Embodiment

[0023] The present invention has been tested and demonstrated in the construction of the water-saving biological protection system on the periphery of the Cele Oasis and the Pishan Oasis on the southern edge of the Taklamakan Desert: the specific operations are carried out in the following steps:

[0024] Natural shrub-herb restoration area construction:

[0025] a. Restoring and repairing the original irregularly distributed tamarisk 5, camel thorn 6, flower firewood 7, and some short-lived plants halophytes or pig hairy vegetables to form the first protection zone 1 of the biological protection system, and the protection zone 1 The length and width are 300 meters x 50 meters;

[0026]Construction of artificial arbor-grass planting area:

[0027] b. After the first protection zone 1, the small block 8 planting mode is adopted, and the arbor Xinjiang poplar and the forage big-leaf alfalfa are planted. The area length and width of the small block 8 are 10 meters × 5 meters, an...

Abstract

The invention relates to a method for construction of a water-saving biological protection system on the periphery of an oasis under flood irrigation condition. According to the method, tamarix chinensis, alhagi sparsifolia, karelinia caspia and certain ephemeral plants such as halogeton or salsola collina which are originally distributed irregularly are restored and repaired to form a first protection zone; populus bolleana of tree category and big-leaf clover of forage category are planted in a cell block mode to form a second protection zone; an artificial biological isolation zone is set with fraxinus mandshurica planted in trenches and subject to furrow irrigation to form a third protection zone; and forests of black walnuts of tree category and medical herbs are planted with combination of trench planting and block planting to form a fourth protection zone. By adopting the method, the allocation of deep-rooted plants and shallow-rooted plants, the allocation of trees, shrubs and herbaceous plants, the allocation of sun plants and shade-tolerant plants and the allocation of protective plants and economic plants are demonstrated in a centralized way in the biological protection system, effective utilization of water by plants can be realized, and normal rapid growth of plants can be ensured.

Description

technical field [0001] The invention relates to a technical method for constructing a water-saving biological protection system around an oasis under flood irrigation conditions. The popularization and application of the technology will provide technical support for the construction of a water-saving biological protection system around an oasis in an arid area. So as to provide a technical approach for the coordinated development of ecological construction and ecological industry in arid areas. Background technique [0002] The southern margin of the Tarim Basin is one of the regions with the harshest ecological environment and the most concentrated distribution of national-level poverty-stricken counties in my country. Here belongs to the typical inland warm temperate desert climate, and its main environmental characteristics are: ①Frequent wind and sand disasters. The number of days with a wind speed greater than 4m / s is more than 90 days per year, the annual average floa...
