experimental wind tunnel for agricultural spraying process (1) for the study of the interactions between the effectiveness of pesticides and the risks they represent the environment and public health under conditions of controlled

摘要

the wind tunnel experiment for agricultural spraying (sepa) is a laboratory constructed to study under conditions of controlled interaction between the efficiency and the risks they preu00e9sentent pesticides on health and the environment publisque.the amount of pesticide lost during and after the treatment of crops caused major damage at all levels established by hundreds of studies from around the world.the blower 1 is to examine the area effect of spray parameters and weather conditions on the amount of chemical product lost to compartments in the context.the advantages of this laboratory is to provide outlis predicting losses of pesticides into the air, soil and water as well as the retention on plants in the chemical treatment under specific conditions. this will allow users to.choose the most favourable conditions for the proper management of environmental risk before taking action. the development of a comprehensive treatment after surgery, and 3. to find a compromise between efficacy and for the preservation of the environment for the various parameters involved in the games.during the work, we can measure at the same time the retention on the parties, the drift (transfers to the air) and the loss of soil and water on the parameters) by varying the power.the climatic conditions are controlables in broad ranges: wind speed: 1 to 10 m / s, 10 to 90 degrees - temperature - relative humidity: 30% to 100% in the mobile spray rail tunnel.powered by a self-propelled spray it, it can control the parameters for the machine nozzle, pressure, speed and height. the test area is a section of 5mx2m (lsl).the physical parameters of the adjustable movable ramp is in exactly the same way as for the spray nozzle in the field: type, size, number and spacing of working pressure working height of the rail haulage speed of the machine for different types of the measures, it is possible to use real or a substituent (e.g., pesticidestractor, using real manifolds (e.g. plants) or artificial.
