Wheat seed soaking agent as well as preparation method and application thereof

Abstract

The invention provides a wheat seed soaking agent, and belongs to the technical field of agriculture. The wheat seed soaking agent provided by the invention comprises the following raw materials in parts by weight: 1-5 parts of vitamin C, 1-5 parts of chitosan oligosaccharide, 1-5 parts of gibberellin, 6-10 parts of potassium fulvate, 35-60 parts of a chrysanthemum extract liquid and 35-60 parts of a moss extract liquid. The preparation method comprises the following steps: mixing the chrysanthemum extract liquid with the moss extract liquid, then adding the vitamin C, the chitosan oligosaccharide and the potassium fulvate into the mixed solution, stirring and dissolving, and then uniformly mixing with a gibberellin aqueous solution to obtain the wheat seed soaking agent. The components of the wheat seed soaking agent provided by the invention are compatible with one another, so that a natural bioactive protective film can be formed on the surface layer of wheat seeds, the activity of various enzymes of the wheat seeds is increased, the ability of crops to resist high temperature, freezing injury, salt and alkali, drought, diseases and the like is improved, and the yield and quality of the crops are improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a wheat seed soaking agent and its preparation method and application. Background technique [0002] Wheat is the staple food of the people in northern China, and it has been an important food for nourishing the human body since ancient times. Wheat, as the second largest food crop in my country, plays an important role in ensuring national food security. It is necessary to rely on science and technology to greatly increase the yield of wheat per unit area in order to meet the needs of population growth and social development. Therefore, research on high-yield wheat is an eternal research topic . [0003] my country's traditional wheat sowing mode has high investment, high cost, high consumption, low yield, excessive use of chemical fertilizers, resource problems are becoming more and more serious, and environmental pollution is very serious; moreover, most of my ...

Problems solved by technology

[0003] my country's traditional wheat sowing mode has high investment, high cost, high consumption, low yield, excessive use of chemical fertilizers, resource problems are becoming more and more serious, and environmental pollution is very serious; moreover, most of my country's wheat planting areas are located in the northern arid areas. After October, the rainfall is scarce, the water evaporation is large, and the soil drought is more common, which will easily lead to the influence of water absorption and expansion during the imbibition stage of wheat seeds, weaken the metabolic ability of seed embryos, and slow and irregular emergence of seedlings, which seriously affect the growth of wheat Post production and quality

Therefore, wheat seed dressings are more and more paid attention to by farmers. At present, there are many varieties of wheat seed dressings on the market, but usually adopt technical means such as breeding drought-resistant germplasm resources or adopting exogenous plant growth regulators to process. However, , the breeding of drought-resistant germplasm resources of wheat takes a long period, consumes a lot of manpower and material resources, and is prone to unfavorable factors such as mutations in traits, while exogenous plant growth regulators mainly include abscisic acid, brassinosteroids, and cytokinins. High cost, complex operation, unstable effect, etc.
