进行种子发芽试验的方法多种多样,其共同点是必须满足种子发芽时对水分、温度、氧气等条件的要求,使试验结果准确可靠。设备较好的单位,常把发芽皿放在恒温箱内做发芽试验。设备较差的单位就用各种“土”法。我们在长期实践中对比各种“土”法,觉得纱袋沙土法简便易行,准确可靠。 (一)缝制纱袋。用医用纱布缝成宽1.5寸、长3寸的纱布袋(可视种子量多少而定大小),缝线 Seed germination test methods varied, the common ground is to meet the seed germination of water, temperature, oxygen and other conditions, so that the test results are accurate and reliable. Equipment better unit, often sprouting dish on the incubator to do germination test. Poor equipment units use a variety of “soil” method. We compare various “soil” laws in long-term practice, and think that the yarn bag sand method is simple, accurate and reliable. (A) sewing yarn bag. With medical gauze sewn into 1.5-inch wide, 3-inch gauze bag (depending on how much the size of the seed), suture
