经过１４年的多点多重复试验研究，选出了适合贵州山地的优良杉木种源。并在杉木边缘产区和杉木一般产区进行了丰产林营建技术的研究。林木５年生时：在边缘产区的毕节试验林与当地普通林分比较，树高增加８４％，胸径增加１０６％；在一般区的湄潭与《贵州省杉木丰产林标准》比较，树高超过４９％，胸径超过８３％。
After 14 years of multi-point multi-trial study, we selected the best provenance of Chinese fir source. And in the fringe producing areas and fir general producing areas of high yielding forest construction technology research. Five-year-old trees: In the marginal zone Bijie experimental forest compared with the local ordinary stands, the tree height increased 84%, DBH increased 106%; Meitan in the general area and the “Guizhou fir high yield forest standards”, the tree height Over 49%, DBH over 83%.
