用３种不同高度、４种不同根茎比的苗木，分别栽入苗木根茎总长的９０％、８０％、７０％、６０％、５０％进行造林对比试验，认为在干旱裸露沙丘的阳坡上，樟子松造林以深栽少露为好。苗木根茎比不影响樟子松深栽造林的成活率和保存率。
Three kinds of seedlings with different heights and four different rhizome ratios were planted in 90%, 80%, 70%, 60% and 50% Pinus sylvestris afforestation planted as deep dew better. Seedling rhizome did not affect the survival rate and preservation rate of Pinus sylvestris plantation.
