Astragalus, also known as Yuanqi or Beigi, is a perennial deep-rooted herbaceous plant of the legume family. Its root is used medicinally and has functions such as tonifying qi, strengthening the exterior, and promoting pus discharge and tissue regeneration. Astragalus is highly adaptable and can be grown in ordinary soil. It is drought-tolerant and cold-tolerant, and deep, loose sandy soil is most suitable. The key points of its cultivation techniques are as follows:
1. Sowing
The planting method: sowing can be done in spring, summer, or autumn. Before sowing, soak the seeds in warm water for 6 hours, then remove the seeds and place them in a basin before sowing. Choose sandy soil with good drainage and strong water permeability, apply sufficient base fertilizer, plow and harrow finely, and make wide beds. After watering for 3-5 days, level the bed surface with an iron rake, open furrows 1-2 cm deep at a row spacing of 23-27 cm, scatter the seeds into the furrows, and push over them once with a large hoe. Then level and refine the bed surface. Seedlings emerge in 6-7 days.
2. Field management
Before emergence, keep the soil moist. After emergence, water less and loosen the soil more to encourage the roots to grow downward. When the seedlings are 6-7 cm tall, thin them to a plant spacing of 10-13 cm. When they are 17-20 cm tall, apply topdressing: 10-15 kg of chemical fertilizer and 25-40 kg of fermented cake fertilizer per mu. When they are about to bloom, water demand gradually increases, so the frequency of watering can be appropriately increased. Generally there are no pests or diseases. If there is excessive rain, pay attention to drainage.
3. Harvesting and processing
In the autumn of the same year or the autumn of the following year, dig and harvest when the aboveground stems and leaves wither. Shake off the soil, remove the reed stems, dry in the sun, and tie into small bundles for sale. Generally, the yield per mu in the same year is about 300 kg of dried product and 900-1,100 kg of fresh product.
