Abstract: To develop a good understanding of growth-development of transplanted Astragalus membranaceus, and an accurate division of phenological phases, A. membranaceus sleedings were studied by classification transplanting. Fixed-point and real-time observations were combined with comprehensive surveys in the field, to observe and compare the growth and development stages of different grade seedlings of A. membranaceus. The phenological phases of A. membranaceus were divided into five stages: emergence after transplantation, budding and flowering stage, elongation stage of roots, fruit maturation stage, and diameter of roots.
