中国杂交水稻在巴西的试种表现及高产栽培技术

Experimentation of Chinese Hybrid Rice in Brazil and Its High-yielding Cultivation Techniques

2011年9月至次年2月,隆平高科选择6个中国杂交水稻组合在巴西戈亚斯州北部Araguaia流域进行了品比试验,结果 6个组合单产为8.07～9.15 t/hm2,比当地对照品种Puita增产36.1%～54.3%。结合当地水稻生产实际,从品种选择、发运、整地、种子处理、播种、田间肥水管理、综合防治病虫草鸟害等方面介绍了中国杂交水稻在巴西的高产栽培技术。

During September, 2011 and February, 2012, Yuan Longping High-Tech Agriculture Co. Ltd. intro- duced 6 Chinese hybrid rice varieties into Brazil to conduct a yield trial in Araguaia, Goias with Puita, a local im- proved rice variety, as the control. The results showed that the average yields of the tested hybrids ranged from 8.07 to 9.15 t/hm^2, 36.1% and 54.3% higher than that of the local check Puita. Based on the local conditions, the high-yielding cultivation techniques, including variety selection, seed export and transportation, land prepara- tion, seed treatment and sowing, field management in irrigation and fertilization and integrated pest control, were proposed for hybrid rice production in Brazil.
