Problems solved by technology

[0002] At present, the prevention and control of leek maggots is a difficult problem in the production of leeks. The chemical control methods of spraying or root irrigation with pesticides are mainly used. The disadvantage is that leeks absorb certain pesticides and remain in the body, which seriously endangers human health after eating. At the same time, due to In the process of leek disease prevention and control, we rely too much on chemical sterilization and insecticides, resulting in problems such as resistance of diseases and insect pests and chemical pesticide pollution. At present, there is no effective physical control method in the society.

Embodiment Construction

[0010] 1. Select a suitable ozone generator: According to the characteristics of leek maggots, it is required to select an ozone generator that produces more than 5 grams of ozone per hour.

[0011] 2. Preparation of ozone water: Connect the water inlet and outlet of the ozone generator to the water inlet and outlet pipes respectively, plug in the power supply, the ozone generator will start to work, and the generated ozone will automatically dissolve into the flowing water. The faster the speed is, the greater the amount of dissolved ozone will be, and the control effect will be more obvious;

[0012] 3. Watering: After thawing at the end of March every spring, pour ozone water on the leek field once. This time, the water should be thoroughly watered. After that, when the leek grows to about 15 cm, water it again. This time, just pour a small amount of water. Thereafter, 3 days after each crop of leeks was harvested, the ozonated water began to be poured when the leeks grew 5...

Abstract

The invention relates to a method for using ozone to prevent and control bradysia odoriphaga. The method is characterized by including selecting an ozone generator capable of generating more than 5g of ozone per hour; preparing ozone water; after thawing at the end of March in the spring each year, irrigating the ozone water in Chinese chive land for one time; when Chinese chive grows to be about 15 centimeters, irrigating the ozone water once again; three days after each crop of the Chinese chive is harvested, starting to irrigate the ozone water when the Chinese chive grows to be 5-8 centimeters, and irrigating the ozone water every other 7-10 days. The method can reach more than 90% in prevention and control rate of the Chinese chive maggots and is simple and convenient in operation, practical, safe, environment friendly, good in effect, free of resistance and suitable for Chinese chive planting.

Description

technical field [0001] The invention relates to the field of prevention and control of vegetable diseases and insect pests, in particular to a method for controlling chive maggots by using ozone. Background technique [0002] At present, the prevention and control of leek maggots is a difficult problem in the production of leeks. The chemical control methods of spraying or root irrigation with pesticides are mainly used. The disadvantage is that leeks absorb certain pesticides and remain in the body, which seriously endangers human health after eating. At the same time, due to In the process of leek disease prevention and control, we rely too much on chemical sterilization and insecticides, resulting in problems such as resistance of diseases and insect pests and chemical pesticide pollution. At present, there is no effective physical control method in the society. Contents of the invention [0003] The invention provides a method for preventing and treating leek maggots b...
