In 2009, the Yuexi County Forestry Bureau used solar radiation pest-killing lamps to prevent and control deep forest diseases and insect pests. The effect analysis is as follows, which provides a basis for the use of solar radiation pest killer lamps.
1, the trapping effect is significant
As the solar radiation insecticidal lamp mass trapped the female insects of the pine caterpillars, the second generation larvae of the caterpillars caterpillars in the area of ​​the lamps were compared with the unsuspended lamps. Diseases and insect pests decreased, and about 90% of second-generation larvae of the pine caterpillar were reduced. At the same time as trapping and killing of pine caterpillars, more than 200 species of other insect pests such as Lepidoptera and Coleoptera, Homoptera, and other forest pests were trapped and killed. Iv Reduced the breeding base of forest pests.
2, is conducive to the protection of human enemy insects
By comparing and analyzing the trapped insects, the proportion of beneficial insects and pests induced by solar radiation type insecticidal lamps is about 1:60, and the enemy insects have low lethality and effectively protect the forest human enemy insects. Achieving natural control has played an important role.
3, analysis of wood efficiency
Each 30W solar radiation type insecticidal lamp is about 50Cyuan, which can be used for at least 5 years. Its control area is about 5hm2. The number of lights is 150, including 8 lamps per person for the whole year. The total cost of lamps, equipment, electricity, and chemical treatments totals 70 yuan per hectare, which is about half that of chemical control.
The welding nozzle is the most important parts of the mig welding torches.Also we have different types suit for BZL Type Welding Torch, PANA Type Welding Torch, TW Type Welding Torch. And compatible American type welding torch BND welding torch,TRE welding torch, MIL welding torch,etc.
