摘要
以连续发生的季节性干旱天气为背景,对肇庆市国有清桂林场二年生杉木区域试验林中不同品系的适应性及生长表现进行测定分析。结果表明,不同杉木品系生长性状差异较为显著,2021年地径变异系数较大,达到33.5%。综合保存率、树高、地径生长情况,广东杉木2.5代种子园子代表现最佳,其次为T-c04、TL5、洋061等品系,T-c07和洋020在此次测定中表现不佳。
Under the background of continuous seasonal drought weather,the adaptability and growth performance of different strains of Cunninghamia lanceolatar was measured and analyzed in a 2-year-old Cunninghamia lanceolatar regional experimental forest of Qinggui State-owned Forest Farm in Zhaoqing City.The results showed that there were significant differences in growth traits among different Cunninghamia lanceolatar strains,and the ground diameter variation coefficient was larger(33.5%).According to the storage rate,tree height and ground diameter growth,Guangdong Cunninghamia lanceolatar 2.5 generation seed garden offspring had the best performance,followed by T-c04,TL5,Yang 061 and other strains,T-c07 and Yang 020 were not good in this test.
