摘　　要：为了探索高产脂思茅松人工林的高效培育技术,在普洱市景谷县开展高产脂思茅松扦插苗的造林试验。结果表明:高产脂思茅松扦插苗造林,在定植后具有缓苗期,定植0.5年后开始快速生长;1.5年时,低密度(833株/hm^2)配置模式较高密度(1 250株/hm^2)配置模式生长快,相同密度条件下宽窄行形式的非均匀密度模式较均匀密度模式生长快;定植穴的规格影响植株生长,大定植穴有利于植株的早期生长;施肥对高产脂扦插苗人工幼林的生长具有促进作用;定植穴规格与土壤肥力在幼龄期的互作效应不显著。研究结果可为高产脂思茅松人工林的培育提供参考。Objective to investigate cultivation technology of plantation of high-resin-yield Pinus kesiya var. langbianensis , afforestation experiment of high-resin-yield cutting seedlings was conducted in Jinggu of Pu＇ er city of Yunnan Province. The results showed that： There was a recovery period for cutting seedlings of high-resin- yield after plating, the growth rate of seedling began to faster when the age was 0. 5 year. The Low density （833plants/hm^2） mode had higher growth speed of seedling than higher density （1 250plants/hm^2） mode at the age of 1.5 year, and the wide/narrow row alternation mode had higher growth speed than even row spacing mode in the same density. The planting hole with large size had well growth than little size. Fertilizer could promote the early growth of high-resin-yield plantation of cutting seedlings. The difference was not significant in hole size -soil fertility interaction. The results could provide reference for cultivation of plantation of P. kesiya var. langbianensis with high-resin-yield.
