摘　　要：为研究5个不同种源杉木苗造林生长差异,设置融江河流域实生苗为对照(CK),在融安县西山林场开展造林试验。初期调查结果表明:红心杉造林1年成活率最高,为94.5%,最低的是贝江1.5,为84.0%;造林后3年保存率最高的是西山1.5,为92.0%,最小的是CK,为81.0%。6个参试的种源4年生的平均树高、平均胸径、平均材积间差异达显著水平,平均树高大小依次为西山1.5>贝江1.5>咸水2>糠杉>红心杉>CK;平均胸径大小依次为贝江1.5>西山1.5>咸水2>糠杉>红心杉>CK;平均材积大小依次为贝江1.5>西山1.5>咸水2>糠杉>红心杉>CK;平均冠幅差差异不显著。综合各生长性状指标,西山1.5、贝江1.5在试验当地表现最优,适宜广西北部推广栽植。In order to study the growth difference of Cunninghamia lanceolata(Lamb.)Hook.seedlings of 5 different provenances in afforestation,the afforestation experiment was carried out in Xishan Forest Farm of Rong'an in which seedlings in Rongjiang River Basin as CK.Preliminary in-vestigation results showed that:survival rate of red-heart Chinese fir in afforestation was the highest,94.5%,and the survival rate of Beijian 1.5th generation(Beijian 1.5)was the lowest,84.0%;the highest preservation rate in 3 years after afforestation was found in Xishan 1.5th generation(Xishan 1.5),92.0%,and the lowest was found in CK,which was 81.0%.The average height(H),average di-ameter(D)and average volume(V)of the 4-year-old trees of 6 provenances in the experiment was a significantly different.The average H was in the order of Xishan 1.5>Beijiang 1.5>Xianshui 2>bran Chinese fir>red-heart Chinese fir>CK;and the average D was in the order of Beijiang 1.5>Xishan 1.5>Xianshui 2>bran Chinese fir>red-heart Chinese fir>CK;the average V was in the order of Beiji-ang 1.5>Xishan 1.5>Xishan 1.5>bran Chinese fir>red-heart Chinese fir>CK;the difference of aver-age crown width was not significant;according to various growth trait indexes,Xishan1.5 and Beiji-ang1.5 performed the best in the test area and are suitable to be planted in northern Guangxi.
