Imitative ecological afforestation method for Haloxylon ammodendron in desert area of sandstorm front

The invention discloses an imitative ecological afforestation method for Haloxylon ammodendron in a desert area of a sandstorm front, belonging to the technical field of plant cultivation. Desert land with a soil water content of 2% and above and a saline-alkali degree of less than 2% is selected as afforestation land. Cultivation belts are dug out along the eastwest trend of the afforestation land before the soil defreezing and plantation. In the cultivation belts, heeling-in ditches for heeling in are dug along the eastwest trend. Then direct-seeding forestation, irrigation, pest control, and enclosing management and protection are successively applied. Cultivation belts are dug out before plantation and afforestation, so that low survival rate and growth rate of Haloxylon ammodendron caused by the fact that weeds compete with Haloxylon ammodendron for water and fertilizer are avoided. At the same time, the original ecology is maintained by keeping certain space between every two cultivation belts and damage to local ecological environments can be prevented. Demands for water during plantation of Haloxylon ammodendron are sustained by the construction of reservoirs. Thus, the transplanting survival rate of Haloxylon ammodendron is remarkably increased to 90% and above in comparison with the traditional transplanting survival rate of about 10%.
