Detailed Description
Example 1:
as shown in fig. 1 and 6, the special-shaped planting holes for saving planting soil and directionally promoting root growth are special-shaped planting holes, the special-shaped planting holes are special-shaped cylinders inscribed in a circle, and the cross sections of the special-shaped cylinders are triangular or polygonal star-shaped inscribed in the circle.
In the preferred scheme, the radius of the triangle inscribed circle or the radius of the multiangular star inscribed circle is 20-50cm larger than the root system and soil ball of the planted plant.
In the preferred scheme, the depth of the tree pit is higher than the height of the soil ball for planting plants;
used for filling the special-shaped column body with the compost.
The multi-angular star is a five-angular star inscribed in the circular basic tree pit.
Example 2, as shown in fig. 2, the cross section of the profile cylinder is a triangle inscribed in a circle, compared with example 1.
In example 3, as shown in fig. 3, the polygonal star shape is a cross shape inscribed in a circular basic tree hole, as compared with example 1.
In example 4, as shown in fig. 4, the polygonal star shape is a hexagonal star shape inscribed in a circular base tree well, as compared with example 1.
In example 5, as shown in fig. 5, the polygonal star shape is a rice shape inscribed in a circular base tree hole, as compared with example 1.
The five embodiments ensure that the plant root system has enough placing space, and simultaneously determine the plane configurations of five heterotype tree holes, wherein the respective core parameter data are respectively shown in the following table:
TABLE 1 abnormal pit core parameters
Wherein the radius of the circumscribed circle is specifically determined under the condition that the plant root system grows in the basic space. The requirement is that the special-shaped tree holes inscribed in the diameter can provide sufficient growing space for accommodating the root systems of the plants.
