摘要
通过不同施肥处理,研究对掐尖大豆根瘤等生理指标的影响,结果表明:不同施肥处理对大豆的根瘤数有一定的影响,且处理间差异都达到了显著或极显著水平,而对初花期(R1)和盛花期(R2)调查的叶绿素含量、植株鲜重、干重、根系鲜重等生理指标影响效果不明显。
Through different fertilization treatments, nodules and other physiological indicators of topping soybeans were researched. The results showed that there was a certain extent of nodule number of soybean at different fertilization treatments, and the differences between them had reached a significant level. While the chlorophyll content, plant fresh weight, dry weight, root volume and other physiological index had no significant effects at the early flowering stage (R,) and the flowering stage (R2).
