激光除草技术在陆稻田间的应用研究

Application of Laser Weeding Techniques in Upland Rice

除草剂的广泛使用引发了环境污染、生物多样性减少、杂草群落变迁和杂草抗药性等诸多问题。激光能够快速加热植物体内的水分使植物细胞破裂死亡。通过对激光除草技术在陆稻田间除草应用的研究,分析了激光除草技术在农业中的应用现状和激光技术应用于田间除草亟待解决的问题,给出了一种应用于陆稻田间除草的激光除草系统,主要包括系统控制部分、田间定位导航部分和图像识别部分。最后针对激光除草研究的问题提出了建议。

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.
