Abstract
Experiment was conducted on effect of four different N supply levels (0, 50,100 and 175mg/kg) on seedling growth of Lespedeza formosa and N and P content in seedling. The result showed that N supply of 0-100mg/kg could promote seedling height, aerial and underground growth of the seedlings, while treatment with 175mg/kg inhibited seedling growth. When N supply was insufficient, seedlings would allocate much biomass to root system, causing large root crown rate. N content in root, stem and leaf of tested seedling increased with the increase of N supply. When N supply was at 0-50mg/kg, P content in root, stem and leaf increased with the increase of N supply, and when N supply was surpass 100mg/kg, P content decreased.
