榕树,是我国盆景艺术常用的树种之一,以根繁叶茂、千姿百态而著称。笔者根据多年的经验,首先谈一下榕树对土壤的适应特点。对于树龄不大,为了培养其根须发达的树苗,最好是选取松软、粘性不大的沙质土,它透气度好,对水分的渗透和蒸发有很大的优越性,只要定期适当施肥,所培植的榕树的根会大量向四面扩展,叶子变得圆、大而且呈青绿色。树根培养到了一定的程度以后,要对树干和根进行包扎,这时期选取的土壤最好是较稠密、少沙子的壤土。但要注意少施肥,这样树干的生长就非常慢,有利于造型。另一方面,如果树龄较大,而且姿态几乎定型,可立即上盆的树桩,这时候选取的土壤更要讲究,应选用酸性较强,稠密,硬度大的土壤,以酸粘土最好。榕树在这种土壤里生长了一定时期后,叶子会渐渐变得狭小、圆滑,呈现翠青色,非常美丽。以上是土壤对榕树的影响。下面想谈一下榕树老 Banyan tree is one of the commonly used species of bonsai art in our country. Based on years of experience, I first talk about the adaptability of banyan to soil. For the tree age is not big, in order to cultivate the roots of its developed saplings, it is best to choose soft, small viscous sandy soil, it is good air permeability and evaporation of water has great advantages, as long as the proper fertilization regularly , The roots of the banyan cultivated will expand in all directions and the leaves become round, large and turquoise. Tree roots to a certain extent, after the trunk and root to be dressing, the best selected soil during this period is more dense, sandy loam. But pay attention to less fertilization, so the growth of the trunk is very slow, is conducive to modeling. On the other hand, if the age of the tree is relatively large and the shape is almost fixed, the stumps of the pot can be placed immediately. At this time, the soil to be selected should pay more attention to it. Soil with strong acidity, denseness and hardness should be selected and acid clay is the best choice. After the banyan grows in this soil for a certain period of time, the leaves gradually become narrower, smoother, and appear vivid and beautiful. The above is the impact of soil on the banyan tree.
