摘　　要：概述了国内外化肥深施研究的发展状况;介绍了基肥深施、种肥深施、追肥深施3种化肥深施形式的操作要点,及化肥深施的增产增收机理;以实例列举了化肥深施在水稻、小麦、玉米等主要农作物上应用的增产增收效果,最后展望了农艺农机结合的化肥定位深施肥技术发展前景。The overview of deep-applying fertilizer in China and abroad was simply expounded. Then, it detailedly introduced the key operating points of three deep-applying fertilizer methods (deep-applying base fertilizer, seed manure and top dressing), and the yield-increasing and income-increasing mechanism of deep-applying fertilizer. Meanwhile, it put forward the yield-increasing and income-increasing effects of applying deep-applying fertilizer in main crops (rice, wheat and maize). In the end, it prospected the future of locating deep-applying fertilizer combined with agricultural machinery and agricultural technology.
