选择苗木类型、坡向和坡位等3个对闽东北部杉木人工林有影响的因素来进行试验,对不同苗木类型、坡向、坡位影响杉木早期的生长情况进行研究。结果表明：杉木早期生长在不同苗木类型、坡向、坡位之间的成活率、地径和树高均存在显著差异；以 A3 B2 C3组合(扦插苗、半阳坡、坡下)有利杉木的早期生长,该组合3年生杉木地径达5.42 cm、树高达220.4 cm；以 A2 B1 C3组合(插条、阳坡、坡上)不利于杉木的早期生长,3年生杉木地径仅为2.79 cm,树高为119.1 cm。
選擇苗木類型、坡嚮和坡位等3箇對閩東北部杉木人工林有影響的因素來進行試驗,對不同苗木類型、坡嚮、坡位影響杉木早期的生長情況進行研究。結果錶明：杉木早期生長在不同苗木類型、坡嚮、坡位之間的成活率、地徑和樹高均存在顯著差異；以 A3 B2 C3組閤(扢插苗、半暘坡、坡下)有利杉木的早期生長,該組閤3年生杉木地徑達5.42 cm、樹高達220.4 cm；以 A2 B1 C3組閤(插條、暘坡、坡上)不利于杉木的早期生長,3年生杉木地徑僅為2.79 cm,樹高為119.1 cm。

Three factors (type,aspect and slope position)influencing Cunninghamia lanceolata plantation in north-ern Fujian Province were selected to conduct experiments.Effects of types,aspect & slope position of different seedlings on growth of C.lanceolata were studied.Result shows that the survival rate,ground diameter & tree height among types,aspect & slope position of different types ,aspect & slope position of different seedlings for early growth of C.lanceolata all have significant differences;A3 B2 C3 combination(cutting seedlings,semi-sunny slope,the lower part of the slope)is favorable for early growth of C.lanceolata.The ground diameter and tree height of (3-year-old C.lanceolata )the combination(A3 B2 C3 )is 5.42 cm,220.4 cm,respectively;A2 b1 C3 combi-nation(cutting seedlings,sunny slope,the lower part of the slope)is not in favor of early growth of C.lanceolata. Ground diameter and tree height of 3-year-old C.lanceolata is 79 cm and 1 1 9.1 cm respectively.
