40%.

VI. Pest control

1. Blight

The disease is caused by poor soil permeability and soil consolidation, which can be treated with Dysen zinc solution.

2. Spot disease

Spot disease, also known as black spot, mainly harms the leaves of Panax quinquefolium, and sometimes infects its flowers and other parts. Bordeaux solution, Dysen zinc solution and polyantimycin can be used for spraying, disinfection in the field and disinfection when selecting seeds. Seeds can be soaked in formalin during seed selection, which can greatly prevent spot disease.

3. Leaf rust

This is a disease that yellowes leaves and dies. In serious cases, it spreads directly to the whole leaf and dies directly. The control method is the same as that of black spot.

4. Rust rot

Rust rot is a disease that occurs at any period of the plant, and it is also a disease with the highest frequency of influence on American ginseng. It can cause the underground stem to rot and produce yellowish-brown rust spots, so it can not emerge after decay, so it has a great impact. It can start from the soil, the soil should be fully mature, and it is important to maintain the looseness of the soil. To ensure the health of the plant during transplanting, antimycin can be used to soak the roots and disinfect the soil to prevent the invasion and breeding of bacteria.

These are the high-yield planting techniques of American ginseng. Have you learned it? If you want to start planting friends should consider in advance whether the conditions are met, planting medicinal herbs and crops and other crops are different, the rigid requirements are very high, and the cost is also high, so a series of problems should be taken into account, so as to ensure profitability. The above planting techniques are summarized and compiled by the editor, only for your reference. I hope to help you.
