Embodiment 1

[0016] Embodiment 1 takes tomato planting in Shanghai as an example

[0017] The tomato seedlings were raised on March 20, 2012, with an area of ​​0.05 mu, and the planting time was May 7, with a planting area of ​​0.5 mu, which was planted in a greenhouse.

[0018] 1. Before the tomato seedlings were raised, on the evening of March 19, 2012, 5kg of ozone water with a concentration of 12ppm was sprayed on the plots to be raised, and then covered with a layer of plastic film to keep the soil in a closed environment as much as possible. , so that the insecticidal and bactericidal effects of ozone water can be maximized. Remove the plastic wrap an hour before planting.

[0019] 2. During the seedling raising period, because the temperature is low, basically no pests and diseases will occur. On April 15, 2012, 1.5kg of ozone water with a concentration of 6ppm was sprayed on the leaves to achieve the effect of prevention and control.

[0020] 3. Before tomato planting, spray 70kg...

Embodiment 2

[0023] Embodiment 2 Take the cabbage planting in Shanghai as an example

[0024] Choose the way of live broadcasting, the planting time is September 15, the planting plot area is 1 mu, and it is planted in a greenhouse.

[0025] 1. Before sowing, spray 150kg of ozone water with a concentration of 15ppm on the planting plot in the evening of September 14, 2012, seal the greenhouse, and open it again the next morning.

[0026] 2. One week after emergence, in the early morning of September 26, 2012, spray 30 kg of ozone water with a concentration of 6 ppm to the tomato seedling foliage.

[0027] 3. September to November 2012 is the high incidence period of cabbage diseases and insect pests. We choose to spray 60kg of ozone water with a concentration of 10ppm on the leaves of cabbage every 4 days from September 30 to October 30, 2012. Be that 160kg of ozone water of 14ppm carry out soil spraying to the cabbage planting plot every 15 days.

[0028] 4. After November 1, 2012, pest...

Embodiment 3

[0029] Example 3 Take the 3-year-old Guifei rose grape in Shanghai as an example

[0030] It is planted in the way of thermal insulation and rain-proof cultivation in greenhouses, and the planting area is 2 mu.

[0031] 1. During the grape pompom period, after spraying 100kg of ozone water with a concentration of 10ppm on the grape vines on the evening of March 1, 2012 and March 4, 2012, seal the greenhouse and keep the vines in a relatively airtight environment as much as possible. In the environment, let the insecticidal and bactericidal effects of ozone water be maximized, and then open the door the next morning.

[0032] 2. During the grape germination period, spray 60kg of ozone water with a concentration of 6ppm on the leaves every 7 days from March 12 to April 15, 2012.

[0033] 3. During the flowering period of the grapes, 80kg of ozone water with a concentration of 8ppm was sprayed on the leaves every three days from April 20th to May 1st, 2012.

[0034] 4. From May...

Abstract

The invention discloses a novel method for carrying out crop pest control and prevention by applying ozone water. The method comprises the following steps of: at the initial stage of crop diseases and pests, spraying the ozone water to crops, wherein the ozone water is used for ground pest control and prevention or is used for underground pest control and prevention. The method overcomes the defects of high cost, serious pollution and the like which are caused by the fact that conventionally, pesticides are applied to carry out pest control and prevention; and the method utilizes strong oxidizing property of the ozone water, can realize multiple purposes by applying the ozone water for once, is low in control and prevention cost, effectively saves manpower and material resources, is acted on the crops, has high utilization rate and high response speed, can kill various germs and viruses on fruit trees and vegetables and effectively solves the problems of pesticide residue and environment pollution which are caused by application of the pesticides.

Description

technical field [0001] The invention relates to a method for preventing and controlling crop diseases and insect pests, in particular to a method for using ozone water to prevent and control crop diseases and insect pests. Background technique [0002] The so-called "food is paramount to the people", people's various physiological activities are inseparable from the premise of food. At present, the phenomenon of "poisonous vegetables, poisonous rice, and poisonous fruits" has become more and more serious in various places, and the severity has been included in the motion of the Fifth Session of the National People's Congress. [0003] Pesticides have become a major factor that endangers health in food, but we also know that without pesticides, it becomes a headache to solve pests and diseases, and the occurrence of pests and diseases is often closely related to bacteria and viruses, so we launched Research on the use of ozone water to kill bacteria and viruses. [0004] Ex...
