摘要
榕树Ficus microcarpa是岭南地区主要的乡土园林树种之一。探究了未腐熟基质二次发酵产生的高温对刚移植的榕树大树新根生长的影响,结果表明:在基质发酵产生高温的情况下,榕树新根的生长与土壤温度成负相关;环沟控温处理可有效降低基质发酵产生的高温,给新根提供适宜的生长温度。
Ficus microcarpa is a primarily kind of native landscape tree in Lingnan area. This study explored the effects of soil temperature on the new root growth of Ficus microcarpa under the condition of secondary fermentation of undecomposed cultivation medium. The results show that Ficus microcarpa root growth was negatively correlated with soil temperature under high temperature leaded by fermentation. The management of temperature by circular groove effectively reduced the high temperature induced by substrate fermentation, and suitable soil temperature were given.
