RESUMEN
OBJECTIVE: To study the growth of Glycyrrhiza uralensis under different planting density for providing theoretic evidence for reasonable planting density. METHOD: The field experiment was designed by single factor randomized block. RESULT: The plant height, root diameter, main root length and branches of main stem were all decreased with increasing planting density of G. uralensis. Meanwhile, dry matter accumulation on root, leaf, aerial part and rhizome were all decreased with increasing planting density. CONCLUSION: Two hundred and seventy thousand plants/hm2 was feasible planting density.
