摘　　要：以节水抗旱稻旱优73为再生稻栽培,与丰两优香1号作对比,比较在旱管、水管条件下产量和经济效益的差异。结果显示,在旱管条件下旱优73头季产量显著高于丰两优香1号,而再生季产量显著低于丰两优香1号,总产量相当,与水管条件下结论一致。经济效益方面,旱管与水管条件下旱优73略低于丰两优香1号,差异不显著。综合来看,旱优73在江汉平原可以作为再生稻品种利用,特别是在干旱气候条件下更能体现出其产量及经济效益优势。Compared with Fengliangyouxiang No.1,the water-saving and drought resistant rice Hanyou 73 was cultivated as ratoon rice,and the difference of yield and economic benefit under dry and water pipe conditions was compared.The results showed that the yield of Hanyou 73 in the first season was significantly higher than that of Fengliangyouxiang No.1 in the dry management condition,while the yield in the regeneration season was significantly lower than that of Fengliangyouxiang No.1,and the total yield was the same,consistent with the conclusion under water pipe condition.In terms of economic benefits,Hanyou 73 was slightly lower than Fengliangyouxiang No.1 under dry management condition,and water pipe condition.There is no significant difference between the two.In conclusion,Hanyou 73 can be used as ratoon rice variety in Jianghan Plain,especially in arid climate.
