This invention relates to the field of contaminated soil remediation technology and discloses a method for phytoremediation of nonylphenol-contaminated soil enhanced with aminosalicylic acid, comprising the following steps: S1, contaminated soil pretreatment; S2, germination and seedling cultivation of *Astragalus membranaceus* seeds; S3, *Astragalus membranaceus* planting; S4, addition of aminosalicylic acid root exudates; S5, field management during the remediation period; and S6, remediation effect detection. By employing a synergistic remediation technology scheme using *Astragalus membranaceus* as the remediation plant and aminosalicylic acid as the core root exudate, the synergistic effect of these two substances recruits rhizosphere degrading microorganisms, enhancing the in-situ degradation process of nonylphenol, thus achieving efficient and in-situ remediation of nonylphenol-contaminated soil. Compared with existing technologies that rely solely on physical adsorption, chemical oxidation, or single phytoremediation, this method solves the problems of low remediation efficiency, easy secondary pollution, and limited applicability.

The application discloses a kind of saline-alkali soil eagle mouth Astragalus planting method and device, it is related to agricultural planting technical field, to the problem of line-shaped salt injury and seedling deficiency caused by membrane edge condensation back drop, the method is attached to the inside of membrane edge wet-sensitive developing tape positioning microclimate condensation back drop section;According to the interval of color change continuity, artificial pressure relief point is structured in membrane edge and is configured condensing wing piece, and continuous water vapor escape is converted into discrete fixed-point drop;Sacrificial salt interception zone is laid out in membrane outside alignment, and high-concentration condensed brine is instantaneously received and solidified to block its entry into soil;Risk avoidance lofting sowing is carried out in combination with safety bias distance, and after seedling is stable and becomes flat, salt interception zone loaded with salt is removed from farmland.The application realizes the precise positioning, discrete breaking and stripping of hidden salt damage, completely eliminates the pulse poison of edge salt line to seedling, and significantly improves the continuity and survival rate of saline-alkali soil vegetation construction.
