Description

A shrub planting method and seedling protection cover for slope protection

technical field

The invention relates to the field of slope engineering protection and ecological restoration, in particular to high and steep rock excavation slopes, and in particular to a method for planting shrubs in slope protection and a seedling protection cover used in the method.

Background technique

During the construction of infrastructure such as roads, railways, water conservancy, and mines, a large number of exposed slopes are left by excavation, filling, and spoils, accompanied by obvious soil erosion and small landslides. The method of growing plants on slopes has made some progress in enhancing the stability of slopes, reducing soil erosion and improving landscape effects. In order to achieve a permanent slope ecological restoration effect, the advantages of plants should be combined, and shrubs and herbaceous plants should be planted together, so as to better stabilize the slope and take into account the ecological landscape effect, while promoting the positive succession of the plant community instead of Human intervention is required. The spray-mixed planting technology is currently widely used and recognized as a good slope protection and ecological restoration method, but there are still the following deficiencies.

First, because shrub seeds generally have varying degrees of hardness, they are in a hard and dense state for a long time under appropriate water and heat conditions, and do not absorb water, swell, or germinate. Although the germination rate of treated seeds has increased, But it is far from reaching a relatively high germination rate. At the same time, the cement added to improve the strength of the base material in some constructions has a significant inhibitory effect on the germination and initial growth of shrub seeds. At present, the methods of planting shrubs in slope ecological restoration are often mixed with herbaceous seeds during construction, cuttings and transplanting shrub seedlings on the slope after construction, but the survival rate of shrubs in these methods is extremely low. Although the germination and growth of shrubs on the slope have been improved by using techniques such as planting bags, there are still some seeds that do not germinate, especially when the germination rate is reduced when encountering bad weather.

Second, after shrubs and herbaceous plants are mixed seedlings, the shrubs are at a disadvantage in the early growth stage and the interspecific competition of herbaceous plants due to their slow growth, often showing poor growth, slow growth, and easy death.

Third, after restoration by spraying base material on high and steep rock slopes, the frictional resistance between the slopes is not large, and the bonding force between the base material layer and the slope surface is not enough, and the two are not integrated. Delamination of the substrate layer may occur during weather conditions.

Contents of the invention

The object of the present invention is to solve the above problems, and provide a shrub planting method in slope protection and a seedling protection cover thereof, which can improve the survival rate of shrub plants and at the same time enhance the stability of the base material.

In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a method for planting shrubs in slope protection, the specific steps are:

1) Raising shrub seedlings with seedling bags to obtain shrub seedlings;

2) Drill holes on the slope surface according to the design requirements of the shrub layout and the size of the seedling bag, then move the shrub seedlings together with the seedling bag into the hole, and fill and fix them. Install seedling protection covers on the seedling bags and shrub seedlings, and finally spray the base material on the slope surface, remove the seedling protection cover after spraying, and maintain the slope surface;

Through the above construction, the shrub planting in slope protection is completed.

The present invention grows seedlings in the degradable seedling-growing bags, and after the shrub seedlings grow to a certain extent, the seedlings together with the seedling-growing bags are transplanted into the holes on the slope to fill and fix them before spraying the base material, and they are protected with a seedling protection cover. Then spray the base material, so that the shrubs can grow normally on the slope, and realize the vegetation slope protection mode in which the herbs and shrubs are mixed and planted synchronously.

The seedling-raising bag is a degradable seedling-raising bag, breathable and water-permeable, low in cost, self-degradable in soil and harmless to the environment; the size of the seedling-raising bag is determined according to the development degree of the root system of the shrub plant species to be cultivated, but its length is not less than 30cm; the seedlings are in a cylindrical shape after being packed with soil; at least 10cm of the slope should be exposed when implanted into the drill hole.

When drilling on the slope surface, the depth of the hole is slightly smaller than the height of the seedling bag, but not less than 20cm; the diameter of the hole is slightly larger than the diameter of the seedling bag, and the angle between the hole and the upslope is ≥ 90 degrees.

When drilling holes on the slope surface, the places with cracks on the slope surface should be selected first, which will help the roots of shrubs to grow in the cracks.

When spraying the base material on the slope surface, first spray the 8-9cm base material layer, and then spray the 1-2cm surface layer containing herb seeds on the base layer, which can realize the simultaneous construction of shrubs and herb plants plant.

The shrub seedlings are drilled and transplanted when the height reaches 10-30 cm, and the survival rate of the seedlings is higher at this time.

The seedling protection cover includes a cylinder in the middle, a cone with a bottom and the same diameter is connected above the cylinder, a handle is installed above the cone, and a plurality of fixing rods are installed below the cylinder. The diameter of the cylinder is between the seedling bag and the hole, which protects the seedlings in the space inside the cylinder while spraying the substrate. The design of its conical top allows the material to be sprayed onto the slope when spraying the substrate without accumulating on the top of the seedling protection hood.

The bottom of the cylinder of the seedling protection cover is at least 8cm away from the slope, which is convenient for the spray substrate and the seedling bag to be tightly bonded into one.

The seedling protection cover for shrub planting using the above method includes a cylinder in the middle, a cone with the same diameter as the bottom is connected above the cylinder, a handle is installed above the cone, and a plurality of fixing rods are installed below the cylinder .

The cylinder and the cone are integrally arranged, and the handle is T-shaped, which is convenient for lifting and taking away.

The fixing rod is a hard rod with a length of 20-30cm and a diameter of 5-15mm. So that the seedling cover can be stabilized on the slope and withstand the impact of the substrate when spraying.

The present invention has the following advantages and beneficial effects:

1. The present invention can directly raise seedlings in seedling bags on flat ground, and the bag is filled with seedling soil that is beneficial to seed germination and growth or cuttings survival. The implementation is simple and the management is convenient.

2. The present invention directly transplants the shrub seedlings to the slope, sprays the base material again, and realizes the synchronous planting of herbaceous plants and shrub plants through the application of the seedling protection cover at the same time, and the transplanted seedlings can make the grass and shrubs grow on the slope. The survival rate of the shrubs is greatly improved, which solves the problems that the seeds do not germinate and the cuttings rot and die after sowing or cutting on the slope.

3. When the present invention is transplanted, it is moved into the hole on the slope together with the seedling soil, which avoids the phenomenon of dead seedlings and diseased seedlings caused by damage to the root system and changes in the rhizosphere microenvironment when the seedlings are transplanted by conventional methods, and also avoids spraying when used. Disturbance damage to habitat substrate after shrub establishment.

4. The present invention selects shrub seedlings that grow vigorously after seedlings to be transplanted, so that shrub seedlings avoid interspecific competition with herbaceous plants, and speed up the process of grass-shrub mixed coverage on slopes.

5. The present invention drills holes on the slope and transplants shrubs so that the substrate layer and the slope form a mosaic, the drilling increases the growth space for the roots of the shrubs, and makes the substrate layer and the slope form an anti-slide pile structure, making the slope Ecological protection is more stable.

6. The seedling raising bag used in the present invention is made of degradable materials, which is cheap and harmless to the environment; the seedling protection cover used is simple in structure, easy to manufacture and reusable, and has high application value.
