Embodiment 1

[0040] Follow the steps below:

[0041] 1. Determine the location of the hole. The location of the hole should be selected under the canopy to absorb the dense distribution of roots, and the distance between the holes is 140cm;

[0042] 2. The number of punching holes: according to the size of the canopy, within the range of 200cm, 4 holes are punched;

[0043] 3. The drilling depth is 35cm;

[0044] 4. The hole direction is vertical;

[0045] 5. After the hole is formed, puffed stone is placed in the hole as a filler.

Embodiment 2

[0047] Follow the steps below:

[0048] 1. Determine the location of the hole. The location of the hole should be selected under the canopy to absorb the dense distribution of roots, and the distance between the holes is 160cm;

[0049] 2. The number of punching holes: according to the size of the canopy, within the range of 400cm, 6 holes are punched;

[0050] 3. The drilling depth is 100cm,

[0051] 4. Drill holes obliquely at 45° from a distance of 50cm from the dry base to the densely absorbed root system;

[0052] 5. After the hole is formed, ceramsite is placed in the hole as a filler.

Embodiment 3

[0054] Follow the steps below:

[0055] 1. Determine the location of the hole. The location of the hole should be selected to absorb the dense distribution of roots under the canopy, and the distance between the holes should be 200cm;

[0056] 2. The number of punching holes: according to the size of the canopy, within the range of 600cm, 8 holes are punched;

[0057] 3. The drilling depth is 150cm;

[0058] 4. Drill holes obliquely at 45° from a distance of 75cm from the dry base to the dense absorption root system;

[0059]5. After the hole is formed, place the crushed stalk in the hole as a filler.

Abstract

The present invention relates to city greening, and is the hole drilling ventilation method for restoring a improving physiological function of avenue tree root system. Holes are drilled in the area with dense root distribution under tree crown, and 4-8 holes in 30-150 cm depth and 130-200 cm interval are drilled. The holes may be vertical or 45 deg inclined towards the area with dense root distribution, and are filled with stuffing with physical and chemical characteristics suitable for the soil. The said method can improve the ventilation and increase water content in soil and this is favorable to health growth of tree root system.

Description

technical field [0001] The invention belongs to a method for urban afforestation. Background technique [0002] Most cities in my country, especially the northern cities, after entering the mid-1990s, with the acceleration of urban infrastructure construction, the area of ​​hard surface pavement increased rapidly, and even under the guidance of the idea of ​​"improving the sanitation environment and improving the image of the city", The slogan that the loess is not exposed to the air was put forward. For the convenience of pedestrians, every city is "improving" the quality of pavement at the rate of hundreds of thousands or even millions of square meters per year. From the red bricks and ordinary cement square bricks in the past to today's high-hardness pavement bricks and square bricks, granite slabs have been laid in some places, and a cushion of composite soil and concrete has been added or thickened under the road surface. As a result, the soil outside the tree pit is c...
