| 摘 要： | 通过1.3m行距与1.1m行距1年新植、1年宿根大区对比试验,结果表明：新植蔗1.3m行距蔗茎产量142335 kg/hm2,较1.1m行距（蔗茎产量148875kg/hm2）减产6540 kg/hm2,减4.4％,甘蔗含糖分增0.39个百分点,含糖量减285 kg/hm2、减1.5％;1年宿根蔗1.3m行距蔗茎产量126945 kg/hm2,较1.1m行距（蔗茎产量130335kg/hm2）减产3390kg/hm2,减2.6％,甘蔗含糖分增0.66个百分点,含糖量增330 kg/hm2、增1.7％.

| Abstract: | The field trials with two row space levels of 1.3m and 1.1m （control） were conducted at both plant and ratoon crop of sugarcane. The result indicated that the cane yield of 1.3m row space at 1 year plant crop was 142335 kg/ha, decreased by 4.4% （6540 kg/ha）, sucrose content increased by 0.39%, sugar yield decreased by 1.5% （285 kg/ha）; The cane yield was 126945 kg/ha, by 0.66%, sugar yield increased by 1.7% （330 kg/ha） decreased by 2.6% （3390 kg/ha）, sucrose content increased at first ratoon crop. |
