To propagate Astragalus membranaceus with seeds, you can refer to the following methods:
1. Properly treat hard seeds. Be sure to pay attention to this point when growing Astragalus membranaceus for the first time. For hard seed conditions, use a roller mill until the seed coat is scratched without damaging the kernel, otherwise seedling emergence will be seriously affected.
2. Choose a suitable sowing period. Sowing can be done in spring, summer, and autumn, generally in June-July when the rainy season arrives. At this time, soil moisture is sufficient and the temperature is high, so seedlings can emerge about 7 days after sowing; high soil moisture is also good for preserving seedlings. Spring sowing lacks water, and seedlings often suffer drought. Sowing near winter results in a low emergence rate.
3. Use a suitable sowing method. Hole sowing is mainly used. Because hole sowing preserves soil moisture well, covers soil evenly, and firms the soil moderately, it is good for seed germination and seedling emergence. For hole sowing, dig holes at a spacing of 20-25 cm, sow 3-10 seeds per hole, cover with 1.5 cm of soil and press flat, with a sowing rate of 1 kg per mu.
4. Raise seedlings and transplant. For seedling raising, broadcast sowing or drilling can be used. For drilling, the row spacing is 15-20 cm, and the seed rate is about 2 kg per mu. After Astragalus membranaceus seedlings grow for 1 year, transplant them in late autumn or early spring. Transplant immediately after lifting the seedlings. When transplanting, open furrows at a row spacing of 40-50 cm, with a furrow depth of 10-15 cm. Place the roots upright in the furrows at a plant spacing of 15-20 cm, then cover with soil and water.
