The invention relates to a sugarcane cross parent root-promoting nutritional agent and a root-promoting method thereof. The root-promoting nutritional agent is composed of a white root growth-promoting fertilizer, a calcium fertilizer absorption promoter, a trace element fertilizer, a frostbite protective agent, a rotten root protective agent and a base fertilizer containing nitrogen, phosphorus and potassium. The root-promoting method comprises the following steps: (1) phimosis, (2) conservation, (3) illumination treatment and (4) hybridization. The problems that in the prior art, the rooting effect is poor, consumed time is long, root system growth is not developed enough and the like are solved, white roots can be increased, the effects of promoting roots and strengthening seedlings are achieved, nutrient supply is sufficient, the survival time of sugarcane parents is long, and the seed quality is good. 本发明一种甘蔗杂交亲本促根营养剂及其促根方法，促根营养剂由白根促生肥、钙肥吸收促进剂、微量元素肥、冻伤保护剂、烂根保护剂及含氮磷钾的底肥组成；促根方法包括以下步骤：（1）包茎、（2）保育、（3）光照处理、（4
