Recently, 50 solar insecticidal lamps were facilitated to Wulipai tobacco base of Suxian district, which were used to serve for the 2000mu high quality tobacco, rice, vegetable base. It was introduced that the lamp can convert solar power to electricity during the day time and trap insects at night. Assisted with this green and efficient way, no pesticide needs to be applied to the fields. The effective control areas of each lamp are 40-50mu. 200yuan chemical control cost can be saved for each mu. The agricultural products quality was upgraded greatly as well.
