摘要
2011年杂交稻新品种宜优673在海拔1 420 m的云南永胜作一季稻示范9.03 hm2,平均产量达1 005.85 kg/667m2。田间表现株叶形态好,群体结构理想,穗大粒重,较抗病虫。超高产栽培技术主要有:培育适龄多蘖矮壮秧;小苗移栽,浅水拉线浅插,适度密植(10 cm×30 cm)以下,确保基本苗数37.5万/hm2以上;施足底肥,精确定量追肥;科学管水,及时防治病虫害。
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.
