摘要
为更好进行云南松苗木培育,提升云南松苗木质量,通过对2年生云南松苗木生长性状及不同部位氮(N)、磷(P)、钾(K)储量进行统计以及相关性、异速生长分析,研究云南松氮、磷、钾储量。结果表明,云南松幼苗生长2年后,其地下部位氮、磷、钾分配大小依次为钾储量>氮储量>磷储量;氮、磷、钾在土壤中的分配比例为氮储量>磷储量>钾储量;地上部位氮、磷、钾储量占单株氮、磷、钾储量的比例为钾储量>磷储量>氮储量;磷和钾在地下部位的累积速率大于地上部位的累积速率。以期为云南松苗木培育提供理论参考,为实际生产提供一定理论依据。
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 analysis and allometric analysis.The results showed that the distribution of N,P and K in the underground 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 accumulation rate of P and K in underground parts was faster than that in aboveground parts.The research results aim to provide theoretical reference for the cultivation of P.yunnanensis seedlings and provide a certain theoretical basis for actual production.
