The device comprises a nozzle mast type pesticide application system, an atomization type pesticide application system, a rising and falling adjustment system and a pesticide application system supporting frame, wherein the nozzle mast type pesticide application system is located on the upper portion of high-canopy-density crops to achieve large-droplet-diameter nozzle mast type pesticide application which does not cause drifting easily, and the atomization type pesticide application system is located on the lower middle portion of high-canopy-density crops to achieve ultra-small-droplet-diameter atomization type pesticide application which can achieve uniform diffusion easily; the nozzle mast type pesticide application system and the atomization type pesticide application system are fixed and supported by the pesticide application system supporting frame, and nozzle mast type pesticide application height and atomization type pesticide application height are adjusted by the rising and falling adjustment system so as to adapt to pesticide application requirements of crops in different heights. By the adoption of the device and method, on the premise that the effect of uniform deposition of pesticide liquid is guaranteed, power consumption and droplet drifting risks of a sprayer are reduced, the effective utilization rate of pesticide liquid is increased, crop pest control effect is improved, and environment pollution is reduced.
Description
Technical field
The invention belongs to technical field of plant protection machinery, relate to a kind of compound device for administration of drugs and the method that are suitable for high crown density crop, be particularly useful for cotton, the medicament such as the extermination of disease and insect pest or defoliant of seeding corn and other crops middle and later periods when forming high crown density canopy spray.
Technical background
Land for growing field crops crop pest control all adopts common spray rod type spray pattern mostly.The extermination of disease and insect pest of spray rod type spray pattern to the crop seedling phase is more effective.But modern agriculture requirement rational close planting is to improve output, but dense planting plant growth is to the middle and later periods, define high crown density canopy.
When crop grow into the middle and later periods form high crown density canopy time, if still adopt single spray bar type spraying machine tool, owing to being subject to the stop of dense canopy, first droplet cloud is intercepted and captured by dense top layer blade, do not continued inwardly to penetrate by the droplet intercepted and captured, but do not successively decreased by the droplet amount intercepted and captured, in plant internal layer deposition far below plant superficial deposit rate, occur " mist droplet deposition decay " phenomenon.
The appearance of " mist droplet deposition decay " phenomenon causes only having a small amount of liquid can deposit to canopy lower target and puts on, and the excessive fluid loss of canopy upper strata deposition is in soil, affect the extermination of disease and insect pest effect of crop, reduce the effective rate of utilization of agricultural chemicals, pollution of ecological environment.Increase formulation rate and worsen mist droplet deposition harmony on plant branches and leaves on the contrary.The dispenser of high crown density canopy has become the bottleneck problem in chemical control.
Atomizing droplet aloft suspension time is long, is easily caught by target organisms, has good penetration performance, but as easy as rolling off a log be subject to nature wind action produce drift.Air assisted spray mode is can secondary-atomizing, reduces fogdrop diameter distribution, changes local canopy porosity again, form vent flow path by forced draft, by carrying droplet secretly, easily forms the deposition of crop inside.In dispenser for high crown density canopy crop, air assisted spray mode can reduce " mist droplet deposition decay " phenomenon to a certain extent.But air assisted spray is in order to realize, and droplet is anti-to waft and changes plant local branches and leaves porosity, and need blower fan to form very large blast, air quantity and wind speed, therefore in air assisted spray, blower fan defines maximum power consumption.
Therefore, for high crown density canopy crop pattern feature, less and the comprehensive extermination of disease and insect pest device for administration of drugs of " mist droplet deposition decay " problem can be suppressed in the urgent need to inventing a kind of power consumption, make that liquid droplet deposition uniformity is good, pesticide efficacy is high has important practical significance.
Through finding prior art literature search, Chinese invention patent " self-propelled pesticide spraying machine suspender spraying device ", application number 201110167637.6, provide a kind of self-propelled pesticide applicator suspension rod sprayer unit, by arranging shower nozzle respectively on sprayer unit bracket institution and suspension rod, realize preventing and treating the damage by disease and insect at each position, long-stalked crops the middle and late growth stage upper, middle and lower.But this patent is not owing to applying air-flow aid in administration, the therefore anti-poor-performing that wafts of its dispenser droplet above crop canopies; In crop, the diffusion of lower floor's dispenser droplet is poor.And use the distribution of same fogdrop diameter due to the shower nozzle arranged on bracket institution and suspension rod, therefore its anti-performance and penetration performance of wafing can not be unified, thus is difficult to have best deposition properties.
