【Objective】To provide a reference for the whole process mechanization of sugarcane production,the effects of different planting distances on the traits and yield of sugarcane varieties were studied.【Method】10 varieties were applied in the field tests for 7 years in a row,with 7 inter-row distances of 100-160 cm and models of 50 + 130 cm,and cane yields and characteristics were tested and recorded.【Result】The millable stalks number and cane yield decreased with dilating inter-row distances in the ranges from...
