Grassland restoration ecological bag and application thereof

Abstract

The invention discloses a grassland restoration ecological bag and application thereof. The grassland restoration ecological bag comprises a ecological bag main body and seeds and a mixed substrate filled in the ecological bag main body, wherein the mixed substrate is a mixture prepared from soil, organic matters, a slow release fertilizer and grass powder according to the mass ratio of (65 to 70):(5 to 15):(5 to 10):(15 to 20); the mass ratio of the seeds to the mixed substrate is (2 to 3):(100 to 150). The substrates filled in the ecological bag main body can be conveniently collected; cow and sheep dung is used as organic matters and are used for providing nutrients for the plant growth together with the slow release fertilizer; particularly, withered grass ground powder filled in the ecological bag main body can further enhance the water holding performance of the substrate; the substrate and the seeds are put into the grassland restoration ecological bag; the seed flying and the damage can be prevented; the seed germination rate and the young seedling survival rate can be improved; a later stage plateau ecological bag main body material of non-woven fabric can be degraded. Thegrassland restoration ecological bag is particularly applicable to heavy-degraded high-cold 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...

AI Technical Summary

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
