[目的]探索不同谷子品种的最佳播期,对谷子产量、农艺性状及抗性进行测定。[方法]采用裂区试验,主区为播期,副区为品种,研究了播期对谷子产量、农艺性状及抗性的影响。[结果]试验结果表明,早播或晚播均会造成减产;参试品种长生07、晋谷36、长农35产量较高。结合产量、农艺性状、抗性,长生07、晋谷40、晋谷36适宜的播期为5月13日,延谷13、长农35适宜的播期为5月20日。[结论]延安谷子适宜播期为5月10~20日。
[Objective] The research aimed to explore the optimum sowing dates of different millet varieties, and to determine the yield, agronomic traits and resistance of millet. [Method] With the split zone experiment, the main area was sowing date and the secondary area was the variety. The effects of sowing date on the yield, agronomic traits and resistance of millet were studied. [Result] The results showed that either early sowing or late sowing resulted in the decrease of yield. The yield of the tested varieties Changsheng 07, Jingu 36 and Changnong 35 was higher. The suitable sowing date of combination of yield, agronomic traits and resistance, Changsheng 07, Jingu 40, Jingu 36 was May 13, Yanqi 13 and Changnong 35 were May 20. [Conclusion] The suitable seeding date of Yan’an millet was from May 10 to May 20.
