Abstract

The invention relates to a method for planting apocynum venetum in a salinized desert of an arid region. The method comprises the following steps of: opening a parallel ditch in a salinized soil environment; paving a drip irrigation zone at the bottom of the ditch; carrying out salt elution on the soil in the ditch; and then sowing apocynum venetum seeds at the bottom of the ditch. According to the method, a water-saving drip irrigation technology is used for eluting salt of the soil; a principle that the sale moves toward the high part is combined to create a low-salt environment of seed germination and seedling growth in the salinized desert, so as to realize seedling planting; and the method overcomes the disadvantages of seedling transplantation of the apocynum venetum and the large-scale planting of the apocynum venetum is realized, so as to accumulate technical reserve for development and utilization of a large-area saline-alkali soil wasteland of the arid region.

Description

technical field [0001] The invention belongs to the field of plant cultivation and relates to a method for planting apocynum apocynum in a salinized desert in an arid area under the condition of drip irrigation. Background technique [0002] Saline-alkali land is widely distributed in Xinjiang. Affected by the arid climate and closed inland basins, the saline-alkali land in Xinjiang has the characteristics of large area, many types, heavy salt accumulation, and complex formation. The total area of ​​saline-alkali soil in Xinjiang is 8.476×10 6 hm 2 , 31.1% of the existing cultivated land is affected by salinity. Xinjiang is an important strategic reserve area of ​​reserve cultivated land resources in the country, and the main body of reserve cultivated land resources suitable for development is saline desert. Under the circumstances of increasing population and decreasing cultivated land area, the scientific and efficient development and utilization of saline-alkali land...
