除草剂变量施药技术的研究现状与进展

除草剂的田间大面积均匀喷洒不仅造成了浪费,而且加剧了环境污染,作为精确农业关键技术的除草剂的变量施药能够精确地对准杂草喷洒除草剂,从而有效地减少除草剂用量,降低了农业生产成本、减轻了环境污染压力。文章介绍了基于颜色、形状、纹理、光谱、位置特征的计算机视觉杂草识别技术;给出了变量施药技术的概念和介绍了变量施药技术的国内和国外的研究概况,并探讨了该技术的实施难点和未来研究发展方向。

Status quo and advance on research of variable-rate spraying technology

Traditional equable-spraying bring not only waste but also pollution, while the variable-rate spraying as a key technology of precision agriculture is effective and feasible because it can reduce the usage of herbicide, so it can decrease costs and lighten environment pollution. The paper introduced weed identification based on computer vision about color, shape, texture, spectrum and position; defined variable-rate spraying technology, summarized the achievement about this area in abroad and domestic, and also discussed its developmental prospect and difficulties in its enforcement.
