At the height of its production the Wushulin plant pressed as much as 1,600 metric tons of cane daily. Not only did Wushulin have a huge capacity, its products were of excellent quality and were specially designated for use by the Japanese royal household. As a result, the plant was much praised by the colonial "motherland."
在產能高峰階段，烏樹林製糖所每日的壓榨量高達一千六百公噸，不僅產量大，產品品質也非常優良，曾被指定為供給日本皇族專用，並因此受到殖民「母國」的表揚。
