摘  要：
简述了玉米精密播种技术在农业生产中的重要意义,指出采用精密播种技术是规模化生产实现节本增效的重要手段。从精密播种的不同功能实现角度,将玉米精密播种技术归纳为播种粒距均匀性控制技术和播深一致性控制技术两方面。详细阐述了保证播种粒距均匀的玉米单粒精密排种技术、种子平稳运移技术、种子精确定位技术和排种器驱动技术;分析了保证播深一致的必要性,阐述了播深一致性控制技术的研究历程。结合玉米精密播种技术国际研究动态,综述了玉米精密播种技术在智能化方面的最新研究进展,并结合我国生产现状指出了未来玉米精密播种技术的发展方向。

摘  要：
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.
