杂交稻新品种旱优3号耐旱性研究

Study on Drought Tolerance of Hybrid Rice New Variety Hanyou 3

[目的]了解杂交稻新品种旱优3号的耐旱能力。[方法]分别进行田间试验和盆栽试验,均设水管栽培(CK)、旱管栽培和耐旱栽培3个处理。[结果]不管是大田栽培还是盆栽,旱优3号的3种水分管理模式均以旱管栽培产量最高,耐旱栽培最低。该品种在大田试验中耐旱栽培比水管栽培减产5.5%,在盆栽试验中耐旱栽培比水管栽培减产达43.1%。[结论]旱优3号在南充当地对水分有一定的敏感程度。

[ObJective] The aim was to understand the drought tolerance of hybrid rice new variety Hanyou 3. [Method] Tile tests were conducted in field and pot, which were cultivated with water management （CK）, dry pipe cultivation and drought cultivation. ]Result] Whether it was in the fieht or pot, Hanyou3 had the highest yield with th7 pipe cultivation, anti had the lowest yield with drought cuhivation. In fiehl test, the yield of Hanyou 3 in drought cultivation decreased 5.5% than the yield in cultivation with water management. In pol test, the yield of Hanyou 3 in drought eultivation decreased 43.1% than the yiehl in cultivation with water management.[Conclusion] Hybrid rice new variety Hanyou 3 had a certain degree of sensitivity on water in Nanchong.
