Problems solved by technology

After actual inspection, it can be found that most of the materials in the ecological bags are not filled enough, resulting in loose bags and serious displacement, which makes the originally designed slope ratio impossible to achieve.
Because the stitching of the ecological bag after filling is not meticulous and the quality of the suture is poor, the mouth of the ecological bag is cracked; the foundation of the ecological bag slope protection has not been handled well, resulting in the growth of ecological vegetation, and the connection between the ecological bag and the original foundation has not been strengthened. has been deformed
[0004] Severely degraded alpine grasslands are more severely degraded, and they can be directly re-sowed with pasture seeds to restore them, but the seeds are too light, and the alpine grasslands are relatively windy, easy to float; and the local evaporation is fast, if it does not rain after sowing, the seeds will lose water quickly dries out, germination rate is very low

Embodiment 1

[0019] The preparation of grassland restoration ecological bag comprises the following steps:

[0020] (1) Mix soil, organic matter, slow-release fertilizer, and grass powder in a mass ratio of 70:10:5:15 to obtain a mixed substrate; the organic matter is cattle and sheep manure, and the grass powder is local hay powder.

[0021] (2) Evenly mix the seeds of Elypa tachycarpa and the mixed substrate according to the mass ratio of 3:100, wherein the purity of the seeds is above 95%, and the germination rate is above 85%.

[0022] (3) Put the matrix mixed with seeds into the ecological bag, the size of the ecological bag is 80cm in length, 5cm in diameter, and 1570cm in capacity 3 . One side of the ecological bag is sealed, and the other side is opened, and a long rod funnel is used to fill the 1000cm 3 The substrate and seed mixture are used to ensure a certain space in the ecological bag, and then sealed with a sealing machine.

Embodiment 2

[0024] (1) Greenhouse test

[0025] The temperature in the greenhouse is 15°C-30°C, and the relative humidity is 70%-80%.

[0026] Example 1 Grassland Restoration Ecological bags were placed in parallel in the greenhouse at a distance of 15 cm.

[0027] The seeds of Elymus chinensis were sown in the greenhouse with a row spacing of 15 cm by conventional sowing methods.

[0028] The emergence rate of grassland recovery ecological bags and conventional sowing methods were both stable above 85%, and the emergence of ecological bags was slightly earlier.

[0029] (2) Community test

[0030] The plot test was carried out on the campus of China Agricultural University (Beijing), under natural conditions in June, the temperature was 15°C-25°C, and the humidity was 50%-60%.

[0031] Example 1 Grassland Restoration Ecological bags are placed in parallel in the plot at a distance of 15 cm.

[0032] Adopt conventional sowing method to sow the seeds of Elymus chinensis in the plot at ...

Abstract

The invention discloses a grassland restoration ecological bag and an application thereof. The grassland restoration ecological bag includes the main body of the ecological bag, and the seeds and the mixed substrate filled in the main body of the ecological bag; the mixed substrate has a mass ratio of (65-70):(5-15):(5-10):(15-20 ), the mixture of soil, organic matter, slow-release fertilizer and grass powder, the mass ratio of seeds and mixed substrate is (2-3):(100-150). The matrix filled in the main body of the ecological bag of the present invention is convenient to collect, and the manure of cattle and sheep is used as an organic matter, which provides nutrients for plant growth together with the slow-release fertilizer; especially the dry grass powder filled in the main body of the ecological bag can further enhance the water retention of the matrix The substrate and seeds are placed in the grassland restoration ecological bag to prevent the seeds from flying away and being destroyed, and can improve the germination rate of the seeds and the survival rate of the seedlings; the non-woven fabric of the main material of the plateau ecological bag in the later stage can be degraded; the grassland restoration ecological bag of the present invention is especially suitable for Severely degraded alpine grassland.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a grassland restoration ecological bag and its application. Background technique [0002] Ecological bag slope protection technology, the application principle of ecological bag slope protection is as follows: put soil in the ecological bag, wrap it with cable ties or wires, and form an ecological retaining wall through orderly placement. On the one hand, it can be used for greening and beautifying through vegetation. The role of the environment; on the other hand, it can play the role of slope protection, and can be used for slope protection, river embankment protection, mine restoration, highway slope protection, ecological river bank slope protection, etc. Lawn Vegetation Tape technology is a product formed by using two layers of special non-woven fabric as a carrier, placing high-quality grass seeds in it, applying a certain amount of fertilizer, an...
