The invention relates to the technical field of agricultural machines, in particular to a corn precise localization synchronal sowing control system. The corn precise localization synchronal sowing control system comprises a fertilization flow control system, a fertilization amount detecting system, a fertilizer depth measuring device, a fertilizer soil entering detector, a sowing control system, a sowing position positioning system, a seed depth measuring device and a seed soil entering detector, wherein the fertilization flow control system, the fertilization amount detecting system, the fertilizer depth measuring device and the fertilizer soil entering detector are arranged on a fertilizer feeding device, and the sowing control system, the sowing position positioning system, the seed depth measuring device and the seed soil entering detector are arranged on a seeding device. The fertilization amount detecting system is used for detecting the fertilization amount of all sowing points, the fertilizer soil entering detector is used for detecting the fertilizer soil entering time, the fertilizer depth measuring device is used for measuring the actual sowing depth of fertilizer, the sowing control system is used for controlling sowing time, the sowing position positioning system is used for carry out statistic at the positions of all the sowing points, the seed soil entering detector is used for detecting the seed soil entering time, and the seed depth measuring device is used for measuring the actual depth of seeds. The data are stored into a memorizer and are transmitted to a background server through a wireless transmission device.
