Research on Production Demonstration of a Hybrid Rice Teyou269 and its High Yield Cultivation Technology

Teyou269 is new varieties hybrid rice line-bred by Yulin Research Institue of Agricultural Sciences.It was certified and registered by Guangxi Committee for Crop Variety Registration in June,2012. In 2012, 7.09 hm2 demonstration area of high yield cultivation of Teyou269 at spring was conduted in Ronglou Village of Maolin Tow, Yndong District. In the demonstration process, a series of cultivation measures were applied, for example： timely early sowing and tin sowing were applied to cultivation strong seeding, seedings were transplanted timely to obtain lower tiller, and balanced fertilization and timely top dressing were done. Moreover, the scientific irrigation and drainage was applied and the disease and insects pest were controlled. For these measures, the average yield of Teyou269 reached 11.13 t/hm2.
