Device for metering retention quantity change of spray medicine liquid on surface of plant leaf

Abstract

The invention relates to a device for metering the retention quantity change of a spray medicine liquid on the surface of a plant leaf, which comprises a glass cover, an electronic balance, a leaf carrier, a leaf carrier supporting rod, a leaf carrier pedestal and a flare casing tube, wherein the electronic balance is placed inside the glass cover, and the leaf carrier pedestal is placed on the electronic balance; a small hole is arranged at the top of the glass cover, and the leaf carrier supporting rod is inserted into the leaf carrier pedestal to be supported after penetrating through the small hole; the leaf carrier is fixed on the top of the leaf carrier supporting rod, the flare casing tube is buckled on the upper surface of the glass cover and is sleeved outside the leaf carrier supporting rod, and the inner wall of the flare casing tube is loosely matched with the leaf carrier supporting rod. By using the metering device, the retention quantity change of the spray medicine liquid on the surface of the plant leaf can be metered. Compared with the method for directly immersing the leaf in the medicine liquid, the device provided by the invention can be used for testing the retention quantity of the medicine liquid, the simulation process coincides with the fact, and the simulation result is genuine and believable.

Description

technical field [0001] The invention relates to a simple metering device for changing the retention amount of medicinal liquid on the surface of plants, in particular to a simple metering device for changing the retention amount of medicinal liquid on the surface of plants in a spray state, and belongs to the technical field of pesticide use. Background technique [0002] In order to control harmful organisms that harm crops, pesticides are often used in farmland. The most common method in the use of pesticides in our country is to use different spraying equipment for pesticide field spraying. The retention capacity of pesticide solutions with different physical and chemical properties on different plant surfaces is different. Since the retention capacity of various plants for different pesticide liquids is not clear, it can often be seen that the amount of sprayed liquid exceeds the maximum retention capacity of the target plant surface and a large amount of water is lost....

AI Technical Summary

Problems solved by technology

If the leaves are directly immersed in the liquid medicine, the surfactant in the liquid medicine is more likely to transfer to the new interface, and it is easier to wet the leaves, so that the retention of the liquid medicine on the surface of the leaves is relatively large, which cannot correctly reflect the medicine under field conditions. Retention capacity of liquid on target plant surface
