South Xinjiang sand drought-resisting sand-fixating forestation method

Abstract

The invention provides a South Xinjiang sand drought-resisting sand-fixating forestation method. The method includes the following steps: 1) soil preparation of a forestation land; 2) selection of the forestation time; 3) preparation of nursery stocks; 4) treatment of the nursery stocks before planting; 5) production of auxiliary protection devices: self-produced tubular protection devices are made of PVC plastic tubes or hardboards, the tube diameter is 90-110 mm, the wall thickness is 2.7-3.2 mm, and the length is 30-40 cm; and the tubular protection devices may be produced by binding reed, wheat straw or waste cotton stems in a forestation land with low wind erosion and sand-burying level; 6) planting and protection of the forestation land: the depth of underground parts of the tubular protection devices cannot exceed that of underground parts of the nursery stocks or shoots, over-ground parts of the tubular protection devices are 15-20 cm higher than a ground surface, and the height of over-ground parts of the nursery stocks or the shoots is higher than the height of the over-ground parts of the tubular protection devices; and 7) seedling management after forestation. The beneficial effects of the method are that the forestation method is scientific, reasonable, low in cost, and is easy to promote and apply.

Description

technical field [0001] The invention belongs to the technical field of desertification prevention and control, and in particular relates to a drought-resistant and sand-fixing afforestation method in the sandy land of southern Xinjiang. Background technique [0002] In southern Xinjiang, there is the Taklamakan Desert, the largest desert in my country. The oasis land resources that can be developed and utilized by local people in the region are very limited. Therefore, in the development and utilization of oasis sandy land, a key problem that must be solved is the construction of protective forests. With protective forests On this basis, the protection of oasis land can be developed for agricultural production and other activities. Without the protection of shelter forests, it will be more seriously harmed by meteorological factors such as wind, sand and high temperature. [0003] A key technology in the construction of shelterbelts is to ensure the survival rate of seedling...

AI Technical Summary

Problems solved by technology

For the newly developed sandy land on the edge of the desert, the terrain is undulating, and the wind and sand activities are frequent. For the cutting afforestation of ordinary short cuttings, it is difficult to supply water. Under the condition of water saving, drip irrigation is often used to supply water. Therefore, it cannot To meet the needs of drought resistance and high temperature resistance of saplings, the survival rate of saplings is low
