摘要
[目的]研究小麦不同收割期对小麦产量及千粒重的影响,探寻最适收割时期.[方法]试验设10个收割时期,随机收割3个小区,共6 m2,单打单收,测实产和千粒重.[结果]通过试验可知,以小麦蜡熟末期前后3d时间收割,产量最高,收获期为最适.[结论]适时收割对小麦产量影响明显,以小麦蜡熟中期和末期为最佳收获期,此时产量为最高,品质最好.
Abstract
[Objective] To research the effects of harvesting period on the yield and thousand-grain weight of wheat, and to find the optimal harvesting period.[Method] Ten harvesting periods were designed in the test;and three plots were randomly harvested with in all six square meters.The yield and thousand-grain weight were measured.[Result] The maximum yield appeared when wheat was harvested on three days before or after late ripening stage.[Conclusion] Timely harvesting has significant impacts on wheat yield.Middle and late ripening stage of wheat is the optimal harvesting period, which has the maximum yield and highest quality.
