测定稻种发芽率,就可确定稻种有无使用价值和正确计算播种量,可以促使幼苗出得早,出得齐,长得壮。现将快速测定种子发芽率的方法介绍如下:一、剥去种皮法;把稻种放在30℃的温水中浸泡3～4小时,然后用镊子轻轻去掉颖壳,注意勿碰伤胚部,摊放在毛巾或纱布(须经煮沸过)上,并用毛巾(或纱布)复盖,放在25°～30℃环境条件下,经常用25°～30℃温水洒在毛巾上,两天后就可发芽。
Determination of rice germination rate, you can determine the use of rice with no value and the correct calculation of seeding, seedlings can promote early, out Qi, grow strong. The rapid determination of seed germination rate is described below: First, stripping the seed coat method; the rice species in 30 ℃ warm water soak for 3 to 4 hours, and then gently tweezers removed husk, pay attention not to scratch the embryo Ministry, spread on the towel or gauze (to be boiled off), and covered with a towel (or gauze), placed in 25 ° ~ 30 ℃ ambient conditions, often with 25 ° ~ 30 ℃ warm water spilled on the towel, two Days after germination.
