Embodiment Construction

[0012] 1. Strengthen inspection to prevent long-distance transmission of gall seeds. Set up disease-free seed fields and plant disease-free seeds.

[0013] 2. Remove galls from wheat seeds. Clean water selection, wheat seeds are poured into clean water and stirred quickly, the galls float up but are removed, and 95% of the galls can be eliminated. The whole operation should be completed within 10 minutes to prevent the galls from absorbing water and sinking. Use 20% salt water to eliminate galls more thoroughly than clean water, but wash the seeds with clean water afterwards. The ammonium sulfate liquid selection method can be washed with 26% ammonium sulfate liquid.

[0014] 3. Implement crop rotation for more than 3 years to prevent galls from being mixed into manure, and apply fully decomposed organic fertilizer.

[0015] 4. Chemical treatment of seeds. Mix the seeds with 50% methyl parathion or methyl isofenphos according to 0.2% of the seed amount. For every 100kg o...

Abstract

A novel method for preventing and controlling wheat seed gall nematodes is provided. The method is characterized in that the method includes enhancing examination, preventing distanced propagation ofseeds with insect galls, removing insect galls in wheat seeds, performing over-three-year rotation, preventing insect galls from being mixed into manure, applying fully decomposed organic fertilizers,treating the seeds with agents, controlling with agents, and the like; and the method overcomes yield decrease per mu and other problems caused by wheat seed gall nematodes. The method is particularly suitable for increasing the yield per unit area for farmers planting large-scale wheat.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a new method for preventing and treating wheat grain nematode disease. Background technique [0002] The leaves of the injured wheat seedlings are short and broad, wrinkled, yellowish, erect, and the severe ones shrivel and die. Before the heading of the diseased plants that can grow, the leaves are shrunken, the leaf sheaths are loose, the stems are twisted, and the flag leaves are deformed. After the booting stage, the diseased plants are short, the stalks are hypertrophic, and the internodes are shortened. The severely damaged ones cannot head, some can head, the glumes open, are not fruitful, and the grains become galls. Seriously affect the yield of wheat per mu. Contents of the invention [0003] The invention introduces a new technology of wheat disease prevention, and invents a new method of preventing and treating wheat grain nematode disease. [0004] The present inven...
