Problems solved by technology

Plutella xylostella control methods At present, the most commonly used control methods are pesticide control. The pesticides used mainly include diflubenzuron 700 times solution, 25% Kuaishaling 2000 times solution, 24% Wanling 1000 times solution, etc. Pesticide control is effective It is fast, but it is easy to produce drug resistance when used frequently. It needs several kinds of chemicals to be used together, and there is a problem of pesticide residues. It not only pollutes the environment, but also cannot meet people's requirements for pollution-free food and green food.
IPM (Integrated Pest Management) technology is the main direction of Plutella xylostella control. Related technologies include: agricultural control, physical control, biological control, etc. However, in the practice of sustainable control of Plutella xylostella, the existing methods have no Control has certain limitations, we need to develop new control methods under the existing technical conditions and combine them in order to better control diamondback moth

Embodiment 1

[0017] Chinese cabbage, mixed with mustard greens

[0018] Choose an experimental field with a flat terrain, an area of ​​10 mu, a deep plow layer, and high soil fertility. The soil quality is loamy soil, and the pH of the soil is close to neutral. Sow in autumn and fertilize according to different growth stages. Single cropping: the distance between plants is 0.2 meters; mixed cropping: the distance between plants is 0.2 meters, and the distance between cabbage and mustard is 0.2 meters.

[0019] In 2010, 2011, and 2012, Chinese cabbage and mustard were planted alone, and the comparison results of insect populations in mixed cropping are shown in Table 1:

Embodiment 2

[0024] Chinese cabbage, cabbage mixed

[0025] Choose a piece of flat terrain with an area of ​​10 mu, deep plowed layer and high soil fertility. The soil quality is loamy soil, and the pH of the soil is close to neutral. In the high experimental field, the soil quality is loam, and the pH of the soil is close to neutral. Sow in spring, and fertilize according to different growth stages. Single cropping: the distance between plants is 0.2 meters, mixed cropping: the distance between plants is 0.2 meters, and the distance between Chinese cabbage and cabbage is 2.0 meters.

[0026] In 2012, Chinese cabbage and Chinese cabbage were planted alone, and the results of the comparison of the number of insects in mixed cropping are shown in Table 2:

Embodiment 3

[0031] Kale, mustard greens mix

[0032] Choose an experimental field with a flat terrain, an area of ​​10 mu, a deep plow layer, and high soil fertility. The soil quality is loamy, and the pH of the soil is close to neutral. Sow in autumn and fertilize according to different growth stages. Single cropping: the spacing between plants is 0.2 meters; mixed cropping: the spacing between plants is 0.2 meters, the spacing between cabbage and mustard is 1.0 meters, and cabbage is planted on the periphery of pakchoi and mustard.

[0033] In 2012, cabbage and mustard were planted alone and the results of the comparison of the number of insects in the mixed planting are shown in Table 3:

Abstract

The invention discloses a cultivation method for controlling quantity of diamondback moths by a mixed host vegetable cropping mode. Various host vegetables are cultivated to disturb choice behavior of the diamondback moths to the hosts so as to control population growth of the diamondback moths, and the vegetables can be harvested simultaneously by the mode. Effect is better if actual field production application is combined with other diamondback moth control measures (physical control, biological control and chemical control). By the cultivation method, consumption of chemical pesticide can be reduced, and the cultivation method is green, environmentally friendly and suitable for large-scale application.

Description

technical field [0001] The invention relates to a field cultivation method, in particular to a field cultivation method utilizing host interference to control diamondback moth. Background technique [0002] Plutella xylostella is a worldwide pest with strong reproduction and a wide range of damage. It mainly harms cruciferous plants such as cabbage, purple cabbage, broccoli, mustard greens, cauliflower, cabbage, rape, and radish. Plutella xylostella control methods At present, the most commonly used control methods are pesticide control. The pesticides used mainly include diflubenzuron 700 times solution, 25% Kuaishaling 2000 times solution, 24% Wanling 1000 times solution, etc. Pesticide control is effective It has the characteristics of quick and fast, but it is easy to produce drug resistance when it is used frequently. It needs several kinds of chemicals to be used together, and there is a problem of pesticide residues. It not only pollutes the environment, but also cann...
