preparation example Construction

[0017] The invention provides a technical solution: a novel compound for improving plant resistance to soil aluminum toxicity and a preparation method thereof, a new substance for improving plant resistance to aluminum stress in products with melatonin and strigolactone as active ingredients .

[0018] The active ingredient of the complex is a mixed solution of melatonin and strigolactone.

[0019] The concentration of the compound mixed solution is: 10-100 μmol / L of melatonin and 0.1-1 μmol / L of strigolactone.

[0020] The concentration of the complex aqueous solution is 10 μmol / L of melatonin and 1 μmol / L of strigolactone.

[0021] The complex aqueous solution is prepared by diluting 10mmol / L melatonin ethanol solution and 1mmol / L strigolactone methanol solution.

[0022] The volume ratio of melatonin and strigolactone is 1-2:1.

[0023] The volume ratio of melatonin and strigolactone is 1:1.

Embodiment 1

[0025] A novel compound for improving plant resistance to soil aluminum toxicity and a preparation method thereof, comprising the following steps:

[0026] S1. First select 10 mmol / L melatonin ethanol solution and 1 mmol / L strigolactone methanol solution.

[0027] S2. Add the selected solution to the rooting medium at a ratio of 1:1, and then configure it as a medium containing a novel compound of 10 μmol / L melatonin and 1 μmol / L strigolactone.

[0028] S3. The plant selected is a monocotyledon or a dicotyledon, wherein the monocotyledon is wheat, corn, rice or leek, and the dicotyledon is acanthus, soybean, peanut or radish.

[0029] S4. Add the prepared culture medium of the novel compound into plants for use after suction filtration and sterilization.

Embodiment 2

[0031] A novel compound for improving plant resistance to soil aluminum toxicity and a preparation method thereof, comprising the following steps:

[0032] S1. Add the melatonin ethanol solution of 10mmol / L and the strigolactone methanol solution of 1mmol / L to the rooting medium in a ratio of 1:1, and be configured to contain 10 μmol / L of melatonin and 1 μmol / L of For the culture medium of the novel complex of strigolactone, select suitable monocotyledonous or dicotyledonous plants.

[0033] S2, make grouping control test, be divided into four groups altogether, wherein A group is the normal rooting medium, B group is to add compound in the normal rooting medium, and C group is to 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.

[0034] S3. The four groups of plants were subcultured for one month under the conditions of a culture room temperature of 25°C and a light intensity of ...

Abstract

The invention discloses a novel compound for improving soil aluminum toxicity resistance of plants and a preparation method thereof, relates to the technical field of plant planting, and provides a novel substance of a product taking melatonin and strigolactone as effective components in improvement of aluminum stress resistance of the plants. According to the novel compound for improving soil aluminum toxicity resistance of plants and the preparation method thereof, the activity of POD and CAT in the root system can be obviously improved through the proportioned compound, the SOD activity isreduced, the root system damage of the seedlings under the aluminum stress is further reduced; under normal growth and aluminum stress, the oxidative damage degree of the compound plant externally applied with melatonin and strigolactone is obviously lower than that of the root system of the compound plant which is not applied with melatonin and strigolactone; furthermore, the ROS caused by aluminum stress can be effectively removed by externally applying the melatonin and strigolactones compound so that the problems of plant dystrophy, poor growth and development and fruit yield and quality reduction caused by plant root poisoning due to the fact that aluminum ions are absorbed by plant roots are solved.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a novel compound for improving plant resistance to soil aluminum toxicity and a preparation method thereof. Background technique [0002] In recent years, due to unreasonable fertilization and management measures, soil acidification in apple production areas has become increasingly serious. In acidic soil, aluminum ions are absorbed by plant roots, causing plant root poisoning, causing plant nutritional disorders, poor growth and development, and fruit yield. Quality decline and other problems, quicklime is often used in daily life to alleviate soil acidification and aluminum toxicity effects, but long-term application will cause repeated soil acidification, therefore, while using traditional methods to alleviate soil acidity, find new ways to reduce aluminum toxicity. Plant damage is imminent, which is of great significance in agricultural production, and no one has studi...
