Effects of Fertilization on Seedlings of Rare and Endangered Species Erythrophleum fordii

Biogas liquid manure( BLM),compound fertilizer( CP),algae oil( AO),peanut bran liquid manure( PBLM),and tung bran liquid manure( TBLM) were applied in container seedlings of Erythrophleum fordii. The results showed that fertilization types and fertilization levels had significant impacts on seedling height,ground diameter,rhizobia number and biomass,but not on growth of lateral roots. Seedling height growth and biomass accumulation in treatment 3( CP ∶ AO ∶ BLM was 0. 45% ∶0. 1% ∶ 20. 0%) showed the best. Treatment 4( CP∶ AO∶ BLM was0. 6% ∶ 0. 1% ∶ 15. 0%) had the highest ground diameter growth. Treatment 2( CP∶ AO∶ BLM was 0. 3% ∶ 0. 1% ∶ 25. 0%) had the most lateral roots,and Treatment 16( 2. 0% TBLM) formed the most rhizobia. Based on comprehensive evaluation of seedlings,treatment 3,4,7( 32. 5% BLM),12( 2. 0% PBLB),and 15( 1. 5% TBLM) had better effects on growth of the seedlings,especially treatment 3.
