Embodiment 1

[0035] In the above-mentioned sandstorm area in Weichang, Hebei, the overall width of the planting vegetation belt is 20m, and the land is prepared in the form of ridges in autumn one year before planting, and the soil is sprinkled with water after the preparation; °, such as figure 1 and figure 2 As shown, the strip-shaped ridge back formed by undisturbed soil or compacted soil; furrows are set on both sides adjacent to the ridge back, and the ridge is 30cm lower than the ridge back; the width of ridge B is 40cm, and the width of ridge back A is 60cm, and the original shape is used in the ridge Cultivate the soil, cover the plants with 2cm of farmyard manure before planting; plant Shadawang in the furrows; arrange the furrows and the back of the furrows alternately. Satawang is sown in mid-May, and the plant height of that year can reach 35.43cm. At the same time, in the same area, the land preparation and flat ground are planted with sand and sand, and the row spacing, pl...

Embodiment 2

[0038] In the above-mentioned windy and sandy area of ​​Hebei Weichang, the ridge-shaped soil was prepared in autumn one year before planting, and the soil was sprinkled with water after the soil preparation; figure 1 and figure 2 As shown, the back of the ridge formed by undisturbed soil or compacted soil; furrows are set on both sides adjacent to the back of the ridge, and the furrow is 20 cm lower than the back of the ridge; the width of ridge B is 40 cm, and the width of ridge back A is 60 cm. Soil, covered with 2cm of farmyard manure before planting; in the furrows, mixed brome and wheatgrass were sown; furrows and ridge backs were arranged alternately; brome and wheatgrass were sown in mid-May, and the plant height of the year was It can reach 23.45cm and 25.86cm. At the same time, in the same area, brome and wheatgrass are planted on the ground. The row spacing, plant spacing, agricultural management, watering and fertilization are the same as above.

Abstract

The invention discloses a vegetation planting method in windy and sandy areas. According to the method, ditching and ridging are carried out in the windy and sandy areas for planting in a stripe field; ridge backs formed by undisturbed soil or compacted soil are included; strip furrows are arranged on two adjacent sides of the ridge backs, and the furrows are 20 cm-30 cm lower than ridge backs; vegetation is planted in the furrows; the width proportion of the furrows to the ridge backs is 2:(1-4), and the furrows and the ridge backs are arranged alternately; and the directions of the furrows and the ridge backs are consistent and form an included angle of 60-90 degree with a prevailing wind direction. The invention provides a vegetation recovery and reconstruction technical method for thewindy and sandy areas and can also be used for agricultural cultivation in the windy and sandy areas, a planting mode of land preparation in a wide range in existing vegetation recovery or reconstruction in the windy and sandy areas, wind erosion can be controlled to the maximum extent, the furrows are arranged to converge runoff to provide the good growth microenvironment for vegetation, the ridge backs are arranged to protect the current surface to the maximum extent due to arrangement of the ridge backs, reduce disturbance and intercept windy sand substances, and a good technical method isprovided for vegetation planting in the windy and sandy areas.

Description

technical field [0001] The invention relates to soil improvement in a sandy land, in particular to a technical method for vegetation restoration and reconstruction in a sandstorm area. Background technique [0002] In recent years, with the advancement of the national ecological civilization strategy, especially the full implementation of the policy of returning farmland to forests and the closure of sandy areas, the governance of sandy areas in my country has achieved remarkable results. However, my country's arid and semi-arid areas have a large area and a wide distribution range. Due to climate change and irrational use by humans, some windy and sandy areas and interlaced areas of agriculture and animal husbandry are facing enormous pressure from soil degradation and vegetation restoration and reconstruction. Therefore, it is of great significance to study the methods suitable for vegetation construction in windy and sandy areas to improve the living environment, promote ...
