9种金花茶组植物在肇庆地区引种的早期评价
|
摘要
通过从广西引种9种金花茶组植物,并对不同种金花茶苗木在造林2 a后的成活率、苗高和地径生长进行对比试验研究。结果表明:防城金花茶(Camellia chrysantha var.phaeopubisperma)苗木成活率最高,达100%,珑瑞金花茶(C.longruiensis)苗木成活率最低,仅为73.3%;防城金花茶苗高生长量和地径生长量最大,分别为41.6、1.018 cm,显著大于其他8种金花茶(P<0.05),其中金花茶(C.nitidissima)苗高生长量和地径生长量最小,分别为6.5、0.147 cm;不同种金花茶苗木成活率、苗高生长量及地径生长量之间存在极显著的正相关关系(P<0.01)。苗木生长综合指标值分析表明,防城金花茶在肇庆地区的早期生长表现最好,在良种引种方面,可以适当选择防城金花茶。
The survival rate,height and the growth of ground diameter of 9 species of sect. Chrysantha were studied, The results showed that the survival rate of C. chrysantha var. phaeopubisperma seedlings were the highest, reaching 100%, and the survival rate of C.longruiensis seedlings were the lowest, only 73.3%. The growth and ground diameter of C.chrysantha var. phaeopubisperma seedlings were the highest, which were 41.6 and 1.018 cm, respectively, and there were significantly higher than the other Sect.Chrysantha(P<0.05). Among them, C.nitidissima had the lowest growth and ground diameter growth of 6.5 and 0.147 cm, respectively. There was a significant positive correlation among the survival rate, height growth and ground diameter growth of 9 species of sect.Chrysantha(P<0.05). Through the analysis of comprehensive index value of seedling growth, the C.chrysantha var. phaeopubisperma had the best growth performance in Zhaoqing and should be promoted in this area.
