摘要
在福建省仙游县建林林业专业合作社苗圃,对产自福建省洋口国有林场等10个单位14个1~3代的杉木种子园良种开展苗期生长特性对比试验。结果表明:14个良种的生长指标间均存在显著或极显著差异,苗高、地径、生物量均值最大的分别是:尤溪林场第3代、尤溪林场第3代、洋口林场第3代;综合苗高、地径、生物量性状,利用多性状综合分析结果表明,尤溪林场第3代的综合表现最优(多性状综合评价Pi值最小)、其后依次是洋口林场第3代、光泽华侨林场第3代、官庄林场第2.5代、南平市郊林场第1代、尤溪林场第2代、洋口林场第2.5代、政和林场第1代、长汀第2代、建瓯市第1.5代、尤溪林场第1代、浙江省龙泉市第2代、洋口林场第1.5代、官庄林场第1.5代。
In the nursery of Fujian Xianyou County Jianlin Forestry Professional Cooperatives,the seedling growing comparative experiment was conducted by using the seeds from 14 first-third generation improved varieties of Cunninghamia lanceolata seed orchard produced in Yangkou National Forest Farm,etc total 10 institutes.The results showed that there were significant or extremely significant differences among the 14 improved varieties in all growing indexes;the maximum mean value of seedlings high,diameter and biomass was Youxi Forest Farm 3^rd generation,and Youxi Forest Farm 3^rd generation and Yangkou Forest Farm 3^rd generation,respectively;by using multi-character integrated analysis method,the integrated characters of seedlings high,and diameter and biomass showed Youxi Forest Farm 3^rd generation was the best（multi-character integrated evaluation Pivalue was minimum）,subsequently followed by Yangkou Forest Farm 3^rd generation,Guangze Overseas Chineses Forest Farm 3^rd generation,Guangzhuan Forest Farm 2.5^th generation,Nanping Suburb Forest Farm 1^st generation,Youxi Forest Farm 2^nd generation,Yangkou Forest Farm 2.5^th generation,Zhenghe Forest Farm 1^st generation,Changting 2^nd generation,Jian＇ou 2^nd generation,Youxi Forest Farm 1^st generation,Zhejiang Longquan 2^nd generation,Yangkou Forest Farm 1.5^th generation and Guanzhang Forest Farm 1.5^th generation.
