How to plant the latest angelica seeds?

Angelica belongs to the umbrella family and belongs to perennial herbs. it is suitable for cold and cool climate. it can be cultivated at an altitude of about 1500-3000 meters above sea level, and the rate of bolting is high in low-sea areas, which is not easy to oversummer. It is suitable for the cultivation of sandy loam soil rich in humus, which is deep, loose, well drained and rich in humus. It is not suitable to grow in low-lying stagnant water or easily consolidated clay and barren sandy soil. Let's take a look at how Angelica seeds are planted.

Seed selection and soil preparation

Angelica sinensis seeds are usually collected in the second year after transplanting, which can be harvested when the seed coat is blue or pink, and then threshed and stored after air-drying. Angelica seedlings should choose leeward, shady slopes or wasteland. Turn the ground in late May, use the burned weed ash as base fertilizer, turn it into the soil, and then rake flat to make a high bed, 1.2 meters wide. Before sowing, apply base fertilizer, 2500-3000 kg per mu, turn it into the soil, fine and flat.

Sowing and raising seedlings

Angelica seeds are suitable for sowing from early to late June, open horizontal ditches according to the distance of 17cm to 20cm, evenly sow the seeds, cover a layer of fine soil, cover the seeds strictly, and then cover a layer of weeds. Sow seeds 4 kilograms per mu. The suitable temperature for germination is about 20 ℃, and the seedlings emerge about half a month after sowing. At this time, the cover grass will be loosened to prevent the seedlings from being hurt when the grass is uncovered. Uncover the grass at the beginning of August. Weeds should be removed to keep weeds free in the field. Combined with weeding seedlings, it is appropriate to remove the weak and stay strong, and the distance between plants should be about 1 cm.

Seedling storage

Angelica sinensis seedlings should be stored in early October, the seedlings should be dug up by the roots, tied into small handfuls, and stored in piles or cellar. If you want to store it, choose a cool house that does not make a fire, and pile up a layer of loess in the house. Outdoor cellar, choose a cool and dry place. Excavation cellar depth, width of 1 meter, long depending on the number of plants, with a layer of planting a layer of loess heap, cellar top cover of about 30 cm of soil, high above the ground.

Seedling transplanting

The seedlings of Angelica sinensis should be transplanted in the early and middle of April, and the seedlings should be planted in a triangle with a distance of 35 × 25 cm and a hole depth of 16 cm on the finished border. It is better to choose the root diameter of the seedlings to be controlled at about 3.5 mm. If the root is too large, it is easy to bolt in advance, and if it is too small, the adaptability is poor and the survival rate is low. After planting, cover the soil while pressing, and then cover the soil without passing the root neck of the seedling by 2 to 3 centimeters.
