Embodiment 1

[0020] Embodiment 1, the determination of the core component potassium acetate concentration in the drought-resistant agent and the preparation of the drought-resistant agent

[0021] (1) determine potassium acetate concentration

[0022] The inventor of the present application utilizes the potassium acetate treatment cotton of clear water, 5mM, 10mM, 15mM and 20mM respectively (each processing: every pot 5 strains, 9 repetitions, totally 45 strains of cotton seedlings), do not water after processing, carry out after processing 10 days Rehydration treatment, statistical determination of cotton survival rate and cotton dry matter weight. It was found that potassium acetate treatment can enhance the drought resistance of cotton and improve the survival rate of cotton, and the survival rate of cotton seedlings treated with 10mM, 15mM and 20mM potassium acetate was 2.46 times, 2.65 times and 2.84 times higher than that of the clean water control respectively ( figure 1 ); 10mM an...

Embodiment 2

[0025] Embodiment two, anti-drought agent preparation and application

[0026] Prepare phosphate buffer solution, the dissolution formula of phosphate buffer solution is: disodium hydrogen phosphate: 0.089g, sodium dihydrogen phosphate: 0.165g, add about 800mL of deionized water and stir to dissolve, then add concentrated hydrochloric acid to adjust the pH to 6.5, and finally Dilute to 1L; then weigh 1.47g of potassium acetate and dissolve it in phosphate buffer solution, which is the anti-drought agent (concentration of potassium acetate is 15mM).

[0027] For indoor cultured plants, before the arrival of drought stress, the drought-resistant agent can be directly irrigated to the root system, which can improve the drought resistance of the plant and the survival rate under drought stress.

Abstract

The invention provides a plant drought-resistant agent and an application thereof. The core component of the drought-resistant agent is potassium acetate. Potassium acetate is used as a core componentof the plant drought-resistant agent for the first time, and when potassium acetate is dissolved in a phosphoric acid buffer solution, alkalinity of potassium acetate can be neutralized, and harm ofa high pH value to plants is eliminated. Tests show that after the drought-resistant agent is applied, the expression of ABA and JA synthetic genes in plants is improved, and the drought resistance ofthe plants and the survival rate of the plants under drought stress are improved by improving the content of ABA and JA of the plants. Potassium acetate in the drought-resistant agent contains potassium ions, a phosphate buffer solution contains a phosphorus element, potassium and phosphorus are nutrient elements necessary for plants, and the dual purposes of fertilization and drought resistancecan be achieved. The drought-resistant agent can be applied together with other inorganic fertilizers, organic fertilizers or plant nutrient solutions and the like, is convenient to apply, and provides an effective way for improving drought resistance of crops.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology, and in particular relates to a drought-resistant agent for improving drought resistance of plants. The drought-resistant agent is mainly composed of potassium acetate, which can improve the drought-resistant ability of plants such as cotton. Background technique [0002] my country is a country with severe drought and water shortage. The total fresh water resources are 2.8 trillion cubic meters, and the per capita water resources are only 1 / 4 of the world's average level. It is one of the countries with the poorest per capita water resources in the world. Nearly half of my country's land is in arid and semi-arid regions. Drought stress seriously affects crop growth and yield. Under drought stress, on the one hand, plants promote root water uptake through strategies such as synthesizing and accumulating osmotic protection substances, and on the other hand, they reduce transpiration by re...
