Method for preventing and treating potato scab disease by adopting alkaline electrolyzed water

Abstract

The invention discloses a method for preventing and treating potato scab disease by adopting alkaline electrolyzed water, which comprises the following steps: step 1, diluting an alkaline electrolyzed water stock solution by 200 times to obtain a diluent for preventing and treating potato scab disease; the soil acidity and alkalinity of a potato tuber forming area are adjusted. According to the method for preventing and treating the potato scab disease by adopting the alkaline electrolyzed water, the alkaline electrolyzed water is diluted to serve as a scheme for preventing and treating the scab disease, so that the environment around potato tubers is not suitable for growth of the scab disease any more, the effect of preventing and treating the scab disease is achieved, residues and pollution are avoided in the whole process, soil cannot be damaged, and the method is suitable for large-scale popularization and application. The soil conditioning effect can also be achieved.

Description

technical field [0001] The invention relates to a method for preventing and treating potato powder scab by using alkaline electrolyzed water. Background technique [0002] As a common soil-borne disease of potatoes, powder scab has always been a difficult problem for potato growers, even worldwide. In recent years, it has shown a trend of large outbreaks, seriously affecting the yield and quality of potatoes, causing a large reduction in potato production and income, and even For the headache. The harmful symptoms of powder scab mainly damage the tubers and roots; on the tubers, brown dots first appear on the epidermis, with translucent halos on the periphery, and then the small spots gradually bulge into blisters of different sizes, and the surface ruptures. A large amount of dark brown powder was emitted. After the lesion breaks, the epidermis rolls back, the center of the lesion sinks, and there is often a corky ring around the periphery. For the root, the manifestation...

Problems solved by technology

Increase the base fertilizer or phosphorus and potassium fertilizer, apply more lime or plant ash, change the soil pH value, strengthen field management, promote high border cultivation, avoid flood irrigation, and prevent the spread of germs. Scab solution, although the soil is not suitable for the growth of potato powder scab, it will cause soil compaction and change soil activation properties

[0004] According to actual application needs, the existing prevention and control method is not only a large amount of work before breeding, but the root irrigation with fluazinam is used during the growth cycle of potatoes, but its effective control rate is below 30%. With the increase of drug resistance, the effectiveness of this method is also greatly reduced. At the same time, the existing chemical control methods also make the drug residues in potatoes exceed the standard, causing great damage to the soil. Transferred to other crops, contradicting the existing concept of planting green and organic agricultural products
