Maize can be used as food, animal feed and industrial raw material. The increase in maize yield is of great value to support growing population in the world. At present, it is widely planted around the world, and maize planters are generally adopted in the seeding process. Because cultivatable field is limited, increasing the yield per area is the only way to increase the whole yield. Precision seeding is an effective method to increase the yield. However, the precision that mechanization contributes to the seeding has been maximized. In order to further improve the seeding precision, intelligent technology has gradually been used on maize planters. For domestic planters, it is relatively high on the mechanization level, but it is low on the intelligent level. Maize planters play important role in the seeding process, however, people still have to play a part in monitoring the state of planters. It is not only laborintensive, but also lacking of precision. Therefore, intelligent technologies must be fully used to replace the human labor. The seeding process can be classified into metering process, transporting process and landing process. From this perspective, the working principle, technical feature and developing situation of seeding technology and its measurement and control technology applied to maize planters were described. On the basics of analyzing and generalizing all advantages and disadvantages of seeding technology, the developing trends of seeding technologies were prospected, and the new demands about maize seeding technologies in the background of precision agriculture were predicted.
