preparation example Construction

[0076] Preparation of modified spirulina polysaccharide:

[0077] 1 # Modified spirulina polysaccharide sample

[0078] Spirulina polysaccharide and sulfuric acid (with H 2 SO 4 The mass meter) is mixed according to the mass ratio of 20:1 to obtain the mixed solution a, and then the solution is ultrasonicated at a frequency of 20KHZ for 1h under the condition of 55°C to obtain the modified spirulina polysaccharide, which is recorded as 1 # Modified spirulina polysaccharide samples.

[0079] 2 # Modified spirulina polysaccharide sample

[0080] with 1 # The difference between the modified spirulina polysaccharide samples is that the ultrasonic frequency is 30KHZ, the ultrasonic temperature is 50°C, and the ultrasonic time is 1.5h.

[0081] 3 # Modified spirulina polysaccharide sample

[0082] The difference from the 1# modified spirulina polysaccharide sample is that the ultrasonic frequency is 40KHZ, the ultrasonic temperature is 45°C, and the ultrasonic time is 0.5h....

Abstract

The application discloses an anti-plant virus disease composition and its preparation method and application. The anti-plant virus disease composition includes active components and inactive components, and the active components include active substance a and active substance b; the active substance a is a spirulina polysaccharide; the spirulina polysaccharide The substance includes spirulina polysaccharide or modified spirulina polysaccharide; the active substance b is selected from at least one of propyl dihydrojasmonate, seaweed extract, and brown algae polyphenol. The composition contains spirulina polysaccharides, and the spirulina polysaccharides are effective in preventing and treating plant virus diseases, especially tomato virus diseases, and the spirulina polysaccharides are derived from marine organisms, and have the characteristics of environmental friendliness, safety and environmental protection, and high activity. .

Description

technical field [0001] The present application relates to the technical field of compound medicines against plant virus diseases, in particular to an anti-plant virus disease composition and its preparation method and application. Background technique [0002] Plant virus diseases have become the main or primary diseases of tomatoes, sweet peppers, peppers, eggplants, watermelons, cabbage, radishes, grapes, peach trees and other fruits and vegetables in some areas of my country, resulting in reduced yields, fruit deformities, and quality declines, seriously threatening the capital’s agriculture. economic development. Plant virus diseases not only have a large number, wide range of hazards, large economic losses, but also are difficult to control. Therefore, plant virus diseases are called "plant cancers", which have attracted great attention from scientists from all over the world. Many studies have been done to prevent and control virus diseases. Some methods such as crop c...
