不同林分林下套种草珊瑚的生长对比分析

Comparison of the growth traits of Sarcandra glabra under different interplanting patterns

对马尾松中龄林(处理1)、近熟林(处理2)及杉木中龄林(处理3)、近熟林(处理4)等四种林分林下套种的5年生草珊瑚进行调查分析。结果表明:4种林分林下套种草珊瑚的平均株高、地径以及干物质含量均表现为:处理3<处理1<处理4<处理2,且在马尾松近熟林分中套种的草珊瑚平均株高、地径分别达到了1.26 m、9.17 mm,分别高于杉木中龄林分的43.18%、37.07%;马尾松近熟林分中套种的草珊瑚单珠鲜重与干重分别达到了580.92 g、255.36 g,比杉木中龄林分的311.61 g、155.31 g分别高出86.43%、64.42%,马尾松近熟林分中套种的草珊瑚综合生长表现最好。

Sarcandra glabra were interplanted with different forest stands in Jiangle Country:half-mature Masson pine forest(group 1),near-mature Masson pine forest(group 2),half-mature Chinese fir forest(group 3),and near-mature Chinese fir forest(group 4).The tree height,ground diameter and dry matter content after 5 years'growth were examined to evaluate the interplanting mode.The results showed that all the growth traits exhibited the same pattern:group 3<group 1<group 4<group 2.In near-mature M.pine stand,the average tree height and ground diameter of S.glabra were 1.26 m and 9.17 mm,respectively,which were 43.18%and 37.07%higher than that of half-mature Chinese fir.The fresh weight and dry weight of interplanted S.glabra in near-mature M.pine stand were 580.92 g and 255.36 g,respectively,which is 86.43%and 64.42%higher than that of half-mature Chinese fir stand(311.61 g and 155.31 g).The interplanted S.glabra in near-mature stand of M.pine demonstrated the best performance in comprehensive growth.
