After the big tree is transplanted, it is usually necessary to set up pillars to prevent the tree from swinging and loosening due to strong wind blow, so that the root system does not grow well, empty holes form around the base of the trunk, and it is easy to accumulate water in the dry cavity during the rain and affect the root system. And above ground growth. At the same time, due to the shallow root system and small distribution area after transplanting large trees, the erection of pillars can prevent the trees from falling unfavorably due to uneven stress. The erection pillars are generally completed in the planting operation and are performed before the watering. When erecting the pillars, the wind direction at the point where the big tree is located needs to be taken into consideration, and the support position is generally chosen to focus on the downwind direction at the planting point. The pillar material should be selected according to the tree species and the specifications of the trees. It should be practical and attractive. There are several ways to erect the pillars. Single pillar Planting plant trunk parallel to the vertical pillar. Always erect standing pillars at the center of the planting hole before planting. After the soil is completed, tie the top of the pillar and the near ground to the trunk of the tree to prevent the big tree from shaking. In order to prevent the tree trunk from being injured, it does not affect the growth of the trunk. Soft cushions should be added between the pillars and the trunk. At the same time, the space between the pillars and the trunk should be properly reserved. 2. Gable pillar For trees with a trunk diameter of 10-15 cm, after the planting is completed, a bamboo-wood pillar with a height of approximately 1-1.5 m shall be drilled at approximately 50-70 cm on both sides of the corresponding trunk. The two poles are connected to two poles, tied tightly, and the central position of the trunk is aligned with the trunk, and then the rails and the trunk are clamped to prevent shaking. There must be a septum between the bar and the trunk to prevent galling of the bark. After the root system can play a good role in the solid can be removed after the stent, generally preserved for one year after planting. 3. Herringbone pillars After the big trees are planted, a bracing strut is erected on both sides of the tree to form a “person†shape. In order to make the pillars firm, it is also possible to form a triangle with the trunk. Using the trunk as a pillar, the pillars and the trunk are tied together to prevent the roots from shaking. Although this pillar has less material, it is relatively poor in stability and is suitable for street trees. The direction of the support is parallel to the road, and it has less interference with the sidewalk. 4. Triangle pillars Using three bamboo or wooden sticks to form a triangle, the upper corners and trunks are tied together to support the trunk. The height of the stand is determined by the height of the tree. When a triangular stand is erected on a road, the lower leg often hinders pedestrians because of support and the supporting angle is too small and firm, so it is often applied when the open green space is planted. In order to increase the firmness of the stent, a lumbosacral ridge is often added in the middle, and the lumbosacral and the trigonal stent are fixed. In addition, a cushioning material should be added to the site of contact with the trunk so as not to injure the bark. In order to make the bracket stable, the standing pillar often tops the base of the pillar on the pit and is embedded in the soil within 30-40 cm. This type of support is mostly used for cedar, pine needles, broad magnolia, etc., or particularly tall tree arbors. 5. Pull wire fixation Some tree crowns are relatively tall, and the standing pillars cannot completely solve the stability problem, especially the evergreen trees with earthballs. The crowns are large, the root system is very small after transplanting, and the center of gravity is high. Therefore, the method of piling and pulling steel wire to fix the trunk is commonly used. Pull wire according to the size of the crown and the distribution of branches and leaves, generally 1-3 root. When pulling one, pull it on the side with less foliage. First hit a pile on the ground, and then use one end of the steel wire to hold the middle of the main point of focus, the other end on the stake. The padding between the trunk and the wire is good. Pull wire angle (with the main angle) with 40-60 is appropriate. Pull two wires on each side of the tree; pull three wires to maintain an angle of 120 between them. 6. Four-post type In order to increase firmness, four pillars can also be used. Four pillars are erected evenly around the trunk and the upper part is fixed to the tree body with crossed pillars. 7.# character support To make the support firm, often use a #-shaped support. The four pillars are erected evenly around the trunk and are all slightly inclined towards the trunk. The upper part is fixed with four crossbars and pillars of appropriate length. After the four crossbars form a square, the trunk is fixed at the central position. 8. Rows of network shapes After each newly planted tree is supported and fixed by an appropriate method, in order to increase the firmness of the fixed tree body, adjacent trees are often fixed together with a cross bar, forming a network in a row. This method has been applied to the cultivation of large-area, large-size arbor supports. Although it has increased investment, it is beautiful, neat, and strong. Of course, not all planting trees need to be pillared. For those deciduous trees such as Platanus platyphylla, Podocarpus, Populus tomentosa, Pterocarya falcate, etc. that have undergone the crown treatment, the pillars of the stroke may not be erected depending on the conditions.
