Phosphorus fertilization with Cleyera japonica seedlings
Based on a pot experiment,the effects of phosphorus fertilization on growth and physiological indexes and phosphorus content in leaves of one-year-old Cleyera japonica seedlings were studied. Seven P(P2O5) levels were set,0(ck),0.125,0.250,0.375,0.500,0.625 and 0.750 gpot-1. Results showed that (1) with increasing levels of P from 0 to 0.500 gpot-1,growth and physiological indexes in C. japonica seedlings increased,whereas with P increases over 0.500 gpot-1,all indexes decreased. Also,(2) P in leaves increased with increasing levels of P from 0 to 0.500 gpot-1 but decreased gradually with further P. Finally,(3) quadric relationships between growth indexes and P were noted. Based on growth and physiological indexes for one-year-old C. japonica seedlings,proper application of P was from 0.441 to 0.603 gpot-1.[Ch,2 fig. 5 tab. 11 ref.]
