preparation example Construction

[0037] In the present invention, the plant preferably includes pakchoi; the application method preferably includes: applying a puerarin solution to the plant root system; the solvent of the puerarin solution preferably includes: a dimethyl sulfoxide solution and / or water , the concentration of the dimethyl sulfoxide solution is preferably 0.1 g / mL; when the solvent is water, the preparation method of the puerarin solution preferably includes: mixing water at 50° C. with puerarin to obtain the Puerarin solution. In the present invention, puerarin can be fully dissolved by mixing water at a suitable temperature with puerarin.

[0038] In the present invention, the alleviation of plant cadmium stress preferably includes: reducing cadmium absorption in plant roots under cadmium stress, reducing plant malondialdehyde content under cadmium stress, reducing plant hydrogen peroxide content under cadmium stress, and reducing plant cadmium stress under cadmium stress. amino acid conten...

Embodiment 1

[0042] The variety of pakchoi for test is "Danjiao Shanghai Qing", which is provided by Muyu Seedling Garden Co., Ltd. (see the product packaging picture). Figure 4 and Figure 5 ), the test puerarin was provided by Kuer Chemical Technology (Beijing) Co., Ltd.

[0043] Indoor hoagland nutrient solution was used for hydroponic cultivation, and pak choi seeds with similar size, complete shape, and similar growth degree were selected and sown in the soil. When the seedlings grow to two leaves and one heart, the seedlings with the same growth pattern are selected and transplanted into Hoagland nutrient solution (hoagland) to slow the seedlings for 7 days. After slowing the seedlings, the seedlings with the same growth pattern are selected to carry out 7 treatments respectively, wherein the puerarin mother liquor is: The puerarin solution was dissolved in 0.1 g / mL dimethyl sulfoxide solution to make the final concentration of puerarin at 100 mg / L:

Abstract

The invention relates to the technical field of crop planting, in particular to application of puerarin in relieving cadmium stress of plants and / or increasing the yield of the plants. By applying puerarin to plants, cadmium stress of the plants can be relieved, and particularly, cadmium absorption of plant roots under cadmium stress is reduced, the malondialdehyde content of the plants under cadmium stress is reduced, the hydrogen peroxide content of the plants under cadmium stress is reduced, the proline content of the plants under cadmium stress is reduced, and the root weight and fresh weight of the plants under cadmium stress are increased; the plant growth regulator can promote plant growth, improve the total chlorophyll content of plants under cadmium stress, improve the enzymatic activity of superoxide dismutase, ascorbate peroxidase, catalase and guaiacol peroxidase of the plants under cadmium stress, improve the soluble protein and VC content of the plants under cadmium stress, promote plant growth and improve the yield of the plants.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to the application of puerarin in relieving plant cadmium stress and / or improving plant yield. Background technique [0002] In recent years, with the continuous acceleration of urbanization and industrialization, soil heavy metal pollution has reached a serious level. Among the heavy metal soil pollution, cadmium (Cd) pollution is the most harmful. Cadmium is a heavy metal with strong biological toxicity and a non-essential element for plant growth and development. When cadmium in plants accumulates to a certain extent, the plants will show symptoms such as yellow leaves, shortened stems, reduced lateral roots, reduced chlorophyll content, reduced activity of antioxidant enzymes and cell damage, which have an inhibitory effect on plant growth. In addition to affecting the normal growth of plants, cadmium stress also affects the physiological activities of plants, such as ph...
