Abstract Three different cultivation patterns of Newhall navel oranges including traditional cultiva⁃
tion pattern，wide-row and narrow-plant pattern，wide-row and narrow-plant fence pattern were selected and
the qualities of fruits under the canopy were analyzed to screen the labor-saving and light simplified cultiva⁃
tion patterns suitable for large-scale orchards of Newhall navel oranges.The results showed that the quality
of single fruit in the general cultivation pattern was significantly greater than that of the two innovative pat⁃
terns，and the quality of the upper single fruit reached（339.42±70.28）g. If the hierarchical differences
were not considered，the fruit shape index of the wide-row and narrow-plant pattern reached 1.08±0.057，
which was significantly greater than that of the wide-row and narrow-plant fence pattern and the general cul⁃
tivation pattern.The fruit juice yield of the wide-row and narrow-plant pattern reached（51.07±3.84）% ，
which was significantly higher than that of the wide-row and narrow-plant fence pattern and the general cul⁃
tivation pattern. In the wide-row and narrow-plant pattern，the single fruit quality of the upper canopy
reached（233.53±53.01）g，which was significantly greater than that of the middle and lower layers.The
soluble solids in the upper layer were significantly higher than that of the middle layer and the lower layer；
the thickness of the peel in the middle layer was the largest，reaching（0.52±0.079）cm，which was signifi⁃
cantly larger than that of the lower layer.The fruit juice yield of the lower layer was the highest，the content
of fruit Vc was the lowest.The titratable acid of the middle layer was the highest，and the solid acid ratio
was the lowest.In the wide-row and narrow-plant fence pattern，the juice yield of the upper layer was lower
than that of the lower layer，and the single fruit quality of the middle layer was the largest.The peel thick⁃
ness of the upper layer was significantly higher than that of the middle and lower layers.In the general culti⁃
vation pattern，the single fruit quality and peel thickness were larger.There was no significant difference be⁃
tween the upper，middle and lower layers.The fruit shape index of the lower layer was the smallest.The sol⁃
uble solid content was low，and the difference between the upper，middle and lower layers was not signifi⁃
cant.The solid acid ratio of the middle layer was the lowest.The Vc content of the lower layer was signifi⁃
cantly lower than that of the upper and middle layers.The fruit juice yield of the middle and lower layers
was significantly higher than that of the upper layer.The cultivation pattern had a significant impact on the
fruit quality，mainly in the quality of single fruit，the thickness of the peel，the soluble solids，the solid acid
ratio，the juice yield，and the Vc content.The canopy layer did not have a significant impact on the fruit qual⁃
ity of the wide-row and narrow-plant fence pattern，but had a greater impact on the wide-row and narrow-

plant pattern and the general cultivation pattern.
