对2年生云南松实生苗统一截顶后，采用 L9（34）正交设计进行施肥、喷施 B-Y2和 IBA 溶液的试验，分析不同组合对穗条产量等的影响。结果表明：试验进行90 d 时，平均萌芽数和新枝数为13.2～18.7芽／株和4.4～9.7枝／株。180 d 时，不同组合的平均单株穗条产量和枝条成穗率为2.6～5.9条／株和13.9％～52.2％，影响2项指标的主导因子是 B-Y2，其理论优水平组合为每株施有机肥0.05 kg 和喷施4.0×107 CFU ／mL 的 B-Y2溶液。有机肥可促进萌芽和穗条产量的提高；IBA 促进萌芽和枝条的生长，但抑制萌芽形成枝条；B-Y2可提高穗条的产量。培育地径粗壮的无蹲苗的壮苗是提高云南松穗条产量的关键；同时，2年生的苗木，在养分充分满足其生长的前提下，喷施4.0×107 CFU ／mL 的 B-Y2溶液也可增加穗条产量。

after unified cut apical buds for 2-year-old Pinus yunnanensis seedlings,the L9 (34 )orthogonal de-sign was applied to implement the experiment of fertilization,praying B-Y2 and IBA solution on needles,which purpose was to detect the effects of factors and their levels with treatment combinations (TC)on cutting yield,etc. Mean numbers of sprouting buds and new branches were 13.2 -18.7 bud /plant and 4.4 -9.7 branch /plant,re-spectively,when the experiment was carried out for 90 days.After 180 days,mean cutting outputs and the ratios of cutting/branch between the TCs were 2.6 -5.9 cutting/plant and 13.% -52.2%,respectively,which main fac-tor of influencing these two parameters was B-Y2,with the optimal theoretical TC of fertilizing organic fertilizer for 0.05 kg/plant and spraying B-Y2 solution on the needles for the 4.0 ×107 CFU /mL.Organic fertilizer facilitated sprouting buds and increased the cutting yield;the IBA improved sprouting buds and branch growth,while which limited the buds to form the branches;and B-Y2 could increased cutting yield.Sound seedlings of presenting large basal diameters with non grass stage are the pivotal element of increasing cutting output of P.yunnanensis;simulta-neously,based on the condition of sufficient growth nutrients for 2-year-old seedlings,spraying 4.0 ×107 CFU /mL of the B-Y2 solution on the needle could be facilitated cutting yield as well.
