摘　　要：在昆明大马山树木园开展了促进云南松无性系种子园林木结实措施的研究。经过多因素、多水平、多年度的重复试验,获得了提高其林木种子产量的较佳组合为A2C3B2,即选用生长量高、材质优、结实多的禄丰樟木箐云南松10号无性系为建园材料,在其种子园的经营中每株林木施用浓度为160 mg/L的"云大120"50 mL,以及每株林木施用磷肥+尿素(比例为4?1)的混合肥1 kg,能有效地提高云南松无性系种子园的林木结实量。Multi-factor and multi-level experiments on the measures for promote fruiting of Pinus yunnanensis mother tree in clonal seed orchard were conducted in Kunming arboretum. On the basis of experimental results, the optimum combination was adopting No. 10 clone from Zhangmuqing of Lufeng as materials, applying 50 mL ＇Yunda 120＇ of 160 mg/L and mixed fertilizer of phosphate with urea （4 ： 1 ） , the cone yield of clones grown in seed orchard of Pinus yunnanensis could be effectively increased.
