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...
