Abstract
This experiment was conducted to understand nutrient uptake of container-grown highbush blueberries in plastic film house. In March 2013, one-year-old 'Duke' was planted in a 180-L container mixed with peatmoss (130 L) and perlite (40 L), and hydroponic solution was supplied (fertilization) or not (non-fertilization) until October 2020. Hydroponic solution consisted of NO 3 -N 4.6, NH 4 -N 3.4, PO 4 -P 3.3, K 3, Ca 4.6, and Mg 2.2 mmol L -1 and the non-fertilization was supplied with only underground water. In October 2020, total dry weight of a blueberry increased 1.5-fold more in the fertilization than in the non-fertilization. Dry weight and inorganic nutrient content were the greatest in root than in leaf, shoot, old branch, and cane, indicating importance of root as a reserve storage organ. Fertilization increased dry weight by 2-fold and inorganic nutrient contents of root by 2.2 -2.6-fold. Total content of each nutrient in a bush increased 1.8 -2.2-fold more by the fertilization. In non-fertilized treatment, maintaining dry weight and nutrient contents for 8 years indicated that plants absorbed the nutrients to some extent through mineralization of peatmoss medium and underground water.
