Problems solved by technology

The invention uses the food chain principle in the ecosystem to prevent and control corn borer, which is simple to operate, safe and environmentally friendly, but at the same time, the control effect of the invention is limited, and there are restrictions on seasons and regions, so it is not suitable for large-scale application. At the same time, in a certain area, short When a large number of natural enemies are released, it will also affect the balance of biological populations in the area, which may cause biological hazards

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 1~5 Shown is the device for multiplying and sheltering natural enemies of field pests in the embodiment, including a greenhouse framework 1 and a film 2 laid on the greenhouse framework 1. The greenhouse is 8 meters wide, 8 meters long, 1.8 meters high at the shoulder, and 3 meters high at the top , including 17 bow rods 11 inserted into the soil and arranged in parallel (the distance between the bow rods is 0.7-1.0), 3 tie rods 12 vertically arranged on the top of the bow rods 11 at a certain interval, and the first vertically arranged on the outer periphery of the greenhouse respectively. , the second and the third lamination groove 41,42,43, wherein the first lamination groove 41 is arranged at 40cm from the ground, the second lamination groove 42 is arranged at 50cm from the roof center, and the third lamination groo...

Abstract

The invention relates to a device for propagating and shielding natural enemies of pests in the field, comprising a greenhouse framework and a thin film covering the greenhouse framework. The pest-preventing gauze, the skirt-edge film, the rolling film and the sun-shading net are used to simulate the shielding environment suitable for the natural enemies of pests to survive and propagate. The invention also relates to a method for preventing and treating pests by adopting the device. According to the method, the conventional method for killing by spraying pesticide is used first, and then the natural enemies of pests, which are propagated in the device, are used to kill the pests having strong pesticide resistance after being killed by adopting the conventional method for killing. The method combines the chemical prevention and treatment means with the biological prevention and treatment means. Compared with the prior art, the method has the advantages of improving the pest killing rate, prolonging the pest killing period and reducing the pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of agricultural pest control, in particular to a field pest natural enemy propagation and protection device and a method of use thereof. Background technique [0002] In the process of crop production, pest control is an important task, and it is also a key link in the realization of pollution-free production of agricultural products. In pollution-free cultivation, the principle of pest control is: prevention first, comprehensive control, to achieve safety, effectiveness, economy and convenience. Pest control techniques can be divided into chemical control using chemical substances such as fungicides or insecticides; physical control using physical energy such as light or rays, or building barriers; farming control that changes crop varieties, cultivation time or environment to reduce damage ; Biological control based on the use of natural enemies. Among them, chemical control is a commonly used pest contr...
