Problems solved by technology

[0009] The purpose of the present invention is to provide a method for afforestation of Haloxylon-free vegetation in heavy clay soils in arid regions, aiming at the difficulty in restoring vegetation in heavy clay soils in the current arid regions and the high maintenance cost. In large-scale practice, artificial water collection tanks are built through terrain transformation combined with planting holes to plant substrates to replace sand to collect natural precipitation. Use water to prevent excessive water collection on the surface and ensure the normal growth of plants

Embodiment 1

[0031] In 2012, a test area (N45) was set up in the southern heavy clay area of ​​Karamay Petrochemical Industrial Park o 19'28''E85 o 03′07′′), the test area chose the engineering trench section formed by bulldozers bulldozing from both sides of the road when constructing the road foundation. The engineering trench is perpendicular to the road. Planting Haloxylon in the last ten days:

[0032] Terrain arrangement: select the 5 m wide engineering trench terrain formed during the construction of the highway subgrade, and organize it into a water collection tank in the engineering trench section. The slope 1 of the edge of the ridge 5 is 40°, the length of the water collection tank is 25m, and the planting hole is excavated at the bottom 2 of the groove. The distance between adjacent planting rows at the edge of the tank is 3m. At the bottom of the tank 2 vertical and parallel to the direction of the water collection tank, a 20cm high water retaining soil ridge 4 is made ...

Embodiment 2

[0039] In 2014, in the heavy clay area in the southern part of Karamay Petrochemical Industrial Park, the construction area of ​​the desert-free vegetation restoration project was 280 mu (N45 o 19'32'', E85 o 03′10′′), the survival rate reached 85%. In October 2013, the topography was adjusted, and the planting holes were dug to plant the substrate to replace the sand. In March 2014, Haloxylon was planted:

[0040] Terrain arrangement: arrange the terrain into a 5 m wide water collection tank, the bottom of the water collection tank is 3 m wide, the height of the trough water collection soil ridge 5 is 0.9m, the edge slope 1 of the trough water collection soil ridge 5 is 40°, the length of the water collection tank is 50m, Bottom 2 excavated planting holes with a diameter of 50cm and a depth of 70cm. The row spacing between plants was 2m×2-3m. At the bottom of the groove 2, perpendicular to the direction of the water collection tank, a 20cm high water retaining soil ridge 4 i...

Abstract

The invention relates to an unirrigated vegetation planting method by Haloxylonammodendron for heavy clay lands of an arid area. The method includes the steps of land preparation, sand changing for planting pits, seedling quality determining, planting and managing; according to three-year experimental study and large-scale practice, natural rainfall is collected by building of artificial catch basins with sand changing for culture substrate of planting pits; owing to ease of seepage, good water retention and low evaporation in sandy soil, effective available moisture is provided; excess surface water accumulation is prevented, and normal growth of plants is guaranteed. The novel method is provided for unirrigated vegetation recovery by Haloxylonammodendron for the heavy clay lands of the arid area, and the problems that current vegetation recovery for the heavy clay lands of the arid area is difficult and maintenance cost is high are solved.

Description

technical field [0001] The invention belongs to the technique of restoring desert vegetation in arid areas, and in particular relates to a method for restoring and rebuilding vegetation in Haloxylon artificial forests under the condition of heavy clay soil in the arid areas. Background technique [0002] Haloxylon ( Haloxylon ammodendrom (C.A.Mey.) Bunge) loamy deserts are distributed on the Quaternary ancient alluvial plains. The coverage of Haloxylon loamy desert communities is less than 10%. The living environment of vegetation is extremely fragile. The soil is desert lime-calcium soil or cracked soil. Cracked soil is heavy in texture and formed by deposition in alluvial or alluvial plains beside rivers and lakes, and the heavy soil layer has poor air permeability. There are about 600,000 hectares of heavy clay soil in the north of the Tianshan Mountains. This kind of heavy clay soil is heavy in texture and weak in permeability. Occasional precipitation is often removed...
