摘要:
以陇藜1号、冀藜2号、青藜1号为试验材料,分别在开花后15、20、25、30、35 d进行收获,研究不同收获时间对藜麦籽粒产量和物理特征的影响。结果表明,5次收获时间可分别对应种子的乳熟期、黄熟前期、黄熟后期、完熟期和枯熟期,各品种不同收获时间籽粒产量的变化趋势相同,均随着收获时间的延迟不断增加,至开花后30 d收获产量最高,之后又略有降低,开花后35 d的产量与开花后30 d的产量差异不显著,开花后25 d的产量与开花后30 d的产量差异未达极显著水平,开花后15、20 d的产量与开花后25、30、35 d的产量差异达极显著水平。同时随着收获时间的延后,收获的籽粒物理特性趋于向好,不仅籽粒体积(直径和厚度)、千粒质量持续增加,而且比重增大,籽粒散落性增强。由于藜麦籽粒成熟的不一致性和脱落性,以及种子易在穗上发芽,所以在生产实践中,可在开花后 25~35 d,即种子黄熟后期至枯熟期,根据天气等实际情况确定收获时间,趋利避害以达到最佳收获产量和品质。
