常见树穴的处置方法分析
1、种植花草
1. Planting flowers and grasses
树穴种植花草是一种常见的处置方法，种植花草可以提高景观的观赏效果，使绿化效果更加美观，更有层次感。但我们常见到种植在树穴内的花草长势欠佳，这里有诸多因素，如树冠遮蔽阳光，树木根系与花草争夺水分、养分等。
Planting flowers and grass in tree holes is a common disposal method. Planting flowers and grass can improve the ornamental effect of the landscape, making the greening effect more beautiful and layered. However, we often see that flowers and plants planted in tree holes are not growing well. There are many factors, such as canopy shading from sunlight, tree roots competing for water and nutrients with flowers and plants, and so on.
山东树穴内种植花草不仅不利于花草的生长，对树木的长势也会有一定影响，因为树穴内种花草，花草的根系较浅，特别是草坪，细密的根系会结成网状，不利于氧气流通。此外，花草的根系较浅，需要水分较多，经常浇水会导致土壤含氧量降低，会影响树木根系的呼吸。在树穴内种植花草的树木远不如裸露树穴的树木长势好。
Planting flowers and plants in tree holes is not only detrimental to the growth of flowers and plants, but also has a certain impact on the growth of trees. Because planting flowers and plants in tree holes has a shallow root system, especially on lawns, the fine and dense root system will form a network, which is not conducive to the flow of oxygen. In addition, flowers and grasses have shallow roots and require more water. Frequent watering can lead to a decrease in soil oxygen content, which can affect the respiration of tree roots. Trees that plant flowers and plants in tree holes do not grow as well as trees that are exposed in tree holes.
2、放置护树板
2. Place the tree protection board
在很多大城市行道树树穴上都会放置着砼护树板，这些护树板非常美观，而且可以有效防止垃圾进入树穴。但由于护树板是直接放置树穴内的，加之其质量较重，长期放置会使土壤变得板结，而且护树板还会减少自然降水的流入量。冬季的降雪也会因为无法堆积到树穴内而白白浪费掉。
In many large cities, concrete tree protection boards are placed on roadside tree holes. These tree protection boards are very beautiful and can effectively prevent garbage from entering the tree holes. However, due to the fact that the tree protection board is directly placed in the tree hole and its heavy weight, long-term placement will make the soil harden, and the tree protection board will also reduce the inflow of natural precipitation. Winter snowfall can also be wasted because it cannot be accumulated in tree holes.
3、放置河卵石
3. Placing river pebbles
在一些庭院或者高档小区、别墅区内，我们会经常看到，一些树穴被装饰得非常华丽，树池用花岗岩制成，而为了显得更上档次，有些人将一些经抛光处理的河卵石放置于树穴内，而且堆得满满的，几乎和树池一般高。此法看似合理，既不影响树穴土壤的密实度，也不会妨碍雨水流入，但其实河卵石长期在树穴内放置，时间久了树穴的表土一样会变得板结，毕竟河卵石的分量并不轻。
In some courtyards, high-end residential areas, and villa areas, we often see that some tree holes are decorated very luxuriantly, and the tree pools are made of granite. In order to appear more upscale, some people place some polished river pebbles in the tree holes, and the piles are full, almost as high as the tree pools. This method seems reasonable, neither affecting the compactness of the soil in the tree hole nor hindering the inflow of rainwater. However, in fact, if river pebbles are placed in the tree hole for a long time, the surface soil in the tree hole will become hardened over time, as the weight of river pebbles is not light.
4、放置PVC方格网
4. Place PVC square grid
PVC方格网是近年来新兴的一种树穴防护材料，其具有质量轻、耐老化、易于移动等特点，在一些城市已经开始应用。这种方格网孔隙率高，利于水分流入，而且还可以防止垃圾掉进树穴内，还便于清理卫生，更重要的是它质量轻不会因为挤压土壤而导致其板结。基于这些原因，放置PVC方格网是处置树穴的一个好办法，既美观又实用。
PVC square mesh is a newly emerging tree hole protection material in recent years, which has the characteristics of light weight, aging resistance, and ease of movement, and has been applied in some cities. This square mesh has a high porosity, which is conducive to water inflow, and can also prevent garbage from falling into tree holes. It is also convenient for cleaning and sanitation. More importantly, it is light in weight and does not cause soil to harden due to squeezing. For these reasons, placing PVC square grids is a good way to dispose of tree holes, which is both beautiful and practical.
