Method for planting Populus euphratica in heavy saline-alkaline land of Gobi desert

Abstract

The invention discloses a method for planting Populus euphratica in a heavy saline-alkaline land of a Gobi desert. The method comprises the steps of: applying 5kg of organic fertilizers in a tree pit during Populus euphratica planting, then putting the roots of the Populus euphratica in water-retaining root-promoting halophilic-basophilic microorganism root dipping solution, planting a Populus euphratica seedling and applying 1000ml of water-retaining root-promoting halophilic-basophilic microorganism root dipping solution around the roots, wherein the water-retaining root-promoting halophilic-basophilic microorganism root dipping solution comprises the following components in parts by weight: one part of halophilic-basophilic microorganism solid bacterial manure for a desert saline-alkaline habitat, one part of sterilization soil, two parts of water, 0.1 part of water retaining agent and 0.002 to 0.005 part of growth hormone. The new method for planting the Populus euphratica in the heavy saline-alkaline land of the Gobi desert has the advantages that the soil salinity and alkalinity can be effectively reduced in a long term, the survival rate of the planted Populus euphratica reaches 100 percent, the growth condition is continuously good and the problem that the survival rate of trees planted in the heavy saline-alkaline land of the arid desert is fundamentally solved.

Description

technical field [0001] The invention relates to a method for planting Populus euphratica in heavy saline-alkali desert Gobi land. Background technique [0002] In recent years, with the interference of human economic and social activities and the intensification of natural disasters, the ecological environment in the Gobi desert in Northwest my country has continued to deteriorate. The dry climate, barren soil and heavy salinity have greatly reduced the vegetation coverage. In order to further prevent the deterioration of the ecological environment, my country has carried out a large-scale afforestation project in the arid desert heavy saline-alkaline area of ​​Northwest China. The low survival rate of the planted trees not only has no meaning for improving the ecological environment, but also causes a waste of human and material resources. In order to improve this situation, it is necessary to vigorously select excellent tree species that are excellent, cold-resistant, earl...

AI Technical Summary

Problems solved by technology

In the past, because there was no scientific and accurate understanding and grasp of the rules of planting and afforestation of this tree species in the desert Gobi heavy saline land, the afforestation work of Populus euphratica was very difficult. This situation has long plagued the scientific community and forestry workers, and it is also a worldwide problem.
