Description

Technical Field

[0001] This invention belongs to the field of mountain planting technology, specifically relating to a method for artificially planting trees on rocky mountains. Background Technology

[0002] Many mountains in my country remain barren year-round due to their unsuitability for tree growth, especially rocky slopes. Even with artificial planting and care, trees struggle to survive, making large-scale afforestation to alter the ecology and landscape impossible. The primary reasons are that rocks are unsuitable for plant root growth and development, and secondly, trees cannot maintain balance on sloping hillsides. For example, very few Huangshan Welcoming Pine trees can successfully take root in rocks and grow. Even those that do survive in rock crevices face extremely limited living space, hindering their growth. To date, there is no effective method to improve the survival rate of trees planted on rocky slopes. However, with societal development and the increasing demand for afforestation, there is an urgent need for a method to improve tree survival rates and vegetation cover on barren mountains.

[0003] In existing technologies, such as the "A Tree Fixing Mechanism for Planting Trees on a Mountain" provided by Chinese Utility Model Patent Publication No. CN206620620U, the main problem is that the connection between the tree fixing mechanism and the mountain is not very firm, and the trees are easily affected by weather and soil erosion, which leads to the trees falling over. Although it can fix the trees on the hillside, it cannot guarantee that the trees can survive in the rocky environment, and still cannot meet the needs of afforestation on rocky mountains.

[0004] In view of the above, it is necessary to design a method that is conducive to artificial tree planting on rocky mountains and to improve the survival rate of trees and expand the living space of trees. To this end, the applicant has made a useful design, and the technical solution to be introduced below is generated in this context. Summary of the Invention

[0005] The purpose of this invention is to provide a method for artificially planting trees on rocky mountains, which is beneficial for modifying the growth environment of trees, enabling them to take root on rocky mountains and improving their survival rate. It also helps to expand rock crevices, improve the living space of trees, and promote tree growth.

[0006] The objective of this invention is achieved by providing a method for artificially planting trees on rocky hillsides, characterized by comprising the following steps:

[0007] A) Select a slope on the rocky mountain and delineate the planting area on the slope;

[0008] B) Excavate explosive holes in the rocky hillside within the planting area according to the set specifications and intervals;

[0009] C) Fill each explosive hole in the mountain with explosives and detonate them to create several irregular and fine cracks in the rocky mountain in the planting area, and fill each crack with soil.

[0010] D) Collect the mixture of gravel and mud produced by the explosion in step C), add cement and water to the mixture and stir thoroughly to obtain cement concrete, and use the cement concrete to pour a cement layer on the planting area.

[0011] E) Excavate explosive holes in the cement layer according to the set specifications and intervals after the cement layer has hardened. The depth of the explosive holes in the cement layer is less than the thickness of the cement layer.

[0012] F) Explosives are loaded into the explosive holes in the cement layer and detonated to create several irregular and fine cracks in the cement layer.

[0013] G) Lay a soil layer on top of the cement layer, and use the soil in the soil layer to fill the cracks in the cement layer during the laying process;

[0014] H) Plant seedlings on the soil layer and irrigate them thoroughly during the cold, freezing weather each year. The water fills the cracks in the cement layer and the mountain and freezes into ice. As the ice expands, it will open up the cracks in the cement layer and the mountain, providing more space for the roots of the seedlings to grow.

[0015] In a specific embodiment of the present invention, in step A), the slope angle is less than 50° and the planting area is 0.5-1㎡.

[0016] In another specific embodiment of the present invention, in step B), the diameter of the explosive hole in the mountain is 1-2cm, the depth is 20-30cm, and the distance between two adjacent explosive holes in the mountain is 10-20cm.

[0017] In another specific embodiment of the present invention, in step D), the mass ratio of the mixture of crushed stone and silt to cement is 3.5:1-2.5:1.

[0018] In another specific embodiment of the present invention, the thickness of the cement layer is 20-40cm; the thickness of the soil layer is 20-50cm.

[0019] In another specific embodiment of the present invention, the diameter of the explosive hole in the cement layer is 1-2 cm, the depth is greater than two-thirds of the thickness of the cement layer 2, and the distance between two adjacent explosive holes in the cement layer is 10-20 cm.

[0020] In a further specific embodiment of the present invention, the cement layer and the soil layer are surrounded by a perimeter.

[0021] In a further specific embodiment of the present invention, the surrounding edge is a plastic board, a plastic film, or a cement wall.

[0022] In yet another specific embodiment of the present invention, the explosive is a mining emulsion explosive.

[0023] In yet another specific embodiment of the present invention, the explosive charge filling the explosive holes in the mountain and the cement layer is 5-10g.

[0024] Compared with the prior art, the present invention has the following advantages: First, by constructing a cement layer on the rocky mountain and forming cracks in both the mountain and the cement layer, the seedlings can grow in the soil and take root in the cracks, thereby greatly improving the survival rate of the seedlings; Second, by watering the seedlings when the temperature drops to freezing point each year, the water in the cracks expands after freezing, gradually widening the cracks year by year, providing the seedling roots with more space to grow and effectively promoting the growth of the seedlings.

[0027] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.

[0028] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this invention.

[0029] This invention relates to a method for artificially planting trees on rocky hillsides, comprising the following steps:

[0030] A) Select a slope on the rocky mountain, the slope angle being less than 50°, and delineate a planting area 1 at a relatively flat location on the slope, the area of ​​the planting area 1 being 0.5-1㎡;

[0031] B) Excavate explosive holes in the rocky hillside within the planting area 1 according to the set specifications and intervals. The diameter of the explosive holes is 1-2cm, the depth is 20-30cm, and the distance between two adjacent explosive holes is 10-20cm. In this embodiment, the diameter of the explosive holes is set to 1cm, the depth to 30cm, and the distance between two adjacent explosive holes is set to 10cm.

[0032] C) Explosives are loaded into each explosive hole in the mountain and detonated to create several irregular and fine mountain cracks 11 on the rock mountain in the planting area 1. Soil is filled into each mountain crack 11. The soil can be selected according to the type of planting.

[0033] D) Collect the mixture of gravel and mud produced by the explosion in step C), add cement and water to the mixture and stir thoroughly to obtain cement concrete. The mass ratio of the gravel and mud mixture to cement is 3.5:1-2.5:1, preferably 3:1. Use this cement concrete to pour a cement layer 2 on the planting area 1. The thickness of the cement layer 2 is 20-40cm, preferably 30cm.

[0034] E) Excavate explosive holes in the cement layer 2 according to the set specifications and intervals after the cement layer has hardened. The diameter of the explosive holes in the cement layer is 1-2cm, and the distance between two adjacent explosive holes in the cement layer is 10-20cm. In this embodiment, the diameter of the explosive holes in the cement layer is set to 1cm, and the distance between two adjacent explosive holes in the mountain is 10cm.

[0035] F) Explosives are loaded into the explosive holes in the cement layer and detonated, causing the cement layer 2 to crack and generate several irregular cement layer cracks 21 inside. In order to prevent the debris generated after the explosion from blocking the mountain cracks 11, the depth of the explosive holes in the cement layer is less than the thickness of the cement layer 2, preferably more than two-thirds of the thickness of the cement layer 2. For example, when the thickness of the cement layer 2 is 30cm, the depth of the explosive holes in the cement layer can be selected as 25cm.

[0036] G) Clean the gravel off the cement layer 2 and lay a soil layer 3 on top of the cement layer 2. The thickness of the soil layer 3 is 20-50cm, preferably 30cm in this embodiment. During the laying process, the soil in the soil layer 3 will fill the cracks 21 in the cement layer.

[0037] H) Seedlings 4 are planted on the soil layer 3. During their growth, the roots of the seedlings 4 grow downwards along the cracks 21 in the cement layer and spread into the cracks 11 in the mountain. To improve the survival rate and the growing environment for the roots of the seedlings 4, this invention utilizes the principle of thermal expansion and contraction during the freezing process of water to widen the cracks 11 in the mountain and the cement layer 21. Specifically, during cold, freezing weather each year, the seedlings 4 are thoroughly irrigated, filling the cracks 21 in the cement layer and the cracks 11 in the mountain with water, which then freezes into ice. As the ice expands, it gradually widens the cracks 21 in the cement layer and the cracks 11 in the mountain, providing more space for the roots of the seedlings 4 to grow. When the temperature rises and the ice melts, the roots of the seedlings 4 have enough space to continue growing and spread further into the mountain. Through this process of irrigation and freezing every winter, the cracks 21 in the cement layer and the cracks 11 in the mountain gradually widen, making the roots of the seedlings 4 thicker and deeper, which not only improves the survival rate but also promotes faster growth of the seedlings 4.

[0038] In particular, in order to shape the cement layer 2 and soil layer 3 and prevent moisture loss, a perimeter 5 is also surrounded around the cement layer 2 and soil layer 3. The perimeter 5 can be a plastic board, plastic film or cement wall.

[0039] In this embodiment, the explosive is a mining emulsion explosive, and the explosive charge in the mountain explosive hole is 5-10g. Experiments have verified that this explosive charge, for the mountain explosive hole specified in this embodiment, is sufficient to blast the mountain to form the desired crack. The explosive hole in the cement layer is the same as the one in the mountain explosive hole.
