In addition, the present invention has differences according to the Tree root system direction of growth, therefore arbor is classified according to deep root system with shallow root system.
To devise the plantation circle of money different structure form.
Deep root system arbor is mostly the system of taproot, and the root of plant has point of apparent primary and secondary root.Root system is along Vertical Square
To growth.The different arbor diameters of a cross-section of a tree trunk 1.3 meters above the ground are different simultaneously, and there is also differences for the height of growth, therefore the present invention is having studied deep root system arbor
In aiphyllium cinnamomum camphora, wide yulan；Deciduous tree ginkgo, weeping willow etc. show that the size of plantation circle should be using the arbor diameter of a cross-section of a tree trunk 1.3 meters above the ground as base
Plinth determines.
When plantation circle ontology is for when planting deep root system arbor, plantation circle ontology with a thickness of 10~15cm, plantation
It encloses body upper part narrow end and upper soll layer distance is 15~20cm, the buried depth of plantation circle ontology is between 15+h~20+h cm；Kind

At least value of the Tree growth after 30 years.Plantation circle thickness takes 10cm to be preferred between 10~15cm, and thickness is in 10~15cm
When plantation circle be not only able to satisfy Planning effect to shade tree root system, but also blocked up subsequent installation will not be caused to go wrong.
In addition, the root system of deep root system arbor is located at plantation circle upper bottom surface middle position, plantation circle will tree in the form of wrapping up
Root protects, and prevents the root system of deep root system arbor from growing along different directions, ejects ground failure road, endangers citizen's health.
When plantation circle ontology is used to plant deep root system arbor, the upper hollow of the plantation circle ontology is conducive to the lower infiltration of moisture,
The infiltration of air plans the root system of deep root system arbor under the premise of not influencing deep root system arbor normal growth, maintains road
It is flat.According to the rule of the root growth of deep root system arbor, i.e. main root is taken root downwards, sturdy obvious, by main root top set difference
Lateral root, lateral root are grown centered on main root according to the form that dissipates outward, and lateral root is compared thin and short for main root.The present invention will plant
The hole for planting the vacancy section of circle ontology is circular hole a, aperture 5cm-12cm, the spacing between two neighboring circular hole a
For 5cm, for the setting of deep root system arbor quantity of the hole diameter between 5~10cm need to be greater than hole total quantity 1/2 and
It is even to be distributed in plantation circle bottom；Circular hole a is divided into three classes according to diameter, corresponds to aperture between 11-12cm
