| Abstract: | Three fertilizers of N, P and K were applied in clonal seed orchard of Pinus koraiensis young growth and divided into 4 levels in different application rate, respectively. The applied effects by alone or combinations on promoting bearing fruit of the seed trees were studied. This paper offers optimum application rate for promoting fruit production of seed trees at young stage in clonal seed orchard of Pinus koraiensis |
