0引言甘草为豆科甘草属多年生草本植物,是一种抗逆性极强的沙漠植被,土壤酸碱度以中性或微碱性为宜,在酸性土壤生长不良。甘草喜光、耐盐碱、耐寒,主要分布于我国的东北、西北和华北。人工种植甘草既能有效恢复动态植被,又能达到节约用水、调整产业结构、促进农民增收的目标,是实现甘草野生资源可持续利用和保持生态环境的有效措施。由于甘草种子种皮角质硬实,吸水困难,种子自然发芽率较低,因此对甘草种子进行不同处理的发芽试验。
0 Introduction Licorice is a leguminous licorice genus perennial herb, is a highly resistant desert vegetation, soil pH is neutral or slightly alkaline is appropriate, poor growth in acidic soil. Licorice hi light, salinity, cold, mainly in China’s northeast, northwest and north China. Artificial planting of licorice can effectively restore the dynamic vegetation, but also to achieve the goal of saving water, adjusting the industrial structure and promoting farmers’ income, is an effective measure to achieve the sustainable use of licorice wild resources and maintain the ecological environment. Licorice seed germination test with different treatment due to the hard horny seed coat, water absorption difficulties, the natural germination rate of the seed is low.
