Plant composition and method for repairing side slopes of roads in southern high-altitude regions

Abstract

The invention discloses a plant composition and a method for repairing side slopes of roads in southern high-altitude regions, and relates to the technical field of agriculture. The plant compositionfor repairing the side slopes of the roads in the southern high-altitude regions comprises tree and shrub plants, grass flower plants and herbaceous plants. The tree and shrub plants are selected froman optional type or a plurality of optional types of rhus chinensis, cassia glauca, buddleja lindleyana, robinia pseudoacacia, pinus massoniana and hibiscus syriacus; the grass flower plants are selected from an optional type or a plurality of optional types of perennial coreopsis, zinnia elegans, cosmos sulphureus and sanvitalia procumbens; the herbaceous plants are selected from an optional type or a plurality of optional types of lolium perenne, trifolium repens, dactylis glomerata and trifolium pratense. The method for repairing the side slopes of the roads in the southern high-altitude regions includes planting seeds of the plant composition on the side slopes. The plant composition and the method have the advantages that appropriate plant varieties are selected, accordingly, growthand development nodes of the plants can be staggered from one another, and nitrogen, phosphorus, potassium and nutrient competition of the plants can be relieved; seeds of diversified species are sownin a mixed manner, accordingly, intra-species competition and inter-species competition can be reduced, the survival rate of the plants can be increased, and formed landscape effects can be improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, and in particular to a plant combination and a method for repairing road slopes in southern high-altitude areas. Background technique [0002] Road slopes in high-altitude areas in the south generally have relatively large rainfall, and collapsible soils form large gullies. Even after the slopes are protected, there are still many and deep gullies. Generally speaking, protection measures in such areas include: (1) natural regreening of damaged slopes; (2) hard slope protection engineering measures; (3) hanging safety nets for slope protection; (4) single herb plant sowing (5) Hole planting of a single woody plant. [0003] However, the effect of greening restoration on road slopes in high-altitude areas in the south is not ideal, and the natural recovery is slow, and the regreening of plants cannot be achieved at present. After large-scale planting of trees on road slopes in high-altitude...

[0003] However, the effect of greening restoration on the road slopes in high-altitude areas in the south is not ideal, and the natural recovery is slow. At present, the greening of plants cannot be achieved

After large-scale planting of trees on road slopes in high-altitude areas in the south, the survival rate of trees is very low, and the repaired area is easy to degrade, and there are often many bald spots and a large area of ​​bald spots in this area.
