Problems solved by technology

The spray effect test of the traditional sprayer is mainly carried out by the density distribution method of chemical dyeing liquid droplets. This method can only be tested on a single plane, and due to the good solubility of dyes and water, this method is difficult to measure three-dimensional Confirmatory test of spray effect

Abstract

The invention relates to a method for testing the spray effect of a sprayer by using Nomuraea rileyi spores, and belongs to the technical field of performance test of agricultural production equipment. The method includes the following steps of: adding Tween80 to an aqueous suspension containing the Nomuraea rileyi spores, performing ultrasonic concussion, adding water, and uniformly mixing to obtain a test solution; adopting a tested sprayer to spray the test solution towards the front sides and back sides of leaves of plants of the same variety at different distances and angles, after the surfaces of the leaves of the plants are naturally dried, collecting the sprayed plant leaves, washing the plant leaves with purified water, performing microscopic examination and counting on washing liquid under a microscope, and calculating the number of the spores per unit area. The comparison method of the spray effect of different sprayers is that: under the same spray conditions, once the number of the attached spores becomes larger, better spray efficiency and uniformity can be achieved. The scheme of the invention has the positive effects that: the verification test of the three-dimensional spray effect is carried out in the actual production process, and the result is more objective and reliable.

Description

technical field [0001] The invention belongs to the technical field of performance testing of agricultural production appliances, in particular to a method for testing the spray effect of a sprayer. Background technique [0002] Modern agricultural production has a greater dependence on pesticide sprayers. From the application of drugs and fertilizers to the promotion of precision sprinkler irrigation, there are high requirements for the application effect of sprayers. The spray effect test of the traditional sprayer is mainly carried out by the density distribution method of chemical dyeing liquid droplets. This method can only be tested on a single plane, and due to the good solubility of dyes and water, this method is difficult to measure three-dimensional Confirmatory testing of spray effects. Contents of the invention [0003] The object of the present invention is to aim at the shortcoming of prior art, provide a kind of method that utilizes Nomura spores to test sp...
