不同播种期对同德无芒披碱草鲜草和种子产量的影响

Effects of Different Sowing Dates on the Fresh Grass and Seed Yield of Elymus submuticus Keng f. Tongde

[目的]研究播种期对同德无芒披碱草鲜草和种子产量的影响。[方法]在青海省牧草良种繁殖场,分8个播种期对同德无芒披碱草进行播种,研究不同播种期对同德无芒披碱草鲜草和种子产量的影响。[结果]播种期为6月10日的同德无芒披碱草的鲜草与种子产量综合表现最好,播种期与鲜草、种子产量无明显关系。[结论]同德无芒披碱草的最佳种植时间为6月上旬。

[Objective]To study the effects of sowing date on the fresh grass and seed yield of Elymus submuticus Keng f.Tongde.[Method]8sowing dates were designed to sow Elymus submuticus Keng f.Tongde at Qinghai Forage Seed Reproduction Farm.The effects of different sowing dates on the fresh grass and seed yield of Elymus submuticus Keng f.Tongde were studied.[Result]The fresh grass and seed yield of Elymus submuticus Keng f.Tongde in treatment⑤(sowed at June10)were higher,sowing dates had no obvious relationship with its fresh grass and seed yield.[Conclusion]The optimum sowing date of Elymus submuticus Keng f.Tongde was early June.
