Embodiment 1

[0023] Embodiment 1 wood vinegar is to the inhibitory effect of pathogenic bacteria and the influence of wheat germination

[0024] 1 Materials and methods

[0025] 1.1 Materials for testing: root rot pathogens, Fusarium graminearum and Bipolarissorokiniana are placed in PDA medium for subsequent use; the wheat variety for testing is Jimai 22; wood vinegar is the stock solution developed by the present invention.

[0026] 1.2 Test method:

[0027] 1.2.1 Inhibition of wood vinegar on mycelial growth of wheat root rot fungus

[0028] After the PDA medium is sterilized, mix with wood vinegar at 0.02%, 0.05%, 0.1%, 0.20%, 0.25%, 0.3%, 0.4%, 0.5%, 0.6%, 0.8%, 1.0%, 1.5% and 2.0% Prepared according to the ratio, pour it into a 9cm petri dish, pour 3 dishes for each concentration, and pour 20mL into each dish. After 2 kinds of wheat root rot pathogenic bacteria are placed in the PDA medium and cultivated for 10d, punch out 2 (diameter 5mm) bacterium cakes on the plate medium conta...

Embodiment 2

[0050] Embodiment 2 Preparation of a kind of anti-wheat root rot plant source disease-resistant growth-promoting agent and its application

[0051] 1. The raw material component weight part of a plant source disease-resistant growth-promoting agent of resistance to wheat root rot is as follows:

[0052] 55.5 parts of wood vinegar; 6.5 parts of potassium fulvic acid; 19 parts of urea; 19 parts of potassium nitrate.

[0053] Conforms to the standard of water-soluble fertilizer containing humic acid.

[0054] 2. The preparation main steps of a plant-derived disease-resistant growth-promoting agent of resistance to wheat root rot are as follows:

[0055] (1) Chelation reaction: Add various raw materials into the automatic feeding device, and add them to the reaction kettle in turn according to the characteristics of the raw materials, first add wood vinegar, then add potassium humate, stir and dissolve, finally add urea and potassium nitrate, heat to 70°C, adjust the pH value to...

Embodiment 3

[0062] Embodiment 3 Preparation of a kind of anti-wheat root rot plant source disease-resistant growth-promoting agent and its application

[0063] 1. The raw material component weight part of a plant source disease-resistant growth-promoting agent of resistance to wheat root rot is as follows:

[0064] 80 parts of wood vinegar; 9 parts of potassium fulvic acid; 8 parts of urea; 3 parts of potassium nitrate.

[0065] 2. A preparation step of a plant-derived disease-resistant growth-promoting agent resistant to wheat root rot:

[0066] (1) Chelation reaction: Add various raw materials into the automatic feeding device, and add them to the reaction kettle in turn according to the characteristics of the raw materials, first add wood vinegar, then add potassium humate, stir and dissolve, finally add urea and potassium nitrate, heat to 80°C, adjust the pH value to 5.5, and perform chelation reaction for 1 hour. After the chelation reaction is completed, cool to room temperature. ...

Abstract

The invention discloses a plant-derived disease-resistant growth promoter for resisting wheat root rot and application thereof. According to the invention, a product of plant pyrolysis and gasification, pyroligneous liquor, is used as a disease-resistant raw material; meanwhile, organic substance humic acid for promoting the growth of plant root systems is added; the invention develops a plant-derived disease-resistant growth promoter for resisting wheat root rot and an efficient application method thereof. According to the invention, the effect of preventing and treating root rot is achievedwhile the growth of wheat root systems is promoted, a corresponding application method is formulated, the efficient utilization of the growth promoter is achieved, a material guarantee is provided forfertilizer and pesticide application reduction and synergy and production of high-quality and high-efficiency agricultural products, and the efficient utilization of waste resources is achieved.

Description

technical field [0001] The invention relates to a plant-derived disease-resistant growth-promoting agent for resisting wheat root rot and an application thereof, belonging to the field of plant growth regulators. Background technique [0002] Wheat root rot is a soil-borne disease caused by a variety of pathogenic fungi, among which Fusarium and Helminthes are more common. These pathogenic bacteria can survive in the soil for a long time and can occur throughout the wheat growth period. Once the conditions are right, the disease is easy to expand and cause disasters. Generally, it can lead to a 20% to 30% reduction in wheat production, and in severe cases, it can reach more than 50%, seriously affecting wheat production. Wheat root rot is not easy to be found in the early stage of infection, and the best control period has been missed when obvious symptoms appear in the upper part of the ground. In agricultural production, the main method of preventing and controlling the ...
