Application of Laser Weeding Techniques in Upland Rice

Using of herbicide has caused a good many of serious problems such as environment pollution，decrease of biological diversity，changes in the weed community，and resistance of weeds to herbicides.As non-chemical weed management laser weeding method has been attracting more and more attention in recent years.Laser can quickly heat water of the plant cell and kill the plants.Laser weeding technology used in upland rice weeding field is of great importance.Based on weed control application research of laser weeding techniques in upland rice field，the current research progress on laser weeding has been analyzed and the problems of laser technology application in the field of weed control have been raised.Putting forward a laser weeding machine is used for weed control in the upland rice field，which mainly include laser part，field control part of the navigation and positioning and image recognition part.And problems are proposed in view of the present laser weeding research.
