种子烘干是采用热空气强制将种子中的水分降至安全含水量以下,以减少霉变,保证种子质量等级和发芽率的工艺过程,是种子安全贮藏的一项关键措施。实践证明,经过合理烘干后的种子,新陈代谢的速度非常缓慢,能较长时间保持优良的种子品质和生活力,同时烘干还可以促进种子的后熟作用。种子在烘干过程中,由于内外因素的影响,如果处理不好,势必影响烘干的效果及发芽率,其简要技术要点如下:一是在种子烘干以前,应对种子进行清选,剔除 Seed drying is the process of using hot air to force the water in seeds to below the safe water content to reduce mildew, ensure the seed quality level and germination rate, and is a key measure for the safe storage of seeds. Practice has proved that after a reasonable drying of the seeds, metabolism is very slow, longer time to maintain good seed quality and viability, while drying can also promote seed after-ripening effect. Seeds in the drying process, due to internal and external factors, if not handled properly, will inevitably affect the drying effect and germination rate, the brief technical points are as follows: First, before the seeds are dried, the seeds should be cleared, removed
