摘　　要：[目的]研究399对"一种两收"再生稻的影响。[方法]以适宜丘陵红黄壤种植的丰两优香1号、准两优527、宜优673再生稻品种为材料,分别设置喷施399和不喷施399(CK)2种处理,研究各处理对再生稻根系和产量的影响。[结果]结果表明:施用399使水稻在生育期上延缓成熟,且施后再生稻的总根系数量、白根数量、根鲜重、根干重、根体积大幅度增加,同时在两季总产量上准两优527、丰两优香1号和宜优673品种分别比对照增产6.39%、4.86%、5.94%。[结论]施用399有利于准两优527、丰两优香1号和宜优673再生稻品种再生根的发生。[Objective] Impact of 399 on roots and yield of ratooning rice was studied.[Method]Taking Fengliangyouxiang NO. 1,Zhunliangyou 527,Yiyou673 as materials which were suitable for cultivation at hilly red yellow soil zone. There were two kinds of processing such as spraying 399 and no spraying 399（ CK）. [Result] The results showed that spraying 399 can delay maturity of rice in the growth period,and the total number of roots,white roots,etc. increased significantly. The total output of Zhunliangyou 527,Fengliangyouxiang NO. 1 and Yiyou673 varieties was increased by 6. 39 %,4. 86%,5. 94% respectively. [Conclusion]Spraying 399 was advantageous to the occurrence of ratooning rice varieties（ Zhunliangyou 527,Fengliangyouxiang NO. 1 and Yiyou 673） to take root.
