Abstract
Bag-controlled release fertilizer is a new type of controlled-release fertilizer designed to meet the needs of the large individual volume characteristic of fruit trees. The effect of bag-controlled release fertilizer on nitrogen (N) utilization, growth-rate, and fruiting was investigated using ‘Fuji’ apple trees (M. domestica Borkh. cv. ‘Fuji’/M.hupehensis Rhed.). The results showed that the available concentration of nutrients in the soil following bag-controlled release fertilizer treatment (BCRT) was more consistent than when application treatments were broadcasted. The BCRT significantly increased N use efficiency, where this was 2.7 or 1.6 times greater than one or four broadcasted treatments, respectively. Trees treated via BCRT were healthier and had more quality spurs due to more constant nutrient concentration in the soil. With the same application amount, the chlorophyll level and Pn content of BCR-treated trees were steadier and higher than those of broadcasted controls; thus, BCRT significantly increased both yield and fruit quality.
