Waterproof site tree planting method suitable for park place tree array

Abstract

The invention relates to a waterproof site tree planting method suitable for park place tree array. Planting holes are dug or expanded according to planting orientation before surface pavement; bodiesof the planting holes are in inverted cone shape with big end down; when the planting holes run through a waterproof layer and connect with a lower water-permeable area, a coarse sand layer is laid at the bottom of each planting hole; when the planting holes do not run through the waterproof layer, a gravel layer is laid at the bottom of each planting hole; a surface water pumping pipe is provided; trees with an earth ball are lifted during planting, a water pipe is extended into the lower portion of a tree planting earth layer or below the same for irrigation, water flows up from the bottomand mixes with planting earth to form mud, and the trees are released and naturally fall to a set height. The method herein has the advantages that post-planting survival rate of trees in the waterproof area can be increased, the future trouble of changing trees after planting is alleviated or eliminated, and maintenance difficulty and workload are decreased.

Description

technical field [0001] The invention relates to a method for planting trees on an impermeable site suitable for tree arrays in parks and squares, and belongs to the technical field of tree planting. Background technique [0002] With the great improvement of people's living environment, various leisure and recreation parks are blooming everywhere. Large-scale trees are planted in the form of rectangular tree arrays or symmetrically in the park entrance square, the square for exercise and the parking lot. While satisfying the landscape effect To achieve the shading effect, the tree diameter at breast height, crown width and branch points must be basically the same, the rows must be neat and consistent, and the specifications of the planting holes must be consistent. However, usually the reserved tree pots in these areas are small, and the roadside stones are often used as cofferdams. The parts outside the cofferdams are paved with stone materials, such as marble slabs, and sh...

AI Technical Summary

Problems solved by technology

[0009] 1) The measures of reducing the tree crown and soil ball and planting at a higher height can help reduce the requirements for planting holes and promote the survival of trees, but cannot guarantee the landscape effect

Under these measures, the growth of the root system is inhibited, and the growth of the tree body is slow. Not only can it not achieve the landscape effect of quickly becoming a forest, but it also grows slowly after survival. ground cover;

[0010] 2) Taking heavy pruning measures cannot guarantee the landscape effect, and also inhibits the growth of trees, especially their root systems, resulting in slow growth of trees;

[0011] 3) Take the measures of paving gravel at the bottom of the planting hole and installing a hose, which will help the trees survive, but you must also observe the change of the water level at any time. Once the rainfall is heavy or after watering, you must use the hose to remove the gravel above the layer in time. The accumulated water is pumped out in time, which obviously increases the workload and difficulty of maintenance. Since it is difficult to achieve the ideal state in practice, the phenomenon of tree death due to waterlogging cannot be completely eliminated. In addition, the exposed thick hose also affects the appearance
