施肥对红松无性系种子园母树结实效应研究
Fertilizing effect on bearing fruit of seed tree in clonal seed orchard of Pinus koraiensis
【摘要】 通过在红松无性系幼龄种子园进行的氮肥、磷肥和钾肥3种肥料,每种肥料设置4个水平的施肥试验,研究分析了氮肥、磷肥和钾肥3种肥料,以及每种肥料的不同施用数量,对促进红松无性系种子园幼龄母树结实的效果,提出促进红松无性系幼龄植株结实的适宜施肥数量。
【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
