Problems solved by technology

However, in the current ginger planting process, ginger blast is an important disease that hinders ginger planting and the sustainable development of the ginger industry. It is serious, easy to spread, and difficult to control. It has spread in various planting areas in my country. After research It was found that ginger blast is a disease that destroys bacteria and fungi caused by Pseudomonas solanacearum. The incidence rate in the field is generally 10-20%, and severe cases reach 30-40%.
At present, the measures to prevent and control ginger blast mainly include soil treatment, medicament soaking and root irrigation treatment. The effect of soil treatment is better, but many soil fungicides sold on the market are highly toxic and destructive to the soil after use. The dosage is large, the cost of input is high, the duration of disinfection of ginger species is short, and the effect of prevention is poor. In the later stage of chemical pesticide root irrigation treatment, the amount of medicament used is large, which has a huge impact on the environment and the safety of ginger. Frequent use Chemical pesticides will seriously affect the quality and quality of ginger, and there are drug residues, which seriously restrict the sustainable development of food safety

Embodiment 1

[0013] The concrete steps of this embodiment are as follows:

[0014] Seed selection: Select healthy plants with plump lumps, fresh meat, bright skin color, hard texture, and no obvious disease characteristics in the disease-free ginger field, and harvest and store them separately, and then select the yellow-white color before planting in the second year , smooth-skinned and disease-free hypertrophic ginger as ginger seeds;

[0015] Planting rotation: first select a plot that is dry, easy to irrigate, and has not been planted with ginger or solanaceous plants for more than three years, then sprinkle 20 quicklime per mu into the plot before plowing, and plow evenly Dry the soil for 15 days;

[0016] Seed soaking and disinfection: Soak the seeds with 0.2% lime water clarified solution for 8 hours before sowing, remove and dry, then wet the dry and pure plant ash with clean water and use it to mix ginger seeds. After the ginger seeds are covered with plant ash Immediately...

Embodiment 2

[0020] The concrete steps of this embodiment are as follows:

[0021] Seed selection: Select healthy plants with plump lumps, fresh meat, bright skin color, hard texture, and no obvious disease characteristics in the disease-free ginger field, and harvest and store them separately, and then select the yellow-white color before planting in the second year , smooth-skinned and disease-free hypertrophic ginger as ginger seeds;

[0022] Planting rotation: first select a plot that is dry, easy to irrigate, and has not been planted with ginger or solanaceous plants for more than three years, and then sprinkle 35kg of quicklime per mu into the plot before plowing, and plow evenly Dry the soil for 10 days;

[0023] Seed soaking and disinfection: soak the seeds with 0.3% lime water clarified solution for 7 hours before sowing, remove and dry, then moisten the dry and pure plant ash with clean water and use it to mix ginger seeds. After the ginger seeds are covered with plant ash...

Abstract

The invention discloses a ginger bacterial wilt prevention and control method which includes the steps of seed selection, crop rotation, seed soaking for sterilization, growth period management and the like. In the growth period management, a sodium hydroxide water solution with the concentration being 0.5%-2% is adopted for treating the pulled out ginger disease strains and disease nests, foliage spray and root irrigation can be further conducted, and pesticide effect detection steps are creatively introduced. Compared with a traditional prevention and control method, the cost of bactericide is low, materials are easy to obtain, preparation is easy, bactericide residues are avoided, the growth environment of fresh ginger is improved to the maximum degree, the yield of fresh ginger is greatly raised, the quality of fresh ginger is greatly improved, the prevention and control effect on the ginger bacterial wilt is remarkable and can reach over 80%, and the ginger bacterial wilt prevention and control method is an effective prevention and control measure and easy to use and popularize in a large area.

Description

technical field [0001] The invention belongs to the technical field of ginger planting, and in particular relates to a method for preventing and treating ginger blast. Background technique [0002] Ginger is one of the main fragrant and health-care vegetables widely used all over the world.
