Effects of Different Nitrogen Application Methods on Carbon and Nitrogen Utilization, Yield and Quality in Gala Apple Tree
A field experiment was carried out in Fifteen-year-old ‘Gala’/M. hupehensis Rehd. trees with 15N and 13C labeled tracers
to understand the characteristics of absorption
utilization
distribution
loss of carbon and nitrogen nutrition and fruit yield and quality under different nitrogen application methods (ON
TN and IN represented traditional one-time nitrogen
topdressing nitrogen and infiltrating irrigation nitrogen application
respectively) during fruit developmental periods. The results showed that the 15N derived from fertilizer (Ndff) in each organ displayed an order of IN > TN > ON at the fruit maturity stage
and significant difference was observed in Ndff values among the newborn organs (fruit
leaf and biennial branches). The total N contents and 15N absorption amount were highest in IN and lowest in ON. Compared with ON
the 15N utilization rates in TN and IN were increased by 41.63% and 68.60% respectively
and the 15N loss rates were decreased by 10.60% and 18.63% respectively. The residue amount of 15N-urea varied across different treatments and soil layers
showing an order of IN > TN > ON in 0-40 cm soil layer
and an opposite pattern in 60-120 cm soil layer. The ratio of 13C partition in fruit and storage organs (perennial branch
trunk and coarse root) under TN and IN was significantly higher than ON
and the highest value in the vegetative organs (leaf and biennial branches) occurred in ON
and lowest in IN. In addition
the yield
fruit hardness
soluble sugar and sugar-acid ratio quality index reached the highest value in IN. Our findings indicated that infiltrating irrigation nitrogen application could decrease nitrogen loss
thus increasing the absorption and utilization of nitrogen significantly by trees
and then optimizing the distribution of photosynthetic products
which was the preferred form to the yield and quality of apple tree.
