Embodiment 1

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

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

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

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

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 polluted soil, and relates to a method for promoting the enrichment of cesium and / or strontium in sunflowers by using a plant growth regulator. It is suitable for remediation and treatment of cesium and / or strontium contaminated soil. Background technique [0002] The radionuclides released by nuclear tests or nuclear accidents have attracted widespread attention as the most important potential nuclear pollution of the environment. On the premise of cost-benefit optimization analysis, the bioremediation technology of radionuclide-contaminated soil has become a research hotspot in recent years. Existing studies have shown that the absorption of radionuclides by most plants is very low, so screening and planting plants with higher enrichment capacity for radionuclides to effectively remove radionuclides in the soil is a good way to prevent contaminated soils....
