不同秧龄对杂交稻新两优香4产量的影响

Effect of Different Seeding Age on Yield of Xinliangyou 4

[目的]为水稻品种新两优香4筛选适宜的移栽秧龄。[方法]通过同期播种、不同秧龄处理,研究秧龄对水稻品种新两优香4产量的影响。[结果]随着秧龄的延长,新两优香4产量出现不同幅度的减产,尤其是当秧龄达49 d时减产幅度较大。[结论]新两优香4的秧龄弹性较好,其移栽秧龄在42 d以内时,对产量不会造成较大影响。

[Objective] The research aimed to screen the suitable seedling age for Xinliangyou 4.[Method] The effects of seedling age at transplanting on yield of Xinliangyou 4 were studied through sowing at the same time but transplanting at different seeding age.[Result] The of Xinliangyou 4 was reduced with the delay of transplanting time.When the seeding age was 49 days,the decreasing range was the highest.[Couclusion] The seeding age range of Xinliangyou 4 was wide,and had little effect on yield when it was less than 42 days.
