The role of frequency-vibration insecticidal lamp in controlling tobacco pests
The influence of flue-cured tobacco on the planting process is very large, and its occurrence area is relatively large, and the degree of damage is also serious. The long-term use of chemical pesticides not only increases the production cost, but also leads to the increase of pesticide residues in tobacco leaves, and the quality is reduced. Moreover, polluting the environment and killing natural enemies at the same time destroys the balance of the ecosystem and is not conducive to the sustainable development of the tobacco industry. In order to find a high-efficiency, low-cost, low-residue tobacco pest control method, the use of frequency-vibration insecticidal lamps for tobacco pest control demonstration provides a strong basis for the promotion of this technology.
Most pests have a phototaxis, are sensitive to light, and like to be near lighted places at night. The frequency-vibration insecticidal lamp is designed according to the phototaxis of the adult insects. The main components are the frequency-vibrating lamp and the high-voltage power grid. The frequency-vibrating lamp can generate light waves of a specific frequency to attract the pests to close; the high-voltage power grid is wound around the lamp. The surrounding pests can be killed or stunned to achieve the purpose of controlling pests.
Field wiring: main line length 1500m, using 10mm2 aluminum wire; poles with 6m high cement pipe; branch line length of about 700m, a total of eight rows, using 2.5mm aluminum wire, 4m high gold plated pipe. Demonstration installation: The effective control area of ​​each frequency vibrating insecticidal lamp can reach 2~4hm2, and it can be installed every 90m. The density of insecticidal lamp can be increased according to the situation outside the tobacco field. The installation height is 1.5m from the ground, and it is fixed on the pole to prevent the wind from swinging or damaging the insecticidal lamp and affecting the trapping effect. The bottom is covered with the insect bag. The control area of ​​insecticidal lamps is large. At present, the area of ​​rural plots under the current system in China is small. Therefore, it is necessary to do a good job of coordinating the lights of all farmers. The traditional pesticide control is that after the tobacco farmers discover that the tobacco plants have insect pests, the targeted insecticides are used to kill the pests, which is passive control, and the control of the winged pests has little effect. The frequency-vibration insecticidal lamp specifically traps winged pests, and the killing rate of winged pests is over 98%, which is active prevention.
Biochemical products are a large number of products obtained by various biological reaction processes, including, or other processes. Their common feature is that the materials mainly derived from biological sources are used as raw materials, which are formed in the bioreactor through the action, and are extracted and purified by relevant means. Some of these products can also be produced by chemical synthesis, such as, etc. Whether to use chemical synthesis or biosynthesis should be determined from the comprehensive consideration of economic technology; some products can only be produced by biosynthesis or it is more economical and reasonable to use biosynthesis , such as, amylase, vitamin B, interferon and other substances with complex molecular structures; some products are produced by both chemical synthesis and biosynthesis, such as semi-synthetic penicillin, cortisone, vitamin C, etc.
Biochemical products can be divided into:
â‘ Bulk Chemical Products, such as ethanol, acetone, n-butanol, glycerol, citric acid, lactic acid, gluconic acid, etc.;
â‘¡Fine chemical products, such as various amino acids, enzyme preparations, nucleic acid products, etc.;
â‘¢Medical products, such as various, various steroids, conventional bacterin, vaccines, etc.;
â‘£Other products, such as biological pesticides, edible and medicinal yeast, feed protein (single-cell protein), biogas, etc.; Wait.
