| Abstract: |
| At the seeding rate of 45 000 buds per hectare and with ROC 22 virus-free seedling as materials，the
field experiment was conducted to evaluate the effects of row spacing（1.3 m，1.4 m，1.5 m） on the sugarcane growth，
cane yield and sugar content under oblique-planting model. The results indicated that the tillering rate，plant height，
single stalk weight，cane yield and sugar content per hectare decreased with row spacing increasing and there was no
significant difference among different treatments，but the sugarcane plant height of 1.5 m row spacing had significant
difference with CK and 1.3 m row spacing. Sugarcane stalk-forming rate，stalk numbers per hectare，stalk diameter，
internodes brixs of oblique-planting model increased compared with CK，and except the stem-forming rates of 1.4 m and
1.5 m row spacing，the other indexes had no significant difference. |
