摘要
为了解不同郁闭度杉木林下岗梅的生长情况,选择郁闭度为0.1、0.2、0.4、0.6、0.8的杉木林地套种岗梅,以探索杉木林套种岗梅的最适宜郁闭度.结果表明:杉木林下套种岗梅的最佳郁闭度为0.4,此时岗梅农艺性状表现最优,株高、主杆粗和根粗均最大,分别为(145.00±11.76)、(1.63±0.12)和(1.54±0.08)cm;根长次高,为(31.65±1.17)cm;根部重量和枝杆重量均最大,分别为(376.66±25.87)g和(720.00±101.03)g.相关性分析表明株高分别与枝杆重量和根部重量呈极显著和显著正相关,可作为评价岗梅产量的重要指标.
Abstract
In order to understand the growth of Ilex asprella under Chinese fir forest with different canopy densities,the Chinese fir forest land with the canopy density of 0.1,0.2,0.4,0.6 and 0.8 was selected for intercropping with Ilex asprella,in order to explore the most suitable canopy density of Chinese fir forest to interplant Ilex asprella.The results showed that,the best canopy density of Chinese fir forest for intercropping with Ilex asprella was 0.4.At this time,the agronomic traits of Ilex asprella were the best,and the plant height,main stem diameter and root diameter were the largest,which were (145.00±11.76),(1.63±0.12) and (1.54±0.08) cm,respectively.The root length was (31.65±1.17) cm.The root weight and branch weight were the largest,which were (376.66±25.87) g and (720.00±101.03) g,respectively.The correlation analysis showed that the height of Ilex asprella was significantly positively correlated with branch weight and root weight,respectively,which could be used as an important indicator for evaluating the quality of Ilex asprella.
