现介绍几种主要作物种子快速发芽法: 一、水稻种子去颖法:取试样2份,每份100粒,剥去颖壳后,放入30℃的温水中浸3小时,然后置于发芽床上,保持30～35℃的温度,两三天就可测定发芽率。二、棉花种子高温闷种法:先将棉种用55～60℃的温水浸3～4小时,然后倒去温水,闷种4小时,用湿毛巾卷起或置于发芽床进行发芽。一般在30～35℃条件下,经两昼夜就可测算发芽率。

Here are some of the main crop seed germination method: First, the rice seed to Ying method: take the sample 2 parts, each 100, after stripping the glume shell, into the 30 ℃ warm water immersion for 3 hours, and then placed Sprouting bed, maintaining the temperature of 30 ~ 35 ℃, two or three days can be measured germination rate. Second, the high temperature seedling cotton seed law: first cotton seed with 55 ~ 60 ℃ warm water soak 3 to 4 hours, then pour warm water, bored 4 hours, with a wet towel rolled or placed in the germination bed for germination. Generally at 30 ~ 35 ℃ conditions, after two days and nights can be measured germination rate.
