Abstract: In order to clarify the key techniques of high-yielding and water-saving cultivations of upland hybrid rice, the field experiments were carried out in the regions along the Huaihe River. 5 upland rice varieties with high and stable yield, and 7 lowland rice varieties with water-saving and drought resistant traits were selected. Further, the key techniques of high-yielding and water-saving cultivations of upland hybrid rice Hanyou 73 were determined in the regions along the Huaihe River: the suitable seeding date ranged from June 5th to 12th, the optimum seeding rate was 2.0 kg/667 m2, the recommended application rate for nitrogen fertilizer was 10~14 kg/667 m2 and 40% nitrogen fertilizer as basal fertilizer, 40% nitrogen fertilizer as tillering fertilizer and 20% nitrogen fertilizer as earing fertilizer.

Key words: upland hybrid rice, high-yielding and water-saving cultivation techniques, region along the Huaihe River
