Effect of Different Seeding Ages on Yield of Xinliangyou 4

[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 production of Xinliangyou 4 was reduced with the delay of transplanting time.When the seeding age was 49 days,the decreasing range was the highest.[Conclusion] Xinliangyou 4 had wide range of seeding age and little effect was put on yield when the days were less than 42.
