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.
