羊草(Aneurolepidium chinense)又名碱草。是我国东北及内蒙古分布较广的牧草,羊草适口性好、抗逆性强,但种子发芽率一般不超过20%。为了提高羊草种子的发芽率,我们进行了多种发芽试验,其中用清水浸泡方法可以使种子发芽率获得大幅度提高。具体方法是选饱满的羊草种子用纱布包好后放室温的清水中,水量是种子量的50倍,每8小时更换一次水,处理好的种子在27℃发芽箱内发芽。
Aneurolepidium chinense is also known as soda grass. It is widely distributed in northeastern Inner Mongolia and Inner Mongolia, and has good palatability and strong resistance to stress, but the seed germination rate generally does not exceed 20%. In order to improve the germination rate of Leymus chinensis seeds, we carried out a variety of germination tests, of which soaking with water can make the seed germination rate was significantly improved. The specific method is selected full of Leymus chinensis seeds wrapped with gauze and put in room temperature water, the amount of water is 50 times the amount of seeds, every 8 hours to replace the water, the seeds treated germinated at 27 ℃ germination.
