摘　　要：以4种整地方式下杂种落叶松试验林为研究对象,建立固定观测样地48块,连续观测地径、苗高和胸径生长,采用方差分析等研究方法,研究整地方式对杂种落叶松生长的影响,结果表明:杂种落叶松幼龄期间的地径及苗高生长,高台和穴状两种整地方式较好,另外两种整地方式差些;揭草皮方式在杂种落叶松幼龄时对其苗高生长及地径的作用不明显,但随着幼树的生长,效果越来越显著;在杂种落叶松11龄时,穴状与揭草皮两种整地方式下的平均胸径较大;杂种落叶松4种整地方式对生长的作用效果穴状>揭草皮>高台>现整现造。Based on 4 soil preparation patterns for crossbreed larch experiment forests, 48 permanent plots were established. Diameter on the ground, height of seedling and growth of DBH were continuously observed. By variance analysis method, influence of soil preparation pattern on the growth of crossbreed larch was studied. Results soil preparation patterns of were worse. The influence showed that for the growth of diameter on the ground and height of seedling, high platform and cave were better at young age, and the other two patterns of exposing sod on the growth of diameter on the ground and height of seedling of crossbreed larch was not obvious. But with the growth of young trees, the influence was getting more and more obvious. At age of 11 years, the mean DBH of crossbreed larch was bigger for high platform and cave patterns of soil preparation. The order of influence of 4 soil preparation patterns on the growth of crossbreed larch was cave 〉 exposing sod 〉 high platform 〉 preparing while planting.
