Abstract：To study the allocation rules of the nutrients in scutellaria baicalensis in different phenological periods, ICP-OES analytical technique was used to measure the contents of 4 elements (Ca, Mg, P and K) in roots, stems, leaves, flowers and fruids in different phenological periods(such as dormancy period, leaf expansion period, blooming period, fruit maturation period and yellow period) simultaneously. The results indicated that the allocation of Ca, Mg and K in leaves was higher than in the other organs in the vegetative stage, in order to stimulate photosynthesis and generate abundant carbohydrate; there was a larger proportion of P and K in reproductive organ compared with vegetative ones in reproductive stage, and it was beneficial to multiplication, and in yellow period the percentages of Ca, Mg, and K in roots rose slightly to strengthen cold-resistant ability. This study results can help develop scientific and rational fertilization programmes for the cultivation of scutellaria baicalensis.
