【目的】通过比较不同生长时期果林间种与单种模式下南板蓝的株高及分枝数的动态变化规律,阐明南板蓝的生长发育规律。【方法】分别将南板蓝种植于无遮荫种植地、蕉林地及柑橘林地中,每月定期测量南板蓝植株高度、每株各回分枝数及总分枝数,进行统计分析。【结果】南板蓝各模式组在不同生长时期的株高、各回分枝数及总分枝数均呈现上升趋势,但间种组各指标值均高于单种组。各种植组南板蓝的株高于5～11月份生长迅速,12月则生长缓慢;各组平均总分枝数5～8月份增长缓慢,9～12月份则增长加快。【结论】蕉林及柑橘林为南板蓝的生长提供了良好的荫蔽环境,间种模式比单种模式更利于南板蓝的生长。
【Objective】 The objective of this study was to clarify the law of growth and development of M. nigra by comparing the dynamic changes of plant height and branch number of P. nigra in different intercropping and intercropping periods. 【Method】 Southern Banlangen was planted in shady-free planting land, banana land and citrus woodland respectively. The height of Banlangen, the number of branches and the total number of branches per plant were regularly measured every month for statistical analysis. 【Result】 The results showed that the plant height, the number of branches and the total number of branches in different patterns of growth increased with the growth of each pattern. However, the index of each species was higher than that of single species. The growth rate of the southern blue plants in each planting group was higher than that in May-November, but slowed in December. The average total number of branches in each group increased slowly from May to August, and accelerated from September to December. 【Conclusion】 The banana plantations and the citrus groves provide a good shade environment for the growth of southern Banlanger. The intercropping mode is more favorable for the growth of southern Banlanger than the single mode.
