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

Embodiment

[0043] Example Limestone slope greening of an expressway

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

[0045] 2) Soak the seeds of the red-backed mountain hemp stalk with 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, keep drenching water to moisten the soil;

[0046] 3) About 16 days after sowing, the seeds start to germinate. When the seedlings are 6-8cm high, 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) Put the red-backe...

Abstract

The invention discloses a method for greening a limestone slope. According to the method for greening the limestone slope, the slope is refilled with soil removed from other places, then bermuda grass, alchornea trewioides and pigeon peas are planted for greening the slope, and the method has the advantages that the success rate of greening is high, operation is easy and convenient, popularization and application are easy, and the greening effect is good. One year after the plants are planted, the plants can cover the limestone slope of a highway in mountain areas, the ecological and landscape effects of greening can be achieved rapidly, not only noise but also flying dust can be absorbed, and special care is not needed in the later period. The method can be widely applied to greening of the slope of the highway in the mountain areas, can also be used for greening limestone mountains where stone is taken, and has very good application prospects.

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 1300,000 km 2 , accounting for about one-seventh of the country's total area; buried carbonate rocks cover an area of ​​about 700,000 km 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 ...
