Embodiment

[0026] (1) Utilize phytohormone 2,4-EBL to strengthen the method for repairing copper-polluted water body of pothos, the method is as follows:

[0027] 1) Take the potted pothos out of the soil culture, rinse the roots with deionized water for more than 3 times, put them in water and cultivate them for 7 days, take the fresh weight of pothos 12g / plant as the screening condition, and select 5 plants of pothos with the same growth As a group, they were cultured in glass pots filled with 500mL 1 / 500 modified Hoagland nutrient solution, and the pots were placed randomly. Place them to avoid errors caused by environmental differences. After continuing to cultivate for 14 days, the roots are used for stress experiments after being domesticated by hydroponics;

[0028] 2) Copper stress is based on CuSO 4 ·5H 2 O (analytical pure) aqueous solution is added, the copper concentration is set to 300-500mg / L, and the plant hormone 2,4-EBL is added in the form of plant hormone ethanol aq...

Abstract

The invention discloses a method for enhancing scindapsus aureus by using plant hormone 2, 4-EBL so as to repair a copper-polluted water body. The method comprises the following operation steps: 1) planting scindapsus aureus in the copper-polluted water body, applying 0.01-10 [mu]M of plant hormone 2, 4-EBL, and growing and culturing; and 2) removing the grown and cultured scindapsus aureus from the polluted water body, and by means of repeated planting and repeated operation, achieving the purpose of accumulating excessive copper in the water body into the scindapsus aureus, and finally enabling the copper content in the polluted water body to meet the national water quality standard requirement. The plant hormone 2, 4-EBL is applied to enhance the scindapsus aureus to repair the copper pollution, so that the growth of the scindapsus aureus can be promoted, the heavy metal copper accumulation capability of the scindapsus aureus is improved, the water quality is improved, and the problems of low absorption rate of plants to heavy metals and slight water quality purification effect in the conventional phytoremediation are effectively solved.

Description

technical field [0001] The invention relates to the technology of strengthening plant repair by using exogenous plant hormones, in particular to a method for using plant hormone 2,4-EBL to strengthen pothos to restore copper-polluted water bodies. Background technique [0002] With the rapid development of modern industry, the total discharge of industrial wastewater is increasing, resulting in the discharge of many pollutants into the water, especially heavy metal pollution in water. Heavy metals are typical accumulative pollutants in the environment and are difficult to degrade. Once heavy metals enter the water body, it is difficult to restore the water body to its original state only by the self-purification ability of the water body. In addition, heavy metals in the aquatic environment are easy to migrate, so they can easily affect human health directly or indirectly through aquatic animals. In recent years, the content of heavy metals in seawater samples in my country...
