Background

Rice is the main economic crop in China. The rice planting is not only one of the main grain crops in China, but also is an important guarantee for the life and development of the masses in China. The planting of rice and the technical development and application thereof greatly promote the genetic breeding process of crops. In rice planting, the control of weeds in the field is the key point for obtaining high yield and high quality in rice planting. The weeds in the field have multiple harmfulness to rice, key weeding factors are not mastered in place, and a series of problems can be caused if the weeds cannot be protected and prevented in time, so that the yield of the rice is reduced, and the weeds stretch. When the weeds in the paddy field are not weeding in time, the weeds can grow too vigorously to compete for fertilizer and water with seedlings, so that the yield and the quality of the paddy rice are reduced. Most of the existing rice weeding technologies adopt pesticides to remove weeds, the pesticides have toxicity and residue in different degrees, part of pesticide residues can be accumulated in rice grains, and the pesticides can be remained and accumulated in soil to cause damage and pollution to human bodies and soil. In order to ensure the safety of food and land, people should encourage manual or mechanical weeding and use less pesticide, but because labor is reduced, labor cost is increased, and the operation of a tool is simple or difficult during mechanical weeding, weeds on the side wall of the field cannot be cut off in the mowing process, so that the enthusiasm of people for using the tool is restricted.
