Embodiment 1
[0040] Such as figure 1 Shown, a kind of Chinese chive leek maggot control method of the present embodiment may further comprise the steps:
[0041] Leeks are cut and dried;
[0042] Cover the soil with film to increase the temperature of the soil under the film;
[0043] Remove the soil and remove the film;
[0044] watering and fertilizing;
[0045] Wherein, the step covers the film and presses the soil and then airs in the sun, and the soil temperature under the film reaches more than 40 degrees Celsius and lasts for more than 4 hours to kill the leek maggots.
[0046] To prevent the harm of chive maggots to leeks, 3911 pesticides, namely phorate, are often used. 3911 pesticides kill leek maggots quickly and effectively. However, 3911 pesticides are highly toxic organic pesticides and are now banned. Other methods of preventing and treating chive maggots, such as variety improvement, cleaning up planting land, ozone disinfecting, placing color plates, etc., all have the...
Embodiment 2
[0084] On the basis of Example 1, the present embodiment describes the actual use of the leek maggot control method.
[0085] A piece of leek field, which has been planted for three years and has been harmed by leek maggots, is selected as the test field. After measurement, the test field is sandy loam soil with medium fertility, convenient drainage and irrigation, and the pH value of the soil is 6.0-6.8.
[0086] The test field is divided into four regions to carry out comparative experiments without repetition, among which three test fields are the test group that is tested according to the leek leek maggot control method, and the remaining one test field is the control group that does not mulch.
[0087] Among them, treatment 1: on August 14, the leeks were cut off at 8 o'clock in the morning and then dried for 24 hours, and the film was covered at 8 o'clock the next day, and the film was removed after 10 hours.
[0088] Treatment 2: On August 14, cut off the leeks at 7:00 ...

Abstract
The invention provides a Chinese chive maggot prevention and control method. The Chinese chive maggot prevention and control method comprises the following steps that Chinese chive is cut off, and airing is carried out; film covering and soil pressing are carried out so as to raise the temperature of soil under a film; soil removing and film uncovering are carried out; and watering and fertilizingare carried out. In the step of film covering and soil pressing, it is guaranteed that the temperature of the soil under the film reaches 40 DEG C or above and lasts for 4 hours or above, so that Chinese chive maggots are killed. The problems that an existing Chinese chive maggot prevention and control method is low in speed and takes effect late are solved. According to the Chinese chive maggotprevention and control method, the soil temperature is increased and the soil humidity is kept in a film covering manner, so that an environment unfavorable for growth and development of the Chinese chive maggots is created, the Chinese chive maggots are killed, meanwhile, the Chinese chive keeps activity, the environment is restored in time, and the survival rate of Chinese chive is guaranteed; The Chinese chive maggot prevention and control method also has the advantages of low operation cost, convenience in implementation and environmental friendliness.
