用此法进行种子发芽试验,即使发芽最慢的水稻种子,也不会超过雨天即可出芽。其具体做法是:选取有代表性的样品,均匀混合后取出一定数量的种子,用干净的白纱布包起来,并用棉线扎紧,使扎线留出两条线头,各长15厘米以上。一条用来固定种包,另一条用来拴签。将种子放置35℃温水中浸泡,使种子充分吸水膨胀。浸种时间:小麦、大豆、谷子、高梁等为24小时;水稻、玉米为48小时。浸好种子后,进行催芽。取一只保温效果好的暖水瓶,先把软木塞打个孔,插上一支温度计,再往瓶内装半瓶40℃左右的温水,并把水面以上
This method of seed germination test, even the slowest germination of rice seeds, it will not exceed the rainy days can budding. The specific approach is: Select a representative sample, mix a certain amount of seeds evenly, wrapped with a clean white gauze, and tighten the cotton thread, leaving the cable tie two lines, each longer than 15 cm. One is used to secure the seed package and the other is used to tie the tag. The seeds were placed in 35 ℃ warm water so that the seeds fully water swelling. Soaking time: wheat, soybeans, millet, sorghum and other 24 hours; rice, corn for 48 hours. After soaking seeds, germination. Take a good insulation effect thermos bottle, first cork a hole, plug in a thermometer, and then to the bottle containing half a bottle of about 40 ℃ warm water, and the water above
