【Objective】The dynamic characteristics and the correlations among ten elements N,P2O5,K2O,Ca,Mg,Cu,Zn,Fe,Mn and B in mature Jatropha curcas leaves were studied in order to provide theoretic references for appropriate fertilization in Jatropha curcas. 【Method】Jatropha curcas trees in the same growth status were fertilized per strain with0,0.2,0.4 and 0.6 kg compound fertilizer. Samples were collected every 30 days to determine the nutrient element content in mature leaves and analyze the dynamic characterist...
