Embodiment 1

[0027] A method for applying a novel compound in improving plant resistance to soil aluminum toxicity, comprising the following steps:

[0028] S1. Selecting a mixed solution in which the compound is a mixed solution of melatonin and strigolactone in an appropriate proportion and concentration ratio, and performing filter sterilization.

[0029] S2, do grouping control test, be divided into four groups altogether, wherein A group is the normal rooting medium, B group is that compound is added in the normal rooting medium, and C group is that in the medium, add 100 μ mol / L aluminum chloride (PH= 4.5), in group D, 100 μmol / L aluminum chloride (PH=4.5) and the compound were added to the culture medium.

[0030] S3. Plants subcultured for one month under the conditions of a culture room temperature of 25° C. and a light intensity of 3000 lux were selected, and 48 plant seedlings with the same growth were selected and transplanted into a rooting medium for a total treatment period ...

Abstract

The invention discloses an application method of a novel compound in improving plant resistance to soil aluminum toxicity, and relates to the technical field of plant planting. By adding the compoundto a petri dish for plant culture, the application method can significantly enhance activities of SOD, POD, and CAT of plants that are oppressed by aluminum toxicity, that is, under normal growth andaluminum stress, the compound can significantly reduce the degree of plant oxidative damage, thereby effectively removing ROS caused by aluminum stress, reducing root damage, reducing possibility of plant death due to aluminum toxicity, thereby solving a problem that current compound application methods for treating and preventing plant aluminum poisoning have certain deficiencies and seriously affect plant growth and development.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to an application method of a novel compound in improving plant resistance to soil aluminum toxicity. Background technique [0002] Aluminum is the most abundant metal element in the earth's crust and is ubiquitous in soil. According to reports, 30% of the world's arable land and 50% of the potential arable land are acidic soils. Therefore, aluminum toxicity caused by soil acidification is currently a hot issue of global concern. In neutral or alkaline soils, aluminum mainly exists in insoluble forms such as alumina and aluminum silicate, which do not cause toxicity to plants; while in acidic soils, aluminum exists in the form of trivalent aluminum ions (Al 3+ ) form into the soil solution, combine with the plant root cell wall, and enter the cell symplast, inhibit mitosis and DNA synthesis, hinder the absorption of water and nutrients, and then inhibit the growth and functio...
