Characteristics of Flowering Fruiting and Nutrient Requirement of Illicium verum

The major reasons for flower and fruit dropping of Illicium verum plants, the times of flowering and fruiting each year, and the period of time for fruit maturity were reviewed in this paper. The domestic research advances in the distribution characteristics of the main nutrition elements in the organs of leaf, flower and fruit, and the characteristics of internal nutrient balance of I. verum plants were concluded. The optimum content of nutrition elements in the leaves of I. verum was discussed. It was proposed that it would be essential to study the dynamic change of the plant nutrition along with the phenology, in order to find out the law how the nutrition elements in the leaves would vary with the phonological change, which will be more significant to guide the fertilization practice.
