Problems solved by technology

[0004] 1. The base point of the tower is located on the hillside or on the top of the mountain, and the transportation of ecological restoration materials is difficult and costly
[0005] 2. The location of tower foundation project lacks water source and power supply, but for ecological restoration construction, the two are particularly important. At the same time, the maintenance of vegetation after construction is the most critical. The focus of maintenance is to ensure water source
[0008] 5. The particularity of the location of the mountain tower foundation itself leads to difficulties in the transportation of materials and the management and maintenance of plant measures after construction; the time for the ecological restoration of the mountain tower foundation determines the selection and matching of plant measures, and the plants are faced with winter and Adaptability issues for spring season switching
[0011] 2. The simple grass seed sowing technology requires good soil quality in the construction area. At present, the construction of mountain tower foundations is faced with limited construction sites, difficult topsoil protection, and poor soil conditions on site. It is difficult to provide stable conditions for plant growth.

Embodiment 1

[0026] Step 1 Taki soil improvement. The area of ​​the tower base is 9260㎡, and the surface soil on the site of the tower base has been removed. To meet the requirements of ecological restoration, the site is plowed to a depth of 33cm; after plowing, 0.06kg / ㎡ of water-retaining agent, 1 liter / ㎡ of peat soil, and organic fertilizers are added 4kg / ㎡, biological agent 0.04kg / ㎡, make it evenly mixed to improve the fertility and water retention of tower foundation soil.

[0027] Step 2 adopts the plant configuration method of ryegrass + bahia grass + pigeonpea, the configuration ratio is (1:1:2), and the amount of mixed grass seeds per square meter is 28g / ㎡.

[0028] Step 3 Grass sowing. Seed soaking and disinfection of grass seeds: Use 50% carbendazim WP to prepare a 0.3% solution, stir and soak the seeds for 24 hours. Sowing: After the soil improvement of the site is completed, move back and loosen about 2cm of the topsoil with a working rake, and sow seeds on the loosened tops...

Embodiment 2

[0032] Step 1 Taki soil improvement. The site area of ​​the tower foundation site is about 700㎡, and the surface soil has been removed. To meet the ecological restoration requirements, the site must be tilled at a depth of 45cm; after tillage, 0.08kg / ㎡ of water-retaining agent, 1.2 liters / ㎡ of peat soil, and 6kg of organic fertilizer should be mixed / ㎡, biological agent 0.06kg / ㎡.

[0033] Step 2: Plant configuration for ecological restoration of tower base. This plan adopts the plant configuration method of tall fescue + bermudagrass + bermudagrass, with a configuration ratio of 1:1:1.5, and the amount of mixed grass seeds per square meter is 35g / ㎡.

[0034] Step 3 Grass sowing. Prepare a 0.5% solution with 50% carbendazim wettable powder, stir and soak the seeds for 24 hours. Sowing: After the soil improvement of the site is completed, move back and loosen the surface soil about 2cm with a working rake, and sow the seeds on the loose surface soil according to the seeding r...

Embodiment 3

[0038] Step 1 Taki soil improvement. The tower base site is about 1000㎡, and the topsoil will be generally removed. To meet the requirements of ecological restoration, the site must be tilled to a depth of not less than 40cm; after tillage, 0.07kg / ㎡ of water-retaining agent and 1.2 liters of peat soil should be mixed in , Organic fertilizer 5kg / ㎡, biological agent 0.06kg / ㎡, mix them evenly to improve the fertility and water retention of the tower foundation soil.

[0039] Step 2: Plant configuration for ecological restoration of tower base. This plan adopts the plant configuration method of ryegrass + tall fescue + bahia grass + pigeonpea, the configuration ratio is (1:1:2:4), and the amount of mixed grass seeds per square meter is 30g / ㎡.

[0040] Step 3 Grass sowing. Grass seed soaking disinfection: use 50% carbendazim wettable powder to prepare a 0.4% solution, stir and soak the seeds for 24 hours. Sowing: After the soil improvement of the site is completed, move back and...

Abstract

The invention discloses a method for rapid ecological restoration of a mountain tower footing. Aiming at the defects of an existing tower footing ecological restoration technology, in combination withvarious characteristics of mountain tower footing construction, the ecological environment is restored by mixed sowing of cold type plants and tropical and subtropical plants and mixed sowing of herbs and shrubs. The cold type plants sprout and grow in winter and are successfully revived to guarantee water and soil conservation in rainy seasons of late spring and early summer, and the warm plantsincluding the herbs and the shrubs grow and develop after the temperature rises and gradually replace the cold type plants to form final vegetation reconstruction and water and soil conservation.

Description

technical field [0001] The invention relates to an ecological restoration method, in particular to a method for rapid ecological restoration of mountain tower foundations. Background technique [0002] At present, the tower base line in South China gives priority to the maximum use of the actual mountainous terrain. Most of the tower bases initially positioned on the line have slopes, and the excavation of base descending faces the problems of steep slopes in the actual terrain, poor stability of the geological structure, or limited corridor space. Constraints, at the base of the tower with a slope, in order to prevent the impact of rainwater and mountain torrents on the uphill side catchment surface from scouring the base surface, after the main construction of the tower site is completed, ecological restoration should be carried out in time at each slope to reduce the damage of the tower base The soil shear strength and soil cohesion of the section can be improved, so as t...
