Description
Technical field
The present invention relates to droplet density and size test device and its application method, belong to field of measuring technique.
Background technology
It is to be related to realize the spraying with certain mist droplet particle size and speed that liquid is sprayed.How to measure and control these important
The distributing homogeneity and density size of parameter are extremely important because these parameters be influence spray rear droplet movement locus and its with
The key factor that target organismses interact.For example, the effective force of specified chemical agricultural chemicals is frequently depend upon mist droplet particle size.It is excellent
, uniform target coverage rate spray and spray and obtain typically by small droplet, improve droplet heavy in target plant
Product rate method can reduce mist droplet particle size spectrum, while increase droplet velocities, wherein increase droplet fineness it is particularly important.However, compared with
Big droplet can keep its momentum with the long period, be not easily susceptible to the interference of crosswind, while being also less prone to be formed the drift of drop, such as spray
If spraying herbicide, droplet drift to neighbour can make plant or crop brings seriously, even destructive poisoning.Therefore, one
Preferable liquid drop spraying device is comprising narrower droplet spraying spectrum, both without very thick droplet, again without too thin droplet.Very
Study more and show, increase or keep spray droplet speed and corresponding momentum and kinetic energy can effectively reduce spray drift, and
Plant canopy permeability and deposition are improved, the waste of especially chemical pesticide is reduced, increased operation rate, meet national present
The target of " two subtract one increasing " that advocate.Transmission time of the drop between spray holes and target plant canopy and liquid drop speed are into anti-
Than slow mobile drop can be in the regional movement longer time between hat outside spray and plant, when droplet is stayed aloft
Between increase after, the possibility and probability that its drop is blown away are increased by, and utilization rate is significantly reduced.In addition, drop is in mesh
The deposition efficiency of plant is marked, especially the deposition efficiency of droplet, can be dramatically increased with the increase of liquid drop speed.
For China at this stage, the size of spray droplet, speed and quantity are not strict with during spraying pesticide, one
Point a little shower nozzles are second-rate, and the drop sprayed out is thick so that unit area fluid volume increases, and most of liquid is from target plant
It is lost in on biology, prevention effect is reduced, while polluting ecological environment.Dispenser spray particle diameter and speed are to determine spraying matter
The key factor of amount, should cause enough attention, go into overdrive to build the test platform of mist droplet particle size and speed.
The content of the invention
