Comprehensive control techniques should be adopted to control crop diseases, insects, grasses and rodents. When using pesticides for prevention and control, the corresponding pesticides should be selected. In the appropriate application period, the correct application method should be adopted, and the economical and effective pesticide dosage should be applied. It is not possible to increase the dosage and change the application method.
The electrostatic spray is used to spray the droplets by the high-voltage electrostatic generating device, and the deposition amount of the medicine droplets on the surface of the blade is significantly increased, and the effective utilization rate of the pesticide can be increased to 80%. The shortcoming is that the penetration ability of the canopy of the charged mist droplet plant is weak.
The circulating spray is equipped with a drug recovery device on a conventional spray machine, and the liquid medicine that has not been deposited on the target plant is collected and then returned to the liquid tank for recycling, which can greatly improve the utilization rate of the pesticide.
Computer Control This technology is based on the modern electronic computer control technology. The photoelectric component is used as the sensor. When the target is “discovered†under the nozzle, the liquid is sprayed, otherwise the nozzle stops spraying. This technology greatly improves the effective utilization of pesticides.
Pellet-based administration of a highly water-soluble agent for use in paddy fields may be carried out by a pelletized application technique. Just sprinkle the pills evenly into the field. It not only improves work efficiency by a dozen times, but also does not drift pesticides and does not pollute neighboring crops.
The application of the drug roll is mainly used for the use of a systemic herbicide. The foaming material which can absorb the liquid medicine is used as a plastering roller, and the liquid medicine is oozing out through the surface of the drum, and it is only necessary to contact the blade of the upper part of the weed. This method can almost completely apply the agent to the target plant without causing the liquid to spill and drip.
Deep application of this medicine is mainly aimed at pests and soil-borne diseases that harm underground rhizomes, such as cockroaches, cockroaches, golden worms, root lice, and root rot. These pests and diseases, as well as attachments such as mulch and greenhouses, are not effective in spraying the crops on the stems and leaves of the crops. Only when the fertilizers are concealed and applied to certain strata and parts can the control effect be improved, the pollution reduced, and the key points hit. In order to be deeply applied to the ground, in the past, the drug was inserted into the roots and strata of the crop by hand. Not only the work efficiency is low, but also the direct contact with the pesticide by hand is not safe for people. Therefore, it is necessary to use a hand-held tool such as a fertilizer-applying gun. Safe and convenient.
