农作物种子是第一生产资料,而种子的发芽率是种子质量的第一关键要素。如果种子的发芽率低,质量就无从谈起,更不能用于生产。合格种子的发芽率必须要保证在90%以上,也就是出苗率不能低于85%。在玉米种子的收购和营销活动中,首先要进行种子的出苗或者发芽试验,检验室试验种子的出苗率需7～12d,发芽试验最少也得5d。有时来不及做发芽试验,就要靠肉眼来判断了。用目测法直观判断种子的发芽率高低,只要细心观察,结合我们多年的一线工作的经验,具有一定的准确性,在收购和营销当中具有极大的参考价值。
Crop seed is the first means of production, and seed germination rate is the first key element of seed quality. If the seed germination rate is low, the quality is impossible to talk about, but can not be used for production. Qualified seed germination rate must be guaranteed at 90% or more, that is, the emergence rate can not be less than 85%. In the maize seed acquisition and marketing activities, we must first seed germination or germination test, laboratory test seed germination rate required 7 ~ 12d, germination test at least 5d. Sometimes too late to germinate test, we must rely on the naked eye to judge. With the visual method to judge the germination rate of the seeds, as long as careful observation, combined with our many years of first-line work experience, with a certain accuracy, acquisition and marketing which has great reference value.
