In order to better cultivate Pinus yunnanensis seedlings and improve the quality of P.yunnanensis,seedlings,the growth characters and reserves of nitrogen(N),phosphorus(P)and potassium(K)in different parts of 2-year-old P.yunnanensis seedlings were studied by descriptive statistics,correlation a-nalysis and allometric analysis.The results showed that the distribution of N,P and K in the under-ground parts of 2-year-old P.yunnanensis seedlings was K>N>P;the proportion distribution of reserves in soil was N>P>K;the proportion of aboveground parts to reserves per plant was K>P>N;the accu-mulation rate of P and K in underground parts was faster than that in aboveground parts.The research re-sults aim to provide theoretical reference for the cultivation of P.yunnanensis seedlings and provide a cer-tain theoretical basis for actual production.
