Effects of stoichiometric ratio fertilization on leaf photosynthetic characteristics and fruit quality of blueberry.

ABSTRACT:

Aims

This study aims to accurately determine the fertilizer demand of blueberries during different developmental stages.

Methods

The ecological stoichiometry of C, N, P, and K in plant leaves is an important indicator of plant's ability to absorb and utilize its nutrient elements as well as mineral elements in soils. This work experimentally measured the theoretical NPK fertilizer requirement of seven-year-old rabbiteye blueberry 'Powderblue' according to their ecological stoichiometric ratios in leaves, along with photosynthetic rates and area. Calculations were obtained every ten days during flowering stage (S1), fruit setting stage (S2), young fruit stage (S3) and fruit expanding stage (S4). Different N, P, and K fertilizer gradients (1F, 5F, 10F, and 15F) were evaluated
