1. Low volume spray. This technology is the unit area in the case where the same application rate, the liquid pesticide relatively little water using conventional spraying techniques diluting with water 1/5 ~ 1/10. The specific method is to replace the large-aperture spray of the conventional spray machine with a small-aperture spray with a diameter of 0.3 mm. This can reduce the loss of pesticides and save a lot of water, significantly improve the control effect, and effectively overcome the wet damage caused by conventional spray to the greenhouse. This technology is particularly suitable for use in greenhouses and mountain areas where water is scarce.
2. Electrostatic spray. The technology is to install a high-voltage static electricity generating device on the spraying machine, and the high-pressure static electricity generating device is used to increase the deposition amount of the sprayed liquid droplet on the surface of the crop blade, and the effective utilization rate of the pesticide can reach 90%. Thereby avoiding a large number of pesticides entering the farmland soil and the atmospheric environment ineffectively.
3, "Pelletized" application. This technique is suitable for paddy fields. This method works well for water-soluble pesticides used in paddy fields. Simply apply the processed pills evenly to the farmland, which can increase the work efficiency by more than ten times than the conventional application method, and there is no pesticide drift phenomenon, which effectively prevents the crop stems and leaves from being damaged, and does not pollute the adjacent ones. crop.
4. Circulating spray. This technology is designed to retrofit a conventional sprayer with a drug return device on the opposite side of the spray component. Collecting the liquid that has not deposited on the target plant and pumping it back into the medicine box can recycle the pesticide, which can greatly improve the effective utilization rate of the pesticide and avoid the inefficient loss of the pesticide.
5. Apply the medicine roller. This technology is mainly suitable for the prevention and control of systemic herbicides. The liquid medicine is oozing out from the surface of the medicine roll by a medicine roller (a type of medicine overflowing made of a foam material capable of absorbing the liquid medicine), and the medicine roller only needs to contact the blade of the upper part of the weed to be effective. This method of application can almost completely apply the agent to the surface of the target plant without causing the liquid medicine to be thrown and dripping, and the utilization rate of the pesticide can reach 100%.
6, electronic computer application technology. The technology uses an electronic computer control system for an orchard sprayer that determines the shape of the fruit tree by an ultrasonic sensor so that the pesticide spray characteristics are automatically adjusted based on changes in the shape of the fruit tree. The electronic computer control system is used for pesticide application, which can greatly improve the work efficiency and the effective utilization rate of pesticides.
