Embodiment 1

[0041] A kind of anti-salt stress agent that is used for wheat crops that the preferred embodiment of the present invention provides, because calcium humate is weak acid strong alkali salt, hydrolyzes into alkaline, can be directly dissolved in water, and sodium selenate is easily soluble in water. Add 1.89g of sodium selenate and 4.04g of calcium humate into 1L of water and dissolve completely to obtain a solution containing 4mmol / L sodium selenate and 10mmol / L calcium humate.

Embodiment 2

[0043] A salt stress resistance agent for wheat crops provided by a preferred embodiment of the present invention, since calcium humate is a weak acid and strong alkali salt, it is hydrolyzed into alkaline, the culture solution is acidic and can be directly dissolved in the nutrient solution, and Sodium selenate is soluble in water and also soluble in culture medium. Add 1.89g of sodium selenate and 4.04g of calcium humate into 1L of culture solution, dissolve completely to obtain a nutrient solution containing 4mmol / L sodium selenate and 10mmol / L calcium humate.

[0044] Among them, the culture solution is Hoagland's nutrient solution or Morad nutrient solution or horticultural balanced nutrient solution, with a pH of 6. The specific ingredients and ingredients are as follows:

Embodiment 3

[0052] A method for soaking seeds using a salt stress-resistant agent for wheat crops provided by a preferred embodiment of the present invention comprises the following steps:

[0053] S1. Soak the seeds of wheat crops in 10% sodium hypochlorite solution for surface disinfection for 10 minutes, and rinse the sodium hypochlorite with deionized water;

[0054] S2. The seeds treated in step S1 are placed in a petri dish covered with 3 layers of filter paper;

[0055] S3. Add the anti-salt stress agent solution prepared in Example 1 into the petri dish;

[0056] S4. Place the culture dish in a constant temperature light incubator with a temperature of (25±1)°C, 12h light / 12h darkness, and a humidity of 80%, and add distilled water in an appropriate amount to keep the filter paper moist, and co-culture for 7 days.

Abstract

The invention discloses an anti-salt stress agent for triticeae crops, and relates to the technical field of triticeae crop cultivation for triticeae crops. According to the application modes, the twomodes of soaking triticeae crop seeds and performing foliage spraying on seedlings are adopted. The reagent is composed of calcium humate and sodium selenate. The specific preparation method comprises the steps that calcium humate is treated to be added into a culture medium in the mode of 10 mmol / L Ca+, Na2SeO4 is treated to be added into the culture medium in the mode of 4 mmol / L SeO4<2->, andsufficient stirring is performed to be uniform to obtain the crops. The anti-salt stress agent can promote triticeae crop growth, it is ensured that triticeae crops can normally and healthy grow underthe salt and alkali stress, the triticeae crop yield and quality are effectively improved, the adopted ingredients are simple, the ratio is clear, the agent is environmentally friendly, the cost is low, the efficiency is high, industrial production is facilitated, and the good economic benefits and the social value are achieved.

Description

technical field [0001] The invention belongs to the technical field of wheat crop cultivation, and in particular relates to a salt stress resistance agent for wheat crops and a preparation method thereof. Background technique [0002] my country's salinized land accounts for about 10% of the country's land area, and with global warming, shortage of fresh water resources and continuous increase in population, this phenomenon is still intensifying. The vast area of ​​saline-alkali soil has become an important factor leading to the reduction of per capita arable land, the decline of arable land quality, and the deterioration of the ecological environment in my country, which has seriously affected the ecological balance and the sound development of agriculture and animal husbandry in our country. [0003] If the water-soluble salts in the soil surface or sub-surface layer (thickness is generally about 20-30cm) exceed 0.1% (or exceed 0.2% in the case of rich gypsum), or the alka...
