精细农业中农情信息采集技术的研究进展

由于现代信息技术在农业中的应用，精细农业在世界范围内引起了广泛关注。快速有效地采集和描述影响作物生长环境的空间变量信息，是开展精细农业实践的重要基础。围绕土壤环境、作物产量分布、病虫草害及作物长势等信息采集技术的研究情况进行了阐述，指出了现有采集技术存在的优缺点，并在此基础上指出提高设备的采集精度和速度，开发研制产量监测系统、土壤环境信息快速测量仪以及多功能采集设备是近阶段的主要研究方向。

Research progress in farming information acquisition technique for precision agriculture

With the progress and application of information technology in agriculture, precision agriculture has been increasingly gaining attentions worldwide. The precision agriculture technology is a kind of agricultural management system on the basis of spatial and temporal variability of crop yield of small section and circumstance factor in the field. To measure timely and efficiently the spatial and temporal variant information that influences crop production is the key step for implementing precision agriculture. The current status of the acquisition parameter techniques of soil variability, the distribution of crop yield, diseases and insect pests and crop growth condition was reviewed and analyzed in this paper. It is pointed out that the development and research of the yield monitoring system, the instrument for collecting timely soil parameter variability and integrating multifunctional information collection system will be the developmental trend carried out in the future.
