- Abstract:
- The 12-year-old ‘Youhou’ persimmonin plants were used as materials,the dynamic change of nutrient content in leaves was analysed in order to provide reference for the establishment of an efficient fertilization management model of ‘Youhou’ persimmon.The results showed that the content of nitrogen increased firstly and then decreased.Nitrogen content peaked at flowering of 548 g·kg-1.The change of phosphorus content in leaves was also similar.Changes in potassium content fluctuated more,peaked in mid-September of 205 g·kg-1.Calcium content in the leaves always maintained a gradual increase in the trend.Magnesium content gradually increased.Zinc content fluctuated slightly after the flowering stage drops to a low level.Iron content had no significant changes in the young fruit.Manganese content gradually increased.
