潭原优4903是用潭原A与R4903配组育成的三系杂交迟熟早稻新组合。该组合具有株叶形态好、熟期适中、分蘖力强、产量高、抗性好、适应性广等特点,在长江中下游推广迅速。为此我们研究总结出了潭原优4903机插秧及高产栽培技术。 Tan Yuan Yu 4903 is a new combination of Tamura A and R4903 with three-line hybrid maturing early rice combination. The combination has the characteristics of good plant morphology, moderate maturity, strong tillering ability, high yield, good resistance and wide adaptability, and is popularized rapidly in the middle and lower reaches of the Yangtze River. To this end, we study summed up Tanhara 4903 machine transplanted rice and high-yielding cultivation techniques.
