The invention discloses a method for testing the spraying effect of a sprayer by nutilizing spores of Nomuraea Rileyi, belonging to the technical field of performance ntesting of agricultural production equipment. Adding Tween80 into the aqueous nsuspension that contains the spores of Nomuraea Rileyi, and applying ultrasonic nagitation, and then adding water and mixing to obtain the test solution. Spraying the ntest solution on the same variety of plants at different distances with angles towards nthe front and back sides of the leaves, collecting the sprayed plant leaves after they nhave dried naturally, washing them with pure water, taking the washing liquid and ncalculating under a microscope for the number of spore per unit area. The method of ncomparing spraying effects of different sprayers is that the lager number of attached nspores observed means the spraying effect is more efficient and evenly. Positive neffects of this inventions is to verify three-dimensional spraying effect in the actual nproduction process, and the result is more objective and reliable. |
