在福建省建宁县开展钟萼木与杉木株间混交、钟萼木纯林造林对比试验,结果表明:8年生钟萼木杉木混交林的生长量显著高于钟萼木纯林,混交林中钟萼木的平均地径达3.7 cm、平均树高达3.02 m、平均保存率达91.4%,分别比纯林高出15.6%、9.0%、6.7%;钟萼木林分下坡的平均地径达4.4 cm、平均树高达3.65 m、平均保存率达91.7%,分别比中坡高出29.4%、32.2%、7.3%,分别比上坡高出69.2%、65.1%、14.3%;钟萼木杉木混交林郁闭度达0.7,显著高于钟萼木纯林郁闭度0.25。
在福建省建寧縣開展鐘萼木與杉木株間混交、鐘萼木純林造林對比試驗,結果錶明:8年生鐘萼木杉木混交林的生長量顯著高于鐘萼木純林,混交林中鐘萼木的平均地徑達3.7 cm、平均樹高達3.02 m、平均保存率達91.4%,分彆比純林高齣15.6%、9.0%、6.7%;鐘萼木林分下坡的平均地徑達4.4 cm、平均樹高達3.65 m、平均保存率達91.7%,分彆比中坡高齣29.4%、32.2%、7.3%,分彆比上坡高齣69.2%、65.1%、14.3%;鐘萼木杉木混交林鬱閉度達0.7,顯著高于鐘萼木純林鬱閉度0.25。

Based on 7-year-long Bretschneidera sinensis and Cunninghamia lanceolata mixed forest,and Bretschneidera sinensis pure forest afforestation compare experiment ,results showed that:the growth of 8-year-old Bretschneidera sinensis and Cunninghamia lan-ceolata mixed forest was significantly higher than that of B.sinensis pure forest,the average B.sinensis plantation diameter was 3.7 cm,the average tree height was 3.02 m,the average saving rate was 91.4%,were 15.6%,9.0%,6.7%higher than pure forest;the average of B.sinensis downhill afforestation diameter was 4.4 cm,the average tree height was up to 3.65 m,the average saving rate was 91.7%,respectively,were 29.4%,32.2%,7.3% than the downhill,and 69.2%,65.1%,14.3% higher than the uphill.The mixed forest canopy density was 0.7,0.25 higher than that of B.sinensis pure forest canopy density significantly.
