A hybrid rice cultivar Yiyou 673 was demonstrated as single-cropping rice at Yongsheng of Yunnan province with an altitude of 1420m and a total of growing areas of 9.03hm2 in 2011,indicating the average yield of 1005.85kg per 667m2.This cultivar was characterized by good plant type,rational population structure,large panicle and grain weight,and better resistance to disease and pests in the field.Key super high-yielding cultivation techniques included： breeding short and robust seedlings with right leaf age and more tillers,transplanting at young seedlings with shallow water,pull string,shallow growing and the space of 10cm×30cm in order to exceed 37.5×104 seedlings per hm2,applying sufficient basal fertilizers and accurate and quantitative dressing,scientific water management and pest control in time.
