发芽试验的目的是测定种子批的最大发芽潜力。发芽试验准确与否,对种子生产经营和农业生产具有重要意义。准确的发芽试验,可以帮助我们正确掌握种子质量状况,确保安全贮藏;避免销售发芽率低的不合格种子;可以做到精确播种、节约用种;可以通过农业行政主管部门正确、合理地行使质量监督权限,扶优治劣,保证农业生产安全用种。我们在发芽率检测过程中,发现那些发芽率不高或掺有陈种的种子,随着数粒方式(数粒仪计数和人工计数)、发芽床种类(沙床和纸床)、河沙种类(新鲜沙和重复使用沙)等的不同,对发芽率检测结果有明显影响。
The purpose of the germination test is to determine the maximum seed germination potential. Whether the germination test is accurate or not is of great significance to seed production and management and agricultural production. Accurate germination test can help us correctly grasp the status of seed quality and ensure safe storage; avoid the sale of unqualified seeds with low germination rate; achieve accurate sowing and save seed; and can use the correct and reasonable quality control of agricultural administrative departments Supervise authority, help superior quality control, to ensure the safe use of agricultural production. During the detection of germination rate, we found seeds with low germination rate or seeds mixed with seeds, with the number of grains (counting and manual counting), germination bed type (sand bed and paper bed), sand Species (fresh sand and sand re-use) and other differences, the germination rate test results have a significant impact.
