| 摘 要： | 对福建第3代杉木(Cunninghamia lanceolata)种子园子代林在广西前3年的生长表现进行研究,以探究福建种源在广西造林初期的适应性及竞争力。结果表明,子代林生长量在不同试验点及不同林龄间均存在显著差异;3年生子代林在广西整体表现为林分胸径与单株材积均显著高于对照。3年生子代林树高、胸径和单株材积分别为3.57 m、4.46 cm和0.004 m^3,分别高于对照5.04%、11.66%和26.89%。子代林在广西生长表现良好,生长优势明显,其中融水苗族自治县国营贝江河林场的造林效果较好,可为广西进一步开展杉木育种研究和良种基地建设提供更多的理论支撑和优质种质材料。

| Abstract: | Growth of Fujian third generation seed orchard progeny of Cumminghamia lanceolata in Guangxi was investigated to explore adaptability and competitiveness of Fujian provenance in early afforestation in Guangxi. Results showed that growths of progeny in Guangxi were significantly different in different test sites and different forest ages. The whole performance of progeny in Guangxi was that DBH and individual volume of three-year-old forests were significantly higher than those of control. Tree height, DBH and individual volume of three-year-old progeny forests were 3.57 m, 4.46 cm and 0.004 m^3, respectively, which were 5.04%, 11.66% and 26.89% higher than those of control. The progeny forests had good growth performances and obvious growth advantages in Guangxi. Afforestation effect of Rongshui state-owned Beijianghe forest farm was better, which could provide more theoretical support and high quality germplasm materials for further research on C. lanceolata breeding and construction of improved variety bases in Guangxi. |
