摘要
广两优676是福建省农业科学院水稻研究所利用广占63-4S与自选强优恢复系福恢676配组育成的籼型两系杂交稻新品种,分别于2013年和2014年通过国家和福建省农作物品种审定。2015年在湖北京山作一季稻示范7.05hm^2,平均每667m^2产量达800.9 kg。田间表现株叶形态好,群体结构理想,穗大粒重,较抗病虫。作超高产栽培技术主要有:统一播种,均播稀播培育壮秧;小苗移栽,拉线开厢浅插;适度密植,确保基本苗数;合理施肥,科学管水,及时晒田;综合防治病虫害。
Guangliangyou 676, a indiea two-line hybrid rice cuhivar, was developed from the cross of a hilinear male sterile line Guangzhan 63-4S and the optional strong restorer line Fuhui 676 by the Rice Research Institute at Fujian Academy of Agricultural Sciences, and it was registered and released for production by National and Fujian Province Crop Variety Appraisal Committee in 2013 and 2014, respectively. Guangliangyou 676 was demonstrated as single-cropping rice at Jingshan of Hubei province and a total of growing areas of 7.05 hm^2 in 2015, indicating the average yield of 800.9 kg per 667 m^2. 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 eultivation techniques included : uniform and sparse sowing, raising strong seedlings, transplanting at young seedlings, shallow growing with pull string and open compartment, moderately close planting, ensure basic seedlings, reasonable fertilization, scientific management water, timely exposing paddy field to sun, comprehensive prevention and control plant diseases and insect pests.
