The area of ​​vegetable land in the test area is 15hm2. 20 solar insecticidal lamps were installed through the underground cement blocks in the center and surrounding of the vegetable plots. They were arranged in a checkerboard pattern. The distance between the lamps and the lamps was 150-200 m. 1 lamp controls the vegetable field area from 1 to 1.33hm2. The insecticidal lamp of the solar insecticidal lamp is 1.3 to 1.5 m above the ground.

Reduce the use of pesticides, reduce farmland environmental pollution and pesticide residues in vegetable samples, and have little impact on natural enemies. Save work and save time, reduce labor workload, insecticidal lamps can improve product quality and safety and vegetable quality, solar insecticidal lamps can also improve the competitiveness and system of green food, maintain the sustainable development of the vegetable industry, economic benefits, Social and ecological benefits are significant.
