Maize could be used as food, animal feed, as well as industrial materials, so it has become to be the most important crop all over the world. The potential yield of maize is more than 27 mt/hm2, but the statistical data from FAO shows that farmer’s actual average yield is only one fourth of that. Precision planting is one of an effective method to increase maize yield，so as to decrease this gap. Precision planting technology has a critical effect on agricultural production and is the key to decrease cost and increase benefit for scaled farmer’s production, international machinery companies are paying more and more attention and investing a lot on invention or innovation of precision planters,so new precision planting technologies and devices, such as high speed metering systems, down force depth control units, are developing very fast, and they are widely accepted and used by individual farmers in the world. According to the various functions realized by precision planting, precision planting technologies were classified into the following categories: control technology of seed spacing uniformity, control technology of sowing depth uniformity, and intelligent integration of precision planting. On the seed spacing uniformity, technologies of single seed sowing, seed delivery and seed monitoring were elaborated. The significance of sowing depth uniformity was analyzed, and its development process was generalized. In terms of the application in intelligence, a comprehensive review of the existing research advances was presented. Finally, the development direction of precision planting technology was pointed out based on the current situation of China.
