Jaundice breeding method
1. Site Preparation and Soil Preparation: Choose a fertile, well-drained sandy loam or alluvial soil for optimal growth. Avoid areas with poor soil quality, high clay content, or excessive moisture, as these conditions can hinder plant development. It's essential to enrich the soil with organic fertilizer and ensure deep tilling to improve aeration and root penetration.
2. Seed Propagation: (1) For hard-coated seeds, especially when cultivating for the first time, it is crucial to scarify them properly. Use a roller to gently break the seed coat without damaging the kernel inside, as improper treatment can significantly reduce germination rates. (2) Sowing can be done in spring, summer, or autumn, but the best time is during the rainy season, typically between June and July. At this time, the soil is moist and warm, which promotes quick germination—usually within 7 days. In spring, water availability may be limited, leading to dry conditions that can harm young seedlings. Winter sowing often results in lower emergence rates. (3) Direct sowing is commonly used. Ensure even coverage of soil and moderate pressure to promote uniform germination. For hole sowing, dig holes spaced 20-25 cm apart, place 3-10 seeds per hole, cover with 1.5 cm of soil, and use approximately 1 kg of seeds per mu. (4) Transplanting seedlings is also an effective method. Seedlings can be sown or drilled, with spacing of 15-20 cm between plants, using around 2 kg of seedlings per mu. After one year of growth, Astragalus membranaceus is usually transplanted at the end of autumn or early spring. When transplanting, dig trenches 40-50 cm apart, with a depth of 10-15 cm. Place the roots in the trench, space the plants 15-20 cm apart, cover with soil, and water thoroughly after planting. This approach helps establish strong, healthy plants for long-term growth.
