思茅松整地方式与初植密度试验初报

摘要

Cultivation experiment with two different methods of soil preparation ( hole,strip) and four different initial planting density (5000,2500,3334,1667 strains of hm -2 ) a total of eight kinds of cultivation model tests.Tests to be carried out after half a year ,at the end of each year the young tree height and DHB were investigated ,for 5 years,through the variance analysis of the survey results showed that strip soil preparation .planting density is 1667 strain of hm -2 showed the best cultivation mode .%在云南省景谷县高产脂思茅松研究基地，开展了思茅松用材林2种整地方式（穴状、带状）及4种初植密度（5000、2500、3334、1667株· hm-2）栽培试验。通过连续5 a对树高和胸径的调查及结果分析表明，以带状整地、初植密度1667株· hm-2的栽培模式最有利于思茅松用材林幼林的生长。
