摘要
油松幼苗采用单株、双株两栽植点、3株丛植3种不同穴植方式进行栽植,运用标准地调查法,调查并分析了其造林成活率与投入成本。研究结果表明:油松穴植的成活率主要与栽植技术和造林地有关,单株、双株两栽植点、3株丛植成活率都达到95%以上,三者基本没有差异。从造林成本来看,单株费用最少,效果较好。建议在今后大面积造林中,大力提倡每穴单株造林。
The planting of Chinese pine was made by 3 planting treats involving single-seedling hole, doubleseedling hole and three-seedling hole. Sample plot investigation method was used to investigate and analyze survival rate and cost of Chinese pine afforestation. The results indicate： The survival rate is mainly related to planting technology and afforestation site. The three planting methods have no difference at survival rate （more than 95%） single-seedling hole planting is the least on the cost and had better effect. So it is suggested that the single seedling hole planting at afforestation should be popularized at large scale in the future.
