Embodiment 1

[0049] Under auxin treatment 133 Cs, 88 The effect of Sr on sunflower growth

[0050] This experiment was carried out in the laboratory building, East 6th Building, School of Life Science and Engineering, Southwest University of Science and Technology. The sunflower seeds to be tested were purchased from Taigu County Lvbao Seed Industry Co., Ltd., named Shanxi Huakui, an early-maturing drought-resistant variety, and simulated strontium and cesium pollution Soil, the pollution concentration is 20mg / kg (Strontium with Sr(NO 3 ) 2 As the source of strontium, cesium uses CsCl as the source of cesium), and the soil without strontium or cesium pollution is used as the control. Sunflower seedlings will start on March 19th. When the seedlings grow to one month, they will be planted in plastic pots (diameter 30cm, height 23cm) containing 6kg of strontium and cesium contaminated soil (see Table 1-1 for the physical and chemical properties of the soil) After 1 month, spray the auxin formula...

[0062] Gibberellin treatment 133 Cs, 88 The effect of Sr on sunflower growth

[0063] This experiment was carried out in the laboratory building, East 6th Building, School of Life Science and Engineering, Southwest University of Science and Technology. The sunflower seeds to be tested were purchased from Taigu County Lvbao Seed Industry Co., Ltd., named Shanxi Huakui, an early-maturing drought-resistant variety, and simulated strontium and cesium pollution Soil, the pollution concentration is 20mg / kg (Strontium with Sr(NO 3 ) 2 As the source of strontium, CsCl is used as the source of cesium), and the soil without strontium and cesium pollution is used as the control. Sunflower seedlings started on March 19, 2011. When the seedlings grow to 1 month, they will be planted in plastic pots (diameter 30cm, height 23cm) containing 6kg of strontium and cesium contaminated soil (see Table 1 for the physical and chemical properties) After 1 month, spray the gibberellin with soil formula (...

Abstract

The invention discloses a method for promoting sunflower cesium or / and strontium enrichment by use of a plant growth regulator. The method is characterized by comprising the following steps: planting sunflowers in soil containing pollutants-cesium and or / strontium, and spraying the plant growth regulator; when the plant-sunflowers grow to the maturation stage, removing the whole or overground parts of the plants-sunflowers from the polluted soil; furthermore, planting the next batch of sunflowers, and spraying the plant growth regulator; when the new planted plants-sunflowers grow to the maturation stage, removing the whole of the plants-sunflowers from the polluted soil; and repeating the process until the content / contents of the cesium and / or the strontium in the soil reaches the standard for environmental safety. In the method disclosed by the invention, the cesium / strontium absorption ability of the sunflowers is obviously enhanced under the effect of the plant growth regulator so as to permanently solve the problem of cesium / strontium pollution of the soil; the method has the characteristics of low treatment cost, no damage to environmental soil structure, no secondary pollution and the like, and brings good environmental benefits, social benefits and economic benefits.

Description

Technical field [0001] The invention belongs to the treatment of cesium and strontium pollution and the regeneration of contaminated soil, and relates to a method for using a plant growth regulator to promote the enrichment of cesium or / and strontium in sunflower. It is suitable for the remediation of soil contaminated by cesium and / or strontium. Background technique [0002] The radionuclides released by nuclear tests or nuclear accidents have received widespread attention as the most important potential nuclear pollution in the environment. Under the premise of optimization analysis of costs and benefits, the bioremediation of radionuclide contaminated soil has become a research hotspot in recent years. Studies have shown that most plants have very low absorption of radionuclides. Therefore, screening and planting plants with a high concentration of radionuclides to effectively remove the radionuclides from the soil is a contaminated One of the effective methods for soil biore...
