The high-yield planting techniques of American ginseng, the king of all kinds of grass, are explained in detail.

American ginseng, also known as Guangdong ginseng and American ginseng, is native to the northern United States and southern Canada. It can be boiled, stewed, steamed, sliced or ground into fine powder. Here is a detailed description of the high-yield planting techniques of American ginseng, the king of all grasses.

I. selection of sites

Because it likes the cool and humic climate of semi-overcast and half-yang and the fertile soil rich in humus, American ginseng planting land should be selected on the southwest-northeast ventilation duct with good drainage and fertile land on both sides of the river, rather than in the open and dry zone in front of the mountain and the winter cold wind tunnel moving towards northwest and southeast. practice has proved that as long as the scientific application of organic fertilizer, rational use of chemical fertilizer. It is feasible in sandy loam and silty loam which are relatively rich in phosphorus and potassium.

II. Land preparation

In order to reduce the harm of nematodes and other diseases and pests, Gramineae should be used in the first crop of American ginseng, such as wheat and corn after harvest, turning ridges once a month to promote the decomposition of the residues of the previous stubble and accelerate soil ripening. At the same time, crushing fine and high quality organic fertilizers such as 6000kg mature pig manure and cattle and horse manure (chicken manure and human manure are not alkaline) and rotten cake fertilizer 50kg and high quality ternary compound fertilizer 100kg are evenly mixed into 2030cm plough layer.

In late autumn, a high border is built every 2m, the height of the border is 25cm, the top of the border is 1.4m, the ratio of side to slope is 1 ∶ 1, the width of the bottom of the ditch is 10cm, and the surface of the border is as thin as possible, and it is covered with fine crushed phosphate-containing wind fossil 3cm (4cm of seedlings), and then covered with 1-2cm after sowing. In the middle, it is necessary to disinfect the soil with 50% carbendazim per square meter, of which 15g is ploughed and mixed into the soil. When sowing, the remaining 5g was mixed into the phosphorous wind fossils covered by the upper bed of the border.

Third, sowing seeds

1. Seed treatment

When the ginseng fruit is red in August, you can immediately scrub the pulp and wash it and dry it a little. Soak the seeds with 1000 times 50% carbendazim for 10 minutes, then soak them with 50ppm gibberellin for 24 hours, then fish out and rinse with clean water for 1 time and then mix with sand (∶ sand = 1 ∶ 3). After sand mixing, put it in a cool place until November, the temperature should be controlled below 25 ℃, and the humidity should be 12% with 10% water. If the seeds are too wet and perishable, they will be loosened as soon as they are loosened in a mass. The seeds are flourishing in that year and weak in the next year.

two。 Sowing time

In late November, 80% of the cracks could be treated by the above method, and about 30% of the cracks not treated with gibberellin could be picked out and sown in batches. The sowing date was until the end of December, and the remaining unexploded cracks were placed under 0 ℃, and they could still burst in February of the following year, and seedlings could also emerge after sowing. Those who burst later could not emerge because the low temperature treatment time was not enough for 70 days, and physiological post-ripening could not be completed, or incomplete.

3. Sowing method

Sprinkle 3cm on the surface of the leveled soil moisture border, sift the moist wind fossils evenly, and then sow the seeds with the standard 5 × 6cm row spacing punching plate (deep 2cm) to keep the depth standard consistent, and then sprinkle the sterilized wind fossils cover seeds after sowing. In order to flatten the fossils, cover the fossils with a plate to ensure the sowing depth of 2cm, and then cover with 10-15cm thick grass to preserve moisture and prevent freezing.

The above is the introduction of Tuliu.com on the high-yield planting technology of American ginseng. If friends who want to start planting should consider in advance whether the conditions are satisfied, planting medicinal materials and crops are different, the rigid requirements are very high, and the cost is also high. So a series of problems should be considered in order to ensure profitability.
