Description
Technical field
The present invention relates to the equipment for plant protection technical field, especially relate to a kind of size variable formula space Droplet deposition proving installation and method of testing thereof, for use in testing for droplet distributing homogeneity and deposition on variable three dimensions in the tunnel type spraying.
Background technology
The garden crop of hedge wall type cultivation is thick with leaves, droplet is difficult to penetrate the fruit tree canopy and the deposition even, and often droplet stops that at the dense leaf curtain of skin lower gathering forms water droplet and tumbles loss, causes canopy inside and trunk disease and pest to can not get effective control.And, for spraying pesticide safely and effectively, optimal pesticide supplying effect is that spraying machine divides pesticide droplet equably and spreads on target, to guarantee the enough liquids of deposition on the crop leaf surface.Therefore the final index of weighing the spraying mechanical performance is the homogeneity of droplet deposition distribution on target in the spraying mechanical operation process.Space Droplet deposition and inhomogeneity accurate detection all have great importance to improving equipment for plant protection detection technique level, optimize the equipment for plant protection job parameter and improving the equipment for plant protection design level.
The tunnel type spraying is the novel pesticide application technology of developing for hedge wall type garden crop cultivation mode.Its principle is with the tunnel-type humidifier, that crop is semiclosed, and multi-faceted spraying simultaneously makes droplet more easily penetrate the crop top layer, in the crop inner vanes, forms better mist droplet deposition.Therefore the great advantage of tunnel type spraying is: increased the liquid uniform deposition, improved the agricultural chemicals utilization factor, reduced significantly pesticide drift and drippage.
Retrieval through the document to prior art is found, Chinese invention patent " horizontal fog scale distribution device and method of testing ", number of patent application 201110349996.3, provide a kind of horizontal fog scale distribution device and method of testing, realized the two dimension test of droplet on horizontal target.Patent of invention " spray amount vertical distribution method of testing and Special testing device ", number of patent application 200910027271.5, disclose the method for testing that a kind of vertical spray quantity distributes, and realizes the test of droplet in vertical distribution.Patent of invention " a kind of spraying Two dimensional Distribution automatic testing equipment and method ", number of patent application 201210472829.2, a kind of spraying Two dimensional Distribution automatic testing equipment and method based on ultrasonic sensor disclosed, control system is controlled the motion of two-dimensional movement unit at vertical and horizontal, the two-dimensional movement unit has test cell, has realized the test to the Two dimensional Distribution of liquid.But all there is defect in these methods, because spraying is a dynamic process, the droplet presentation space distributes, and has certain density liquid and carries out uniform fold, and single level or the vertical mist that carries out measure the distribution situation that examination can not illustrate mist amount reality.Need to carry out mist on space and measure the accuracy that the experiment of examination guarantee detects, thereby provide accurate reference for the running parameter adjustment of equipment for plant protection.Patent of invention " proving installation that a kind of mist quantity space of variable rate spray distributes ", number of patent application 201120565057.8, provide the mist of a variable rate spray to measure electricity testing device, this device utilizes with apertured cover plate mobile mist amount of testing diverse location on spraying face on collection mist groove, but method of testing is just measured spraying space mist amount, can not the actual deposition amount on crop leaf make test to liquid, and there is multidirectional coupling in the space mist amount data that this method of testing obtains, data processing complex, the result drawn is not directly perceived yet.
To sum up, the liquid of crop different growing stages sprays process and all is dynamic process, only tests the one dimension in certain growth period or the droplet space distribution of two dimension and can't disclose the actual deposition amount on crop leaf in the Dynamic spraying process.But therefore research and develop and a kind ofly can effectively measure the proving installation that tunnel type is sprayed at the comprehensive deposition effect of emulation Different Crop under job state or different growing stages, significant for correct evaluation tunnel type spray effect.

3. method of testing as claimed in claim 2 is characterized in that: the integrated evaluating method of the pulverability of same crop different growing stages:
Proving installation integrate the mist array as p * q * r, plant physical dimension according to a same crop n different growing stages, respectively width and the height dimension of space collection mist array are set, and each test in growth period is carried out to the test of m collection mist, gather the test result of its sprayed deposit amount, result is designated as A
ij, the matrix that wherein A is p * q * r, i is labeled as different growing stages, and j is labeled as the j time test; The mean value of its three times tests is:
Different growing stage spraying operation number of times or importance according to crop provide plant protection weight γ
1, γ
2, γ
3... γ
n(wherein weighted value should meet γ
1+ γ
2+ γ
3+ ... .+ γ
n=1); Calculate the three-dimensional deposition comprehensive evaluation of weighting of these spraying facility according to following formula: J=γ
1* A
1+ γ
2* A
