Embodiment 1

[0037] The present invention is in representative arid region——Maoxian County, the center section of the arid valley in the upper reaches of the Minjiang River, such as figure 1 As shown in the figure, native plants are planted on the road slope in this area, and a mosaic vegetation structure is configured.

[0038] Mosaic plant community configuration model and slope protection vegetation planting method in arid area:

[0039] (1) Seed acquisition and storage: Select plants with vigorous growth, no pests and diseases, and strong branches to harvest seeds. The small seeds were selected by hand, and the large seeds were selected by water to obtain plump seeds, which were placed in a ventilated and dry environment to dry, packed in dry cloth bags, and stored in a refrigerator at 4°C.

[0040] (2) Slope matrix treatment: select a road slope with a width of 12m, a slope of about 50°, and a volume percentage of gravel in the soil of 33% mixed with soil and rock, with an area of ​​...

Embodiment 2

[0046] (1) Seed acquisition and storage: Select plants with vigorous growth, no pests and diseases, and strong branches to harvest seeds. The small seeds were selected by hand, and the large seeds were selected by water to obtain plump seeds, which were placed in a ventilated and dry environment to dry, packed in dry cloth bags, and stored in a refrigerator at 4°C.

[0047] (2) Slope matrix treatment: select a road slope with a width of 7.8m, a slope of about 43°, and a volume percentage of gravel in the soil of 37% mixed with soil and rock, with an area of ​​86m 2 . Level the slope. Select the 0-20cm soil under the forest, the total organic carbon content is 17.1g kg -1 , pH 5.5, bulk density 1g cm -3 , total nitrogen 2.6g·kg -1 , available phosphorus 8.4mg·kg -1 , available potassium 89mg·kg -1 . Add humus to the slope soil of 0-20cm soil layer according to the ratio of humus: slope soil of 1:5, mix evenly, and carry out 3 parallel experiments.

[0048] (3) Sowing: I...

Abstract

The invention belongs to the field of ecological treatment, and particularly discloses a plant community configuration model and a slope protection vegetation planting method by utilizing native shrubs and grasses in an arid area. On the basis of mastering natural conditions of the arid area, substrate conditions of road slope and local ecological characteristics, and correctly identifying key factors restricting planting of plants on the slope, a configuration model is established through matching planting of different species, and substrate environment is manually regulated and controlled bycombining the slope protection vegetation planting method, so that the planting of local plants on the slope of the arid area is promoted, a stable vegetation structure is constructed, coverage of grass vegetation on the slope is improved, and soil and water loss is slowed down. The model and the method can solve problems of serious environmental factors in arid areas, difficult vegetation restoration, and hidden ecological safety hazards caused by introduction of a large number of foreign species on a side slope.

Description

technical field [0001] The invention relates to the field of ecological management, in particular to a mosaic plant community configuration model in an arid area and a planting method for slope protection vegetation. Background technique [0002] In recent years, the development of road transportation has produced a large area of ​​slopes. The exposed surface, soft soil and high soil gravel content are the main reasons for road soil erosion. Slope vegetation restoration and reconstruction are important measures to prevent slope soil erosion. In slope vegetation restoration, according to the regional arid climate characteristics and slope substrate conditions, select and configure appropriate plant species, establish a complete plant community, maintain the continuous stability of slope vegetation structure and function, reduce input costs as much as possible, increase The ecological and economic effect is the key to the restoration of road slope vegetation. [0003] The ma...
