Six techniques for applying pesticides
For the control of crop diseases, insects, grasses and rodents, integrated control techniques should be adopted. When pesticides are used for prevention and control, pesticides should be selected at the same time. In the appropriate application period, the correct application method should be adopted, and the economical and effective dosage of pesticides should be applied. The dosage of pesticides and the method of application should not be arbitrarily increased.
Electrostatic spraying electrostatically sprays droplets through high-voltage electrostatic generators. The amount of deposited droplets on the surface of the blades is significantly increased, which can increase the effective utilization of pesticides to 80%. The disadvantage is that the penetrating ability of the canopy of the plant with charged droplets is weak.
Recycling spray is equipped with a drug recovery device on the conventional sprayer to collect the liquid that has not been deposited on the target plant and then pump it back to the liquid tank for recycling. This can greatly increase the utilization of pesticides.
The computer controls this technology to spray technology on the basis of modern electronic computer control technology, the use of photoelectric elements as sensors, when the nozzle "discover" the target when the liquid is ejected, otherwise the nozzle stops spraying. This technology greatly improves the effective utilization of pesticides.
Pellet Dispensing Pills can be applied to water-soluble pharmaceuticals that are used in paddy fields. Just pour the pills evenly into the fields. Not only does it improve productivity more than ten times, and there is no pesticide drift and no pollution to neighboring crops.
Roller coating is mainly used for the use of systemic herbicides. Using a foam material that can absorb liquid chemicals, it is made of a wiper roller. The liquid solution seeps out through the surface of the roller. It only needs to touch the blade on the upper part of the weeds. This method can almost completely exert the agent on the target plant, and no liquid spillage or dripping occurs.
Deep application of medicinal fertilizers This application technology is mainly aimed at pests and soil-borne diseases that harm underground rhizomes, such as cockroaches, cockroaches, beetles and root rot, and root rot. These pests and diseases, appendages such as mulch and greenhouses, etc., are difficult to work with the method of spraying on crops and leaves on the ground. Only by applying the medicinal fertilizers in depth to a certain stratum and site can the effectiveness of control be reduced, pollution can be reduced, and the key can be hit. However, in order to enter the land in depth, in the past, the pharmacy had to be manually plugged into the roots and strata of crops. This was not only inefficient but also had direct contact with pesticides. It was not safe for humans. Therefore, it was necessary to apply hand-powdering tools such as fertilizer-spraying guns. Safe and convenient.
