节水抗旱杂交稻旱优3号试种试验

旱优3号是我国南方首批通过省(市)级审定的节水抗旱杂交稻之一。2005年,从上海市农业生物基因中心引进广西试种,探讨其生态适应性、产量潜力及节水高产栽培技术。结果表明:旱优3号耐旱耐寒,中抗稻瘟病,高产优质,适应性广;一般单产6000.0kg/hm2,在高产栽培条件下,具有7500.0kg/hm2潜力;全生育期与特优63相仿,可作早稻、晚稻及中稻种植,在广西水稻旱区应用前景良好。

Cultivation experiments on water-saving and drought tolerant hybrid rice Hanyou No.3

Hanyou No.3 is one of the water-saving and drought tolerant rice hybrids which evaluated and approved firstly in the south of China.It was introduced from Shanghai Agricultural Biological Gene Center into Guangxi in 2005 to plant experimentally for investigating ecological adaptability and yield potential and exploring the cultivation techniques under water-saving condition.The results indicated that Hanyou No.3 was tolerant to drought and low temperature,resistant to rice blast,high yield with good grain quality,and wide adaptability.The grain yield reached to 6000.0kg/hm2 generally,and the yield potential may reach to 7500.00 kg/hm2 under high-yield cultivation conditions.The whole growth period is the same as hybrid rice Teyou 63.It can be planted as early rice,late rice and middle rice,so it is a promising variety in Guangxi rice drought area.
