Embodiment Construction

[0023] In order to make the objectives, technical solutions and beneficial effects of the present invention clearer, the technical solutions in the present invention will be further described below in conjunction with examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The invention provides a method for the onset of corn plant sheath blight, comprising:

[0025] S1. Acquisition of sheath blight bacteria: take the tissue with diseased spots at the intersection of diseased and healthy parts of the stem and leaf of the corn sheath blight diseased plant, sterilize and remove miscellaneous bacteria, wash with water, dry the water, and cultivate in the first medium until the tissue grows. Go out mycelia; pick the top of the mycelium that grows from the edge of the tissue, cultivate it on the PDA slant medium, and set it aside;

[0026] S2. Purification of sheath ...

Abstract

The invention provides a method for the onset of sheath blight on corn plants, comprising: S1, acquisition of sheath blight bacteria; S2, purification of sheath blight bacteria; S3, expanded culture of sheath blight bacteria; S4, sheath blight bacteria Plant inoculation of pathogens. The invention improves the success rate and reliability of corn plant sheath blight disease by directly inoculating the plants with sheath blight bacteria.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for the onset of corn plant sheath blight. Background technique [0002] Corn is an important food crop and feed crop, and it is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn is rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing foods with high nutrition and high biological functions. [0003] Maize sheath blight is one of the main fungal diseases in the main maize producing areas in my country, and it shows a trend of aggravation and accelerated spread year by year, seriously restricting the yield and quality of maize. [0004] Maize sheath blight mainly damages leaf sheaths, leaves and ears, and also damages stems. Initially, the disease usually occurs from the leaf sheath near the ground, and gradually develops f...
