摘要:
为筛选适合赣南地区生长的杉木Cunninghamialanceolata良种,本试验对6种不同世代不同类型杉木良种造林后的树高、胸径、材积生长量进行方差分析和多重比较。结果表明:杉木不同世代不同类型良种试验林的平均树高、胸径和材积生长量均存在显著差异(P<0.01);4年生与5年生的杉木良种中,洋口3代良种表现最佳,其树高、胸径均显著大于其他良种(P<0.01);7年生时,同样是洋口3代杉木良种生长表现最好,杉木平均材积生长量为0.040 0 m3,高出平均材积生长量的29.45%,其次是信丰杉木2代、信丰杉木1代良种,其造林后6 a材积生长量显著高于陈山红心杉1代(P<0.01)、融水种源杉木林分良种与洋口杉木2.5代。本试验结果表明,杉木高世代良种具有较明显的增产效果;选择当地选育的杉木良种造林能够取得较好的增产效益。
Abstract:
In March of 2011, 1-year seedlings of Cunninghamialanceolataof 6 different generations and different types were planted in Ganzhou of Jiangxi province.Determinations were carried out on height, DBH and volume in October of 2013 and 2014, August of 2016.The result showed that it had evident difference of mean height, DBH and volume growth of tested seedlings in different determination year.The experiment demonstrated that seedlings from Yangkou3th generation seed orchard had the best growth in terms of height, DBH and volume, the mean volume of 7-year was 0.040 m3, higher than the average volume by 29.45%.The test concluded that advanced generation had higher yield increase, and local recommended seeds had better effect.
