野外树桩是目前盆景生产的主要材料。为了有效利用有限而宝贵的野生植物资源,树桩的采挖和培育成了园艺生产者重要的研究课题,在此仅谈点个人的浅见。首先采挖要适时。各种植物由于生态习性不同,移植成活难易也不同,对同一种植物来说,移植成活率与移植时间有很大关系,一般从植物休眠到春芽萌动前均适于采挖,但最适采挖期应是在新芽将萌动但尚未萌发时,这需要依当时当地的实际情况具体掌握。如在尖峰岭,九里香的采挖在三月中下旬至四月上旬为宜。其次要尽可能不损伤须根和对受伤根系进行认真处理。须根是植物吸收水份和养料的重要器官,山野采挖和运输过程中,如不注意最先受损的必是须根,须根损伤就减少了树桩移植成活的可能。因此山野采挖树桩要把保护须根作为重要的考虑因素,最好尽可能带较大的土球。采挖树桩必然要截断树根,树根截断后伤口极易流胶液和受病菌侵
Wild stumps are the main material for bonsai production. In order to make effective use of the limited and valuable resources of wild plants, stump excavation and cultivation has become an important research topic for horticultural producers. First digging should be timely. Due to the different ecological habits of various plants, transplantation is easy and different. For the same plant, the survival rate of transplantation is closely related to the time of transplantation. Generally, it is suitable for excavation before dormancy until spring bud germination, but most Appropriate digging period should be in the sprout will germinate but not yet germinated, which needs to be based on the actual situation at that time to grasp. As in the peak ridge, nine miles of the excavation in late March to early April is appropriate. Second, as far as possible without damaging the fibrous roots and the root cause of serious treatment. Stem is an important organ that plants absorb water and nourishment. In the process of digging and transporting in the mountains, if the first damage is noticed, it must be a fibrous root, which will reduce the possibility of stump transplant. As a result, the protection of the fibrous roots should be taken as an important consideration in the excavation of the tree stumps in the mountains so that it is better to bring larger soil balls as much as possible. Tree stumps must be cut truncated tree roots, cut off the roots easily after the wound fluid and bacterial invasion
