1. Significance of using frequency-vibrating solar insecticidal lamps for green vegetables production With the rapid growth of China's national economy, people's living standards have increased significantly and people have paid more and more attention to food hygiene and safety. Producing high-quality, non-leafed agricultural products is an important guarantee for food safety. In many technologies of agriculture, physics, and biological control of pests and diseases, the frequency-vibration insecticidal lamp utilizes the tendency of insects to light and waves to attract adult insects, and the lamp is externally matched with a frequency-vibration type high-voltage power grid to inject pests, which are green in production. One of the most direct and effective measures for agricultural products and environmental protection is economic, ecological and social benefits.
2. Application of frequency-vibration solar insecticidal lamps in pollution-free vegetable production bases In 2006, we installed 15 insecticidal lamps in a pollution-free vegetable production base in Xiaojing Town (Henan Province, Tangyin Jiaduoke Industry & Trade Co., Ltd. ) The radiation area is 1,000 mu. In 2007, it increased by 75 ç› and the area expanded to 6,000 mu. After two years of operation, it showed a huge insecticidal advantage of the insecticidal lamp.
3, insecticidal effect
3.1 Solar insecticidal lamp trapping species According to the results of daily observations from July 1st to July 30th, 2006, insecticide traps and insect pests involved 6 orders, 12 families and 44 species (as shown in the following table). The insecticidal spectrum was very wide.
3.2 Insect killing amount is large In August 1st to 30th, the average number of trapped insects was 7,654, and the average number of traps per day was 255.13. The main pests for culling and killing were: 2541 heads of beetles, 1072 heads of pea beetles, 408 heads of cotton bollworms, 198 heads of corn borers, and 178 heads of small earthworms.
3.3 Insect killing lamps have a small lethal effect on natural enemies. Because frequency-vibration insecticidal lamps use light sources and wavelengths that can avoid natural enemies, they have little lethality against natural enemies. Within 15 days of August 2-16, a total of 25 natural enemies were trapped in a single lamp and accounted for 0.64% of the total amount of trapped insects. 3,602 heads of trapped and killed insects accounted for 99.36% of the total amount of trapped insects, and the ratio of harm to injury was 1:154.48. .
4, economic benefits
4.1 Cost
4.1.1 Installation cost: The investment is 25 yuan per mu, and the service life is 5 years. The average annual expense is 5 yuan per mu.
4.1.2 Electricity fee: 30W per lamp, 12 hours per day, 150 days per year, 0.56 yuan per kilowatt hour, 30 yuan per year for a single lamp, 53 yuan per lamp, and 1.25 yuan per mu for the two items .
4.1.3 Routine Maintenance: The daily maintenance cost for a single lamp is 150 yuan per year, equivalent to 2.2 yuan per mu. The above three items total: 8.45 yuan/year.
4.2 The non-light area is used for 20-25 times per year, each dose is RMB 6.00 yuan per mu, and the annual cost is 120-150 yuan; the lamp area is used 10 times per year, and the cost per year is 60-90 yuan per mu, which saves labor. 5-7.5, equivalent to 150-210 yuan, saving labor costs for pesticides 210-300 yuan per mu per year. After deducting the cost, it will increase 200-300 yuan per mu.
5. Social and ecological benefits Solar insecticidal lamps can well protect natural enemies and maintain ecological balance. They can significantly reduce the use of chemical pesticides, reduce pesticide residues, reduce environmental pollution, and protect the ecological environment. It can improve the quality and market competitiveness of vegetables, and ensure the health of people and livestock. It is an ideal tool for the production of green vegetables, and its social benefits are very significant.
