Methods of controlling leek maggots with high temperature mulching

Abstract

The invention discloses a method for mulching film at high temperature to control Chinese chive maggots. The method comprises the following steps that 1, from late spring and early summer to late summer and early autumn, a film mulching method is adopted for controlling the Chinese chive maggots; 2, a weather forecast is confirmed, a day with the atmospheric temperature exceeding 25 DEG C and strong sun rays is selected to carry out film mulching; 3, film mulching is conducted; 4, the film is removed. According to the method for mulching the film at high temperature to control the Chinese chive maggots, by means of the characteristics of having more root systems, being resistant to high temperature and the like of Chinese chive, the temperature of water vapor in soil is increased by means of the method that the sun rays irradiate the plastic film and are focused, and the Chinese chive maggots in the soil are killed; the method mainly emphasizes the high solar illuminance exists, the insect source base number of the Chinese chive maggots in Chinese chive fields is killed, a green production guarantee is provided for outdoor Chinese chive in spring, summer and autumn and Chinese chive in a greenhouse in winder. The method has the advantages of being easy to operate, rapid, efficient, low in control cost, capable of saving labor and time, green, environmentally friendly, good in Chinese chive maggot controlling effect, long in lasting period and the like.

Description

technical field [0001] The invention relates to a method for high-temperature film-coating, continuous and high-efficiency prevention and treatment of chive maggots, and belongs to the technical field of physical prevention and control of agricultural pests. Background technique [0002] Leek has good edible value and medicinal value. Leek is rich in nutrition. Every 500g of fresh leek contains 12g of protein, 2.5g of fat, 19g of sugar, 280mg of calcium, 225mg of phosphorus, 6.5mg of iron, 17.5mg of carotene and 95mg of vitamin C. Leek has the functions of lowering blood fat, treating cardiovascular and cerebrovascular diseases and high blood pressure. Traditional Chinese medicine believes that leek tastes sweet and warm, nourishes kidney and Yang, disperses blood and detoxifies, harmonizes viscera, warms stomach, increases appetite, removes dampness and regulates blood, etc. Li Shizhen praised leeks as "the most beneficial of all dishes." Leeks are mainly distributed in V...

Problems solved by technology

However, the blind application of chemical agents can easily cause the leek maggots to develop drug resistance, and the leeks carry pesticide residues, resulting in serious production and safety hazards

At the same time, the labor intensity of pesticide application is high, and the labor cost is high. It is difficult to get results on the same day, and it is even more difficult to avoid the survival of a small number of leek maggots due to uneven application of pesticides, providing a population base for a large number of leek maggots in the later period.
