Abstract

The invention discloses a pest prevention device for agricultural planting. The device comprises a base, wherein the lower surface of the base is detachably connected with a steel needle, the side face of the steel needle is evenly provided with inclined barbs, the center of the upper surface of the base is provided with a hollow web member and a supporting rod telescopically cooperating with theweb member, the top of the supporting rod is provided with a yellow sticky board, the base is provided with an arc-shaped waste groove, the middle of the supporting rod is provided with a rotating rod, thee end, away from the supporting rod, of the rotating rod is provided with a pest repellent belt, and the middle of the rotating rod is provided with a sprinkler head. The pest prevention device for agricultural planting has the advantages that through the cooperation of the steel needle and the barbs with a mounting plate, the device can be conveniently fixed; the web member and the supporting rod cooperate with an upper connecting hole and a lower connecting hole, so that the height of the device can be conveniently adjusted; the yellow sticky board and a pest inducer cooperate with a lighting lamp and a power grid to effectively kill pests; a beneficial insect repellent board drives beneficial insects away from the device to prevent accidental killing of the beneficial insects.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a pest prevention device for agricultural planting. Background technique [0002] Yellow board insect trapping technology is a fast, simple, green and environmentally friendly efficient insecticidal technology for trapping and killing insects. Use the tendency of pests to colored light to lure pests to pounce on the color board with glue, and stick the pests to the yellow board to achieve the effect of pest control. However, when the yellow board is put into use, it is necessary to fix the yellow board in an appropriate position to catch insects. Because it is difficult to find a suitable hanging position in the farmland, it is troublesome to install on the one hand, and it will also affect the insect-catching effect on the other hand; It will continue to grow taller, and if the installation height of the yellow board cannot be adjusted, it will also affect the i...

Problems solved by technology

However, when the yellow board is put into use, it is necessary to fix the yellow board in an appropriate position to catch insects. Because it is difficult to find a suitable hanging position in the farmland, it is troublesome to install on the one hand, and it will also affect the insect-catching effect on the other hand; It will continue to grow taller, and if the installation height of the yellow board cannot be adjusted, it will also affect the insect-catching effect

In addition, the simple way of killing insects with yellow boards has gradually been unable to meet the needs of farmland sterilization. In order to achieve better insecticidal effects, it is necessary to combine a variety of insecticidal methods to complete effective insecticide.
