摘要
在25、30、35、40℃的不同温度下,取不同地点不同深度土样(活土)并对其进行灭菌与非灭菌处理,培养高粱种子,测定高粱种子发芽率、发芽势及发芽指数。结果表明,35℃为高粱种子发芽的最适宜温度。根际微生物对高粱种子的发芽率、发芽势及发芽指数有促进作用,在生长过程中通过施加含有根际微生物的底肥,可提高高粱种子的发芽率,利于丰产。
In this paper,sorghum seeds were cultured with sterilized and non-sterilized soil from different locations and different depth at 25℃,30℃,35℃ and 40℃.The process of the germination rate of sorghum seeds,germination potential and germination index were determined.The results showed that 35℃ was the most appropriate temperature for sorghum seed germination.Rhizosphere microorganisms improved the germination rate of sorghum seeds,germination potential and germination index.
