preparation example Construction

[0034] The embodiment of the present invention also provides a preparation method of the above-mentioned alkali stress treatment agent, the preparation method of the alkali stress treatment agent comprises the following steps:

[0035] 1) Add water to brassinolide in proportion to form an aqueous solution to obtain the first solution; add melatonin to water in proportion to form an aqueous solution to obtain the second solution; add water to strigolactone in proportion to form an aqueous solution to obtain the second solution Three solutions; standby;

[0036] 2) Mix the first solution, the second solution and the third solution uniformly according to the mass ratio of 0.5-1.5:0.5-1.5:0.5-1.5 to obtain the alkali stress treatment agent.

[0037] As another preferred embodiment of the present invention, the preparation method of the alkali stress treatment agent comprises the following steps:

[0038] 1) Add water to brassinosteroid to form an aqueous solution with a concentra...

Embodiment 1

[0054] A preparation method of an alkali stress treatment agent, comprising the following steps:

[0055] 1) Prepare the brassinosteroid with water to form an aqueous solution with a concentration of 0.2 mg / L to obtain the first solution and set aside;

[0056] 2) Mix melatonin with water to form an aqueous solution with a concentration of 0.1mmol / L to obtain the second solution for later use;

[0057] 3) Add water to the strigolactone to form an aqueous solution with a concentration of 0.1mmol / L to obtain the third solution for later use;

[0058] 4) Mix the first solution, the second solution, and the third solution uniformly according to a mass ratio of 1:1:1 to obtain the alkali stress treatment agent.

Embodiment 2

[0060] A method for improving the ability of plants to resist alkali stress, specifically using the alkali stress treatment agent prepared in Example 1, comprising the following steps: using the apple rootstock Pingyi sweet tea plant test plant, the alkali stress treatment agent prepared in Example 1 Spray once a day on the foliage of the plants (apple rootstock Pingyi sweet tea) subjected to alkali stress, and spray 20 times in total. Make sure that the amount of spraying is consistent every day. When spraying, pay attention to the uniformity of the alkali stress treatment agent. Spray on the surface of the leaves, while ensuring the right amount of tap water irrigation. The plant changes before and after the alkali stress treatment were detected respectively. This test group was recorded as the alkali stress group before the alkali stress treatment, and was recorded as the Example 1 group after the alkali stress treatment.

[0061] Among them, the alkali stress environment s...

Abstract

The invention relates to the technical field of planting, and particularly discloses an alkali stress treatment agent and a preparation method and application thereof. The alkali stress treatment agent is prepared from brassinolide, melatonin and strigolactones, damage of alkali stress to plants can be effectively relieved through cooperative use of the brassinolide, melatonin and strigolactones, the problems that most of existing methods for relieving damage of alkali stress to plants are achieved by improving soil, the environment is easily polluted, and soil hardening is caused are solved. The provided preparation method is simple, the prepared alkali stress treatment agent can adapt to local conditions and efficiently solve the influence of soil alkalization on plant growth, the alkali stress resistance of plants can be improved when the alkali stress treatment agent is applied to leaf surfaces and/or roots of the plants, and the alkali stress treatment agent has wide market prospects.

Description

technical field [0001] The invention relates to the field of planting technology, in particular to an alkali stress treatment agent and its preparation method and application. Background technique [0002] In the field of planting technology, environmental factors that are not conducive to plant metabolism and growth and development are collectively referred to as environmental stress, including soil alkalization, drought and temperature. According to the nature of the salt in the soil, the saline-alkali stress in plants can be divided into two types: salt stress and alkali stress. Alkali stress causes more damage to plants than salt stress. "Alkali stress" is one of the abiotic stresses, which is very harmful to agricultural production. It is the main stress that affects plant growth and development and leads to crop yield reduction, and it shows a continuous growth trend. At present, soil alkalization has become an important factor affecting agricultural production. [0...
