In order to screen high-efficiency herbicides for wheat field buckwheat, researchers from the College of Plant Protection of Shandong Agricultural University used laboratory bioassay to study the herbicidal activity of 13 herbicides on buckwheat and the field efficacy test of 5 herbicides. The results showed that at the low dose recommended in the field, 7 kinds of weeding such as flufensulfuron, acesulfame, flufenacet, methyl disulfuron, isoproturon, sulfonylsulfuron and propylsulfuron The agent has high control effect on buckwheat, and the 21-day fresh weight inhibition rate is 88.30%, 86.32%, 83.97%, 78.47%, 76.76%, 72.83%, 71.39%, and the 21-day fresh weight inhibition rate at high dose. Up to 98.57%, 95.36%, 91.58%, 91.46%, 89.47%, 82.48%, 82.20%; the efficacy of each dose of flucarbazone was higher than other herbicides. Six herbicides such as pyrimethoxam, oxafluridone, clodinafop, flufenacetate, oxazolin, and oxazolidine were less effective against brome. Field efficacy trials of five herbicides, such as flufensulfuron, acesulfame, flufenacet, methyl disulfuron and isoproturon, showed that flufensulfuron had the highest control effect on buckwheat at high doses. The control effect of the 20-day strain was 85.04%, and the control effect and fresh weight control effect of the plant were 83.94% and 84.17%, respectively. There was no obvious phytotoxicity in wheat. The recommended dosage in the field was 21.00～42.00 g(ai). /hm2. The above studies showed that the sensitivity of buckwheat to different herbicides was different. Among the 13 herbicides tested, flufensulfuron was the most effective and safe for buckwheat, and it was an ideal herbicide for controlling buckwheat.

It is used to control the movement of various mechanical systems, such as valves, dampers, and other industrial equipment. Electric actuators are commonly used in industrial applications where precise positioning, speed control, and high accuracy are required. They are also used in the automotive industry, aerospace industry, and medical equipment. Electric actuators are available in different types, including linear actuators, rotary actuators, and multi-axis actuators. They can be powered by AC or DC power sources and can be controlled by various types of controllers, such as programmable logic controllers (PLCs) and human-machine interfaces (HMIs).
