How to grow Angelica sinensis seedlings? Detailed tutorial on the latest seedling-raising techniques and methods

Angelica sinensis is a perennial herbaceous plant with extremely high medicinal value and huge market demand, so it attracts many farmers to grow it. However, if you want to obtain high yields, doing a good job in seedling raising is extremely important. So how should Angelica sinensis be raised as seedlings? Let's learn about the relevant knowledge together.

1. Site selection and fertilization

Angelica sinensis seedling raising is suitable on cool, moist semi-mountain slopes with short sunshine duration, weak light, and a good shaded environment, which is suitable for the growth of seedlings. If it is wasteland, first carry out land clearing, remove shrubs and weeds, dry them in the sun and pile them into small heaps to burn into smoked ash, then plow 20-25 cm deep, harrow fine, level, and make beds. Before sowing, apply base fertilizer; generally apply 3000 kg of farmyard manure and 30-40 kg of diammonium phosphate per mu, spread them evenly on the surface, and mix them into the plow layer soil while plowing.

2. Seed selection and sowing

Select seeds from three-year-old plants that are normally mature, well preserved, free of pests and diseases, free of mildew, and with a high germination rate. One day before sowing, dress the seeds with carbendazim and root rot powder. However, late-maturing seeds grow vigorously after sowing, have high sugar content, and are extremely prone to bolting, so old seeds should not be selected. Before sowing, carefully select and remove shriveled seeds. The suitable sowing time is from early May to early June. Generally use 5-6 kg of seed per mu, broadcast on the bed surface, lightly press, and cover with a thin layer of soil so that the seeds and soil are closely connected, which is beneficial for sprouting. After sowing, cover with a layer of rice straw to provide shading and moisture retention, which is beneficial for emergence.

3. Seedbed management

After Angelica sinensis seeds absorb water and swell, they can germinate when the ground temperature is above 10 degrees, and germination is fastest at a ground temperature of 20 degrees. Under suitable conditions, seedlings generally emerge in 7-10 days, and generally full emergence occurs 20 days after sowing. When the seedlings grow to 3 cm and have three leaves, loosen the soil and weed once, and when the third leaf grows, loosen the soil and weed again to promote their growth. During the first loosening and weeding, loosen the seedbed covering material, and during the second loosening and weeding, remove the covering straw to avoid affecting the growth of the seedlings. During the seedling stage, prevent the reproduction of pests and diseases, and apply nitrogen fertilizer in a timely manner to reduce the bolting rate.

4. Lifting seedlings and storage

Lift the seedlings in September-October. When lifting seedlings, pay attention to the seedling root system; damaged roots lead to a low survival rate after transplanting. In addition, when lifting seedlings, carefully screen and remove small seedlings, pest- and disease-damaged seedlings, and mechanically damaged seedlings. After lifting the seedlings, pull off the leaves on the seedlings, tie 100 seedlings into a bundle, place them in a ventilated, cool, and dry place with the seedling heads facing outward, pile them into a cone shape, let them lose part of their water, and reduce their respiration. In November, choose a ventilated, well-drained, cool place, dig a large pit, and stack them with semi-dry raw soil in layers, one layer of seedlings and one layer of soil. When 30 cm from the ground, do not store seedlings further, and fill with soil to form a small mound to avoid water accumulation.
