烟草钾素营养研究进展

摘要

The .effect of soil properties on potassium nutrition,potassium fixation in soil,potassium accumulation and distribution,measurement of raising potassium in tobacco were reviewed in detail. Then, some questions which must be resolved now or in the future were discussed. Finally, further researches on tobacco potassium nutrition were also put forward.%从土壤特性对烟草钾营养的影响、土壤钾素的固定、钾素在烟株内的积累与分配规律,以及提高烟叶含钾量的技术途径等方面,综述了近年来中国烟草钾素营养研究的状况及进展,并提出了对烟草钾素营养研究方向的展望。
