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℃的条件下,经两昼夜就可测算发芽率。三、玉米种子切胚根法:取玉米种子2份,每份100粒,用刀片把玉米种子胚根尖端削去1毫米左右,使之露出胚根和根鞘的横断面,然后把种子浸泡3小时,捞出置于发芽床,在30℃的温度下进行培养,经两昼夜就可计算发芽率。
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 in the conditions of 30 ~ 35 ℃, two days and nights can be measured germination rate. Third, the corn seeds cut radicle root method: Take two corn seeds, each 100, with a blade of corn seed radicle tip cut about 1 mm, so that the radicle and root sheath exposed cross-section, and then the seeds soaked 3 hours, remove and placed in the germination bed, cultured at a temperature of 30 ℃, germination rate can be calculated after two days and nights.
