常見樹穴的處置方法分析
1、種植花草
1. Planting flowers and grasses
樹穴種植花草是一種常見的處置方法，種植花草可以提高景觀的觀賞效果，使綠化效果更加美觀，更有層次感。但我們常見到種植在樹穴內的花草長勢欠佳，這里有諸多因素，如樹冠遮蔽陽光，樹木根系與花草爭奪水分、養(yǎng)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.
山東樹穴內種植花草不僅不利于花草的生長，對樹木的長勢也會有一定影響，因為樹穴內種花草，花草的根系較淺，特別是草坪，細密的根系會結成網狀，不利于氧氣流通。此外，花草的根系較淺，需要水分較多，經常澆水會導致土壤含氧量降低，會影響樹木根系的呼吸。在樹穴內種植花草的樹木遠不如裸露樹穴的樹木長勢好。
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、放置護樹板
2. Place the tree protection board
在很多大城市行道樹樹穴上都會放置著砼護樹板，這些護樹板非常美觀，而且可以有效防止垃圾進入樹穴。但由于護樹板是直接放置樹穴內的，加之其質量較重，長期放置會使土壤變得板結，而且護樹板還會減少自然降水的流入量。冬季的降雪也會因為無法堆積到樹穴內而白白浪費掉。
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
在一些庭院或者高檔小區(qū)、別墅區(qū)內，我們會經?？吹?，一些樹穴被裝飾得非常華麗，樹池用花崗巖制成，而為了顯得更上檔次，有些人將一些經拋光處理的河卵石放置于樹穴內，而且堆得滿滿的，幾乎和樹池一般高。此法看似合理，既不影響樹穴土壤的密實度，也不會妨礙雨水流入，但其實河卵石長期在樹穴內放置，時間久了樹穴的表土一樣會變得板結，畢竟河卵石的分量并不輕。
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方格網
4. Place PVC square grid
PVC方格網是近年來新興的一種樹穴防護材料，其具有質量輕、耐老化、易于移動等特點，在一些城市已經開始應用。這種方格網孔隙率高，利于水分流入，而且還可以防止垃圾掉進樹穴內，還便于清理衛(wèi)生，更重要的是它質量輕不會因為擠壓土壤而導致其板結?；谶@些原因，放置PVC方格網是處置樹穴的一個好辦法，既美觀又實用。
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.
