Problems solved by technology

At present, leaf vegetable immune agents are also used in agriculture. The more common ones are compounded with various chemical components. The components are complex, the safety of crops needs to be discussed, and the application cost is high; some are compounded with plant growth regulators. However, the residue of growth hormone has led to new problems; at the same time, there is also an immune agent prepared by a special fermentation process from plant beneficial endosymbiotic bacillus, that is, plant biocontrol immune agent technology, but It takes a lot of work to screen strains, and large fermentation equipment requires a lot of investment

preparation example Construction

[0024] Further, the present invention also relates to a method for preparing a leaf vegetable immune agent, comprising the following steps:

[0025] (1) Weigh each component according to the proportion;

[0026] (2) Stir, dissolve, and mix well to obtain.

[0027] Furthermore, the present invention also relates to the application of the leafy vegetable immune agent in improving the immunity of leafy vegetable crops. The leafy vegetable crops are common leafy vegetable crops, such as celery, spinach, lettuce and the like.

[0028] Furthermore, if the concentration of the active ingredient in the leaf vegetable immunization agent is too low, its anti-drought effect cannot be exerted, and if the concentration is too high, it will have an impact on the crops. Therefore, when applying, it is preferable to dilute with water until the mass fraction of chitin and its derivatives is 0.00067%~ 0.008%, more preferably diluted to a mass fraction of chitin and its derivatives of 0.00213%...

Abstract

The invention relates to a leaf-vegetable immunizing agent and an application thereof, which belongs to the field of crop production. Aiming to solve the technical problems, the invention provides a leaf-vegetable immunizing agent and an application thereof. The leaf-vegetable immunizing agent provided by the invention comprises the following active components in parts by weight: 1-6.4 parts of chitosan and derivatives thereof, 0.4-4 parts of nitrogen, 0.3-1.0 part of phosphoric acid and 0.8-5.0 parts of potassium chloride, wherein the chitosan and the derivatives thereof are water-soluble chitosan and derivatives thereof; nitrogen is nitrogen elements and components which do not react with the water-soluble chitosan and the derivatives thereof for generation of a precipitate, and the mass of nitrogen is based on nitrogen elements. The invention also relates to an application of the leaf-vegetable immunizing agent. The components of the leaf-vegetable immunizing agent are harmless to human body and environments, and the leaf-vegetable immunizing agent does not cause hormone residues, is low in production cost, and meanwhile has the advantages of good effects on improvement of crop immunity and the like.

Description

technical field [0001] The invention relates to a leaf vegetable immune agent and its application, belonging to the field of crop production. Background technique [0002] With the continuous increase of my country's population, the rapid development of industry and the continuous acceleration of urbanization, and the reduction of cultivated land, how to improve crop immunity, reduce the possibility of disease occurrence, and increase crop yield is the key direction of agricultural research. [0003] Leaf vegetable immunizers can increase the resistance of crops to diseases, and can keep crops away from diseases to a certain extent. At present, leaf vegetable immune agents are also used in agriculture. The more common ones are compounded with various chemical components. The components are complex, the safety of crops needs to be discussed, and the application cost is high; some are compounded with plant growth regulators. However, the residue of growth hormone has led to n...
