Research on Device and Sensing Technology for Precision Seeding of Potato

The potato industry is crucial to the development of the agricultural economy, and mechanized seeding is an effective aid to its modernization. Due to the metering devices having different sizes and structures, and even control, operation of sudden instability and other characteristics, and the complexity and variability of the farmland environment and other reasons, the mechanical sowing process may be affected by internal and external random and unpredictable factors, thus causing seed potato leakage, reseeding, and other phenomena and resulting in a decline in the quality of potato sowing brought about by the cascade effect: the quality and yield decline, precision sowing has become the modern potato production in the problem of modern potato production needs to be solved. This paper reviews the potato planter around the seeding quality of single seeding, plant spacing, depth and other directions of device optimization and digital sensing technology innovation involved, which single seeding direction from a variety of metering devices and the use of other sowing methods of potato planter detection, replanting, metering and other parts of the entry, and the introduction of the other field crops crop related research to provide a more comprehensive perspective. The advantages and disadvantages of the related research were compared and the existing problems were analyzed, and the future development direction of potato precision sowing technology was prospected.
