Problems solved by technology

After adopting engineering protection measures for the slope, it is difficult for the destroyed vegetation to recover quickly due to the lack of an environment for plant growth.
However, these structures often affect the appearance of the road and increase the radiant heat during the high temperature season in summer.
[0004] In addition, the mining of limestone will also form slopes, and improper restoration will also damage the ecological environment

[0043] Example Limestone slope greening of an expressway

[0044] 1) Prepare the seedbed in advance, level the seedbed, with a strip distance of 20cm, a banner width of 8cm, and a ditch depth of 5cm;

[0045]2) Soak the seeds of the red-backed mountain hemp stalk in 30°C normal temperature water for 4 hours, filter the water, take out the seeds and sow them on the seedbed, sow 50-60g per square meter, cover with soil about 1cm after sowing, cover with straw, and keep it dry. water to moisten the soil;

[0046] 3) About 16 days after sowing, the seeds begin to germinate, and when the height of the seedlings is 6-8 cm, remove them and transfer them to a nutrition bag. K) 0.25kg, cultivated under a shade net with a light transmittance of 70%, and strengthen watering management;

[0047] 4) On the limestone slope, artificially backfill foreign soil with a thickness of at least 10cm. The foreign soil is the surface soil retained during the excavation of the slope;

[0048] 5) ...

Abstract

The invention discloses a greening method for a limestone slope. The method of the invention backfills the side slope with foreign soil, and then plants bermudagrass, red-backed gooseberry and pigeonpea to green the side slope, and has the advantages of high greening success rate, simple operation, easy popularization and application, excellent greening effect and the like. Planting for one year can cover the side slopes of highways in limestone mountainous areas. It can quickly achieve the ecological and landscape effects of greening. It can not only absorb noise, but also absorb flying dust, and no special care is required in the later stage. It can be widely used on the sides of highways in limestone mountainous areas. The greening of slopes can also be used for regreening after stone extraction from limestone mountains, and has a very good application prospect.

Description

technical field [0001] The invention relates to an environment restoration method, in particular to a greening method for limestone slopes. Background technique [0002] Limestone areas are widely distributed in China. According to incomplete statistics, the total area is 2,000,000km 2 , of which the exposed carbonate rock covers an area of ​​about 1300,000km 2 , accounting for about one-seventh of the total area of ​​the country; the buried carbonate rock area is about 700,000km 2 . Carbonate rocks are distributed in all provinces and autonomous regions of the country, with the widest distribution in Guangxi, Guizhou and eastern Yunnan. In western Hunan, western Hubei, eastern Sichuan, Shandong, Jin and other places, carbonate rocks are also widely distributed. [0003] With the acceleration of expressway construction in our country, when the expressway passes through limestone areas, especially limestone mountainous areas, sometimes large excavation of the mountain is ...
