With the progress and application of information technology in agriculture, precision farming (PF) has been increasingly gaining attentions in worldwide. PF technology is a kind of agricultural management system on the basis of the variability of spatial and temporal 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 PF. The current status of the acquisition information techniques of soil variability, the distribution of crop yield, diseases and insect pests and crop growth condition was analyzed, which showed that most of research focused on the acquisition and processing techniques of soil variability, most of the acquisition technique didn't realize the quick and real-time collection, and the single functional instrument was used. The development and research on the yield monitor system, the instrument for collecting timely soil parameter variability and integrating multifunctional information collection system will be the direction carried out in the future in China.
