The present invention discloses a weeding activity zoning test device for 4, 8-DHT herbicide. The device comprises a box body and a supporting assembly, the box body comprises a shell and a tray, a heating lamp is installed at the top of the shell, a threaded hole is formed in the side portion of the shell, a water inlet pipe is installed in the threaded hole in a threaded mode, a water outlet pipe is installed at one end of the water inlet pipe in a threaded mode, and an inserting groove is formed in the tray; the bottom edge of the shell is slidably inserted into the inserting groove, a groove is formed in the upper surface of the tray, and a leakage pipe is installed in the tray in a threaded mode; the supporting assembly comprises a supporting table, directional wheels, universal wheels and a bottom plate, a strip-shaped hole is formed in the upper surface of the supporting table, a dragging rod is fixedly connected to the inner wall of the strip-shaped hole, the tray is placed on the dragging rod, the universal wheels and the directional wheels are all installed at the bottom of the bottom plate, and a discharging port is formed in the side portion of the supporting table. According to the invention, the herbicidal activity of the herbicide in different application modes and at different temperatures can be observed, and more comprehensive test results can be obtained.
Description
technical field [0001] The invention relates to the technical field of herbicide herbicide activity test, in particular to a herbicide activity sub-area test device for 4,8-DHT herbicide. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have a deadly effect on any kind of plants, and their effects are affected by three factors: herbicides, plants, and environmental conditions. According to the function, it can be divided into killing and selective herbicides. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum, and low dosage, and disposable tre...
