针对安徽沿淮地区气候特点，通过试验筛选出适宜沿淮地区旱种旱管栽培，丰产性和稳产性较好的旱稻品种5个，节水耐旱型水稻品种7个；明确了沿淮地区以旱优73为代表的杂交旱稻的丰产节水栽培技术：播种期6月5-12日，播种量2.0 kg/667 m2左右，氮肥用量10~14 kg/667 m2；在施肥过程中适当降低基蘖肥用量、增施穗粒肥，基、蘖、穗肥比例以4∶4∶2较好。

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.
