[0044] Step 3. Drill holes at the points drilled in step 2. The hole depth is 0.3m, the hole diameter is 0.12m, the hole spacing is 0.5m, and the angle between the hole and the slope is 85°;

[0045] Step 4. Apply 10g of urea in the hole made in step 3. The urea is Huaerkang brand quick-acting nitrogen fertilizer, then backfill the planting soil with a thickness of 15cm, and then place a nutrition bowl. The inner diameter of the nutrition bowl is 0.18m and the height is 0.15m. ;

[0046] Step 5. Place the nutrient pot seedlings bred on the seedbed in advance in the nutrient pot, place 1 nutrient pot seedling in each nutrient pot, and the seedling diameter of the nutrient pot seedlings is 0.2m. The coveri...

Embodiment 2

[0055] Step 1. Select a slope with a slope ratio of 1:1.5 for slope erection;

[0056] Step 2. Stand on the frame set up in step 1 to do the slope planting holes. The slope greening planting holes are arranged in a plum blossom shape, and the dot density is 12 holes / m 2 ;

[0057] Step 3. Drill holes at the points drilled in step 2. The hole depth is 0.35m, the hole diameter is 0.1m, the hole spacing is 0.45m, and the angle between the hole and the slope is 90°;

[0058] Step 4, apply 15g of urea in the hole made in step 3, then backfill the planting soil with a thickness of 10cm, and then place the nutrition bowl, the inner diameter of the nutrition bowl is 0.08m, and the height is 0.25m;

[0059] Step 5. Place the nutrient pot seedlings bred on the seedbed in advance in the nutrient pot. Place 3 nutrient pot seedlings in each nutrient pot. The seedling diameter of the nutrient pot seedlings is 0.15m. After the nutrient pot seedlings are placed, The covering thickness is 2c...

Embodiment 3

[0068] Step 1. Select a slope with a slope ratio of 1:1.0 for slope erection;

[0069] Step 2. Stand on the frame set up in step 1 to do the slope planting holes. The slope greening planting holes are arranged in a plum blossom shape, and the dot density is 16 holes / m 2 ;

[0070] Step 3. Drill holes at the points drilled in step 2. The hole depth is 0.32m, the hole diameter is 0.11m, the hole spacing is 0.48m, and the angle between the hole and the slope is 88°;

[0071] Step 4. Apply 13g of urea in the hole made in step 3, then backfill the planting soil with a thickness of 13cm, and then place a nutrition bowl. The inner diameter of the nutrition bowl is 0.13m and the height is 0.20m;

[0072] Step 5. Place the nutrient pot seedlings bred on the seedbed in advance in the nutrient pot. Place 2 nutrient pot seedlings in each nutrient pot. The seedling diameter of the nutrient pot seedlings is 0.18m. After the nutrient pot seedlings are placed, The nutrient soil covering thi...

Abstract

The invention discloses an ecological protection method of a road slope. The ecological protection method comprises the steps of firstly, selecting a slope having the slope ratio of 1: (0.75-1.5) and putting up a support on the slop, dotting planting holes by standing on the put-up support in the dotting density of 9 holes / m2, 12 holes / m2 or 16 holes / m2 and arranging slope greening planting holes in quincunx, secondly, drilling the holes at the depth of 0.3m-0.35m, the diameter of 0.1m-0.12m, the pitch of holes of 0.45m-0.5m and the angle between each hole and the slope of 85-90 degrees, applying 10g-15g of urea to each drilled hole, backfilling planting soil at the thickness of 10cm-15cm and then placing nutrition pots, and finally, putting nutrition pot seedlings grown on a seedbed in advance into the nutrition pots, 1-3 seedlings in each nutrition pot, and covering nutrient soil at the thickness of 2cm-3cm after the nutrition pot seedlings are placed completely. The ecological protection method of the road slope succeeds in solving the problems of water and soil loss, heavy soil damage and high maintenance cost in the existing road slope protection technology.

Description

technical field [0001] The invention belongs to the technical field of road slope protection, and in particular relates to a method for ecological protection of road slopes. Background technique [0002] With the vigorous construction of high-grade highways in mountainous areas, the original topography and soil profile structure have been changed, and the ecological protection of highway slopes has attracted increasing attention. The ecological environment in mountainous areas is fragile, especially for arid and semi-arid areas. How to strengthen the vegetation restoration of road slopes in mountainous areas is one of the main contents of ecological environment restoration and development in ecologically fragile areas. [0003] Among the common highway slope protection technologies are three-dimensional vegetation net slope protection, hanging net soil spraying slope protection, thick layer substrate spraying technology and geocell grass planting slope protection, etc. Howe...
