Distribution of Nitrogen,Phosphorus and Potassium Reserves and Allometric Growth in Different Parts of Pinus yunnanensis
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.
