1试验原理植物体内的钾素几乎全部以离子状态存在于植物组织中,通常植株待测液直接在火焰光度计上进行测定,直接标定低标、高标浓度,待读数稳定即可进行测试。这种测定法测定误差相应较少,快速方便,结果准确可靠。2试验仪器和试剂火焰光度计、控温消煮炉、三角瓶、浓硫酸、300g.L-1双氧水(H2O2)、1000ug.mL-1钾标准
Principle of the test Plant potassium in plants almost all existing in the ion state in plant tissue, usually the plant solution to be measured directly on the flame photometer for the determination of low standard, high standard concentration, to be stable readings to be tested. This measurement method to determine the error less, quick and easy, accurate and reliable results. 2 test equipment and reagents flame photometer, temperature control digestion furnace, flask, concentrated sulfuric acid, 300g.L-1 hydrogen peroxide (H2O2), 1000ug.mL-1 potassium standard
